Q: DC Input Power Supply (12 volt input)

HI,

Has any one modified a Power Suply to Take 12 volt DC Input?

I would very much like to hear from you, or any one you may of heard of that has done this.

I wanted to Put a desktop case etc. in my car and use it to listen to music...

Thanks to anyone who replies...

Preferred Solution: DC Input Power Supply (12 volt input)

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

A: DC Input Power Supply (12 volt input)

A standard Computer PSU rectifies the incoming mains (120 or 240 volt) and the "chops" it in a switchmode type power conversion.

Therefore as it starts with a high DC voltage (120 or 240 V AC rectified to DC) there is no easy conversion to make it use 12 V instead. Without a complete rebuild and redesign of the PSU.

By far the cheapest and easiest way is to use an off-the-shelf 12 V inverter that converts 12V to 120 or 240 V AC, and then you dont need to bother rebuilding the power supply from scratch.

Has the advantage of easily sourced power supply units for the PC. You would likely get away with a small 200 Watt unit.

Hey guys, I am thinking about upgrading my Power Supply to something with a little more grunt due to only having a Corsair GS800 (which does fine for now) powering 2 GTX480's. I have used a watt meter from the wall an I know if a PSU is pulling say for eg 600w from the wall, then your psu is outputting around 450w-500w.

I would like something with headroom, so I was wondering if you guys know of a good quality power supply for around ?150 - ?200 max, got to be modular and 1000w minimum

Thanks people

PS: when using Furmark and OCCT an the same time, I pulled 675w from the wall (i know Furmark is unrealistic when compared to games ect but I just want too upgrade for future use)

HI:

I have and "old" (ok, it IS old) Micron Millennia XS (1.7ghz P4) tower desktop. It has been working fine for years (left on continuously), but recently has been found shut off with it power light red instead of green. (Which normally indicates sleep mode.) It stays on anywhere from 2 hours to more than 12 hours. I've never caught it shutting off, so I can't swear it isn't going into sleep mode, but I can't get it to power up without unplugging the unit and plugging it back in and then restarting. (BTW, some power was definitely getting to the mainboard, as the small green LED on the mainboard was lit inside the computer.)

Anyway, I deduced it had to be: a) An OS issue (ruled out now), b) Heat Issue, or c) a Power Supply Issue.

Having rule out the OS issue, and seriously doubting a heat issue, I decided to try the PS issue (besides it's the easiest to test vs. the heat issue.) So, I went to use a PS from my even older Micron P3 700mhz that was not being used, however it did not have what appeared to be the right connectors, so I grabbed a PS out of a "newer" Dell XPS 3.0ghz P4 I wasn't really using. Here is where it gets weird ...

I go to pull out the PS from the Meillenia XS and discover it has the normal 20-pin mainboard connector, but ALSO a 6-pin (auxilliary connector one RED, two ORANGE, three BLACK, labeled "P8"). Now the motherboard also has the standard 4-pin +12v2 connector (two-yellow ... Read more

A:Need input from power supply/motherboard guru ..

First, I believe that Intel chipset 850 is the immediate precursor to the 8X5 chipsets, with Northwood P-4 CPUs, (845,865, ya da ya da yadda). However, I've seen references to an older socket, (423), as well as the socket 478, with 850 boards.

(Edit; I just researched this. It seems there is an adapter to allow the use of socket 478 CPUs in the 850 boards, which are socket 423).

PSU failure is very often accompanied by a failure to wake up from standby. The seem to run OK, but when you shut them down, the seem to "die of natural causes".

The, "you gotta pull the plug, and plug it back in before it will start" behaviour shows a failure in the "soft off" circuit.

I think there's an amount of +5 volt current required on standby. This is to keep USB "alive".

Before I would plug the 6 pin "aux" connector into anything, I would check the voltages. The red should be =5 volts, and the 2 orange wires MUST be 12 volts. The 3 blacks are grounds, keyed to the hot wires.

In a rhetorical sense, if the 6 pin block would plug in correctly, with the two orange wires to the 4 pin CPU block, (and they were in fact +12 volts), it would probably be fine.(Don't forget proper orientation, the positive terminals should be marked on the board).

In the real world sense, I'd definitely spring for another PSU, and not experiment with it.

I don't think the +12 supply directly to the CPU back then, was ... Read more

Important specs for my issue:
Motherboard: N-Alvorix-RS880-uATX (Alvorix)
video card: Integrated graphics using ATI Radeon 4200
Power Supply: Internal 250W (100-240V)
Expansion Slots: 1 PCI Express x16 slot for graphics card
Product number (to look up anything else): BV564AA

I got my HP Pavilion p6716f pretty cheap and I'm starting to understand why now. I'm trying to upgrade the hardware, specifically the video card, and after googling the crap out of video cards I've realized I'll need to upgrade my power supply too. My question is how can I be sure what power supply will work in my pc and what wattage would be recommended? I've tried my best to figure this out on my own but I've hit a wall.
I don't know if this makes any sense but because the motherboard and processor are AMD I was thinking of sticking with an AMD video card, probably in the 6000 series, problem is I dont know if it'll fit in the PCI Express x16 slot, take a look by looking up the product number on hp (id post the web page but this website won't let me) So there's my first problem.

Link to specs here.

Motherboard picture:

Looks like any PCI express 16x GPU will fit fine, as long as you don't mind losing one of the PCI Express 1x slots for double width GPUs.

It has an ATX power supply, so that should cover pretty much anything you replace it with, but deeper power supplies might be hit and miss and you'd need to measure whether they would fit. ATX format power supplies are made to industry standard dimensions in terms of height and width, but different ATX power supplies do differ in depth. So an ATX should fit, but ultimately it depends on how much space you have between the back of the case and the back of the DVD drives for clearance.

The power supply you choose is dependant on the GPU you choose. If you could let us know the following, we could help you select the best option for you:

1. Your total budget, for a power supply and graphics card.
2. The intended usage of the computer -- if its gaming, what sort of games?
3. What resolution and detail do you wish to play these games at. The max resolution is dictated by the max resolution of your display, but it is an important factor to consider.
4. If you have preferred shops, list them. Newegg is fine if you like to shop there though.
5. How many fans does that case have, and where are they located -- upgrading to a higher end GPU introduces heat into the case in most cases, so cooling must be considered.

Really having some wonk issues with these last two Lenovo products I've bought. It's nuts. Latest weird thing that's happening seems to be some sort of unintended input. Occasionally, I've had the focus repeatedly stolen from an input field I was typing in. I have to click on the field several times, only to have it taken away again, like the mouse is clicking elsewhere. (I've been having issues with clicking things accidentally firing double-clicks--maybe my mouse buttons are faulty? Both the X1E I returned and this X1C have done that.) The other strange thing that's happening is that in iTunes, if I pause my music, it will resume itself 5 seconds later, like the play button some keyboards have was pressed. But this keyboard doesn't even have that, as far as I can tell. It feels like my computer is inventing input. It's maddening.  Any clues? My opinion of Lenovo products has sharply dropped these last couple months.

Hi there @145755, I hope you find your Support Forum experience a positive one!  It is a great place to find the help you need, from other users, HP experts, and other support personnel.  I understand that you have changed a setting on your computer and now the display is not working.  I am happy to give you a hand with this. Please post the full product number for your computer. See the following, if you need help with that information.  HP Desktop PCs - How Do I Find My Model Number, Serial Number or Product Number? I would suggest you try to start your computer in Safe mode to load basic screen settings. See this document: HP PCs - Windows Safe Mode (Windows 10, 8). As you are unable to see the display properly at this time you will need to follow the process described for "Entering Safe Mode without access to Startup Settings".  If you are able to get in, then make the needed adjustments to your display settings, then restart your system normally to see if the display will come up properly. If not try a different screen resolution. Please let me know whether that works for you, and if it does resolve your issue, please mark this post as a solution. Kudos would also be appreciated.

I have a Dell D610 laptop w/ XP Pro SP2... or had.

I have a corrupted registry entry hosing the keyboard input. The mouse works fine up until the point when I kit the first key on the keyboard when under the Graphical Windows interface. After I hit any key, the mouse freezes as well. This happens if I use the laptop keyboard or an external keyboard connected to a PS2 jack.

I have performed hours of troubleshooting and it is not the keyboard hardware. Keyboard input works during all non-graphical UI (BIOS, Recovery Console, etc.). I even removed the drive and plugged it in to another computer. I made a copy of the WINNT\system32\config files (sam, default, security, system, software) and replaced them w/ a copy of these files from WINNT\repair. The computer boots to Graphical Windows and I am able to type in this session just fine.

How can I "erase" the keyboard driver corruption in the registry (or perhaps a corrupted driver file or set of files)? The problem is that I can't boot the system to a point where I can edit the "corrupted" keyboard entries. I can't use the Recovery Console because I don't have the Administrator password. So I tried to install SP3 from a bootable CD. The minute it asks me to type in the Product Key (a graphical dialog box), input is frozen a the first keystroke (even a key like Caps Lock). Can I actually edit the registry that resides on the boot drive while it is connected to another computer? Any other suggest... Read more

Hi,
Sorry for the silly question, but I am really lost with Windows 8. Did a quick search, but nothing came up (Keyword will only result in how to set input in Win8, not the problem presented here).
 
 
Here is the issue.

The short version of the question is how do I move the #@#[email protected]%$#^%$ (display gibberish somehow, boxed in red below) input method above Microsoft Pinyin, while keeping English as my default Display language and Input language.
Longer version here:
I use English and Chinese input, but the default MS Chinese input is "inconvenient", so I installed another input software for Chinese input (the gibberish above, or lets call it method ABCD).
The order I want is English as my default Input method and display, while ABCD as my default Chinese input (when I hit Alt + Shift, should switch from English to ABCD). However, since I can't get ABCD above MS-PinYing, when I Alt+Shift it auto switch to MS-Pinyin, not ABCD (Manually switch from MS to ABCD gets annoying).
In WinXp/Win7 I only need to manually switch to ABCD once, and the system remembers it, but Win8 for some reason automotcally load the language list on every start up =/
Also in WinXp/Win7, I can delete MS-PinYin while keeping ABCD (so I only have English and ABCD), but Win8 doesn't allow me to do that as I must have MS-input or the second line (highlight in green) in language perference doesn't even appear.

I've been fiddling with this on and off for months, but I don't  know if the problem is with the touchscreen, Windows 10, the drivers, my software, or some combination of those, so none of my troubleshooting has really gotten me anywhere. I bought the Flex 5 and the active pen intending to use the touch screen like a Cintiq monitor, in addition to the Huion graphics tablet I already own, but any pen input just reacts like touch input, making imposible to work comfortably in any painting/animation programs. I also can't figure out a setup that will let me use the active pen and my tablet at the same time; Huion and Wacom drivers don't seem to play nice with each other, so I can't have them both installed at once if I want either of them to be recognized in my software and have pressure sensitivity. I have turned off "tablet mode" in Settings, and in the Control Panel I've disabled "Flicks" and "press-and-hold to right-click". Regardless, using either the active pen or my tablet (which doesn't even interact with the touch screen) will make my computer react like I'm using my finger -- same visual feedback, press-and-hold still right-clicks, dragging with the pen will scroll around the webpage/canvas, etc. Depending on the software I'm using and which drivers are currently installed I can sometimes draw and get pressure sensitivity, but I'll still keep accidentally triggering touch commands with the pen that interrupt my work flow. Even if it's at the cost of touc...

USB, even USB3 was never meant for transferring large amount of data needed for HD video, too much conversion has to be made. Laptops are limited by number and type of outputs but desktops can accommodate multiple video cards and even basic cards with Display port that use power of existing GPUs to provide video signal to more monitors or TVs.

Here's the situation. I have this old mITX computer I built a few years ago that I'd like to hook up to Dad's big-screen TV so he can Skype from his living-room. Problem is, the computer is VGA only and his TV is HDMI only. The MoBo has just one PCI (not PCIe) slot with a maximum output of 75watts.

I tried a PCI video card with HDMI output, but the slot couldn't drive the card. Didn't even detect it.

I believe DVI uses less power (the cards are definitely cheaper), and I could just use a simple DVI-to-HDMI cable. A native HDMI port would be better. As long as it works, I don't care. But w/o an external power input, the card can't draw more than 75watts from the PCI slot.

Anyone know of a card that fits this very specific bill? Thx.

ADDENDUM: PC only has a tiny 300watt PSU.
 

A:I need a PCI (not PCIe) DVI card (either <75w or w/power input)

Check this one out: Zotac GeForce GT 610
It is a PCI Card (non express) that has DVI / VGA / HDMI. It is also a Low Profile and requires a 300w power supply or higher. It looks like it should work with your situation.

Try first:  Replace the adapter.  That may solve the problem.
If not, the jack may be replaceable (it is on most newer systems;  we'd need to know the exact model number to tell for sure - i.e., Inspiron 5521, etc. -- not just Inspiron 15).

If you move the power cable around with some pressure... then the charging light will come on. I believe the slot on the laptop where the power cable is inserted is broken some way. Is it easy to get to that piece and remove/ repair it? If so how do I do it?

hi,

I've got a Dell Dimension 8200 Desktop I've had for about 4 years, but the monitor seems to flicker now and often goes black and I can't bring it back. Sometimes itll come back if I let it sit for an hour or so.

But, I got a new flat panel monitor - same problem except the monitor goes black without flickering

I also tried installing a new video card (AGP?) and same deal.

Any ideas / hints on how to fix this? Thanks so much guys.

So my computer is about 4 years old, it is a Sony Vaio PCG-984L.

I cannot charge the computer because there is a problem with the DC IN

i believe it is missing something that allows there to be a circuit between the power cord and the notebook but it appears to be missing.

you can see that the adapter chord has one metal stick

its supposed to go into some sort of contraption for that will give a current to the two sticks in the laptop.


also, this item fell out and i was able to charge the computer but had to press hard on the adapter. after a while it stopped charging. iff that info gives any help

Hi, my laptop won't power up. There is a flashing white LED next to the in jack where the AC Adaptor plugs into.  The light flashes 3 times. The light is not on the adapter, it's on the laptop. I left the laptop plugged into the power supply all day, went out and now it won't power up. Thanks,monks

A:Flashing white light next to power input

Hello, Please try hard reset first :  Shut down the notebook, unplug the AC Adapter and then remove the battery.  Hold  down the Power button for a full minute.  Plug in the AC Adapter ( leave the battery out for the moment ) and see if the notebook will start.  You might want to take a look at this document: Battery Does not Power Notebook or Hold a Charge. It suggests troubleshooting steps to determine if the problem is the battery, the power supply, or the system board.You might find the answer to your battery/power issue as you work through the steps in that HP support article. Hope this helps, for any further queries reply to the post and feel free to join us again  **Click the White Thumbs Up Button on the right to say Thanks**Make it easier for other people to find solutions by marking a Reply 'Accept as Solution' if it solves your problem. Thank You,GBL84I am not an HP Employee

I'm going to assume this is a hardware problem. I'll start from the beginning. I plugged in my cell phone via a USB cord to transfer some stuff to it, and everything on my computer froze. My keyboards backlight turned off and my mouse wouldn't respond. Nothing was doing anything.

I shut down my computer using the power button on the front. It started booting up, I could hear the fans and the hard drive, but nothing turned on. The keyboard stayed unlit and the monitor didn't even come on. It's like nothing is getting any power. I'm starting to freak out a little bit....

I'm running Windows XP Home dual booted with Ubuntu Hardy, Dell Dimension 3000, 2.8Ghz P4 processor, 2GB RAM, ATI Radeon 9250.

Any idea what's going on? Any help is much appreciated.

Thanks

I have a Compaq Presario 2100. well the power jack broke off the motherboard, while trying to solder it back in place, one of the prongs bent, so I was taking it out again to start over, when my friend bumped into me. I accidently pulled it out of the motherboard. While inspecting the prongs, it looks as though a copper looking "sleeve" was still soldered to the prong. Is there anyway to fix this?

Also, the original jack was lost. I have another one, it's not a replacement, but it fits the plug. How can I solder this to the mobo for it to work?

Please help me.

That message is coming from your monitor itself I believe and not from the computer.

Its saying that there is no video signal, which idicates that the computer has probably not even booted up?

Is the computer actually booting (keyboard lights flash, HDD light flicking) after you power it on?

Hi, I recently let my friend borrow my Lenovo V570 laptop while I was out of town because he wanted to fix the keyboard which did not work at all. The keyboard was removed and reinstalled with a new one but a worse problem was created. The power button cable was removed and the plastic piece that locks it was lost. I cannot afford to pay for computer repair or a new motherboard, I know its still good since the battery light is on and charges when plugged in.

Now I cannot turn on my laptop at all and I need it for school ASAP. I read through the maintenance manual many times for this laptop but it does not say exactly what each one of these inputs are for. So my plan was to remove the plastic lock from the cable for the touchpad. At this point I dont care if the keyboard or touchpad works (I will use USB keyboard and mouse) I just need to be able to power it on and working USB ports.
So I unplugged the plastic lock from the input I believe was the touchpad and tried to install it in the power button cable input since it looks like the same size. Problem is it is very small and difficult to work with and when I tried to install it I slightly bent one of the pins (shown in photos below.

If I carefully straighten out the pin on the cable input and try it again (any tips would be appreciated in doing this) do you think the plastic lock I removed will fit in the power button cable input? Also are these plastic lock pieces hard to find if I need a replacement?

Also does anybody k... Read more

Hi there,

Newbie to this site, but hope you guys/gals can help me out. I've had this laptop for about 4 years and ironically, the extended warranty ran out only 3 weeks ago.

3 problems:

This evening I turned on the laptop for about 15 mins and noticed the power light indicator was blinking on and off. Soon smoke started to come from the power/network port area and the system immediately shutdown. I immediately pulled the AC adapter out and allowed the system to cool. Upon disassembling the laptop, I could not find any burns on the board near the power/network port area. Is it safe then to turn on the laptop again? Anyway to isolate what caused the problem?

2. The AC Adapter has been problematic for awhile. It appears to be loose and will sometimes cause the laptop to auto shutdown due to loss of power. I often to jiggle this wire to allow it continue to provide power. How do I test if the problem is w/ the pin on the m/board or the external adapter?

3. The battery on the laptop has also not been working on its own for awhle. When ever I pull the battery out, it shows that a little bit of juice on the indicator, but when I remove the adapter and let the laptop run on the battery alone, it shuts down w/in 2-3 minutes. How can I test to see if the battery is still fully functional?

I really don't want to have to take the laptop into a service center so they can screw me over w/ diag costs and unnecessary parts - so any advice would be much appreciated.

Thanks!... Read more

This is not really a problem, just a question for my own education. I recently helped a friend's son get his home build running. Along the way I discovered that a typical gaming capable machine needs a LOT of +12 volt power. I don't think I would have any trouble starting my car from the 12 volt rail of his power supply.

So, what the heck does all that 12v power get used for? My hardware knowledge is very dated, but I'm used to thinking in terms of a couple of volts or so for most of the circuitry. The video boards seem to be the big user, but at the end of the day they're still mostly some dedicated processing and a bunch of memory, neither of which I would have expected to use +12v at all.

So...?

Hi everyone,
thanks in advance for any advice,
this is more an electrical issue rather than a computer issue, but hopefully someone can help??
I brought my HP desktop with me from the UK to Japan.
Its a HP Pavillion t3777 uk model.
UK uses 240 volt AC ~ Japan uses 100 volt AC
The label on the back of the CPU box says:
A/C input 50/60 hz
100-127V ~ 6.0 A
200-240V ~ 3.0 A
Which makes me think it should work OK
but next to the power cable socket there is another label that has a warning triangle and says :
230V HI-POT OK
All I know is that when I plug it into the mains in Japan nothing happens.
I think there are 2 options - get a step up transformer or change the power unit inside the cabinet.
I was wondering if there is some sneaky switch anywhere that flips it into Japanese power mode ??
Many thanks,
Rumi

230 watts is the maximum power supply, it only supplies the power needed by the computer. I sold my W540, so i can't test this for you. But i do the use the ThinkPad X1 Carbon with the 230 watts power adapter without any problem.

I have 2 failed Z800 power supplies (1150 watt version). After some internet research I am led to believe this is a common problem and related to the PS capacitors. Since I do not know how to do this capacitor replacement (yet). I thought I would buy a new PS. However, I do not want to buy a Z800 PS since it seems to me to be a defective design. Can anyone chime in and tell me if the new z840 1125 watt PS will work with my older z800? I have called HP support and spoken with the correct support people on this and they were not able to confirm if the Z840 PS will work (fit) on the z800. The closest confirmantion I recieved was that if it fits then it should work. Instructions to fix the capacitors:http://h30434.www3.hp.com/t5/Business-PCs-Workstations-and-Point-of-Sale-Systems/Z800-power-on-issue... Same issue I am facing:https://www.youtube.com/watch?v=f563JGeoxaw On a side note, can anyone recommend a good service tech to make such capacitor repares in Southern California or insrtuctions on how to make this repair (with pictures). Thanks
