Power Supply Question - Can I use the 230W power supply with a W540?

Q: Power Supply Question - Can I use the 230W power supply with a W540?

I have a W540, which currently uses a 170W power supply (20V 8.5A) I also just recieved a docking station for a P50 which has a 230W power supply showing 20V 11.5A. The connectors look the same, but I'm hesitant to try the 230W power supply in the W540. Should this be ok to use the 230W power supply with the W540?

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: Power Supply Question - Can I use the 230W power supply with a W540?

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.

Once again my PSU for the W540 failed. It's now out of warranty, and wondering what third party replacement is available. The main issue, is that I want an LED on the brick, or jack, to tell me when power is good (eg: blue, green or red LED).  The OEM brick is a black box, with no indication the power is OK.  I often had to go from outlet to outlet to find a good one, in public place.  Just hate having to set up the laptop, just to find out the power is not there. Thank you for anby forthcoming help on this quest!

I am sure that you can located one in China for fairly cheep, especially since they are probably made there anyway, and then upon your return, have the original replaced under warranty.     Ask around, there must be a computer outlet somewhere that sells parts that can locate one for you in China.    It may be a knockoff, but it will get you by for your trip, just make sure the voltage/amperage match that printed on the original.

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

I have a server that I would like to upgrade to 20 1TB Hitachi HD's. They claim max startup current of 2A. and idling down in the .5A range. The platform will be a 775-series X48 with a 6600 Core Duo. Graphics card is small, does not even require aux power connector. Not needed to just supply the KVM with 1280x1024. No other signficiant sources of 12V drain exist other than the MB/CPU, a slim CD-Drive for installs, a slim floppy, and one additional 30GB SSD startup drive (2W when active).

I am looking at an 850W Corsair. I've heard these are quality supplies and I don't want multiple rails since no one really knows what sort of Voodoo goes on as to how they divide multiple rails up. And I don't want to get into that. I will be using a single-rail +12V PS. I can add a second if I need to but I'd rather not.

Do you think this will be sufficient for handling 20 Hitachi hard drives? "Green" drives are a non-starter since they will drive my Raid 6 controller, and then me, off the deep end with TLER issues. I do have staggered spin-up control of the drives with the controller.

Thanks for any help.
 

A:Power Supply Question & HD Power Consumption

Power Supply Question & HD Power Consumption, Pt. 2 - Laptop vs. 3.5"

My second question is this - I have a BTV server that needs to be on at all times during the season to record shows during day and evening.

Suffice it to say that you CANNOT reliably put one of the critters into sleep/hibernate mode and expect it to wake up and reliably record a show. It just won't happen.

Now, this is one case where I can use "Green" 3.5" drives, but I am also considering banking 500GB 7200RPM or even 5400RPM laptop drives. These will all be on a raid controller, but since they will be in pass-thru mode or RAID 0 mode the controller won't freak over TLER like it would with RAID 5/6 and mark the drives bad. The controller also has more than adequate cache to handle a 5400RPM spindle as OTA HDTV generates little more than 2.5MB per second per channel. Even 4 channels at once is 10MB/s and that should not tap the ability of a 3Ware controller with cache on 5400 RPM RAID 0 or even pass-thru drives.

My question is this - 2 500GB laptop drives burn much less startup and idle current than a single 1TB 3.5" drive. Has anyone tried running multiple laptop drives on a RAID controller, and what sort of luck have you had? What sort of sustained throuput can you obtain?

Electricity is a huge factor here, at 12 cents per KWh. I can recover the marginal cost of 2 500GB laptop drives vs. 1 1TB 3.5 drive.

A:Hp power supply question

The easiest and quickest way to test the power supply is to take the tower to a shop where they have a power supply tester.

They can test the power supply and if the power supply is defective they also can "jump" a known good power supply to the motherboard to make sure that when the power supply failed it didn't take out the motherboard.

I do these tests quite often in my shop, takes about 30 minutes total time and the cost should be minimal perhaps $25-$30.

Alright I'm a little frustrated right now but it might actually be a good thing. I was planning to buy an ULTRA X3 800w power supply from TigerDirect.com but when I looked today it was listed as unavailable, just my luck. The unit was listed at $199.xx and came to about $215 with shipping.

Anyways, I've been searching around and there are few retailers that sell this unit; it's been unavailable from ULTRA's online store. However, while I was browsing more listings I came across a sweet deal for the X3 1000w model, only $205. This model is listed on Tiger for $299 plus shipping. So, I just bought the unit because it was almost what I would have paid for the 800w on Tiger, came to $222 with shipping.

My question is, 1000w is probably way overkill for my system, would a PSU this powerful (70A on a single 12v rail) damage my system's components if I were to use it anyway? I think I need a minimum of 700w for this system - Intel q6600, two 8600GT's in SLi, three hard disk drives and two DVD drives. Not a very power-hungry setup so I am a bit worried about using this PSU. Any input on this would be greatly appreciated.
 

A:Power Supply Question

Wait for a second/third opinion, but I believe it would NOT, as the system would only draw the power needed from the PSU.

Hello,

Trying to diagnose a computer problem.

The computer does not boot up. It starts, and all fans are spinning, and the HD ( I tried 2 hard drives actually) seems to be spinning.

I am wondering if the PS is failing?

If the PS is done, will you get ANY power at all, or will you press the on button, and get no juice?

Also, there is no burning or "heat" smell coming from the PS.

If it is not the PS, my next guess is the MOBO, but I am not really sure how to test if a MOBO is pooched.

Thanks in advance.

Does anyone here know if the talk I've been hearing about GF4 Ti's needing a minimum of 300 watt's with the power supply is fact or if it is some peoples idea of problems with compatability on certain systems? I went to the Dell and Gateway websites and they offer the 4600 in their systems that are powered by 250 watt supplys. I was hoping to find some facts on this. Also no reviews ever mentioned it.
 

A:GF4 Ti & Power Supply question

Everyone gets pretty confused about this. No, the card in itself does not require 300w, but will draw apx. 50w & up to 75w under load (extreme gaming) However, adding another 50w draw may tax your system, necessitating a 300w psu, or better.

Nope. If your motherboard has a 24pin connector, and your PSU only has 20pins, it's not a good combo. Return the PSU before your computer suffers irreversible damage, and get the proper type of PSU.

I have an old Dell 0M3918 Motherboard that has the original power supply. I'm looking to upgrade that power supply so that I can have more power, and most of the power supplies I've seen are 20 pin connectors. The board uses a 24 pin connector. Are these new PSUs compatible with my board? I can see they have a 4 pin connector that's 2x2, and my assumption is that you use that as well, but my PSU has one of those anyway and its currently plugged in at a different spot on the motherboard, well away from the main 24 pin connector.
 

A:Power supply question

All the 24-pin power supplies I've seen have a detachable four-pin part to make it compatible with the 20-pin boards. (The wiring is the same on the first 20 pins.) It usually is not visible in the product pictures; but, it is there. I have seen some detail pictures of supplies at NewEgg.com where you can see the demarkation point between the 20-pin part and the extra four pins. That's where it breaks.

As for the extra four-pin connection, that is separate entirely from the twenty-four pin part.

You can see fairly detailed pictures at NewEgg.

If that cable was just 'there' without being connected to the motherboard, don't worry about it.
It is only needed for Intel P4 CPUs and lately also for AMD64 S939 CPUs to supply extra power to the CPU. A motherboard that requires it would have a matching receptacle for it.

hi, i just bought a new HP model Desktop PC, the a6112n Desktop PC, and it has a M2N68-LA motherboard, and a 250-W power supply. i want to upgrade the power supply so i can run better video cards, but im worried that it might fry the whole computer. the info about the computer can be found here:

http://h10025.www1.hp.com/ewfrf/wc/...0883&cc=us&dlc=en&lc=en&jumpid=reg_R1002_USEN

and info about the motherboard can be found here:

there was also a bit of discussion about upgrading a video card in another thread, and the person asking the question was using the same motherboard. somewhere in the thread the user mentioned having a 700-W power supply. i want to know if i can upgrade to something similar, just not as much. here's the link for the discussion, if that helps any bit:

I have an ancient ASUS P3V4X mobo, it's fine, and I upgraded to a higher wattage PS 2 days ago, a Sigma 550, since I have a DVD Burner, 2 HD's, Sound card, NIC, AGP video, etc. The 'old' PS was only a 250w unit, hence the upgrade.

The new one works fine, but I noticed in the BIOS I was looking at the voltages, and they are as follows:
VCore 1.71v
+3.3 3.50v
+5 4.87v
+12v 13.38/13.45v (it fluctuates)
-12v -11.59/11.67 (it fluctuates)
-5v -12.00v solid.

I don't get the -5v as showing -12.00v, it's solid, never fluctuates, and I'm not even sure what a -5v is for. ( can set it to ignore if I choose)
I do NOT use SATA drives, just your standard ATA Maxtor's, and I do NOT have a PCI-Express video card.

Any ideas on why the -5v shows a -12.00v ? Nothing is burning - yet.

I have a Antec PP-303XP power supply and my problem is this. When plugged into a system board I can power it on just fine but, when I try to jumper the 14 and any black connection the power supply does nothing. I am trying to use this to test some other equipment that I have and I don't want to have to keep turning the system board off and on and mess something up. Any help would be appreciated.
 

A:Power Supply Question

Standard protection circuits for a commercial home user machine. You need a better power supply that is engineered to handle such things.

I did a check to see how much power my computer needed and apparently it needs 38w. Is this right? It has a max output of 230volts and i am looking to get a new video card, i know i will need a new psu you to sufficiently power it, i might get a 400. Would this be enough? Thanks
 

A:Power Supply Question, 38w?

Where di you see the 36w at?
For a typical desktop, you're probably looking around 300-400w, but then again, if you tell us the computer specs, you could get an answer with better accuracy

Hello all, I am planning to get new hardware later:

- Motherboard: MSI H57M-ED65
- Intel Core i5 750
- Asus ATI 5770 1GB
- 2x2 GB 1333MHz or 1600MHz, Corsair

I have a question: how strong power supply I need for those hardware?
Thanks in advance.
 

A:Power Supply question

There is more to a pw supply than simply a wattage rating. For your hardware, I would use something like this corsair unit

I bought a new video card today, took it home and installed it. It didn’t work because I need to connect it to my power supply… Silly me… The video card box says a 300W or higher power supply is recommended. Mine is only 250. My question is, can I use the video card with just 250W’s or is the 300W’s a must? If I need 300, can I just buy a 300W power supply or do I have to upgrade something else along with it?

But this one has to do with another cumputer here at work...

The power supply to one of the computers here at work is dead. Our tech guy came and took it with him but just called and lesft me a message asking how many pins the power supply has.

How/Where can I find this information?
 

A:Another Power Supply Question

If he has the power supply with him he should know how many pins it has. If he's asking about the main plug on the motherboard you can count the number of holes. It will either be 20 or 24.
