Q: Power supply question for an engineer

Madam / Sir, on my Lenovo SFF desktop 510s-08ISH- 90FN00BYIN I have three sata ports for 3drives. There are 2 drives pre installed. These drives get power from a cable with two sata power connectors and are connected to the motherboard with a 4 pin plug. Can this 4 pin power connector on motherboard support 3drives ??Regards John

Should not be a issue. Drives these days do not use a lot of power. Only real concerns for power supplies these days is graphic cards and CPU's. If you Google PSU calculator you should be able to enter in all your information and get a correct answer.

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?













Solved!

Go to Solution.

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.

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.

alright,so right now i have a 250 watt power supply and i want to upgrade to 300 watts. my friend gave me his atx-730 300 watt power supply (made by enhance). I opened up my computer to replace my old power supply and while i was unplugging it i realized that my old power supply has a connection labeled "p7" which is 4 pin connector arranged as a square (2x2). The problem is, the atx-730 doesnt have one of these connectors. I dont know what this connection does or if i should continue without the p7 part. anybody know what i should do?
 

A:Power supply question, please help!

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 heard something about some power supply's are actual not the same output wattage they are rated as"?

i heard that it should be "heavy" if its atruly that wattage.

for exampel i have an OKIA-420ATX (okia 420watt max power supply), but it doesnt feel to heavy.
Is this a bad power supply? In my current computer i have a RAIDMAX 350 max power supply, and i dont know if thats enough, thinking of switching to my 420 one).

is the raidmax 350 enough for this?
also i have another computer with only 250watt power supply, and im thinking of upgrading it, i was gonna put in the okia 420 one, but dont wanna waste it on a less powerful computer if my 3200+ xp compuer needs it instead of the 350 power supply.

Ok, I just bought a DFI Lanparty mobo for my AMD 64 3000+.

Anyways, I set up everything and turned it on and it worked fine till I started to install drivers. After installing the drivers, I rebooted and my Power Supply started making a funny smell, and my UV case lights wouldn't work anymore, yet everything else still seems fine. My UV cases lights were actually plugged into the same power cord as my Video Card and HDD and they still seem to work fine. Could the smell just be the UV case lights burning out? Could it be my Power Supply? I'm confused.

So i was reading a review on a chassis/case i recently bought...and they said that the psu sucks (i kno, most power supplys that come with case's usually arnt top notch) but then he went into the +12V being a 15.0A..now ive always known about these numbers but never knew WHAT it meant..anyone want to explain? lol
 

A:Power Supply Question

A=amperage, power(watts)=volts x amps(current)

The 12 volt rail(s) run the video card, CPU, drives, and fans. Often the video card specs say about the amps on the 12 volt rail you need. It's much better to look at the rail specs of a PSU because some PSUs will have most of the power on the 5 volt rail and be rated high power like 400-500 watts. For a basic system 18a on the 12 volt rail should do, but for a gaming system with a single high end video card you want about 30 amps. With dual video cards you need to spend some dollars!

A:Power Supply question

Its hard, a 9600 isnt a power hungry ground breaking card, but a 250w is really low.

If you have the money I'd do it to be safe, otherwise if it would be a big struggle I'd roll the dice & stick with the current psw. I recon you'd be ok but you never know. Maybe someone would have a better insight here.

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.

my power supply is new to me (master power 520 watt)

i've been having a problem with random restarts or crashes during a specific game which i've never had before (WOW)

in hopes that its not my memory which is pretty new, i've been working on the heating issue. i took the side of my computer off and aimed a small fan in it which seemed to take away the problem. so i went out and bought a GPU fan which worked for awhile then the problem came back up. so i bought a new case fan which hasn't worked. when installing the case fan i realised that my powersupply has two fans, neither of which spin when the computer is on. i've looked everywhere on my comp for a control to get these things going.

i was wondering if indeed this issue is able to resolved in the BIOS or in Windows itself, or if my power supply is faulty?

any info would be greatly appreciated.

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.

You want to know if you can use a standard ATX power supply in your case? First we need to know what case you have. If you don't know, then you could also take a look at the PSU you have in there now and see what size it is. It will tell you on the sticker attached to it.

I am looking at new power supplies and was wondering if it pays to buy one larger than you need at this time?

Does a 550 watt power supply draw 550 watts all the time or only when needed? If they do not draw to their maximum capacity, it seems like it would be better to buy one larger than you need right now because the only cost would be the drive itself and not an increased electric bill and more heat.

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.

Newegg.com - COOLMAX ZX Series ZX-500 500W ATX12V v2.2 / EPS12V v2.91 SLI Ready CrossFire Ready 80 PLUS Certified Active PFC Power Supply 40$

If my system really only pulls 450w, would the 500w work?
more importantly, even if the 600w only runs at 75 percent, it should work also right?

I dont have 50 bucks to blow on a PSU. Hardly 40.

Anyone know of a great PSU for cheap?

Kind of along the lines of my first question but I would like to know if a mobo comes with a connection for both AT and ATX power supply if you switch the kind of power supply (in this case an ATX from an AT) and dont move the jumper on the mobo to acommodate this will it blow the mobo?
The motherboard is a

1st Mainboard VA 503+

Thanks,

I have a powermax power supply that I bought like a year ago at a local computer store. Ive been having an issue with it. It seems that sometimes it wont power my computer, it seems to power up and quickly shut off. If I change the voltage setting it works fine but my pc doesnt boot up it just powers on. The way Ive been getting it to work is that when it doesnt power on and stay on I hit the on off swith on the power supply itself. I put it to on and i push my power button on the front of my pc then it starts and stays on. Sometimes it doesnt work like that but rather after I toggle on and off the power switch on the power supply several times. I have no real idea what it could be. has anyone ever had something like this happen?

BTW I took the power supply to get it tested and it works obviosly.

I dont know if its my power supply or maybe a motherboard issue or what?

Please help
 

A:Power supply question

First of all STOP cycling the power on and off. You will make a bad situation much worse. Next replace the ps. Cold boot problems that go away after the first failed boot are almost always ps problems. Do not buy a cheap ps like powmax, deer, allied, foxconn, raidmax or any other cheap brand. Go with a quality unit like antec, enermax, coolmax, enlight, or sparkle. There are other good brands, however those are what I use in my builds.

Good day,
My power supply is making a strange noise on startup and after about 1 minute it settles, is there anything I can do about it besides replacing it?
The mother board connection is 24 pins and the power supply connection in the PC at present has a 20 pin + a 4 pin connector I do have a spare ATX power suply but it only has the 20 pin connector without the extra 4 pin connector, can I use that power supply in my PC?
Many thanks,
Brobilly
 

A:atx power supply question

1st of all define "strange noise". You need to post the EXACT make and model of the problematic power supply and the EXACT make and model of the spare power supply you have that you intend to use.

If your machine has a PCIe graphics card installed you cannot use the power supply with the 20 pin main connector. The +4 pin connector on the power supply with the 20+4 (pins 11, 12, 23 and 24) supply 75 watts of power to the PCIe bus.

I just got a new 500 watt power supply. The old one was overheating. The new one has a switch for a normal fan or turbo fan. The temperature runs around 48 C most of the time but has spikes up to 70 C (I have a temperature monitor software). When I put it on Turbo the system stays nice and cool all of the time. Is it going to hurt anything to leave it on Turbo all of the time? Thanks,

A:Power Supply Question

It will hurt nothing but your power bill (how ironic), and your ego if you are competing with someone for the quietest machine.

Of course, it may decrease the time before the fan bearings wear out, but I don't think that's a big concern at all.

I'm wondering if perhaps my random reboots are power related (all minidumps point to hardware). I can reliably recreate reboot when stressing computer through Prime95 or OCCT. I've bought a new PSU (cheapy I'm afraid) to no avail. I've read in other forums that it's really a key to have the +12v rail over 20 amps for Athlon XP systems (even though AMD recommends only 15-18 amps) which my new power supply isn't (old psu wasn't either). Any suggetions on the what amps are needed on the different rails for best, most stable results? Any help would be great. Here are my system specs (no overclocking):

Operating System : Windows XP Professional
CPU/Processor : Athlon xp 2600 +
Motherboard : gigabyte 7nf-rz
Hard Disk : maxtor, Space: 120 GB
RAM: 2 sticks of 512 ddr 2700
Video Card : Nvidia GeForce FX 5200
Video RAM : 128 MB
Sound Card : Soundblaster Live! Value
 

A:Power Supply Question

the amount of current on the +12V rail needed will depend on the PSU. on a cheap PSU, they "play" with the numbers to make the amperage and overall power rating seem much higher than it truely is. (they basically rate the wattage at an ambient system temp much lower than the average system really is) They also have more current on the 3V and 5V rails (which newer systems no longer need).

for now you should strip your system down to bare bones. Run it with just the CPU, 1 stick of RAM, onboard sound, and the boot hard drive (make sure that power cables are disconnected to all other unused components)

boot up and try to make the system reboot, if it doesn't... then add 1 component at a time until you find your problem

I have been looking at different power supplies but don't know what to get.
I have noticed that many have sinle rail, some dual and some have quad. Does this really make that much difference ? What would you suggest ? This going into a new computer so I can upgrade the video card. Probably 600w or more.
Thank you for your help.

I have a question about the +12 rating on a PSU. I have a 14A rating. Is a higher or lower number better. Reason is, I'm looking to upgrade my video card, but don't want to change the PSU too.
 

A:Power Supply Question

The higher the number the better. Does your PSU by chance have two 12v rails? If so, you can add the two together (but not the -12v rail).

It'll all depend on what you have, and what you are trying to put in. If you are wanting to put in a newer graphics card, you'll want to be up in the 24A range total on your 12v rail(s).

I have a Dell 8400 with 3.2 Pent. 4 ,SATA 160 gb HD. a CD/DVD RW drive,a floppy drive and a SATA PCI Host card to drive an external SATA HD. It has a Radeon X300 series video card. The system has a 350 w power supply. If I changed the video card to a XFXGeForce 6800GS would I need a bigger power supply.

hello,
i am planning to build the following MICRO ATX system

motherborad: Gigabyte GA-73PVM-S2H, GeForce 7100, Socket 775, MCP-630i, onboard graphics and audio
Intel Pentium Dual Core E5300, 2.60GHz, 2MB Cache, (775)
2 gb of ram
sata 500 gb hard drive
sata dvd re writer and a internal memory card reader
windows xp and may move to windows 7 later
i will power the monitor independently

I have a IN WIN BT611 case which has a 300 w power supply and dual 12 v rails. Do you think my system will be ok to run with the above following power supply ?
Its just that powersupply for these cases are hard to get hold off as they are quite bespoke,

Also, what do you think of the above combo for a new budget system ?

many thanks
 

A:power supply question

In Win is not in any means a reputable power supply manufacturer. If you're sure you want to use that exact case, then I'd recommend this power supply: http://www.newegg.com/Product/Product.aspx?Item=N82E16817151070&Tpk=tfx

Something like a Gigabyte 740G or 785G ATX board with an Athlon 62X2 5050e or 4850e would be my choice for a low-power system.. Especially the 785G has great upgrade potential and stability compared to an GeForce 7100 chipset board...

My friend has an HP Pavillion with an AMD Athlon XP that just all of a sudden stopped powering up. I haven't personally looked at it yet, but it sounds like the power supply to me. Its about 3 years old and he leaves it on 24/7. Anyways, he wants me to change his power supply for him. My question is What kind of power supply do those computers use? I mean like is there a certain type of mount or am i just gonna hve to open it up and take a look at it myself? Can i just get any kind? I've never taken apart a store bought computer and his warranty is up so he asked me to do it for him. I'm trying to price out a power supply but don't know what to look for.

Thanks in advance.
