hi all ,ive had some trouble with my xfx pro 750w psu,ive just put together a i5 system and installed my GTX285 and when i use the gpu for 3d applications the pc shuts down ,ive been told that its the psu and have been looking at a new psu but i am on a very low budget being a single father of 2 kids ,i found this one on ebay http://www.ebay.co.uk/itm/180800042435?ssPageName=STRK:...

Input:

AC input Voltage: 95-132VAC or 190-264 VAC switchable
AC input Current: 7A res max. for 115VAC 60Hz, 4A res max. for 230VAC 50Hz
Overload protection :150%

Output:

+5V 30A
+3.3V 30A
+12V1 20A
+12V2 20A
+12V3 20A
+12V4 20A
-12V 1A
+5V/SB 3.0A

is this going to be good enough for my i5 system and the GTX285 ,i dont know much about 12rail voltages etc... but have been told i need 45-50 amps to run it all ,this one has 4 rails at 20amps im a bit confused do they all share 20amps or is it a total of 80amps ? many thanks in advance

Dual fans is always a bad sign.

Am I missing something in the advert? I can't find a brand name or model number.

Easily enough though it isnt 80+ rated or branded. I would really avoid it tbh.

I would reccomend looking for a 600/650 watt PSU which is 80 rated, looking around £50.

Its either spend a little and get something what MIGHT be decent or spend a little more and get something which IS decent.

Only '2 x 6pin PCIE for Graphics Cards' on a 800W PSU is another warning sign I think,

I wouldn't go with that, it's a generic PSU that in all probability will not output 800W and could damage your system.

Try trouble-shooting your issues. Stress-test your CPU with Prime95 and your GPU with Furmark, see if you have the same issue. If your system is new, then RMA your PSU and get a new, branded PSU as opposed to wasting money (and potentially your system) on junk. :)

Never ever buy a cheap PSU. Its just not worth the hassle of it failing.

ALWAYS look for 80PLUS ratings.

Recommended brands include: Corsair, XFX, Antec, SeaSonic.

That 750w XFX PSU you already have is packing an incredible amount of power (I have one myself) and it should be able to power your whole system about 3-4 times over. If the PSU is still new (within warranty), send it back for a replacement.

Any chance you can borrow another graphics card for testing?
There is a chance it's a graphics card problem and not the power supply.

Run away...

Seriously. You would be better off RMA'ing the XFX.

The thing you linked which looks vaguely PSU shaped will possibly destroy all of your computer components. Get a known quality psu to avoid future heartache.

I'm fairly sure XFX come with like 3-5 year warranty. You can't have had it longer than that? Contact XFX and arrange for a replacement. Don't pay out of your own pocket for faulty components.

Contact them and ask :)  Any chance you still have the box/packaging it came in?

Got to at least be worth a try :)  You wont know unless you ask...

I have no doubt that the psu is junk and dangerous. The specs and no name scream of problems.
It has the potential to not only destroy itself, but to take the rest of your parts with it.


XFX is a quality brand, of more than sufficient power.
If it works in 2d, I do not suspect a bad psu.

Do some more problem resolution work.

1) Are the graphics pci-e power connectors properly installed?
2) Excessive heat from 3d apps can cause a shutdown. Take the side covers off, and see if that helps.
3) Can you borrow or try a different psu in your pc, or, try your psu in a different pc?

You get the idea.

It certainly doesn't hurt to ask XFX. The worst they can say is no and that just puts you back in the same boat you're already in...

I don't suppose you thought to register your PSU when you first got it to get the extended 5yr warranty?

Start off by registering. See if the store you bought it from will give you a duplicate receipt, or if they will let you exchange it without the receipt.

If you are going to pay cash, and not keep receipts, register your product before throwing the receipt away. That's one of the things about online ordering I like. They keep a copy of the receipt on there.

I always staple or tape the receipt to the manual/users guide.
That's come in handy more than a few times over the years.

Solid advice there.

psu are the one thing that i dont mind going overboard on


its like breaks on your car

do you buy cheap generic ones that might when you have to do an emergency stop they do nothing

or do you pay extra and get ones that will stop you in less distance than standard breaks



in other words the more expensive powersuplies/good brands

have features in them that protect your pc components. i would rather replace a £50-200 powersuply than have to potentially replace all the parts connected to it

and the only parts not directly connected to the psu these days are:

low end graphics cards
cpu fans
some case fans
ram


thats about it


(edit - sorry my spelling is terrible)

thanks for all your help :)  after some days now of going back and forth with messeges to xfx support even without my reciept ,they have offered me a trade in of the broken psu for a new P1-650X-NLG9 for £34 which i am happy about ,glad i didnt go on and buy that crappy dual fan one i linked in my first post ,thanks again all :)
