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:...
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%
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
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.
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.
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?
"2 year standard warranty applies with all PSUs - simply register your PSU when purchased at http://xfxforce.com/en-gb/Help/Support.aspx to obtain an extended 5 year warranty. Register within 30 days of purchase, and provide proof of purchase for any warranty actions."
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.
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
