My PSU blew up...help!

Hi,

I have installed a Radeon HD2600 and a new 450W PSU. It lasted maybe a couple of hours, then PC powers down. After a while fizz, flash and wallop so I quickly take out the kettle plug. I now have the old PSU and the old card in. I hope the HD card is not screwed and still works.

Can you tell me the likely cause (the PSU was quite cheap, if that is it you learn your lesson I suppose) and a PSU (450W-500W) I can buy that will last more than 2 hours? I dont have that many components to run, just the HD card which has a four-pin molex like a floppies.

Hope you are able to help, these are the PSU's specs:

PowerX2: Standard Edition Power Supply

Output: 3.3/26 | 5/30| 12/17| -12/08| -5/03| 5VSB/1.50|
Input: 230/4amp

you find 17a on the 12v on generic 300w PSU

get a 400w+ from corsair, enermax, silverstone, seasonic, or antec

ocz and xigmatek have budget friendly units also.


decent - $40 + $10 mail in rebate

Do you think the card would have been damaged? How likely is it?

Also do you have a UK link for the Antec, I'd rather paypal it perhaps I'll look on E-bay. I am running two HDD, DVD-RW/CD, An audigy drive bay powered by floppy molex (I need 2 one for the card), Pentium 4 3 Ghz...nothing particularly strenuous so I assume the earthwatts should do?

no clue about the card, you need to test it out.

the antec will be more then enough

thanks for the help mate, its done. lets hope for the best. Is there a way of checking the card physically? (i.e like in the case of leaking or bloated capacitors)

well you can check it visually for signs of damaged but you really need to just boot up a PC and see what happens to be sure.

Went for the antec on scan, if it blows up again I'll blame you guys (kidding obviously)

I'm running on the new psu but the old card. I insert the HD2600, the system gets to the windows screen then, after having loaded, it reboots. I can boot in safe mode, and the hardware model shows in 'device manager' but I cannot install drivers.

I assume the card is fried, is that a fair assumption? If it was fried I would have thought the system would not boot up at all, or with a beep, but it does depend on which part of the card short-circuited.

This is absolutely true! You never try to save from the PSU!

yeah looks like it...you can always try to RMA as a dud ;)

Which card would you reccommend that is better than the HD2600 and would be fine with this PSU?

your budget? your monitor resolution? are you in the USA, Canada, UK?
December 3, 2010 8:58:16 PM

I'm in the UK. I was thinking the HD3650 was pretty good, something within that price range but probably second hand/OEM (about 30-40 quid)

Forgot to mention it is for an AGP 8X slot, while its a good card (the core/memory clock speeds, DDR3 etc..) it goes up to 80 quid so it might be a bit of a hit. thanks for chasing this thread...

yeah then an ATI 3850 AGP card is a good choice
