So today I'm minding my own business when all of a sudden smoke comes out of the PC along with the fun smell of toxic fumes.

Looks like just the power supply unit was the only casualty.

Problem is I can't find the same unit anywhere. I'd love a suggestion. Probably going to replace with a laptop in a few weeks, but need something I can pick up a local compusa to get me back to work tomorrow!

Here WAS my build:


1 x COOLER MASTER RC-690-KKN1-GP Black SECC/ ABS ATX Mid Tower Computer Case


1 x APEVIA CF12SL-UBL 120mm Blue LED Case Fan


1 x XFX HD-577X-ZNFC Radeon HD 5770 1GB 128-bit DDR5 PCI Express 2.0 x16 HDCP Ready CrossFireX Support Video Card

1 x OCZ StealthXStream OCZ700SXS 700W ATX12V / EPS12V SLI Ready CrossFire Ready Active PFC Power Supply


1 x GIGABYTE GA-MA790GPT-UD3H AM3 AMD 790GX HDMI ATX AMD Motherboard

Ohh and I should mention I did add on another HD a few weeks ago and another 8 gigs of ram since it was on sale with something I bought for my wives p.c. - could I be overloading the current one?

Honestly not sure. Either way I need to fix it before I'd get it back under warranty...

Wattage you'd recommend?

I won't be adding a second video card to the machine ever so do I need a xfire ready PS to go with the video card?

a good 550w psu should be plenty for that set up

corsair,seasonic etc--quality makers

no it doesnt have to be xfire/sli certified

and adding ram and a hard drive wouldnt have increased the power draw by much

maybe 5 watts per ram module and say 25w to 30w for a hard drive i would guess
