Ok so i've built a new PC here's the breakdown

MOBO - ASUS P5NSLI
Graphics Card - EVGA GeForce 7600 GT
CPU - Core 2 duo 6300
OCZ 2x512 DDR2
HD - 160gb Maxtor (already was using on other pc)
Power Supply - Coomax 400W

so here's what happened. put everything together plugged it in. everything seemed ok, hard drive spun up temp steady a little below 30C

then i brought it into my office plugged in the monitor and when i turned on the pc heard a loud POP sound a bright light around the video card area.

After that the Graphics card wouldn't work and the hard drive would not spin up unless it was only plugged to the power supply..tried other HD's and Graphics cards with no luck.
I've RMA'd back the video card and the MOBO for replacements (and upgrading the graphics card to XFX 7600 GT) . my question. Is it the MOBO that's likely fried or the Graphics card or both?
and the BIG question. is there a high chance that the CPU is cooked as well? unable to test it now as i don't have any other compatible MOBO's for the time being. thoughts?
also is here any easy way to screw up my connections to the MOBO that may have caused this?

hello:


your PSU is most likely the root of your evil!

Coolmax power supply units are very low powered and at only 400 watts that baby has gotta be gassed to the floor board.


I highly suggest you look for the Antec Trio TP-3 650 watt PSU they are a squeak over $100.00 these are first class units!

hope it didnt fry too much other stuff, this is when cheap and small PSU's really hurt the build and the wallet :mad: \


here is a classic example of a low quality 480 watt unit that would trip the protection at 277 watts !!
