Hi. I was just wondering if this 300W would juice a 9800GT Eco (uses less then 70W's) along side a Q8200 and 4GB DDR2 (2x2GB,) The motherboard in question is a Gigabyte G31.

I'm building a custom case for a friend, he wants it to be the same size as the Xbox 360, so far everythings in apart from a custom PSU. There are a few, but my concern is if it will power it or not. Someone suggested in another thread that my 305W Dell PSU would be fine with this GPU...

Any ideas?

No. At 9A, the 12v-rail will explode.

9 amps on the 12V is weak, very weak. I'd say you'll have better luck with a 4670.

Even though the Eco doesn't need a power connector you'll be cutting it close.

Try it out if you want, run CRYSIS or a very intense game for 2-3 hours or more, then try 3D Mark vantage for the same amount of time, if it passes then it'll probably be safe.
