Well i bought an entire new PC, well, all the parts and put them together. However after installing everything correctly (i think) my 4870 is not getting power, so no image. i have the 2 connectors plugged into the card but somehow its not delivering any power. Asus P5N-D mobo Intel® Core™ 2 Quad Q6600 Corsair CMPSU-550VX PSU Club 3D HD4870 OC 4x 1GB of GeiL DDR-800 any help please?

Apparently you didn't benchtest your hardware before installing it in the case? "If my answers frighten you then you should cease asking scary questions" - Jules Winnfield (Samuel L. Jackson) in Pulp Fiction

A common mistake made when putting together a new machine is putting motherboard mounting studs in a place where there isn't a hole in the motherboard. This can cause a short circuit. Remove the motherboard and do a benchtest. How to do a benchtest: http://www.techsupportforum.com/har...

alright took it all apart.. did the benchtest like you specified (website) i connect the power switch and my CPU-fan kicks in, however my GPU-fan stays as dead as a cow. is my last option to just send the card back and ask for a new one?

Can you give more specs on the psu, such as amps on the +12v rail and so on ? It's possible that it's not sufficient to support the HD4870.

well i can tell you it is sufficient because it is 1) recommended by jam, no offense 2) in the qualified list on the ati/amd site 3) 41Amps on the 12V rail so im going to return the d*mn thing then...

No offense taken. I was just asking about the psu.
