What's the problem with this graphics card? Any ideas?

Hey guys, my mate's put his i7 build together from OC today, except his graphics card shows a lack of power obtained. The system is as follows, and he gets three red lights on it:

Intel Core i7 940 2.93GHz Socket 1366 8MB Cache Retail Boxed Processor
Gigabyte GA-EX58-UD3R iX58 Socket 1366 7.1 Channel Audio ATX Motherboard
Hi-Power Black 800W 14cm Blue LED Fan PSU - 20+4pin 4x SATA 4x PCI-E
XFX ATI Radeon HD 4870 X2 2048MB GDDR5 TV-Out/Dual DVI/HDMI (PCI-Express) - Retail £299.99 1 £299.99
OCZ Gold 6GB (3x2GB) DDR3 PC3-10666C9 Low-Voltage Triple Channel (OCZ3G1333LV

Any ideas what this might be ?

Do you have the GFX card connected to the PSU? It's normally a 6 pin or 8 pin connector.

Never heard of that PSU manufacturer before, plus OcUK don't sell them so I don't think your mate got it from here.

But yes, sounds like the PSU is to blame, although the GPU could be a also be a duffer - have you tried the card in another machine?

Don't you need like 30-40A on the 12V Rail to run a 4870X2? The Hi-Power only puts out 20A max on each 12V rail. So make sure the power to the card is coming from separate cables
