I brought home a BFG 7800 GS OC AGP card.

I have an ATX 500watt power supply

Not exactly high end, but not a slouch either.

I had it powering the stuff in my sig plus 2 hard drives and 1 cdrw and 1 dvd rom drive. Plus 3 case fans.

The box says that a 400 watt psu is needed, but I don't know what's going on. I deleted the old drivers (and used driver cleaner) and powered off. Exchanged cards and powered on. I get to the black post screen, but I never get to the Windows loading screen.

Is my PSU not big enough or is the card faulty?

On a side note, does the PCIE equivalent usually take less power?

you will be fine, I have my BFG 7800GS OC running in a system with an ANTEC SP350W psu with only 16a on the +12v, it runs 100% stable 24/7.

the specs of the system that I have it in are as follows

P4 3.0@3.4ghz skt478 (prescott)
GA-SINXP1394 rev 3.0 (SIS655TX)
1Gb DDR400 (2x 512mb)
2x WD1200JB in Raid 0 (240gb)
LG 16X DVD-ROM
LG 16X DVD-RW


The 7 series GF cards aren't power hungry monsters, have you tried a clean install?

I don't want to do a clean install.

Pain in the butt. This card should've worked anyway.

Sounds like the card is faulty.

WTH is going on?


This new card won't work either. I just can't believe I have to do a fresh install of XP.


Any suggestions?



Maybe my power can't power this thing. Anybody?
