I just bought a BFG 7900 GT OC with 256MB PCI-E.
I installed it into my system:
AMD 64 3200+ OC'D to 2200 MHZ
ASUS A8VE-SE
1 GIG OCZ Ram DDR
100GB SATA Maxtor
DVD-RW
Soundblaster Audigy 2
CASE: Antec TX1050B with True Power 500W at max 35Amps, my voltages are ok at all times I could test it.
So....i installed the card...plugged in 2 molex connectors to the card...and plugged the power supply back, turned on th PSU...and pressed power...nothing.
So... I tried the card without the molex connectors...no power...I tried it with my old video card (Asus EN6600) no power...hmmm did I fry my motherboard?
So...I tried to connect the BFG molexes to a new line straight to the PSU...nothing...
I tried to disconnect and reconnect all powered items...no power...
I tried to disconnect all my fans (not the CPU) and...the system "BURPED" into life...on, off, on, off...I could hear the BFG's fan turning on and off etc. etc. like a turbine trying to start.
After lots and lots of problems and tech support from BFG (they were real nice), I saw some real real strange bnehaviours.
i) The PC rebooted if I tried to enter the bios, many times.
ii)The PC booted into windows just fine without the fans.
iii)If i tried to add a fan (out of my 5 extra fans) and any that I add, the system does not run.
I want to know why my PC witha 500W PSU will not support a BFG 7900GT OC, and a single extra fan...WHY!?
