XFX 9800GT GPU & 780i XFX MB... 8pin power connector issue?

Hi everyone this is my first post:
I have a XFX 9800GT video card and 780i XFX motherboard, 4 gigs of SLI-ready OCZ memory, 480 Power supply..running XP Pro 64bit...Intel Duo Core 3.0 CPU.

I also have an Orion 585 psu I can use.. but I heard its terrible.

The 780i XFX motherboard has a 24pin ATX power connector and a 8 pin cpu ATX power connector.

When I had nothing installed on the 8pin connector... the computer would not post even to bios.

Since my power supply does not have a 8 pin power connector for the cpu... I installed the 4pin video power connector into that 8pin since my video card does not require that wire.
After installing it.. it posted.. so I got to bios.. did all my settings and installed XP Pro 64bit OS.

After upgrading all drivers on everything, including flashing the bios.
The system appears stable.... however....

In the game Battlefield2...
I am getting lock-outs, and graphics going crazy in the game after 10 minutes. Not good.

I purchased a molex to EPS12v (8pin) to plug into the CPU power connector.

Do you think that will work?

Or should I just purchase a PSU with the EPS12v 8pin wire already. Money is tight.. I just spent $500+ to get me to here.

  1. ok.. so I get an MOLEX to EPS12V 8pin adaptor... and there was no difference... Battlefield 2 still looked terrible! I totally cleared out those nividia display drivers in safemode.. and reinstalled with the latest and greatest... still BF2 started to fail...even worse now with a strong lock up for a brief 4 seconds. I have a new PSU that has a dedicated 8pin EPS12V power, Actually its a bit overkill I think:

    Athena Power AP-P4ATX55FEC Continuous 550W @ 40°C EPS12V Ver. 2.91 SLI Ready CrossFire Ready Nickel Coating PS2 ATX v2.2/ EPS12V Power Supply - OEM

    Hopefully this will resolve this issue... or... its the video card?

    I am also running 4 gigs of OCZ NVIDIA SLI-Ready Edition 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model OCZ2N800SRC44GK

    Now that memory was recommended to me by Newegg... I hope to post a good result tomorrow afternoon!
