Bad XFX R7970?

[blastborn]

Just finished my first build in awhile:
Asus M5A99FX PRO R2.0 140Wmax
AMD FX 8350 125W
XFX Radeon HD 7970 ddr5 250Wmax
Kingstone Red 8gb Ram module
Samsung 840 series SSD .071W
Toshiba 1TB HDD 6.5Wmax
Thermaltake 750 Watt bronze

I put all the newest drivers on for the motherboard and GPU and everything works great...until I put a load on the GPU (gaming/windows exp. index) and it shuts off (one long beep followed by 3 short beeps) indicating VGA test failure or no VGA card found.

Im running 2 8 pin connectors from my PCU. Going into the GPU, one is a 6 pin and the other and 8.

Temps are all normal. Total system wattage is well under 600.

So what do you guys think? Bad card? Bad motherboard slot? Bad Power Supply?

The issue sounds power related to me. Are you sure you have the proper connectors hooked up?

Is anything overclocked? The 8350 can easily draw well over 200 watts overclocked. The 7970 is also a power beast once you overvolt and overclock it.

I think SB is spot on.

Thermaltake 750 Watt bronze :thumbsdown:

Just had one fail on me -- 2 weeks and it's dead

Update:

Hooked it into a different motherboard slot and got the same result. Tried powering the card with a friend's nice 1000watt power supply and got the same effect.

I'm RMAing the thing back to tiger direct.

I've been searching the interwebs while awaiting the new r7970 and I'm nervous that I ran the power weird. I ran 2 8pin connectors out of the PSU. On the card end I used the 6+2 fitting to fill the 8 pin hole and another 6+2 fitting (with the extra 2 pins not plugged in) to fill the 6 pin hole. Was I causing an overload at my PSU?

I don't know any alternate ways of doing that.
