Your power supply has four rails. Try reworking your wiring to draw power off of separate rails and give it another go.

but i still would not do it

with the off chance of the psu blowing up and taking some components with it i would not advise doing this.

lol, and risk blowing ruining the rest of his components? thats sounds risky, and most are not technical enough to be able to do that know that they did it correctly with out screwups.


If I had to guess the wattage is fine, just not enough amps on the 12v. Get a high current 700 watt PSU, should be good to go.

That's major overkill for a system with one 6990 in it. Any quality 650W to 750W power supply will be enough.

Here are some now (I tried to keep the price relatively close or lower to the 900W High Current Gamer you're looking at):

Out of all of these, my choice is the 750W Antec TruePower New because it's basically just as good as the HX750, except it's not quite as modular (it's only partially modular). The rest are not modular.

These are still overkill because AMD recommends a 750W peak-rated power supply to handle a system with one 6990 in it, and these are all continuous-rated units (they have a greater capacity than any 750W peak-rated unit while simultaneously being able to deliver power that is much cleaner and much more stable).

The 900 was recommended to me by the dude at the local comp supply. He's the one who helped troubleshoot my problem. the antec 750 is very nice.

Here's a little bit more information on the 750W Antec TruePower New:

Combined the TP3 units with the SeaSonic M12D platform? Whatever they did, the result was pure awesomesauce on a bun, resulting in a superb 750W power supply that performs comparably to then reigning champion Corsair HX750, for the significantly lower price of the TX750. The voltage stability is excellent and the ripple suppression is too! And it's partially modular? Holy crap, this is amazing! And the 550W version can be had for a mere $65 AMIR at Newegg at time of writing. GO. BUY NOW. Seriously, that's the best PSU bang for the buck I've ever seen (Well, except for the SeaSonic M12D 850W for $140. But that only lasted, like, two days before they sold out so it doesn't really count. Wish I'd picked up on it, though).

The only thing dragging this line down is the partial modularity, and... Both 4+4 and 8-pin mobo connectors? You only need one of those cables on a 750W PSU, any system that needs both won't run on a 750W unit in all liklihood. But otherwise they're superb! They make the Corsair TX series obsolete, and give the HX series a run for its money.

Ive got my new PSU. I went with an antec HCG-900. Plenty of power for future upgrades.

I just booted it up and got my overclock in. Im running stability tests now.
