hello

i've attemped to run two psus at once but am having issues, could be for a number of reasons.

I noticed i was overheating a lot in games, more to the point actually crashing in dx11 games [battlefield 3]

system spec

ASrock 890fxdeluxe3
phenomII x6 1090t black edition
8gb 1033mhz ddr3 RAM
2x HIS ATI Radeon 6970s [flashed 6950s. original problem was not fixed by unflashing]

Power Supplies - 1 650w OCZ Battle, was upgraded previously because of heat issues - this is currently plugged into the motherboard, hard drive and cd drive.

1 850w PSU [was previously running the entire system yesterday before dual psu setup, it should be working], i think it is an Overclockers one, I was a noob and took the pc to a local pc shop when i upgraded, this is the first time i've replaced one myself :) - this is plugged into the two crossfired cards, and jumped with a wire cut from a molex cable.

The jumped PSU starts when the PC is turned off but when i turn my PC on everything runs normally for about 4 seconds until the jumped PSU turns off [or at least it's fan stops spinning.
The graphics cards make no beeping noises like they are underpowered, and the fans on the cards move slowly. But the screen receives no input.

If anyone could give me some assistance on Dual PSU setups or why my PC was crashing in the first place i would be incredibly grateful, i really am running out of ideas now.
 
My arguement about retailers selling crap psu's is justified by people like you who build a high end rig and then try to save money by skimping on the psu.

going a bit far there. it was my first build and i wasn't sure what to get, i ended up with the 650 watts one. Keep in mind at the time i wasn't confident enough to even put together the pc myself. It turned out the pc cut out after an hour on games so i took it to a local pc repair place, not a big retailer, and they put in the 850watt psu but i still have the same problem with dx11 games - i don't think it's the powersupply, i think it's cooling.

I put back the 850w PSU and ordered a custom CPU cooler and will take it from there.
