Triple monitor power problem

ive just gone SLI with my 660 ti and i have a 3 way monitor surround setup. But my computer just shut off as if someone has pulled the power plug out. But if i go SLI with just one monitor it doesnt. Is this a PSU problem or maybe a bois upgrade issue?

The extra work might be making the GPUs draw more power from the PSU with the soround display, and 600W might not be cutting it.gp19

I thought the same thing but it runs fine with just 1 monitor. soon as i put the 3 on it cuts out, but not all games has this effect. Ive just been playing dishonored and it didnt crash. But with crysis 3 and mechwarrior online it does. Same with kombuster. Thats why i mentioned BIOS update?

run the power supply test, will load your cpu and gpus to 100%

it basically runs linpack and furmark at the same time

600 watts won't be enough to power that while running 3 monitors. Your 2 GPUs will be drawing max power while running all 3 in game. You should get a 1000 watt PSU. That will slove your issues.

Even with just 1 monitor and SLI enabled, you won't max those GPUs out. They draw the most when they are outputting to all monitors while hitting near 100%. Very few games can max SLI GPUs at 100% and they are pushed even further when outputting more video.

How does a 600w att powersupply have 4x 6 pin connectors ? (each 660ti needs 2). Please dont' tell me your running two of the 6pins off molex adapters.....

Do you think 750W would be enough? and do u need a dual rail psu?

Would these psu specs be enough to power my rig

22 amps on the 12 volt rail is roughly 265 watt.  Your cards have a max power consumption of around 130 watts, that's 260 watts total. To stay on the safe side, look for a PSU with at least 30 to 35 amps on the 12-volt rail(s).

Antec High Current Pro 750watt

Antec High Current Gamer 750watt

Corsair Enthusiast Series TX 750W

this one any good

and it comes with

Now am i rite in saying that each of the two PCIe cables has two sets of 6+2 pins connectors?

That one would do fine, though it has only 4 SATA connectors, which is a touch thin.  Of course, it still leaves room for one ROM and 3 hard drives... depending on if you use only SAATA devices...

But the PSU is okay, both qua watt as amps.

yeah ive only got 1 ROM and 1 HHD
