Computer restarting Power supply issue?

[Bazzards]

Hi Guys

I have been having issues with my pc restarting. I can run heaven benchmark without issue, however if i play any game, Cod ghosts/BF4/dying for example then the pc randomly restarts.

My top gpu reaches a temp of about 80c with fans at 80% however, if i run in non sli mode i do not have any issues.

When gaming the wattage meter on the power cord shows that I am pulling 900 watts, can this be right for my system? I am running a couple of 780's with a 4790k all at stock. I also have 1 ssd and 3 hard drives an aio cooler and 5 case fans.

I have checked all cables and all are secure. Could this be a power suppy issue?

Cheers

900W!!!

I thought it didnt look right. I am not sure how accurate the power meter reading is though. At desktop it says i am pulling 170 watts.

I'm not sure that's right, unless you have some insane overclocks. I've got a 850w running 4790k @ 4.7 and 2x GTX Titans and I'm pretty sure I'm nowhere near 850w let alone 900!!

I have just run heaven benchmark, 1 card 510 watts score 1450, 2 cards 840 watts score 2750. Should I be allowing for for the inefficiency of the power supply?

How old is the PSU?

Purchased July last year.

That can't be right surely? I only have a single 780 but the most I can make my system pull is 452w and only by running Furmark and IBT both at the same time. Have you updated the bios on your motherboard as early versions on Z97 overvolt the cpu?

My CPU is at 1.25 volts according to CPU z. Will che k for BIOS.

I have updated to the latest bios and set the cpu at 1.24 volts. I dont think this is the issue though. Think I may need to RMA power supply.

Certainly doesn't sound right
