Computer restarts under heavy CPU load...

[Dayzed]

My hackintosh works great 99% of the time until I started using After Effects. While rendering out projects everything seems fine for a minute or 2 then out of the blue the computer will just turn off then restart itself. I have a Corsair 650w PSU, 32gb of Ram, 3770k(stock clock speed), 3 hdd, GTX 660 TI and the Z77X-UP5-TH motherboard. I believe that the PSU is well within its capabilities. So my question is...

Do you think the power supply is too small or maybe faulty?

I have no issues with it during regular use.

Thankx in advance

I would try increasing the voltages slowly in the bios.
