I have built my first true gaming PC with a combination of 2nd hand & new parts & everything works fine until I play a high graphics game (eg. Battlefield 4, Far Cry 3, Starcraft II), after a while my PC would just black out & reboot.
At first I thought it was an overheating problem so I purchased a new case with extra fans & the problem seemed to be worse. I have run a remote system monitor & all the temperatures during games are a couple degrees below 60C when it shuts down so now I am beginning to suspect that it may be my PSU isn't sufficient enough for the job.
So is there anything I could do about it or should I just get a better PSU & if so what would be the best one recommended?

This is my current setup:

Motheboard: ASRock Z77 Extreme4
Processor: Intel Core i5-3350P CPU @ 3.10GHz
Memory (RAM): 16.0 GB DDR3 (4 x 4 GB)
Graphics: GIGABYTE NVIDIA GeForce GTX 770 OC 4GB GDDR5
PSU: CASECOM 600W ATX POWER SUPPLY 120MM FAN, 6 PIN VIDEO, DUAL 12V RAILS 28A & 22A
Hard Drives:-
Primary: Seagate Barracuda 1TB
7200RPM SATA 6Gbps 64MB Cache
Others:
Seagate Barracuda 1TB 7200RPM SATA 3Gbps 32MB Cache
Western Digital Caviar Green 2TB 5400RPM SATA 6Gbps 64MB Cache
Case: Sharkoon T28 Blue LED Gaming Case Front USB 3.0 ATX Mid Tower PC Chassis

Im not 100% sure but I think you might need a new PSU because your graphics card power requirements are 600W. So it will use most of the power so i would recommend you get a 750w-800w psu.

What is your budget for a new psu?

AMD and Nvidia state more than enough. They are afraid that you buy a really really lousy PSU that does't supply 600 watts when it states 600 watt on the box. Your build works fine on a decent 500-600 watt PSU. I've never heard of your PSu before and I suspect that it might be the cause o the problem. Your PSU may not be of high quality and it might be giving you power failures.

The Seasonic M12ii 620 watts would be good

Pretty low unfortunately, the graphics card & motherboard took a bit out of the funds & I bought the cheapest PSU at the last minute because I found out my old one was only 250W after I placed the order. If I need to I could hold off on the games until I can save enough for a new decent PSU, I figure that a month or 2 without games is better than frying the whole system & not having a working PC at all.

Thanks to everyone for the replies, I'll look into getting a decent 750w-800w PSU & hopefully I can get back into the PC gaming again without any more issues.
