Is my PSU the problem?

Hi, when I try to run games at the highest quality, my system will crash. I think it is because I went too cheap on the PSU. I have made sure all of my drivers are up to date, but I am still experiencing crashing. Here are my specs:

Diablotek UL Series PSUL775 775W ATX 12V v2.31 SLI Ready CrossFire Ready Power Supply
BIOSTAR TZ77XE3 LGA 1155 Intel Z77 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard with UEFI BIOS
EVGA 02G-P4-2678-KR GeForce GTX 670 FTW 2GB 256-bit GDDR5 PCI Express 3.0 x16 HDCP Ready SLI Support Video Card
G.SKILL Ares Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-1600C9D-8GAB
Intel Core i5-3570K Ivy Bridge 3.4GHz (3.8GHz Turbo) LGA 1155 77W Quad-Core Desktop Processor Intel HD Graphics 4000 BX80637I53570K

After I bought the parts and assembled my pc played a few games and had it crash in a few, I did some research and found out that Diablotek sucks, but is that the cause of my issues? Is there something I could try to narrow down the problem?

Try a different PSU? Other than that there's no definite way to tell.
Also, if there's a complete hardware shutdown, then the PSU is suspect.

It is not a complete hardware shutdown, the graphics freeze and the sound is just a constant buzz, and the only thing I can do is reset my computer.

Then it seems like the Graphics card. Either its faulty, or its not getting enough power.
So yeah, you need to try a different PSU to completely rule out the PSU.
Or try your graphics card on another PC.

Alright, thanks for the help. I will try a different psu to see if that helps.

uuh.... diablotek is a REALLY bad PSU maker, i am 99% sure that the problem is the PSU. replace it with something from Seasonic, XFX, Antec, corsair, PCP&C or enermax.

Just a quick update. I had an old ocz psu and I tried that. It is only 500w with two 12v rails at 18 amps a piece, and it ran longer before problems started to arise. So that one isn't good enough either, but at least I know where the problem lies. Thanks for all of your help!
