My PC shuts down randomly, while im playing games, watching videos, or just browing internet. It's happening since i bought GTX 560 videocard.
I think that my PSU i failing, because when i removed my CD-ROM, it's shutting down less frequent.
Windows log:

No BSODs
My PSU specs: max 500 wats, 12v rail - 30 Amps.

It's my PSU or GPU failing?

Yes seeing as it's underpowered with a low quality power supply. It's rated at 500w, but in actuality it maybe pushes 450w. Low quality power supplies never push their rated wattage.

what they said ^

A psu can cause all sorts of problems from what look like software problems to hardware problems especially when low quality and especially when underpowered.

do not buy any old 750w power supply buy quality like the one mentioned. A psu is the most important part of your computer, there is no point in having a good system with a good graphics card and a crap psu it will only lead to trouble.

no an ATX power supply is what you need they are all the same size. You should go for the one linked above.

seasonic, xfx and xorsair (not gs or cs) power supplies are what you need and you need atleast 750w

Coolermaster are hit and miss. Stick with the ones greenbrucelee suggested and you'll have a good quality PSU. XFX are the best bang for the buck in my opinion and carry a 5 year warranty.

"Some" CoolerMaster are OK. Stay with SeaSonic-XFX-Corsair (not the CX-GS-M Series) for guaranteed quality and reliability.
