Custom Build PC Crashing, suspected PSU or GPU

Before I get started I will post my specs here:
-Intel i7 4790k @ 3.60Ghz
-AMD Radeon R9 270x 2GB
-G.SKILL Ripjaws X Series 16GB
-ASRock H81M-HDS R2.0 LGA
-PSU UNKNOWN
-Cooler Master Hyper 212 EVO

My custom built, clearly designed for gaming, will crash mid-game, and given while it is only in gaming, has become more and more frequent lately. My first monitor, an HP 2511x will turn either blue or red, and have a shutter like design across the screen, while my smaller HP LV1911 at 720p just turns a plain white. Temperatures are not an issue at all, on my GPU I hardly go over 50 degrees Celsius and with the Hyper 212 paired with the 4790k, well, I never even see above 50 degrees either. When the PC crashes it just leaves an annoying buzzing sound and I am entirely locked out of my system, and it remains that way until I hard boot.

Now, I know, the PSU unknown probably made you massage your temples, however when I was building this PC the case and PSU were given to me, and basically I am educated on every aspect of building a computer except for selecting the right PSU. However there is standard information on the side of the PSU I can relay to this thread, and I would like to know if I need to purchase a new one due to voltage shortages or not.

VOLTAGE:
AC-Input: 115/230V~
MAX DC:
+3.3V +5V
OUTPUT:
22A 16A
130W

And then under the "combined power" tab it states 480W total, if a new PSU is required could I please have recommendations for slightly heavy gaming?

If it contributes to the troubleshoot my computer, when I turn it on after shutting off, will turn on and the fans will spin for a few seconds then it will turn off, back on, back off, then boot normally. If anything sounds like a power problem to this PC noob, it's that. I appreciate any and all help, and hopefully this will not end up burning a hole in my wallet.

A low quality power supply can kill every component it's connected to. First step, make sure you have a good one, what is the brand and model of the PSU? Is anything overclocked? If it is, you need to test the systm at stock speeds. Test your video card in another sytem and/or another card of similar power use in yours.

If the power supply is only rated for 130W that would definitely cause a crash. Personally I would under clock my GPU a bit, maybe 100 MHZ and run a stress test and see what happens. Unfortunately im not really sure how to test a PSU for output but with that low im kinda surprised it would even boot, but then again at idle they won't draw much power.
