Computer Lose Power Randomly

[Nicholas Hanshaw]

The computer I have is a gaming pc I built around a year ago.

Motherboard - ASUS AM3+ M5A 78L-M
CPU - AMD FX-8320
PSU - Corsair CX600
GPU - Gigabyte R9 270X
RAM - Kingston HyperX FURY 2x8GB
3 Kingston SSD's and a WD HDD

For a while now I've been having this issue where my computer just loses power like it was unplugged. No cycling or anything just off. When I start it back up it acts like nothing happens gets to desktop just fine no errors anything. I have no clue why all I can think of is PSU failing I know it's not the best but it's not a random company no one has ever heard of either... Yeah there is a bit of dust but not enough to worry me. Cable management looks like crap but nothing blocking air. I can't honestly think of what it would be. Any ideas.

I will update this with anything else I can think of as well as any new developments.

Corsair CX600 ...possible issue with the lower quality CX series

And the board has a poor power and thermal design , shouldn't be running a 125w CPU.
