Pc shuts down whilst gaming

[Fontaiend]

Hi

I build my PC about 2 months ago and I wasn't experiencing problems until recently, my PC shuts down whilst gaming.
It happened about 2-4 times over the last few weeks but it keeps occurring more frequently every time. The temps on my CPU and GPU never go above 70 C so it isn't overheating.
Maybe a PSU problem?
Here's my part list:

MSI Z87-G41
Intel Core i5 4670K @ (4.2 Ghz 1.22V)
MSI GeForce GTX 760 (OC'd myself)
Crucial Ballistix Sport 2x 4Gb
Corsair CX500M

Here are my voltages from hwmonitor

I also downclocked my CPU to 4.0Ghz @ 1.150V

My PC restarts automatically after shutting down btw

"Over-voltage and over-power protection, under-voltage protection, and short circuit protection provide maximum safety to your critical system components" More than likely if your rig is sapping your power it could be doing it in order to protect your rig. I know many of the Corsair PSU's do this.

I heard Corsair made good quality but if the PSU is failing I'm not gonna be happy.

Anyway, are the voltages off or is there nothing to worry about?

The only thing I can think of is that you are not getting enough power. :\

Yeah but the weird thing is it started happening just recently and I'm almost 100% positive that 500W is plenty for my system
Could it be my graphics card failing or is it the PSU for sure, if so I'll RMA it probably

I have just now been able to find the power requirement for your GPU. The minimum is a 30A and 500W PSU. So since you have the minimum, it could be that reason. When did you start OC'ing your GPU? And are you OC'ing anything else besides your GPU?

Power requirements for graphics cards

 

[Fontaiend]

Yeah I OC'd my GPU aswell

 

[Nordein]

Yeah I OC'd my GPU aswell

If you are OC'ing other components besides your GPU then I would say your computer is going to need more power. That would be my only guess. Not sure why it is just now happening, but that seems to be it.

Could be the case but I'm still confused because of it not happening earlier, I didn't experience any problems since I OC'd Both my CPU and GPU until recently
I just reset my GPU to default clock speeds and I'm gonna test if it helps

 

[Nordein]

Okay well hopefully that helps.
