PC Shutting off.

[Hollow021]

So I have this problem that I don't even know what causes it, so I didn't know where to post about it. But it has something to do with the psu I suppose. So I used to have this problem when I had my fx-6100 with stock fan and it would get hot like 62c so I thought the temp is the cause of it. I just got a fx-6300 from my friend and he had a closed loop water cooler so I got that too. I was playing Bf4 and it did it again but I was monitoring the temp too. It was running at 40c. + I'm overclocking it to 4.3Ghz at 1.38v. And something else, I read some overclocking guides online about fx-6300 and most of them said  I need 1.4v for my vcore but I can't do that on mine because when I do, it just gives me a black screen and nothing happens so I have to reset the bios manually with cmos battery. Not sure if it's my motherboard or my psu. my psu is some Turbolink 500w.

shoddy PSU

 

actually it could be the PSU or not. Typically the system will suddenly quit but it seems you have a hardware hang of sorts. 

replace that PSU anyway though

Is your GPU stock?

If you mean this one http://www.apevia.com/ProductsInfo.asp?KEY=ATX-CW500W its time to get a new PSU.

It's not. It's a HD 7790 1GB from asus and I'm not overclocking it but using Afterburner to have the fan running faster on some temps.

It's not that one. I'll send a pic.

And when it shuts down, my power button LED (green one) blinks.

It's not even a 500W psu. Rather a 400W if we just count the rails and I'm pretty sure this PSU isnt capable of delivering 400W anyways.

A PC shutting down is usually due to the PSU; a safety protection OCP kicking in complety removing the power.

How is it not 500w? It says 500w on it D:

The PSU is cheap but it might just be the overclock did you friend achieve it stable? otherwise its probably one of three things: 1.CPU isn't able to hold the OC 2.Motherboard can't handle the OC 3. The PSU isn't providing solid and stable enough power.

How is it not 500w? It says 500w on it D:

 

The majority of the power draw today comes from the +12v rail, in which certain PSU designs (those a DC-DC VRM) are capable outputting it full wattage of it, while other more basic PSU but modern would have the +12v occupied most of it.

 

A power supply that doesn't give the actual combined rating as well as tell us it is rated a peak load or continuously, often an indicator of someone got something to hide. You have two +12v rail rated at 16A and 18A. You would assumed that it has 34A on the +12v (408w); however, the rating are not additive. All that rating tells you is that you could load up that specific rail up to it, but not necessary at the same time, as the actual 12v capability is actually lower which the unit didn't provide.

 

Also, the -5v rail had been removed from ATX specification in 2003, and you are seeing it on your PSU. This is also an indicator that your PSU is based on an old, outdated design.

 

There are power supplies out there that are rated at 600w+ load and failed to output half of it safely. In actually, there was this particular ~600w unit that failed and violated ATX specification even at 100w load! Just because it is rated as something, doesn't mean it true.
