The PC might be restarting on its own, possibly due to a failing PSU or an incorrect BIOS setup.

Hello, perhaps you can assist me. This is my system:
Gigabyte GA990Fxa-UD5
FX8320e OC @ 4.4 Ghz
Vcore +0.125
LLC set to Very High
2 x 8GB DDR3 RAM
Power Supply: Corsair CX600M (refurbished)
Water Cooler AIO: DeepCool Captain 240 EX
Zotac AMP! Edition GTX 1060
400GB SATA SSD
2TB HDD
RGB light strips NZXT Hue+, I like shiny things
😛
Case: NZXT H440
I assembled this PC about six months ago. There were no major issues. From the start, when I power on the machine, all fans and LEDs activate, then after a second they shut off, followed by a few seconds before turning back on and finally booting up. That behavior was unusual to me, but since it didn’t cause any other problems, I didn’t investigate further.
I overclocked my CPU about two months ago. It was my first attempt, and I really enjoyed the process. I believe I achieved a stable overclock. I stress-tested it with Prime95 for over an hour, and everything performed well—temperatures stayed around 35°C during testing and reached 65°C after one hour. I also tested 1080p video encoding without any issues, and I’m quite satisfied with the performance.
Everything was fine until about 15 days ago... The PC started shutting off and turning on suddenly. Initially, it happened once every couple of days, but now it seems to occur roughly every hour.
I’m wondering if this is related to my PSU, since I’ve heard the Corsair CX series doesn’t have a great reputation... Or maybe there’s an issue with my overclock?
Is there a way to determine if the problem stems from the PSU? I wouldn’t want to buy a new one, install it, and then find out the issue persists.
We could discuss hypothetical situations all day long, to be honest.
If the overclock eliminates most of the issue, then your suggestion might be valid.
If it still stops completely, simply swap out the PSU.
Even now, if you wish, just change the PSU.
The overclock should still trigger an error, not just shut down. That’s usually a PSU problem.
I’m advising to test no overclock before spending money, since there’s still a small possibility.
Test without increasing speed. If the issue persists, it wasn't that. Consider getting a new PSU or reaching out for warranty support. If that resolves it, the problem was with the PSU.
The_Staplergun :
Eliminate the overclock. Try it again. If the problem persists, it wasn't that. Consider getting a new PSU or contacting support for warranty if possible. If that resolves it, the issue was likely the PSU. I'll try it now and see what happens. Also, could it be that once the problem disappears, the CPU still doesn't draw much voltage, making the issue less obvious?
On the side. A 600w supply seems sufficient for my setup? Was I thinking about purchasing a 600w unit because the PSU might be the cause, or should I opt for a 700 or even 750w one?

We could throw hypotheticals all day long to be honest.
If the overclock removes the large portion of the problem, then yes your idea could be right.
If it still shuts off, just replace the PSU.
Even now, if you want, just replace the PSU.
The overclock should still throw an error, not just turn off. That's generally a PSU error.
I'm saying test no overclock before dumping money, because there's still a slim chance.
Yes that's what i thought, since it doesn't show any error message or blue screen or anything i thought it was the PSU.
I removed the OC yesterday afternoon. I haven't used my pc much since then. But i haven't had any sudden restarts since.
Still, i am just not confident on PSU, and believe every time something fishy goes on my pc it's becouse of the crappy PSU. So, for peace of mind, and as an starting block for the upgrade i plan to do in about 10 months (switching to rysen or kaby lake). I just bought a 650w EVGA SuperNova P2 on amazon, it should arrive next week. I will try my OC again when i have the new PSU installed.
Sounds good. I'm not sure about that specific PSU yet, but I'll keep an eye on it and let you know as soon as it arrives.
The_Staplergun :
Looks good, just wanted to check in about that specific PSU. Let me know when it arrives.
Sorry for the delayed message, I received the new PSU and the problem with the CPU overclocking at 4.4 Ghz continued, so I lowered the overclock to 4.3 Ghz and it stopped.
I'm still glad I bought a quality PSU because before any issues, I always thought the refurbished CX600M might be the cause. Now that I have the EVGA 650 P2, I know I have a top-tier PSU and don't worry about that now.
I'm thinking about upgrading to Ryzen later this year, so this new PSU is a solid foundation for the upcoming upgrade.
