Hello there, I am very confused rn. I have a PC, with a Corsair CV650(650w). Ryzen 7 3600x, and a gtx 1650S. My PC works fine all days of a week, I use it for gaming, work, rendering... But on Sundays, the pc suddenly turn off because a PSU error power error. It's strange bc it only happens on Sundays I had this problem for two weeks from now.
Anyone has any clue? Should I change my PSU?

Pd: Srry for my English

Sounds like your PSU just needs a day off. ;)

Seriously though, is anything different on Sundays? Some appliance or device running that normally is off?

Have you tried a different electrical outlet?

Nope, the same devices running, I don't think that needs a day off, it shuts down even on ideal with all the programs closes, yep I tried other electrical outlet, the same result.

try change your system time on bios and see if happens again, then if its a software problem you know its in bios
I was going to try that out but it won't stay on enough time to enter the bios, I think I still have warranty, may I change the PSU? Btw I'm going to whait I till Monday .

The Mobo seems to still having power after the pc shuts off(the power button of the case is on as well of the keyboard lights) I'll try to do a system reboot to see if the problem is caused by the os or a virus if it isn't I'll have to change the mobo, tysm for your time and answers btw

thats weird, try clearing the CMOS maybe its got some settings saved. i did that when my power switch timing wasnt working correctly almost feels like the power switch settings are save by the CMOS battery

I am wondering if there is an issue with the physical power button. Disconnect the power button connector from the motherboard front panel header.

Then, with a screwdriver, just touch the two pins briefly. This will close the circuit, like the power button does, and will start the system. You don't hold the connection long, just a touch.

Just tried it, the physical button and the pins work fine.

Any way you can borrow an UPS? maybe your area suffers from a minor brown out? and only on Sundays due to some switching problem at a sub station, worth a try though.
