Question 650W PSU not enough for specs?

[BlazHUN1]

Hi guys! I've recently upgraded my cpu from Ryzen 5 3600x to Ryzen 7 5800x, and after 2 months of use my PC started encountering random shutdowns, mainly when firing up games. My build is Mobo: Gigabyte B550M Aorus Elite, Ryzen 7 5800x, Gigabyte RX 5700 XT, 2x8 GB TridentZ 3600mhz, 2 Sata3 Samsung SSD-s with an AIO and 3 fans, and the PSU is a CoolerMaster 650W MWE Gold. I've been using this setup for mining however I don't think its the GPU, for me it sounds more of a PSU problem. Also when it shuts down I can only turn it on with the reboot button not the turn on button. If PSU change would be the case what model would you suggest?

Thank you for the replies!

Start here:

Use the calculators to size the PSU - at least to determine some consensus wattage value.

If possible, test the GPU in another known working computer. Determine if the random shutdowns follow the GPU.

And if you have a multi-meter and know how to use it (or know someone who does) you can test the PSU to some extent.

Not a full test because the PSU is not under load (e.g., bit-mining) but any voltages out of tolerance make the PSU suspect.

It should be plenty of power for your specs , but the quality of the PSU is poor.

Reviews sound like it should be replaced:

This would be a decent replacement.

Thank you! I might upgrade to a 750W as I plan to replace GPU with 6800 XT. Yeah when I built the PC I wasn't really careful when choosing PSU and kinda skipped the holy grail of don't skimp out on PSU. Before I might give a shot on a multi meter to determine the power draw from the wall.

Thanks, I might try the multi-meter part first before spending on more expensive parts.

The PSU runs ad protects your setup. And it's most likely your issue. Upgrade when it's possible.
