Question PC Randomly turning "off"?

[XeroTR]

Every now and then (Pretty rarely), My monitor just loses signal, Keyboard and mouse lights turn off, and PC becomes unresponsive to case power buttons.
Specs just incase:
CPU: Ryzen 7 1700X
GPU: RX 580
RAM: 2x 8 GB F4-2133C15-8GFX
Mobo: Asus B350-F

Drive: Samsung 250 GB 970 Evo
PSU: Antec neo eco 520c

Get rid of that cr@p PSU.

"Some" branded PSUs are utter garbage.

1. What PSU is it? need to know if it's a good one or bad to determine if it's likely to be the PSU.

2. Are there any repeated precursors to the crash?

3. Are you running any overclocks?

4. How old is your pc?

5. Temps?

These should cover most info needed.

My guess is that you have a bad PSU.

Updated thread with a bit more info,

1. No, It happens at idle and under load.
2. No.
3. The mobo, cpu, gpu and ram were purchased in december of 2018.
4. Last time it happened, it was idling at somewhere around 30-40 C.

It would still be good to know the brand and model of the PSU, though.....and how old it actually is; because

The mobo, cpu, gpu and ram were purchased in december of 2018.

makes it sound like you re-used an old PSU.

I updated the thread with that a bit ago, It is the old PSU from when before I upgraded.
Which means I probably bought the PSU around 2013 or so.

Replace it. Period.

Select a 550W, "Tier-1" PSU from this reference:
