Is my PSU going bad?

[Soulliight]

Hey guys and thanks in advanced for taking the time to look at my post.

Just started today that when I'm gaming my PC will immediately restart. At one point it didn't turn on and I took it apart and cleaned it and plugged it into a new outlet which it did turn on but when I game I still have the problem.

My Build:
MSI B350 Gaming Pro Motherboard
Ryzen 5 1600 3.6 OC@1.24v
RX 580 8G
G.Skill Ripjaws V Series 3200 @2633
EVGA 600w 80+ Bronze PSU
WD Green 500G 7200 HDD
Kingston 240G SSD

Peak Temps:
CPU @ 50C (Never goes over this)
GPU @ 70C (Never goes over this, the fan turns on @70C otherwise its off)

Thanks again!
-David

In most cases, reboots during gaming are caused by 2 issues:
1. CPU/GPU overheating
2. Low quality PSU that fails to deliver enough power to your GPU.

Since your temps are in normal range, it's most likely that your mediocre quality (Tier three) PSU is the culprit,

For a new PSU, aim towards any good quality (Tier one) unit, preferably great quality (Tier one) unit.
Anything from Seasonic lineup will do just fine, e.g G-650,

Im looking at a evga supernova g2 550w psu and it has a jhonnyguru rating of a perfect 10.
I choose 550w because evga power meter on thier website said I only need 550w however I wanted to run it past you to see what you think. Is that enough wattage for what I have?

EVGA SuperNova G2 is great quality PSU that uses Super Flower's platform. Though, your RX 580 is power hungry GPU and it can consume up to 225W. 550W EVGA PSU should do i you don't OC your CPU or GPU. But if you plan to do OC, then i'll be more comfortable with 600W range PSU, e.g SuperNova G2 650W,
