Question PC Lockup / Gaming

[Falcon6]

PC recently locks up while intense gaming, I think I narrowed it down to the power supply, "power usage" "processes" using Task Manager states "very high" for the particular game I am playing, although I would think I have plenty of power to go around? I can't say for sure if it started happening when I purchased my RX 580 awhile back, but it's very possible. Below are my specs. Thoughts? Thanks.

Mobo: Z170A SLI Plus
CPU: i7-6700K 4.00GHz
Memory: Kingston HyperX FURY Black 16GB 2133MHz DDR4 (x2 8GB)
GPU: Radeon RX 580 8GB
Power Supply: EVGA 600 B1, 80+ BRONZE 600W

Ooh, yeah. Very possible. That PSU isn't the worst, but isn't the best by a long shot. It's old now? I'd say at least 5 years. Defo due an upgrade.

A decent 550-650w will do nicely. Seasonic Focus Plus Gold, EVGA G3, Corsair TXM/RMX/RMi, depending what price they may be locally. Any of these will serve you very well. They would all have a 7-10 year warranty and are quality PSU's.
