I was gaming on my PC when the PC suddenly turned off by itself. I tried to turn it on again but it won't turn on, the PSU makes 2 clicks instead of the usual 1 click when the PC is turning on, also the power light and motherboard lights is turned on but the case fans is just barely moving before staying still, turning it off from the power button by pressing it for 4 seconds works just fine.

Quick inspection of the PC I found nothing weird from the smell and the looks

Any idea if it's the PSU or maybe something else? It's a Seasonic Prime Titanium 650W btw
