My Predator G3-605 has been completely shutting off while playing, mid game. (i7-4790 3.6, 16gb..

Good afternoon, where ever you may be. I've purchased my Predator G3-605  (i7-4790 3.6,  16gb, GTX 970) roughly 4 years ago and I've never had a problem with it until recently in the last 6 months or so. I would play games such as (Fortnite, DayZ, Apex, etc.) and it would just turn off. I would feel the back vents where the PSU is and it would be pretty hot. I've asked this question on Reddit and some said that the PC might be taking more power than the PSU can handle. If this is the case, how do I go about buying a new PSU, what PSU's are compatible with my PC? And what wattage should I shoot for since the one currently in is a 500W. 

This is the PSU on eBay (https://www.ebay.com/c/1133093305)

Any help or advice would be greatly appreciated!! Have a great rest of your day!

That is a real standard ATX PSU. They all have the same physical dimensions and mounting holes. I'd look at 650W and 750W supplies, I doubt if you'll need to go beyond that and they will run slightly cooler when running at a smaller percentage of full load.

Now, as to why you're running hot in the first place, since the PSU and everything else are actually the same as they were before when you weren't having heat troubles... A typical system will gradually build up a coating of dust on pretty much everything over time, this even includes the fan blades though they're spinning all the time. It can be even more prevalent in the heat sink that's used to cool the CPU. It's very worth while to periodically (say every six months or a year) tear things down a bit and vacuum to get that dust out. Do a full shutdown, pull the power cable and the side panel and inspect. I'm betting you'll find a bunch of dust in there just waiting for your vacuum.

I'm not sure why the original PSU link isn't working so here is another one.

Thanks for the response Bill. The dust coating would make sense, but every time that the computer dies on me, I would take it into my garage where I had an air compressor and I would blow out the whole thing. I don't think the problem is with the dust rather maybe just the PSU, I'm going to look in to which PSU's are compatible.. Thank you again!

Very good then, make sure to let us know what you find out.
