Computer keeps powering off without warning

I'm running Windows 8.1 on a newly built PC only a few months old and since yesterday morning my computer keeps shutting down after being on for only about a minute or so. Sometimes it stays on for a bit longer, but not more than ten minutes at a time.

I've ran an entire virus scan on it and have come up with nothing. I've tried unplugging and plugging it back in and still nothing.

My only other assumption is overheating except I like to think I have a pretty decent enough fans to prevent this from happening. I've tried maximizing the fan speeds in hopes of fixing this problem yet it's still occurring. I'm not entirely sure I'm doing that part correctly however. I did in the BIOS setup.

I even let the computer off overnight and this morning it still shut off relatively soon after I powered it on.

If anyone can help or offer any insight, I'd really appreciate it as I don't want to go out and buy additional equipment to keep my system cool if heat isn't the case here.

Thanks, and I've attached my build list below to give a better sense of how my PC is put together.

Solution
I would say it is a power adapter issue. Sometimes the power adapter is either doesn't have enough charge and it switches off. This happened to me a lot with my laptop. I don't know how to solve that on a desktop unfortunately.
