Loading Windows, PC shuts down by itself.

I just got a Seasonic M12 Bronze 620W unit. My parents were telling me, "Use that 970 with your 500W unit!"

Outervision PSU calculator says 508W @ 90%.
AMD FX-8000 series CPU gets minimum 70% on Dying Light, at least 3x more powerful than the i5-760.
i5-760 will CLEARLY be above 90%.

Do the math.

Now that that's out of the way, now you know why I got this new PSU.

Anyways, I set it up, excited to turn it on, uninstall drivers, put new GPU in, play some games,

Gets past mobo boot screen -> loading windows. Then it turns off by itself.

I've heard stories of Seasonic units dying not-so-quiet deaths, and I'm afraid that trying to turn it on will result in the same thing. But I live in the US, and supposedly the quality rules say "PSUs can't explode," seen low-cost ATX supplies here that do not obey that rule, but are still out there anyways.

$60 PSU. Should I be worried? This PC means a lot to me.

Meanwhile, I'll just put together new systems on PCPartPicker. Might help me get some new lineups together.

I would double check the wires, the seasonic is fully modular. More than once have I seen cables not inserted all the way that can allow the computer to post, but fail under load. Especially check the 24pins on both the motherboard and the PSU!

Pretty sure they're all connected.

I got it to boot! Just a loose cable.

Thanks for the help.
