I worry about the dual +12V rail ( https://www.amazon.com/Thermaltake-TOUGHPOWER-Modular-Supply-PS-TPD-0750MPCGUS-1/dp/B00IUQRPQS ) but there is a single rail and even with a dual rail unless there's a dozen HDDs I think this gets a pass.
BE SURE the BIOS is current and google that model motherboard like this:

Seems like this board has a lot of complaints about random shut offs. See if anyone has fixed it.
