Near the PSU. Wiggling the cord at the plugin site or anywhere along the cord leading the PSU produces that behavior.
Most likely something jarred loose or an open short occurred (crack) inside the PSU during transit.
That was the thought I had, or something along that lines when the cats knocked over the PC... because prior to that event, the PC itself was fine. So, replacement time it is, then. I'll probably RMA it as well.
Looks to me like you have a pretty good idea on what you want in a quality PSU this time.
The GTX760 appears to be a bargain price/performance card at the moment. I like the Gigabyte or MSI OC version
at the moment. 3 yr warranties, thoughtful use of heat sink, fans and high temp components already maximally OC'd by the maker for the electrical requirements of the GPU. 500W min.
Hmm, nice, I like the Gigabyte version as well. So, 500W minimum... which means I should probably get something with a little more headroom, I think.
3. Been planning on purchasing a UPS...give my PC and attached peripherals some run-time, anywhere between 15 minutes to 24+ hours.
I'd shoot for 7-10 minutes with the idea of automatic shutting down (software) if power doesn't return within 4 minutes. That allows you time to save your work. Most power comes back up within a minute. If it is down much longer it usually is down for several minutes or longer. You can usually turn off some peripherals to lengthen drainage, and if at night having at least the light of the monitor can help fish out a flashlight, plus you want to go around and start to unplug electrical components before the power comes back on if possible to avoid spikes/surges.
That's true. I'm also planning on getting a separate UPS for the modem and router. I suspect the things will have ridiculously long uptimes given their power drains are so little if at all.
My surge protector says the outlets are grounded.
Works for me.
So I should take it as Gospel, so to speak that the outlets are grounded? I'll be moving very soon, so I'll be replacing the PSU with a new one. Hopefully with the replacement at that time, this annoying no-warning reboots will be fixed. If not, I will be angry, because it means I'll have to fall back to my spare PC build. It's nearly identical to this one, the difference being the motherboard revision. (Rev 4.1 instead of Rev. 5.0 as for this motherboard.)
... Or if someone has a spare PSU that I could use that they themselves don't need...
