[HighTest]

I get a similar.... restore power, boot and then my rig shutsdown and reboots itself again into no screen etc... so I soft reboot and all fires up good.
No 'Post Failed messages', or anything like that

I had very similar symptoms, but then my powersupply smoked (Originally an Enermax Whisper II) and I purchased a new one. Didn't really go up in power as it wasn't necessary according to all the power calculators I've used, but I did go a whole level up on quality.

Now I don't have any of the described problems with my Zalman ZM600-HP. A power supply that is extremely stable on the rails, even at full load according to JonnyGURU.

While your supply may still be working, is it possible (as the specific model isn't in your sig, just it's rating) that you could have one that is unfortunately outside of good stable rail specifications? Have a chance to borrow one of reputable quality and see the result?

If you could test one, without first purchasing, you "may" find that this is the cause of this problem for you. I recommend the try before buy, because I'd feel bad if you went out and bought one on my recommendation and didn't have any change in result.

Also, check the rating on your Powerware 5125a UPS. If your UPS is too low on rated volt amps, when your supply is at full load, you'll run into stability problems even with a quality power supply. Quality UPS's of sufficiant rating must be used with the appropriate power supply. Make sure to add all the peak amps of all the assorted peripherals that are also connected to the UPS, something could take it over the top and you'll get poor power results (a really good UPS will shutoff due to overload, a poor one will provide under power that even a 99% PFC supply cannot adapt for).
