System Will Not Power Back On After Power Loss

Hey Guys -

I've got a "server" at home which I depend on for everything.  It alone contains almost 30tb of data plus is a file share, web server, and used for gaming.  Yesterday, the monitoring I had on it said it was offline (I was at work.)  I tried restarting it remotely (I have the BIOS set to always power back on after a power loss plus have it connected to a WeMo switch which I may control remotely) which seemed to work as I got a ping for a few seconds, but then nothing.

Once home, I found that it was off and wouldn't power back on.  When connected to power (and power supply on), the LED power button on the MB was orange meaning it was getting some kind of power, but wouldn't turn on (no fans spin, no drives spin up - nothing.)   I found a note on my door that the power company had come out and installed an "advanced" power meter which is what caused the power to go out and was the initial issue.

Below are system specs plus what I've (unsuccessfully) tried so far to resolve the issue...

System Specs
- Intel i7 3770k CPU / 16gb RAM
- MB: Gigabyte GA-Z77X-UD5H
- Nvidia GeForce GTS 660 3gb
- Storage : 3 partitions
   - C:\ - 256gb SSD (Samsung 850 Pro)
   - D:\ - 28tb Drive Pool (x12 SATA drives pooled using Stablebit DrivePool)
   - E:\ - 1tb Hybrid Drive (App & Game Installs)
- Power Supply: CORSAIR HXi HX1000i (1,000 watt)

What I've Tried So Far
- Bypassing WeMo switch & plugging directly into outlet
- Unplugging power and holding power button down for 10 sec (with PS switch on and off)
- Replacing MB CMOS Battery with new one (Read post of people having similar issue for my MB)
- Clearing CMOS / Reset via buttons on MB
- Powering on via LED Button on MB (When power is attached, the button currently glows orange which is normal - it turns to green when the PC is on I think, but when I press it now it does nothing except briefly makes a clicking sound.  THe MB does have an LCD error code display next to this button, but when trying to power on (or in any other current state) it never displays anything
- Leaving unplugged (with PSswitched on) for about an hour

I've got a top of the line power supply so would hope that it would protect everything else.  It's listing even states "Over-voltage protection, under-voltage protection, and short circuit protection, over power protection, over temperature protection provide maximum safety to your critical system components."  I haven't tried the Fan test button on it yet, but will once home.  Still don't know if it's PS if I know MB is getting at least some power because that Power Button LED comes on.  I just read about the Paperclip Test and plan to do that once home, too.  Also wondering if installation of a new meter causes some sort of different power outage than your everyday storm one.  Wonder if power company did something incorrectly?

So... any ideas or suggestions?   I heavily depend on this server so would like to order parts asap if needed.  Please help!  Thanks!

I finally found the issue that weekend.  I tried the "paperclip test" on the power supply and the fan did not turn on - however - I also verified that my power supply's fan only comes on as needed so that didn't verify much.

Next, I took the power supply out of another system and tested with it.  It came back up!  I'm submitting the power supply for RMA now.  

Thanks for the suggestions, though, guys!
