Recently we have had quite a few power fluctuations in my area, and I decided to install a UPS in my server rack. I had an old Eaton Powerware 5125-1500 with 1 EBM that I replaced the batteries on, and yesterday I decided to install. Funny enough, about 1 hour before I went down to shut everything down the power cycled on in the house. Everything seemed to come up and be in working order, and I had no issues shutting down both my ESXi host, and my Unraid box (the GIGABYTE GA-Z68MA-D2H-B3 is housed in it). I pulled the old rack mounted 1U PDU's out, installed a new 0U Blackbox PDU, and installed the UPS with the EBM. ESXi host powered up fine, Unraid box just flashes LED's on the front for a split second and then nothing. The fans spin up, for a second, then nothing. I have to switch the PSU off/on to even replicate the symptoms.

Unraid Box Setup
Norco 4020
GIGABYTE GA-Z68MA-D2H-B3
Intel Celeron G530
16GB Corsair DDR3
Antec ECO 620

I have been through quite a few troubleshooting steps.
1. Tested PSU with cheap eBay tester - passed.
2. Swapped a new Rosewill 620W PSU - no difference
3. Reseated Ram - no difference
4. Swapped RAM for a single stick of Avexir (sp?) - no difference
5. Pulled the front panel header wires off, tried a jumper wire to initiate post - no difference
6. Swapped a spare AMD AM3 mobo/cpu in and booted up successfully.

Thoughts.
1. The UPS I have claims pure sine wave, and both PSU have active PFC. The ESX host is a Dell C1100 so I cannot confirm if its PSU is or is not. I dont have a ton of experience with UPS's, and the model I am using is older. I am hoping I do not have an incompatibility and it fried the Unraid box.
2. I tried the Unraid box on both wall power and the UPS and it had the same issues/symptoms.
3. I am leaning towards a new supermicro mobo/CPU combo, but what I don't want is to damage those if anyone things it is a UPS issue.

Any thoughts?
 
My suggestion is try to test your Unraid box PC Z68MA-D2H-B3 system without any UPS or blackbox PDU.
--> Remove the board from the chassis, just has CPU, memory and power supply is attached, Just attached directly to your power source and try to boot if OK.
(This is to check if your board is damage or shorted.)

--> If still won't go, try to clear CMOS and then press power button for 10 seconds to boot from back up bios. (Maybe main bios is corrupted).
--> If you can boot, press "DEL" key to enter bios setup. Update your bios to the latest.

Please do let me know if Ok.
 
I bench tested this board without the UPS or PDU, same result. I bench tested the spare PSU, Mobo, and CPU wit the UPS and PDU and it posted without issue. I ended up picking up a supermicro board with some ECC ram. Installed last night, and everything is back up and running great.
