Ok guys, After couple of days waiting for parts I was able to recap completely the Fuel PSU from Sparkle Power Int. Model FSP460-60PFN. Issue with it, sometime was felling on the 12v rail, will go lower at 10.2v. After open the PSU, and inspection, a good amount of capacitors where bulging already. I decided to replace all of them. Now the power is perfect on all rails and the system is back online

Nice to hear you were able to repair it by replacing the capacitors :)
The existence of the ATX adapter board is good, but unfortunately it is hard to find ATX power supplies with sufficient capacity on the 3.3/5V rails, so this should be helpful.
