I had my computer in storage for about 2 years, had taken it out once about a year ago and set it up and used it, worked fine. I recently took it out and set it up at my GF's apt and nothing, would power up at all. It was an Enermax 550W (i think) Model number EG701AX-VE(W). I am really disapointed in Enermax. I bought a new Antec Trio 430W and is working fine.
