Mine worked once. After that I could not get it to output enough voltage to boot the PC. Either way I sent it back a few weeks ago for a refund. No reply. Sent an email 2 days ago to see where my money is. No reply yet. Their customer service was very poor, took 4 and 5 emails and a call from the moderator of this board to get them to say they would refund my money. Remains to be seen if they actually do.
