OK, found that PS_ON is only 2.8v when connected to main board. See that comes from the vertical board.

Re: Repairing Bestec TFX0250D5W
I have one of these power supplies. The supply doesn't want to power up. 5vsb seems OK. I have a pwer supply tester. Sometimes when I connect the tester in while AC cord connected the supply will power up. Seems the power on circuit is not working correcly. The computer boots normally with a different bestec supply but wiring harness too short to mount ps in computer. Any help would be appreciated.Leave a comment:
