![]() Hi All:
I have a 1600 watt PSU that does not output PGO. I thought it is a bad chip first, I managed to get an equivalent, But when I started measuring the inputs of the power supervisory chip I found that PGI signal is also zero. could that still be a bad chip? where it shorts the PGI pin? if not what supplies the chip with PGI signal. where can I get schematics for this power supply? There are so many types of power supplies ![]() The chip is ( 1. HY510N <=> WT7510 <=> ST9S313 <=> PS113 <=>RT7501 ) and i got WT7510 as a substitute. your help would be appreciated. Thank you in advance. The brand of the PSU is SURMA, 90 plus gold. Note: All voltages on the 24 pin connector are available except PGO and all the cables have 12v and 5v to it. Photos of PSU are in the attachment. |
