Question about Enhance Technology SFX-1211J, Enhance 110W 1211J Power Supply (SFX1211J) Power Supply
I have an enhance sfx1211j power supply that had a bad fan and swollen output filter capacitors. Even in this condition the PS was producing voltages as the computer was still running. I replaced the fan and the filter caps and now the PS won't power up the computer. The PS DOES turn on unconnected to the computer when you ground the green wire and seems to have all the proper voltages. I verified this by comparing its voltges to that of a brand new unit wire by wire. Even the levels of AC ripple are the same. The new unit does power up the computer. How can this be?
Make sure, that you did not made any short on pc-boad. And check polarity of new capacitors. They are easy to reverse

Hi when under load the PSU voltage is obviously dropping off, With a Power unit, there are 3 things to keep in mind. They are too expensive and too dangerous to repair, Also inexpensive to replace. Regards mistyman
