Hi:
I am trying to repair a 1000W cheap power supply, but so far, with no much success.
The ATX has stable 5V STBY.
When shortening PsuON to ground, it triggers all voltages for a fraction of a second and then disapear (I see the leds flashing for a moment from the ATX tester)
- I removed and tested the capacitors. They are OK.
- Removed and tested the Output rectifiers from the secondary.
- Removed and tested the Mosfets from the primary.
- Outputs are not shorted.
- Overakk review of the solder joins.

Hello everyone, I received a PS3 console with the issue described in the title. I gradually measured the console (both the PSU and the motherboard) but couldn’t find anything—everything seems fine.
I planned to remove the casing and test whether the voltages appear on the coils, but after rewiring and turning the console on without the casing, the system actually booted, which blew my mind (it’s been seven days that I’ve been dealing with this). The processor started heating up, so I quickly turned the console off and tried reinstalling the heatsinks and turning it on again....11-22-2025, 01:47 PM -
Hello Newbie here..., few years ago i bought a broken twin frozr gtx 750, seller said that theres heavy stutter issues in every game tested. i inspect it a little and find two tiny capacitor torn out near the pcie x16 gold pins, i assume it will be running in 8x ? the furmark-like gpuz test showed that there's indeed a heavy stutter and low fps but i tried this with EXP GDC and a laptop.
Few months ago i bought a broken Twin frozr gtx 750ti with unknown issues, i didnt test it and jump straight to thinking that i probably need to solder everything that the gtx 750ti have but gtx 750 didn't...11-07-2025, 11:12 AM -

(All the Electrolytics are brand new.)
I started a new one, hope that's ok, because my question is different now! (Strangely enough, after I walked away for a few weeks, it stopped lighting up at all!!)
I am determined to fix this power supply because I have the skills to replace bad components, I just need to find out...
Working...
