Posted: March 28th, 2012, 2:20 pmNo IntelBurnTest? I'm disappointed. You should use that instead of Prime. Nice work on the motherboards, with the PSUs you probably confused the controller pretty bad. It can be made to work with changes in the feedback loop, but it's clear that poly modding a PSU by itself without any regard to other components, will not work.

Posted: March 28th, 2012, 2:51 pmI'm curious, what changes would have to be done to make the polymer capacitors work in the power supply?

I know. I doubt it's worth the trouble of modding it, though, considering that good electrolytics are cheaper and will still last for ages.Th3_uN1Qu3 wrote: with the PSUs you probably confused the controller pretty bad.

It runs on a PIII so i don't know what do you mean by "some older PCs". On the software side, it needs Net Framework 3.5 installed IIRC.

All I got was "The application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem". I assummed it was probably a compatibility issue.

That's the standard net framework error message when the framework is not installed.

Were the original values 6.3V or 10V for +5VSB? Also, how come the "before" ripple is so much lower than that of the HP-D3057F3H review in very similar test conditions?
These power supplies are very common in Compaq and HP branded computers, and I often run into them with a failed 5Vsb capacitor, which prevents the unit from starting. They usually use Teapo capacitors throughout the secondary side, although I occasionally come across units with LTEC capacitors. They use four 2200µF 16V (two on the 12V rail, two on the -12V rail), four 2200µF 10V (two on the 3.3V rail, two on the 5V rail), a 1000µF 6.3V and a 470µF 6.3V capacitor (both on the 5VSB rail).

Posted: September 27th, 2013, 12:31 pm1. The caps were 10 V on the 5sb
2. They were different units and both were used. My guess is that the other one was older and had more worn out caps.
