Hello peeps,

After alot of attempts with different techniques and failures I have made my own mod on how to up the 3.3volt rail on my enermax PSU.

I intitialy tried all present methods available but they didnt work. So i came up with this solution.

I can now adjust my mod to over 3.6volts with prime working away!!!

Here are my adjustable pots (3.3 and 5/12 volt rails)

Special thanxs goes out to E-blitz(amdforums) who has been ever present throughout the whole process, without his help this mod would not have been possible. Also thanxs goes out to the other peeps who were the first pioneers of a mod for potless PSU's their input has also been necessary for this accomplishment.

Time to go, any help needed just post here :)

I did the 3.3v mod on the same exact PSU a few weeks ago, except I did it without taking apart the PSU. On the skinny orange (normally brown) 3.3v wire coming out of the ATX connector I used a 100 ohm resistor, and a 10K VR to ground on the PSU-side of the 100 ohm resistor. I didn't try going any higher than 3.6v.

Can you test stability with the above voltage? For examples, try some 3dmark2003 ten loops, playing games 1 hour, or run Sisoft Sandra 1 hour.

It's interesting to know if your machine remain stable after the mod. In my case, I lose perfect stability when the voltage at 12.352V, 5.134V, and 3.488V. Don't know why? damn......

I don't know with other people's doing? let share our story....
