PSU MOD

Did a small PSU mod...

Added a pair of capacitors on each 12V rail, one 2200uF low ESR and one 100uF Tantalum ultra low ESR.

Used textile insulation tape, it tends to last longer.

Put it in thermal shrinking casing.

Well, not all, as I was to lazy to dismantle 24pin connector, so it stayed "ghetto"

Now, the results:

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - BEFORE - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - AFTER - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

- IDLE (12.257V - 12.269V)
-

- VERY HEAVY LOAD KICKING IN (12.177V - 12.204V)
-

- CONSTANT HEAVY LOAD (12.222V - 12.257V)
-

-VERY HEAVY TO MEDIUM HEAVY LOAD TRANSITION (12.212V - 12.254V)
-

Heavy load was made with GTX580 under FurMark, as it pulls more then 990X under LinX,.

That's it! My small PSU mod.
