I have a 5900x to replace my 5800x (actually a fair bit of performance difference). It came with the CM. I can't actually find any article of a direct comparison between the two. The Fuma has a Higher TDP but the CM looks to have a more solid build. Fresh AS5 either way.Scythe Fuma 3100.00%1Cooler Master MA620M0%0

I am attempting to repair this. Circuit is quite simple, but i a quite stuck at it for a long time. so today i try to ask for new ideas. my challenge is to under stand what mistake i made. I had repaired not lesson than 50 pcs of various brands ATX psu . main pwm chip is Cm 6805 Sip 9 .
5VSB is fine. When I short Pson, totally nothing happen. I check , the Cm 6805 VCC pin2 did have 16v, But totally nothing happen. I changed to a good chip from another good PSU. Same thing.
What other pin should I check such that it will result in no start up at all ?

Got this from my kid with a fault on primary side. Main power supply here is AC 220V. All caps were Ok, testing with 2 series lamp of 70W each, got a bright lamp
. Checked main heatsink one by one with my component tester and found one 3 leg buddy MDP18N50 that passed away. Got same replacement after a week, tested, short was gone, now I got 310V on primary.
Happy as a dog, added one case fan for some load and the fan of the PSU. Tested purple wire, got 5.1V, great!. Shorted green and black, fan spins and after about 5 seconds shuts down. I was able to measure doing several iterations... -
Happy new year.
This PSU use WT7527V supervisor.
On purple cable i have 5V, but on #4 of WT7527V i have 0.21V.
If i try to start PSU with short between green and black it star for a second and stop.
For what other to check? I now that is needed more info but i don`t know what else to share -
Hi all,
The PSU in question had a bad power switch. There was not physical feedback when switching on and - if memory serves - it was always ON even when in OFF position.
I researched a bit and got some replacements.
The replacement "got stuck" at first power up - as in "it's now always on".
It looks like this PSU has a pretty large inrush current as my lights flicker when I turn it on with no load.
Probably the switches I got are bad quality but I was wondering if someone could recommend a good replacement?...
