Codegen 550w (PFC)
Codegen 550w PSU (PFC)
Following the demise of my last 'yum cha' PSU (purchased within a CoolerMaster case) I picked up this Codegen 550w PSU, stability seemed good & the twin fans helped to expell all those nasty hot gases from within my OC'ed Barton system's case
I've only since built a s939 system based around an MSI K8N Neo2 Platinum & 3700+ San Deigo... anyway I'll cut straight to the nitty gritty, after some odd OS symptoms, I tested the loaded voltage lines only to note significant 12v fluctuations 12.19 ~ 12.31... this can't be healthy I thought
On dismantling the PSU, I found no sign of capacitor bloating on the TJ & Peace components (see pic' below) installed, construction quality really was quite ghastly (monkeys with soldering irons), so while replacing said capacitors with SamXon equivalents, I also resoldered poorly seated components
Items replaced...
4 x GC Series SamXon 2200uF 10v
1 x GD Series SamXon 2200uF 16v
Interestingly there was a freakish size difference between the SamXon & 'Peace' 16v capacitor
the end result of all this tinkering however was a far more stable 12.21~12.22v under 100% loading (F@H) unless you consult the inaccurate 3rd party monitoring software which is claiming 11.66 ~ 11.96v
