Re: Junk Fu or not Junk Fu ...

Thanks Behemot!

I suspect that in this particular case the suffix letters may make a difference. The CM6805(A;B)/CM6806A in your pdf are 10-pin SOIC:

Unlike the CM6805BSX or CM6903A, that are 9-pin SIP:

Re: Junk Fu or not Junk Fu ...

Addendum - Fine tuning VReg

The +12V voltage was still a bit low for my taste, beginning at 11.95V when PSU was idling (out of comp, no load, just jump-started) and dropping to ~11.7V @ ~250W load ...

[CENTER][/CENTER]

so I investigated about what could be done on the subject.

In this PSU the PFC/PWM controller is a 9-pin CM6805BSX, of which I can't find a datasheet.

However a did find a [url=http://www.championmicro.com.tw/datasheet/Analog%20Device/CM6903A.pdf][B][COLOR="Navy"]datasheet...

Re: Junk Fu or not Junk Fu ...

Yep did some thinking on replacing the bulk cap.

The OEM Elite is 22x35mm. In GPA there is very little if any room for a wider cap, and height clearance is ~50mm before cap sticks its head in the fan.

There is a nice series from Rubycon that comes handy when parking slot for bulk caps is tight: [url=http://www.rubycon.co.jp/en/catalog/e_pdfs/aluminum/e_mxk.pdf][B][U][COLOR="Navy"]MXK[/COLOR][/U][/B][/url].

One could squeeze a MXK can of 22x50mm with 390uF 400V, or 330uF 420V / 450V.

Interesting, good to know.

If you mean the bulk cap, I left the OEM Elite GM 400V 180uF 85C. Rachitic in size but should do for the application.

Re: Junk Fu or not Junk Fu ...

PSU works fine with 2.2uF Panny FCs in place of 1.0uF Junk Fus. No explosions.

BTW voltage regulation is much better after fitting real caps (Panny FC/FM/FR of 2200 & 3300uF) than with the original manure (Junk Fu WG/WL and Su'scam SD of a rachitic 1000uF).

Interestingly the only two decent caps that came OEM with this PSU are the bypass cap for the TNY176PN +5VSB PWM controller (Chemicon KY 50V 10uF), and the first +5VSB filtering cap (KY 16V 1000uF 8mm).

Hi guys! I'm recapping this PSU and I'm not sure about what to do with those three small guys that I've labelled with the number '3':

They're 50V 1uF Junk Fus (thus crying out loud for replacement ), but the thing is I don't have any 50V 1uF caps at hand. However I have some Pannys FC 50V 2.2uF around.

What would you do?:

Re: Will it explode?

Thanks Momaka.

Yep the best option would be to get a decent old-style PSU with plenty of amps on +5V, then recap and recondition it.

But I'm thinking about people that like keeping retrocomps alive, but can't recap and will never tinker inside a PSU. Old PSUs with OEM aged dubious caps inside [I](like those Fuhjyyu-loaded old Antecs )[/I] aren't a reliable option for them.

So if you had to power an ancient +5V·heavy Athlon Classic/XP system, and you had to choose from amongst brand...
