Re: Is Seasonic SS-660KM PSU ErP Ready

Lucky you! I'll just say this about the throttle-by-wire "advanced feature" in mine:

I concur, IMHO semi-fanless is as stupid as start-stop in automobile engines. :trashcan:

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:

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...

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...

Re: Junk Fu or not Junk Fu ...

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...

Re: That's a lot of primary cappage

Indeed that's what they did on the ZALMAN ZM400-LE, 280uF combined:

Re: Junk Fu or not Junk Fu ...

It's a CWT GPA platform (http://www.orionpsudb.com/antec) inside an Antec VP-400PC.

I think I'm going to replace the 1uF Junk Fus with the 2.2uF Panny FCs and see what happens.

Re: Will it explode?

I meant to ask what exactly phisycally limits the combined +3.3V & +5V output to 130W.

So it is the transformer and the drive circuit, and they'll blow if I ask say 140W from +3.3/+5V combined on...

Re: Will it explode?

OK so (just to be sure) where does exactly this '130w max +3.3V & +5V combined rating' come from?

This PSU has one 30A rectifier on +3.3V (30A * 3.3V = 99W) and one 30A rectifier on +5V (30A * 5V...
