Default How do you reduce ripple?

Hi there congratulations on this new forum, I've had a few hours looking around and it's full of useful information already, having been a fan of jonnyguru's reviews though it's hardly surprising, also nice to see some great people from other forums here as well.

Anyway after reading most Power supply reviews I bought a OCZ GameXStream 700, I would have liked the Corsair 620 but at the time it wasn't available sad really because I would have much preferred that one but the supplier didn't stock it and the OCZ was a replacement for a Liberty that literally blew up taking out the RCD's in the house.

I notice the Epsillon and GameXStream both suffer high ripple and wondered if there was any components that could be changed to fix it or is it a design problem?

I'm not sure. Been trying to figure that out myself. Maybe someone should re-cap one and then we can test it again.

Do you have to return the test units? If not I would offer to recap one I'm handy enough with my soldering done loads of electronics work only I'm useless with the knowledge I just work from diagrams and do things other people have already done.

Thanks for the super quick response

Actually I was thinking about doing that on the 600W I sent you even before I knew about the ripple issue. IIRC, I couldn't find any good caps with the right diameter to replace the OST's in there.

I'd be really interested if this can be done and I don't mind helping with the costs if required.

I frequent many forums... that's one of them

I already have a recapping article planned for Antec... wouldn't be too much trouble to add a few to do an Epsilon. The problem is finding something to fit where the OST's are. The Capxon 1000uf caps on the output are the easy ones... was debating increasing the value on them.

I'll send the Epsilon back to you Wolf.

The OCZ is gone. Got totally disassembled and it aint going back together any time soon.

Wow you lot don't mess around do you ;-) I think this will be very interesting to see what difference it makes, I've just been looking on here:
http://www.badcaps.net
To see if they might be able to suggest where to get the right size caps.

Cool - I'll do it and the Antec article at the same time and send everything back to you in one shot.

Edit - the problem caps in the FSP are 16v 2200uf 10mm if memory serves. Will look into recapping with 2700uf instead, since I'm pretty sure these are for the 12v rails.

Oklahoma Wolf, I'm not sure if you know, but there are NO dielectric pads between 2 of the 3 fets//sinks, so 2 of them carry a hella punch.

This should be intresting.
