Re: Is Seasonic SS-660KM PSU ErP Ready
Hello, guys.
It's been awhile, but there is development.
I finally got some time to deal with this PSU a bit. Right now, my PC is running on the SS-400ET PSU.
I removed the screws and then the bottom panel of the SS-660KM PSU case as per suggestion, and then I removed all the capacitors under 220uF. That particular one (KY) was fine, but several of the Rubycon YXG 50V 47uF were measured at 3.4 ohms ESR by the ESR meter. I know that these are small caps, but that looks a bit high.
I have ordered the Panasonic FR equivalents for all the ratings of the YXG and KY from Farnell and they should arrive in a week or two. Then I will replace all of them as soon as I grab some time and hope for the best. Strangely, I couldn't find all of the YXG cap ratings in the Rubycon's YXG sheet. Only 50V 22uF is listed, no 10uF nor 47uF. But for the 22uF it says that ESR is ~0.70, and my ESR meter measured the one from the PSU to be at around 1 ohm. The FR equivalent of that one is rated at twice as low the ESR (0.34).
