TC: did you get some esr readings? How did the green ones measure? were the black ones 3300uf like the above board or were they 4700uf?

Tomcat may well be talking of my board--as it arrived in Rolla Monday. Else he has two of this model in the shop this week.

The S12 range is excellent, if they have continued to stay with the United Chemicon capacitor brand, I have not bought one recently...

I tried to peer through the slots of my new S12 430W which arrived today. Among the medium-small electrolytics I could see, generally the trade dress included a medium brown background with white or bright silver lettering. I don't think I can get a useful picture without breaking the warranty seal.

Yes, it was your board, I didn't realize it was you. Just to let you know, it shipped back this morning (Friday Morning).

I still have the old green caps, I'll get readings.

Doubtless delayed a day by President's Day, my P4B533-E came back from Rolla by Priority Mail today. Despite my folly in replacing the power supply, CPU thermal grease, all three case fans, and three major data cables, my system came up apparently intact the first try. Lots of Samxon caps in place of my brown crud infested Taicon's. My three Rubycons were left in place.

One small comment on the Seasonic S12 430W--the otherwise admirably clear summary of connections is misleading in claiming 2 floppy and 6 "5.25 HDD" connections. The floppy is provided by an add-on dongle, which eats up a 5.25 connection. As I had 7 5.25 devices plus two fans, I could have run out of y-connectors, but luckily I had spares in stock.

Also the Seasonic gave me a momentary worry for hot smell. I think what happened is that the 120mm fan finally spun up after about ten minutes of power on time, and pumped out some air which had a little "new PSU smell". It was not much, but I'm jumpy around a fiddled-with system, so was concerned for a minute.

I measured the motherboard 2032 backup battery as 2.7V--worrisomely low for a lithium battery. But I did not know how much state the board would lose if I swapped it (the manual is no help), and did not want to confuse the issue of what the capacitor replacement had wrought. Sadly the mobo location means I'll have to pull a bunch of cables and drives to replace it, but I think I had best do so soon.
