Which of the two is a better pick? Both Nichicons, 22 uF, 25V, and I have the choice of either the KL or the VX. This is for mainboard use. Given the choice between those two nichicons, which (if either) is better than the mobo's stock Supacons? Or would the Samxon stocked by TopCat be better than either of those two? I'm trying to find the best caps of each specs that match the stock caps on the 'board, while still providing an improvement over the stock caps. The board's got good caps for all but a trio of high uF caps that are known defective Nichicons, and virtually ALL the smaller ones are crap caps.

Topcats samxons are good.
As for the nichicons i dont knowComment

Re: For this capacitance and voltage...
I wouldn't recomment either of those two series. I don't think they're low ESR. If you insist on using nichicon, use a new HM, HD or HE series. This (https://www.badcaps.net/store/produc...roducts_id=102) also shlould be OK.I love putting bad caps and flat batteries in fire and watching them explode!!
No wonder it doesn't work! You installed the jumper wires backwards

Normally, I never post repairs this quick after I do them, because… I am usually very slow. But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though.
I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...

I know I've been a little scarce lately (like the last 2-3 years), but I'm still here and still doing my thing with fixing PSUs.
For today's considerations, I have a Seasonic B12 BC-550 [A551bcafh] 550 Watt ATX power supply for you (click on links for full size images).

It's a modern ATX unit with fixed (non-modular) cables and an 80-plus bronze certificate. Here's the label:

Howdy folks,
I have an Optiplex GX260 that blew a couple of those troublesome Nichicon HM series (ultra low ESR) electrolytic capacitors. Because said caps are obsolete, they are pretty much impossible to find on the market; I did find a listing for some but I believe they are counterfeit. I feel the easiest thing to do would be to replace all the blown caps with polymer ones. I am by no means an expert in electronics, and I've found a fair bit of conflicting information, so any guidance or confirmation would be greatly appreciated. While from a practical standpoint it's not worth... -
(TLDR: It was capacitor C6519 [Koshin KZH 50V22uF] and C6515 [Koshin KZH 25V47uF] on the power supply. I have questions at the end)
Disclaimer: I'm an amateur hobbyist and will get things wrong.
Always use caution when working around mains power and high voltage capacitors!
Hey guys, I'm repairing a Denon AVR X6400h for my brother. It quit powering on after a power outage. It acted like this last time there was an outage, but after letting it sit overnight it started working again for a few years. This time letting it sit did not bring it back.

I think this has been answered but I couldn't find the thread.
Someone asked me if it would harm a capacitor (10F [not a typo], 24v) if it was operated on nothing more than 12v.
So, I ask... Does it change any of the capacitor's characteristics/parameters/? in any way if it is never operated near rated voltage?
If operated for years at 1/2 rated voltage, does it accept full rated voltage like it would if it had always been operated at the higher voltage?
Or would it require reforming?
