A friend an I bought identical hardware in 2003. For mobo we picked the Soltek SL-75DRV5. Recently, he was having some flaky behavior with his video card, and he noticed several bad caps on his board. At least 5 were bulged and leaking yellowish residue at the top. I took a look at my board and noticed 2 that are bulged and leaking residue.

Just a quick update...
I re-inspected my motherboard last night and found that all 4 caps nearest to the CPU are bulging, but only 2 show any residue of leakage. The two that aren't leaking yet aren't nearly as bad, but they are obviously beginning to form the bulge. These caps are 2200 uF 6.3 V. At the angle in my case, I was unable to read the brand, but I think it might be GSC (known to be prone to failing, and known to be used on other soltek boards of this era). The other caps on my board appear to be different smaller sizes, and likely from the same company, but they all appear to be intact so far.
My friend's board has the same problem with those 4 nearest the CPU, though his show even more leakage. He also has a smaller one that is near the AGP slot that is bulging and leaking. He couldn't read the size of that one with the video card plugged in, but he will be taking that out soon to get a closer look.Comment

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:

Hello!
I have two projects on my work bench. One is a friends dead JBL Xtreme speaker with a blown voltage regulator and corresponding bulged and shorted cap. That cap has clear markings so I know what replacement I need for it.
The other project however is a whole different deal. It's a Zoom 9000 guitar effect from the 90th that has developed a devil hound howl when there is no input from the guitar. I'm guessing caps problem. So, since I don't really use this effect anymore I thought it would be a perfect project to learn on.
I have studied the board and... -
Hi all, I've got a 1994 Japanese Panasonic 3DO with 2 leaking caps. Since all the caps are now 25 years old I decided to swap them all before more of them start to leak.
To reduce the danger of another leakage in the future I decided to swap every possible cap with a poly cap.
Has anyone here done that already and give me some hints?
I found a "fitting" (voltage, uF and measurements) poly cap for all but 3 caps. The largest cap is a 6800 uF 25v cap, since there aren't any 6800er polys I'll get a high quality electrolyte one with a higher temp rating. The...10-26-2019, 07:59 PM -
I'm trying to repair two old VCRs, they both have bad caps. One has leaky ones, the other would barely run until I subbed in some caps from another power supply I had laying around (though they are the wrong values). This vcr works for an hour or two, but then the power supply starts whining and the picture gets lines in it. I didn't replace all the secondary caps, so another voltage might still be problematic, or the values I used are too far off.
I've been on mouser and digikey but the options are a bit overwhelming. I just need some new ones that will work. They don't need to be top quality,... -
I did it again – I had to fulfill my inner desire to fix yet another old piece of hardware. This one is actually kind of worthwhile, too – it’s an EVGA e-GeForce 7600 GS AGP video card, model P/N: 256-A8-N542-T2. With the popularity of “retro” PCs from the Win9x to XP era going up, and the diminishing supply of decent AGP cards, it is expected their prices will go up. Or is it? I bought the this video card rather on the cheap side (~$9 USD shipped to my door), because the eBay seller listed it for parts or repair (and correctly noted the bad capacitors.)
So, here is the...
