If I’ve made any mistakes in here or if I've overlooked/missed anything important, please do point me in the right direction. Would the high leakage and high ripple current pose any issues? Assuming I should use caps with the same capacitance, would the 200uf difference be significant enough to cause issues? 2000uf caps specs: 1000uf caps specs: Original Nichicon caps specs: Other references: (Capacitance and ESR for replacement VRM caps mentions sticking as close as possible to original specs) (Replacements for Nichicon HM, note that as far as I could find these caps are not available) (Polymod discussion, discusses halving uf rating for VRM caps and half-capacitance rule) (mentions halving capacitance while keeping same ESR rating and at least OEM ripple rating) (mixed information on specs of capacitors to use) (use the same ratings) (use the same ratings) Any feedback or suggestions would be greatly appreciated.
There are also 1000uf caps which have a leakage current of 630uA, which is an improvement (assuming the low capacitance isn't an issue) but still much higher. They're rated at 6.3v and 2000uf, but they have a high ripple current compared to the OEM Nichicon caps (5900 vs 2550 mArms), and the leakage current (as far as I can tell) is way higher than that of the OEM caps, at 1260uA. I found some really nice-looking German poly caps with a low ESR rating (12mOhms 100khz vs what I believe is 13 mOhms (listed as impedance rather than ESR)) meant for VGA cards and power supplies, but I am unsure if they'd be suitable for this application. The same case with non-VRM caps I've heard you should use poly caps with half the capacitance but I've also heard that capacitance should be the same. Second is the half-capacitance rule - for Voltage Regulator Modules/VRMs, it seems that you should use poly caps with half the capacitance? I've also heard that the capacitance should be kept the same. From what I’ve read and understood, ripple current and leakage are important to take into account, but I have not been able to find an exact match. Firstly, what exactly do I need to take into account aside from capacitance, voltage, size and lead spacing? I’ve found ratings for ripple current, leakage current, tangent of loss angle, and dissipation factor. Two caps totally blew out (and funnily enough the computer still ran fine) and the rest are looking a bit puffy and need replacing. A total of 11 caps rated at 2200uf and 6.3 volts (10mm x 20mm), and 4 caps rated at 1800uf and 6.3 volts (8mm x 20mm) need to be replaced. As far as I am aware, there isn't a direct replacement for these caps.

I want to install quality caps that are suitable for this application there are some alternatives but they're not ideal for motherboards.

While from a practical standpoint it's not worth recapping such an old PC because not much can be done with it, but I like old computers and I'd like to get this one up and running. 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. I feel the easiest thing to do would be to replace all the blown caps with polymer ones. 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.

Howdy folks, I have an Optiplex GX260 that blew a couple of those troublesome Nichicon HM series (ultra low ESR) electrolytic capacitors.
