Msi ms-6577 (hp)

Hey Guys,
I want to replace the capacitors on this board. Most are swollen, some are leaking.
This computer came from my son-inlaw and it took me almost 2 hrs just to clean the dust out. After I disassembled it. I'm thinking this was a major contributor the the failing capacitors.

Listed below are the capacitors I need to replace. I have already replaced 6 capacitors with Rubicon 10mm x 20mm 2200uf 6.3v. (direct size replacements)
These are what I need and can anyone tell me what is the best brand to put in?
8mm x 16mm - 1000uf 10v (need 5)
8mm x 20mm - 1800uf 6.3v (need 5)
10mm x 20mm - 2200uf 6.3v (need 8 more)

Anyone have any suggestions as to maybe I should go with a higher voltage rating? What does the uf rating have to do with? Can I go higher or lower on this?

Thanks

Panasonic FJ / FM series
rubycon MBZ / ZL series is gd.

you can only go higher and NOT LOWER voltage

I agree with ant3203 Never replace an electrolytic with one that has a lower voltage rating.
the capacitance value of an electrolytic capacitor is "easy to please", and an exact uF replacement is not necessary, the uF or "microfarad" is a moderate unit of capacitance,capacitance value indicates how big an electrical charge the capacitor can store. For example, you can replace a 30 uF with a 33 uF or replace a 20 uF with a 22uF. If you can't find a close replacement...better to go with a higher uF value than a lower uF, just make sure you have room for it to fit.
The old "rule of thumb" when replacing electrolytic capacitors is to not wander to far from the 20% tolerance of the original capacitor's farad rating.
also badcaps sells a kit for that mobo https://www.badcaps.net/store/produc...products_id=96 might be worth checking in to..

8mm x 20mm - 1800uf 6.3v (need 5)
10mm x 20mm - 2200uf 6.3v (need 8 more)

That's a start but need to know the make [brand] and series [model] of the old caps before the correct specs can be looked up.
.
For example a ZL is no where near good enough if the old cap's grade is up around FJ or MBZ.

Hey Guys! Many thanks for your input.. Looks like the kit is the way to go. I sure wish this was a model I could just toss out.. But, gotta keep it alive..

I am also going to see what brand they and series they are.
