Guys,
Can I replace 3300uF Caps on my mobo with 2200uF ?
Thanks

No. Always use the same VLESR type if not polymers.Please Do Not PM My Page Asking For Help Badcaps Is The Place For Advise, Page Linked For Business Reasons Only. Anyone Doing So Will Be Banned Instantly !

Re: Replacing 3300uF with 2200uF ?
ok, how about 4700uF ? I can't find 3300 in my box...Comment

Re: Replacing 3300uF with 2200uF ?
caps have a ±20% tolerance so the caps u replace must be within a ±20% range of the original value or else it could likely cause problems with the circuit.Comment

If it's just a DC output filter then I would personally go for the 4700uF..."We have offered them (the Arabs) a sensible way for so many years. But no, they wanted to fight. Fine! We gave them technology, the latest, the kind even Vietnam didn't have. They had double superiority in tanks and aircraft, triple in artillery, and in air defense and anti-tank weapons they had absolute supremacy. And what? Once again they were beaten. Once again they scrammed [sic]. Once again they screamed for us to come save them. Sadat woke me up in the middle of the night twice over the phone, 'Save me!' He demanded to send Soviet troops, and immediately! No! We are not going to fight for them."

That may be OK if the new caps have much lower ESR/higher ripple current. So for example replacing something similar to Rubycon MBZ with MFZ/MCZ.
I seriously doubt those 4700uF caps are ultra-low ESR in the first place. I only know old low-ESR caps used in the PIII-early Athlon XP era. Those were the best at that time so they put it into VRM. Today they are only in the low-ESR range. Better list what you got there and what motherboard it is.Less jewellery, more gold into electrotech industry!

I was thinking, making a cable and connect it to the board, because I don't have the exact size...but in the other hand it looks ugly and will affect the performance because of the wire....
I bought the right capacitor already, I'm waiting it's being sent now..Comment

Re: Replacing 3300uF with 2200uF ?
And we do NOT talk about the series, voltage and capacitance.
Those values are, sometimes, utterly unimportant, what's really important are the other values of the cap!
And there are things like ESR, the ripple current the cap can endure and some other things like lifetime and so on.
So if you would replace a low ESR 3300uF cap with a general purpose 4700uF cap, the cap may pop pretty quickly and other bad things may happen.
So please state the name and the series of the caps!
And sometimes in a CPU VRM, it can be better to replace the caps with 470uF or something like that - but not wet electroyltic caps but polymer caps instead...Last edited by Stefan Payne; 07-12-2016, 06:11 PM.Comment
