ASUS TUV4X motherboard - replacing 1000uf 6.3v caps with solid ones from AE?

[fin-william]

I received ASUS TUV4X motherboard which powers and boots to bios but it has swollen capacitors as these very often do.

Is it okay to replace these by using solid capacitors of same value (or higher voltage) and what is the quality in general on Aliexpress, are the solid capacitors there OK?

Shipping costs in my home country will be the most expensive part if I just order electrolytic caps from reputable brands, but in this case it might be worth it as total would be something like 10 euros...

What are "solid capacitors"? Please give an example so we know what you are talking about.

I ordered these:

Phil's Computer Lab did at least one video where he "poly-modded" old motherboard and replaced existing bad caps with these kind, not the exacts ones in the link but similar.

EDIT: as a side note, it seems that the capacitors in the cheapest option (with shipping cost) my country are out of stock now.

ok, so they are still electrolytic capacitors, just with a "solid" electrolytic. More info: https://en.wikipedia.org/wiki/Polymer_capacitor Panasonic OS-CON is an example https://industrial.panasonic.com/ww/products/pt/os-con
If you get the genuine article from AliExpress, it will work. You selected a store and product with good reviews, always a good thing.

I made a typo in the original post, capacitors which I replaced were 1500uf 6.3V, they were made by Sanyo.
Just finished soldering new ones in place and tested that the motherboard posts, it did even before replacements though. I will of course have to do some actual testing later...

I have this old tester which I use, "Mtester". New capacitors were quite close to 1500uf according to it but couple of the old ones which I tested showed much higher values than 1500uf.

this is not absolutely uncommon... but you never know how capacitance is impacted over time, I never saw statistics on it or better to says that common sense would tell that capacitance is decreasing over time.
