The PC does not start up the first time. Could swollen capacitors be the cause? And which ones should be changed?

Question

Electronics

Motherboard:
945g7ad 8ks2h Capacitors banging 6.3v 3300uF
are marked in red. Capacitors
banged 4v 640uF in blue.

The problem is 6v 3300uF I have whole ones. And of the four volts only at 540uF
Is it necessary to buy 4v 650uF capacitors or can I put less capacity? Or can they not be touched at all?

Answer 1

It's likely that they are the problem.
New ones should be installed with the same voltage and higher. Although it is desirable to use native. 99% that LowESR capacitors are required, with ordinary ones it may not start
. The same applies to capacitance, not less, but better the same. Because you may not fit into the dimensions
. High-temperature capacitors are needed, ordinary capacitors will not last long.
It is customary to change not only swollen, but also neighboring ones in the same group.

Answer 2

This is a processor power supply circuit, here we need high-quality low esr conduits similar to those available, it is possible with a high voltage. Everything needs to be changed at once.
