Alexlomm :
I've noticed, that nearly every mobo manufacturer explicitly stresses out that the capacitors they are using are of maximum quality. My question is, why is this particular component so important?
They stress 'good quality', because there have been many instances of crappy ones dying/leaking/exploding.
There was a large instance of a line of Dells where they cheaped out on the caps, and many of them died. I had one.
What does a capacitor do? Basically 'store and forward' for electrical impulses.
