Hi Going for my 2nd ever mobo install, this one into a new case & new power supply. Going ASUS P4C800-E and a P4 Northwood Reading up on the board, I noted it might be a good investment to make sure the power supply voltage is stable, to avoid spikes. I then found a main power cable that has a large capacitor wired into it to absorb voltage spikes. Is this a valid concern and a worthwhile investment? Only a few $. Thanks!
