I was thinking, why not run the l.e.d. lights and my case fans off a second powersupply? Everything else would run off the first powersupply. I could find room in my case to put the second power supply in so right now that's not an issue.. The power supply i have in right now is 420 Watts, it seems to be working just fine on its own, but i just want to see if i can run two seperate powersupplys simotaniously. My other one is not in use and it's 300 Watts. Now the only problem i can foresee, is how to boot this second power supply. Any ideas?
