Simply put, I need a new psu for the system in my sig and the Antec neopower 480 and the OCZ modstream 450 are my two top choices. The neopower sounds like the best psu for the job, but if I were to buy it, I would have to borrow cash from my parents and wait a couple days to get to the bank; and even if I made the rebate, I would probably be too lazy to send it in so it would end up costing about 20-25 more than the modstream. I can buy the modstream pretty much right away, and I cant go much longer without my computer. Is the antec really that much better? Also, how much can my system benefit from dual 12 volt rails as opposed to a single 26a 12 volt?
