Could you run all your usb devices off a hub, then power it (hub) with a dedicated 5vpsu.?
I know, these threads suck, but I need an experienced opinion. I bought an Opus 150w, assuming that it would be more than enough for my system, but I may have underestimated my power draw as the scope of my build expanded. The online calculators put me around 160w. To sell this Opus and buy a 200w+ PSU would end up costing a serious chunk of cash.
Ordinarily, I'd err on the side of caution, but I do have a power hungry P4 system (3Ghz CPU, 128mb video card, DVD Burner, etc.) on a 185w PSU that's seen daily use for 3 years now. What do you guys think?
