That doesn't seem too bad. (also, 450W/12v=37.50A, 37.50A/2=18.75A per rail) Now, i am also pretty sure that 18A is the max draw per rail, but that may not be what is available all the time. I would start a new thread in PSU's section and see what some of the more knowlegable PSU people think. It can get quite confusing between what is listed as available and what is actually there. Since you are running 2 hdds, one optical (assuming), 4 sticks of ram, PCI card, GFX card, fans, CPU etc., I can easily see that PSU getting taxed pretty heavily. PSU's are one of the mroe overlooked things in a system, but are by far one of the most important.
