This is a Sparkle 350W, but the 12v rail has a whopping 34amps, and from what I've heard the x1900 only needs "450w" with 30 amps. So does wattage have anything to do with anything here or is it just a rating? I've read the power supply sticky here and wattage doesn't really mean jack, but 350w just won't cut it for me unless someone convinces me, and 32 bucks for this seems really tempting to buy..
