I am upgrading my crappy 350 watt power supply becasue I am adding additional cold cathodes and want my sysytem to be doom 3 ready(powerful vid card that sucks up juice). I have decided to go with a Antec true power but I cannot decide on which wattage I should purchase. It is either gonna be the 480 or the 550 watt version. Here is what the power supply needs to run:

AMD Athlon XP 2600+ (not oc'd)
6 X quad blue 80mm led fans
1 Rheobus
2 Optical drives
1 Floppy
1 Hardrive
2 X 12" cold cathodes
2 X 6" cold cathodes(adding later)

What do you guys think? Can I get by with the 480 watt?

I am also going to sleeve the power supply. I have heard you can use a hairdryer for the heatshrink but I was wondering, can I use my hot glue gun(no glue of course) for heat?

You should be able to use the 480w version. I don't see how a hot glue gun could be used on heatshrink? I doubt it would work.

nah, u would melt it. u would be better off just holding it away from a candle and letting the heat from that shrink it.

or cigarette lighter

ya, but then u have to burn your thumb holding the lighter and you only get one hand to move the heatshrink around with

sometimes you make do w/what ya got:p
