First Build!!! Advice wanted

The VX550 runs on 1 rail rated for 41 amps.

IF you are planning on going for the PCP&C Silencer 610, keep in mind that cable management in the Antec 900 is a fairly difficult task.

unless you mod it

oops... my bad... I think I've decided on the 550VX

Good info on the number of rails thing... that does make sense, and the 550VX does look like the best buy as far as single rails.
J/W though, what kind of devices use 20a or more? How much amperage does say an 8800 Ultra draw?

 

[cinaibur]

^^ that's exactly what I was wondering. What about an overclocked 8800 GT?

Well, I just found the newegg power supply calculator Newegg - Power Supply Calculator
and with normal stuff like 2GB DDR2, 7200HDD, 1 optical drive, a regular motherboard, and an 8800GTX (9800 will surely be more power draw) It recommends a 565w.
If you put it up to 2 DVD-RW's, which I plan to have, it jumps you up to 604w... I might go 4GB ram some day too...

I dunno if the 550VX would be enough? yeah it's single rail, but... ?

here we go again... RAILS MATTER WATTAGE DOESN'T!!! a 800w PSU with 10amps on the 12v rail is still bad compared to a 550w PSU with 41 Rails on it....

the stuff gets powered by the Rail....

 

[900RR]

so what would you say a 550w single rail PSU is equivilent to in the calculator.. multiple rails wise I guess?

SLI GTS with 4gb ram, 2 dvd rw's, q6600 etc... is saying like 741w... asiming they are assuming multi-rail psu's how much wattage can you add to the single rail to figure? 30%?

550 single rail about equivilent to a 715w 3 rail would you say?
