The 460w should run almost any computer.....
It just depends on what you want to put in the computer....
Lets say the computer has the following in...
2 x HDD
2 x CDR / DVD WRiters (well any optical drive)
The standard stuff like MB, CPU, graphics card etc
USB devices etinfinitum (lots - for those who feel as mentally chalanged as i currently do)
Pretty muchly a DECENT Pc, with a little more than the regular amount of peripherals crammed into it... and yea you can add as many cathodes as you can FIT , can run on a 460 w PSU
If you want to run 8 x HDD, 11 DVD roms etc..... go for the stronger ones!!!!
I have a 450w PSU in this Pc, and i am running:
2 x HDD, 2 x OPtical drives, Graphics, Extra Gigabit LAN, 9-in1 Card reader, USB scanner (pulls power ONLY from PC - no extra power plug), USB powered speakers, External HDD (also pulls power only from USB), USB lazer trackball, USB Pen tablet, USB Video decryptor...... and its only running on 35% power usage....
