I'm looking into building an NAS type box. I'm somewhat concerned about power consumption because:
a) I already have a P4 IBM eServer running 24x7
b) I have a number of other computers that are on for extended periods of time (MythTV network)
c) I can't find a whole lot of existing information regarding this
So, my ultimate question is:
If I stuff a 600w PSU into a system with identical hardware as a second system with a 400w PSU, will the 600w systems consume more power (assuming the 400w is enough to power the hardware)?
Closer to my actual test I'm hoping someone has done:
Is there a huge difference (regarding power consumption) in using one of the 120w cases PSU's (like http://www.logicsupply.com/product_i...roducts_id/107
) powering a mini-ITX board versus throwing it into a regular case with ~350w power supply?
