PSU powering drives

[Rastalovich]

Just like to run this past ya`ll to see what u`r thoughts might be either way.

In the past, it has be wholey possible to have drives, hard, floppy optical - powered from a different psu to the one that controls the mobo. This could be for the pc, mac, atari, amiga.

I`m wondering with the """advances in technology""" that this is still the case ? To explain what I mean, if it`s required:

1 psu (~250w) powering 3 hard drives, 1 optical, 1 floppy++++.

1 psu (~400w) powering the mobo, and connected cards if required.

*** the emphasis being that the drive(s) power is always on whenever the mobo is instigated. So, if u like, whenever the mobo is activated, the drives always - already - have power.

Real life example: Drive psu on all the time, whilst mobo psu can be powered up/down whatever and every1 works well.

This is just an example setup, if this is wholey workable, it may branch into a thought for future builds my end.

Ye you can rig this up yourself with a connector, or buy one to do it

Yeah this is still easyily possible. Check the 1st pic in my rig gallery.

Ah some nice assurances

So if u had a setup with mutiple pcs and prehaps a handfull of drives each, doing some nice math to make sure u don`t go over the top with the watts, prehaps give u`rself some headroom in the unlikely event all drives get written to at the same time, and possibly allow for the fannage.

Think I`d opt for a psu that definately had a rear power switch attached, adapt the 20/24 pin so that it`s always on - or make a front panel thing with it, then check the voltages of the remaining pins to see what u can get out of those.

hmmm.
