Hi,

I have a Dell Dimension V450 with a 200W power supply.

I presently have 2 hard drives and 1 cd-rw connected to it. I would like to
know whether I can add another hard drive without changing the power supply.

I checked on the net and it seems it should work fine.

any help with this would be great.

Sincerely,

PvS

hard drives use hardly any power so i seem to remember reading somewhere,
try it and see if it boots ok

if not get a new PSU, a new psu cant hurt

1) It sounds like maybe you've already done this, but you can use a
power supply load calculator, like this one:

....to estimate your requirements. I would try more than one to see if
they agree.

2) The ratings for components represent a peak consumption. Although it
is unlikely that all of your components will simultaneously be at peak
consumption, it's a safe plan to assume that they are.

3) 200W is not very much for a system with a modern video card. Also,
if it is not a good quality PSU, you may not be able to consistently
load it to specification.
 
Hard drives use a lot of power at boot time and not much while running
..Frankly,I'm surprised you haven't reached the limit of your 200W PS yet.
 
hi

i got the new drive. and it seems to be working fine.

i checked on dell's site. it seems that dell uses mean power rating and not
peak, so it seems that my setup should work properly.

thanks for all ur help
