Power supply Wattage issue

[VenGog]

I have a micro ATX mobo with Celery 600
w/ Onboard Video and Audio disabled.
I have a SoundBlaster live MP3+ sound card,
A 2X2X12 HP CD-Writer+ CDRW,
WD HardDisk, Memory
floppy Drive, kbd and an occasional
SB musical key board that
draws power from the midi/gameport.

This is for purely a professional digital music studio
use.

(some times I need to take this around. I don't like
laptop because it does not have the e-mu synth processor)

Could some one tell me if which 150 WattPowersupply is sufficeient
for the above hardware.

'cause MicroATX case can only house 150 Watts PS
Thanks

Crack your case open and look for label that indicate power consumed in watts the and add up the total watts that each item draws.
