Do I have Enough Juice?

[gamephile]

Hello wonderful Anandtechies, I've got a question for you, Do I need more Power? As I know some of you won't want to look at my system rig, I'll post everything here.

Processor - 1.2Ghz T-Bird
Mboard - Iwill KK266-R
Hard Drive - IBM 60GXP 40GB
Optical - Toshiba 16x DVD
Optical - Lite On 24x10x40
Disk - Iomega Zip 100 Internal
Disk - Generic Floppy
Video - ATI Radeon 64MB VIVO SE
Sound - Hercules GTXP
Misc. - Firewire card (TI Chipset)
NIC - Netgear FA310TX
Modem - USR 56k
Case - Antec SX830

And most important, An Antec 303XP 300 Watt PS.

Now, my question lies in the fact that I would like to purchase another hard drive(s). Eiether a nice new WD 120GB Special edition, or two 60 or 80 GB drives for a raid. I would be adding the drive(s) while keeping all my other components as I still want the IBM. Is my power supply going to be overextended? My instinct is yes. I guess I should be asking, is it overextended now? Would you suggest getting a 400W or would 350 be enough? I am planning on sticking with Antec because I have the most faith in their ps's. Thanks for your opinions and suggestions.

Oh yeah, almost forgot, I checked my voltages in Sandra -
Voltage - My system
+3.3V - 3.36
+5 - 4.71
+12 - 12.01

Sounds like a nice rig powered by a fine PS. Should be fine

Your 300w Antec PS should be more than enough to power all that stuff.

Thanks for the reply's guys. I am happy that my PS will be able to pump out the power. Another 65 bucks that I can spend on something else.
