Default Power Supply, Enough juice?

I used the power supply calculator and it came out to be 297 watts. I'm going to use an Athlon XP Barton 2500+ and overclock it to 3200+ speeds. This case that I really like comes with a 380w power supply, so would it be sufficent for the overclocking? I said the processor was a Barton 3000+ when I used the calculator. This can save me some money in the long run and I guess I could upgrade the power supply later if I had to.

My Rig
- Antec Sonata Case w/ 460w Enermax Whisper II PSU
- Abit NF7-M Motherboard
- AMD XP 2500+ Barton w/ Thermaltake Silentboost HS/F
- 1GB PC3200 Corsair XMS Series
- Geforce 6800
- 80GB Western Digital Special Edition
- NEC DVD+-RW Drive
- Windows XP Pro

there are better cases with more power and 4 or 5 fans available at that site for less than this case.
I wish I had a computer but I am broke!!!

it`s gonna be cutting it close. I had a 380 watt (not overclocking) and I exchanged it for a 480 watt just to be safe and future proof.

The wattage of a power supply is only ONE aspect. Generic power supplies that come with cases are generally very low grade when it comes to providing enough juice on the +12v rail. Generally only 10-15 Amps. To be on the safe side, what with overclocking and all, i would consider getting an Antec TruePower power supply (330W would prolly do). and swapping it with the generic power supply on your case.

It doesnt matter if a power supply is 500Watts. If it doesnt have enough Current capacity on the seperate rails, then theres a good chance itll have a short life, and when it goes it could take your system with it...better safe than sorry
