Is 300w enough?
After my trusted KT133A based mobo died I have gone for an upgrade. My final spec will be:

Abit KX7-333 Mobo
Athlon T-Bird@1.33Ghz, cooled by Zalman Flower Cooler
40Gb Seagate Barracuda IV
Geforce Ti4200 64mb
1 Case Fan
CD Burner, Ye olde PCI 16 Soundblaster and a Network Card

I have a 300W Aopen power supply which is rated at 300W, is this enough to power these components?

Oops LOL.

I should've also said that I'll be using 512mg of PC2100 RAM

I don't know that particular PSU... You need a lot in the 5v line to power a Ti4200. Most people needing more wattage don't realize, it's not the total wattage being stressed, it's usually the 5v line giving out. Getting a brand name high wattage PSU is an easy way to play it safe, but expensive.

Do you have the specs for your PSU?

My brother runs an ECS K7S5A and XP1600+ on an antec 300W. Its not a problem, so I think you will be ok. His voltages are pretty good.

Yes, my specs are:

+3.3V -- 14.0A
+5V -- 30.0A
+12V -- 12.0A
+5vsb -- 0.85A
-5V -- 0.3A
-12 -- 1.0A

The model of the PSU is an Aopen FSP300-60GT

Hope this helps

Can't tell for sure, but the 5v seems a tad on the weak side, and the 3.3v is definitely low compared to other PSU's I've seen.

I doubt you can damage other parts by trying. Try using it in the system after you have upgraded, and if the system seems unstable (especially reboots), keep an eye on your voltage readings. If it falls outside +/- 5%, you'll need something more powerful.

Good luck.

I suggest you get either a 350watt or 400watt PSU. Just to be in the safe side and for future power requirements. I was just reading an article on the new Nvidia Geforce FX vid card and found out that you'll have to have at least a 350watt PSU on your system to ensure stability.

You might wana check out this article on PSUs

Unfortunately, 300W PS's are obsolete for up to date machines. There are a few folks that insist that their XP-2600+ boxes with all the trimmings run fine on a no-name 250W ATX PS.

Never known one of these people! For quality and bang per monetary unit, it's hard to beat a 350W Sparkle. A 400W PS may be a wise investment, new PC's never seem to require less power.

The "shootout" that JayJay's link takes you to is well worth a read.
