New power supply, or risk it?

[Abix]

Ive got a P4 2.4 with 512MB of RDRAM on my P4T533. Anyways, Ive got two hard drives hooked up, a cd-burner, and 4 case fans at the moment all running off of my two yearish old Antec 300watt power supply. Its all been running fine and dandy up to this point, however, my Leadtek AGP 6600GT is coming in on Monday. Anyways, I was just wondering yall's opinion on whether or not I should(or will need to) get a better power supply.

I looked it up at 15A. I wouldn't risk it. If you're not hurting for money, I'd just get a new one, like this.

I mean, if you do have an insufficient psu, why risk all the RMA hassle if that fries some of your equipment? It's just time lost.
