Power Supply Enough?

Hey all,
I just built a new system last year with a 450W power supply (came with the case). Since I built the system I've had to add an additional hard drive and now I'm slightly worried that the PSU I have may not be enough. I haven't had any particular reason to suspect this, I just worry about these things.

Currently I have two DVD-RW drives, a Gigabyte motherboard with an AMD Athlon 64 X2 4200+ dual-core processor, an NVidia GeForce 7600 GT video card, two 1 GB sticks of RAM, two SATA hard drives and one IDE hard drive, a ZIP drive, and a floppy drive, as well as one PCI video capture card. I've used a couple of those online PSU calculators and they seem to suggest that I only need around 380W or so, but I don't know if I really trust those things. So I'm checking here to get an expert opinion. Should I spend some cash and upgrade the PSU? If so, what wattage would you recommend?

Thanks in advance,
Doug
 
I'd be worried about using any none well approved PSU.
Unless the PSU that comes with a case is known to be of decent quality AND is powerful enough, I never use them.

I recommend getting a good 600W 85%+ efficient PSU as it will cope better with future upgrades and the PC will operate in the PSUs efficient power range.
Peace of mind can be bought very cheaply these days, especially with PSUs.
