I have a 480W PSU attached to my computer and I've got the following attached to it,
- DVD-Writer (NEC)
- DVD-Rom (JLMS)
- CD-Writer (TDK) (all 3 separate drives)
- Creative Sound Blaster Audigy 2
- ATI Radeon X800 AGP 8X
- 2 Front Fans
- 1 Side Case Fan
- 3 Rear Fans
- 1 PSU Fan
- 3.00GHz Intel Pentium 4 Processor with HT
- 1x512MB RAM (Samsung)
- 2x512MB RAM (OCZ with heat spreaders)
- 2 80GB SATA Hard Drives
- 1 40GB IDE Hard Drive
- USB Ports connected to Scanner & Printer, rarely used together though
I have an Intel D875PBZ motherboard and am running Windows XP Home Edition.

My question basically is, am I pushing the PSU beyond it's limit? If so, what should I reduce? Also, next month I'm planning to purchase an external USB 320GB HDD, will this cause problems if I don't change the PSU?
Thanks in advance for the help.

On a low quality PSU you might be pushing it, but if its decent then you should still have plenty power left.

I'm not quite sure. I think it's Alienware, because it's actually an Alienware computer, will be 3 years old in Jan 07 but it's just I've upgraded it quite a bit. So, am I pushing it, or would I be fine purchasing the external hard drive and also be able to add another dvd-writer and internal hard drive if I wanted?
