Will my PSU handle a 4th hard disk?

Hi,

I currently have 3 hard disks attached to my computer's psu (antec trupower 550w).

Would my power supply unit be able to handle a 4th?

My system:
Intel C2D [email protected]
Nvidia 7900GS
3 Hard disks
2 x 1GB Ram
2 optical drives

Thanks.

Excellent.

I was just worried that if I added another hard disk I would start to get random reboots, etc.

Its so much cheaper to buy a 2nd 500GB hard disk, rather than replace the existing 500GB hard disk with a 1TB model.

Incidentally, in my system (listed in the original post), what is the maximum amount of hard disks that my PSU should be able to handle?

But if you move to multiple hard disks, with 2 video cards and an overclocked cpu, its quite possible that you will need a 600W+ psu.

Now, a 1000W psu - thats overkill.
