HD power usage

Hello /comp/.

My PC has 4 Hard Drives, and 1 Tb of storage space - all that anime, games and porn takes up lots of space. Because I am starting ot run out of space again, I am planning to buy a new HD - I don't really like backing up to DVD, you see.

What I am worried about is whether my PSU will be enough to run 5 Hard Drives as well as a fairly modern gaming rig - its a 450 watt PSU, and I am not sure if this is enough.

Any suggestions? will my PSU be enough, I should I upgrade that too?

OP here - pretend there is not a load of redundant phrases and overly used words in this post.

eBay your hard drives and buy three\four 500gb ones, you fag. It's Black Friday soon, they'll be on sale for $50 somewhere.
