Time to upgrade - new PSU needed?

[Cerzi]

So I'm currently planning a new build, along the lines of this:

But am debating whether I should get a new PSU. My current one is an Enermax Noisetaker 600W, which is probably already borderline insufficient considering I have 6 hard drives. Also, it's over 4 years old.

How much wattage do you kind folk think I'd need if I do this upgrade? The 480 is supposedly rather power hungry, but presumably still less so than 470 SLIs? Am I maybe better off getting a gtx 5xx?

Thanks!

Thanks guys - agreed that 4 years is getting on a bit, probably worth replacing it now while I'm in a money-spending mood

The PC will be used primarily for gaming, as well as programming (but nothing too heavyweight) - cheers for the tip on the i5 2500k, I think I'll take it. I always get the feeling I need more memory though, I've been using 4gigs for the last couple of upgrades, and my physical memory usage is always up in the 80%+ region, and with the amount I like to multitask surely 8gigs is worth it?

I've been pondering which gfx card to get for a while now, but the deal on the 480 is indeed too tasty to pass up. My other consideration was getting 2x 470s (under 300 quid with that other awesome deal), but getting a 2nd 480 further down the line sounds like a better idea. And no way am I splashing out for a 580.

Good point, didn't think about that one.
