Also need to know how many cd/dvd drives, hard drives, fans, and especially what graphics card your going to use.
Generally now its best to run 480 and up if using a highend card.

256Mb Abit PCI-E RX600Pro Guru Tv/DVI (I'm not a big gamer, if you can recommend a better one up to approx £60 I would be grateful), 1 x CDrom, 1xDVD and 2 x IDE Hard Drives.

350 to 450 will give you plenty to work with without being overkill - lots of wasted power.
Emerex, antec, pc power & cooling are some good power supplies

Your current demand requires the range of at least 400 - 450 W depending on usage.

My recommendation if you replace it do not save $$$ on power supply and go at least with 600W 24 / 20 pin !

Power supply is THE MOST important component of any PC!
In past 10 years on all "branded units" due to desire of higher profits, shoddy calculations to cut the costs the PSU were undersized at leat 40%! "You bought ut is yours headaches, not ours".

i.e DELLs with 275 -350 W instead at least 450, and eMachines with 118 W instead of at least 250 W (integrated crap)!

Any PC should have at least 25-30% oversized PSU, for any future expanssions and specially now with video cards breaking 50 W.

look at this like this:

standard stuff (MoBo +) 50 W
CPU 100 W - 110 W
Hard disk 25 W - 40 W each
Video 50 W or actual
Audio 40 W or actual
RAM 20 W for each GB
PCI cards 5 W each
multi USB / 1394 provide at least 25 W (say 5 - 6 devices)
DVDRW/CDRW 30 W each

than multiply it x 1.25 - 1.3
