Should i buy a new PSU?

[snow patrol]

A couple of days ago, my brand new 1900xtx broke. Red dots everywhere doesn't get into windows. Any way, not too worry too much as i got the RMA no. from ocuk and will be hopefully getting a replacement next week then...

Could the PSU cause the card to bork like that? It was working fine to begin with!

Any way, i got to thinking that perhaps my PSU isn't good enough to power my system. I have an Enermax Noisetaker 485w psu, which is supposedly beefy enough, but i have quite a lot of stuff in my system:

2.65 Ghz dual core (running 1.5 volts)
2 gig Ram
5 x Hard Disks
1 x DVD RW
1 x DD5 Water Pump
3 x 120mm low speed fans
1 x floppy
1 x multi card reader
1 x Fan speed controller
3 x UV Cold Cathode lights
and of couse the 1 x 1900xtx card...


Is it too much? I was considering getting a seasonic 600w to be absolutely safe and future proofed...but 100quid, is it really worth it?? do I need it with my system? Many thanks

There are a number of PSU calculators around, I'd see what they say. Personally with nearly 500w on hand I think you should be OK.

just did a quick one on extremehardware and i think i'm going to have to plump for a seasonic 600w!
