I'm going to make some changes to my hardware (crossfire HD 4850s) and will definitely need a new PSU. My intended set up is:
Q6000 GO stepping at 3GHz
Asus p5q pro
2 x HD 4850 in Crossfire
Seagate 7200.12 HDD & old Maxtor HDD
I'm thinking a 600W PSU, but I'm not too familiar with PSUs and I'm not sure which brand/model to go for. Would 600W be enough and if so what are the best PSUs at this wattage? Value for money is quite important and less than £80 would be good.
