Minimum power supply for i7 2600k

Its a decent unit and plenty for a standard system but as acer says need other details inc gpu model to confirm.

Without any other information and assuming the only thing you are upgrading is the motherboard and CPU, then no, you do not need to upgrade your PSU.

ACER, thanks for the help. My full spec is as follows:

1 - ASUS 1.3 Slim AV card
1 - 500GB Boot Drive
1 - Barracuda 1.5TB 32MB 3.5" HDD
1 - GeForce GTS250 Graphics Card
6 - GB Corsair Dominator DDR3
Windows 7

500w will be plenty for that setup.   Antec is pretty good, as is this PSU;

500w Corsair

Earthwatts is fine.

You're just fine with the power supply you've got now. If you ever upgrade to have a second GPU or another few drives, it might be worth looking at Corsair 650W PSUs as they're pretty cheap.. but no you're good for now  

how about
