i want to get the intel i5 2500k but my main concern is my psu.It is a antec 450w
i have a radeon 5670 graphics card
1 250gb hard drive
2 sticks of 512mb ram.
is it enough power?if not could someone suggest a different cpu from the I series?
well to me, the PSU should be fine for the system being shown to us.
Although just a note: if you ever plan on upgrading the gpu in the future, more than likely you'll need to upgrade the PSU.
So in my personal option, i would go after maybe a 600W to 700W psu if you do have any upgrade plans in the future. If not, the PSU presented to us should be fine.
