WEININ K SATA is standard and it should work fine with your iMac PC, however please note that the SATA bandwidth is limited to 3.0Gbps (300MB/s) therefore by installing this drive you will be getting 300MB/s read but not 530MB/s as advertised.

RYAN C Hey there, Yes this drive is fully compatible with the iMac, in fact you can head over to ifixit dot com to get detailed walk-throughs with pictures and sometimes video instructions for how to install this hard drive on your own. It would be very helpful for you to either make Time Machine backups or have your Mac OSX Installation disc handy when you are attempting to get this drive up and running. You can use a free software such as Carbon Copy Cloner to clone your existing OSX installation over to this new drive for free, and after the swap this new one would boot up as normal, however an insane amount faster than your old mechanical hard drive!
