http://tinypic.com/r/300ad8w/6 Here's a pic with all my parts, are these all compatible together? Also last time I built my computer I got a psu that didn't have enough power cords, can't remember what I was short on. Can someone tell me which psu to get that will have enough of the adapters for all the parts? I'm open to suggestions or part replacement if you think it'll make it better for the sameish price.
I'd stay away from the green hard disks for a primary drive. They are ok for a secondary storage drive but are slow and will wear out quick if you use it for your OS drive.
For a PSU a quality 500W unit is enough. Maybe a little more if you plan on overclocking. You just need 1 6-pin PCI-E connector and all the other standard connectors. Any PSU nowadays will have all of that. Stay away from low-quality PSUs though like Cooler Master. Corsair, XFX, Antec, and Seasonic are the better brands to pick from. Usually the Corsair CX Builder series are a good budget option.
