I am looking into building a PC. I was wanting to know if the Corsair tx650m would power two gtx 670's in SLI, an i5 2500k OC'd to 4.0GHz on a Corsair H60, a Corsair force 3 120GB SSD, 8GB of 1600mhz RAM, and a 1TB HDD?
It is enough power, but it does not have enough PCIe connectors; you need a PSU with four, the TX650M only has two. You can use it if you're prepared to use adapters, but if you haven't bought it already I would recommend buying one that comes with the necessary connectors.
Rosewill is better than Corsair? Rosewill has a history of offering powersupplies of questionable quality and value. They do make a few that are adequate and a few that are better but overall their quality is inconsistant.
After re-reading my post it doesn't seem like I said that Rosewill was overall better than Corsair, seems like I said that the Capstone-650M is a better unit than the TX650M, which it is. It is also better than the Seasonic SS-650AM.
