According to hardwaresecrets HX650 is Seasonic G-650, but with "different internal design".
What does it mean?
I think, they have different fans...
Yes, 2xPCIe on Corsair is worse, but with molex reductions I can solve it, I'm not planning SLI in these days...
Will you rather choose Seasonic despite the 7 years Corsair warranty?
Hardwaresecrets was comparing the HX850v2 with the HX650/G650. The HX850v2 is a Channel Well Tech build PSU based on the PUQ-G platform, while the HX650v2 is a Seasonic G 650w internally. Therefore, the HX850v2 is a different design than the HX650v2 and G 650.
IMO, since you are buying a new PSU, rather than going with PSU that will forces you to use molex adapters, get a PSU that have the necessary connectors in the first place. Molex connectors make the setup look rather ugly/messy. Since you aren't going to SLI/CFX, then I guess it doesn't matter, so it's up to you on which on you would want to get. Go for the Corsair if you want a 7 year warranty. But I would have a look at 450/550w solution for your system.
If you in the US and set on getting a 650w unit, you could also have a look at the Rosewill Fortress 650w for $102, btw. There's a non modular Capstone 650w for $64 as well.
