Successor to the HX620W, alright.

What are the improvements over the HX620W on this? Warranty? OEM - Seasonic or CWT?

So the improvements include more power (obviously), but specifically more amps on the 12V rail (52A / 624W versus 50A for the 620). It's also 80 Plus Bronze, so higher efficiency, and the fan curve is slightly different, which means it will be quieter at typical load levels. There are also 9 x SATA connectors and 4 x 6+2-pin PCI-E as standard. Warranty is 7 years as it's part of the Professional Series. Our engineering partner for 650 is Seasonic, as it was for the 620.

We know that the HX620W was / is a very well respected PSU, so the HX650W retains essentially the same elements that made 620W popular, but adds better performance and features.
