HX650 was actually pretty much the same as the original TX650 (in fact, TX650 and HX620 were identical aside from the cabling). The HX650 just had a few minor component upgrades that allowed it to hit 80PLUS Bronze, instead of just Standard.
Of course the TX650 is now replaced with the TX650-C, which is a completely different design from CWT, but is comparable to the SeaSonic S12 platform that the original was built on.
The new TXv2 units are a new platform from SeaSonic.
