It is, the HX650 which is almost identical to the HX620 and TX650 (slide slightly higher efficiency due to a small design tweak) only peaks at 42mv on the 12v rail. Like wise, the PC Power & Cooling Silencer 610w had similar results only peaking (at worst) at 47mv.

Jonny's test was much more unrealistic; even for a load pattern of the time. It'd be more considered a crossload by today's testing.

Right now, the best performing unit we've seen is from Super Flower. To be honest though; that's only one unit of a whole series. but they have a higher wattage platinum unit in the works as well.

Seasonic's M12D platform performs on par with the Super Flower except that it's just ever so slightly less efficient. They even showed they could learn from those soldering mistakes in a short period of time when they partnered with XFX for the Black Edition PSU's.

There's also the Channel Well Tech DSG Platform used in the Corsair HX850.

Antec is even in the game when they made the Signature 850w with Delta or their new "king" the Antec High Current Pro 1200w

There's the Enermax Revolution 1050w.

Plenty of exceptional units from 5 different OEM's; but none of them are really the king.

Based purely on performance and build quality I'd have to choose Delta because no OEM can compete with their automated assembly lines.

Right now though; plenty of OEM's do great work. CWT, Seasonic, Super Flower, Delta, & Enermax can all be considered on par with one another.

Antec warranty has been good to me. Just as good as Corsair in my experience.

Tx-650 vs. TPN-650: Either will be okay.

Tx-750 vs. TPN-750: The Antec costs less and performs better with the same warranty length (5 years). No reason to be a Corsair fanboy for this model.

Tx-750 V2 is better than older Tx-750 "V1." However, the Tx-750 V2 costs about $120 now.

Get the Antec TPN-750 model because it is only $5 more in the USA. You don't have to worry about adapters and it is "overkill" for 2x5850's.

TX650 or TX650-C vs TPN-650 is an easy win for Antec.

For that matter, any True Power New unit vs Corsair's Enthusiast Series (TX & VX) is a clear win for Antec because of the price and features, combined with the performance of them.

Though all of Corsair's TX v2 units perform admirably.
