Corsair's HX and TX-M series of PSUs go after the high end
 

Corsair is showing off two new series of ATX PC power supplies at the Consumer Electronics Show this year. The TX-M series has a semi-modular cable design and 80 Plus Gold certification, and capacities from 550 to 850W. The HX series (arguably a blast from the past) is for PC builders going all-out, with fully modular cables, 80 Plus Platinum efficiency, and power output up to 1200W.
