Corsair has officially announced its newest PSU addition to the HX series, the 750W and 850W models. Both of these have a modular design, efficiency of up to 90 percent and single +12V rail.
Both new models have flat modular cables, active PFC, support for ATX12V 2.3 and EPS12V 2.91 standards, 140mm bottom placed fan and a single +12V rail design. The more powerful 850W model has 70Amps on its +12V rail while the 750W one will have to make due with 60Amps.
The other difference between these two models is the number of PCI-E 6+2 and 4-pin peripheral connectors. The 750W model has "only" four PCI-Express 6+2-pin connectors while the 850W has two more.
