Corsair HX850 and HX750 Professional Series Power Supplies
Corsair may be best known for its high-performance memory products, but its line of power supplies has also garnered a reputation for solid and reliable performance among enthusiasts. Now Corsair is adding to its Professional Series lineup with the addition of the HX850W and HX750W power supplies. Both of these units are certified 80 Plus Silver and achieved 90% energy-efficiency at 50% load and 230V AC input. The higher efficiency translates into less wasted energy being generated as heat which means the temperature controlled 140mm fan can run at lower speeds and produce less noise. Both units feature a single 12V rail design enabling them to deliver up to 99% of their total wattage on the +12V rail and are at an ambient temperature of 50°C. Along with the standard 24-pin ATX connector, the HX850W and HX750W have 10 modular cable connections with 2 EPS/ATX12V 8-4 pin, 4 PCI-E 6+2 pin, 12 SATA and 8 4-pin connections. With active PFC and a power factor of .99, 105°C solid state capacitors and a 7-year warranty it's no wonder these units have already managed to land outstanding reviews. Both units are available immediately and the HX850 can be found online for around $200US.
