Cabling Arrangement

Corsair gives a relative well thought out list of connectors and cables with the HX850. There are a total of two ATX 4+4, six PCI-E, 12 SATA and 12 Molex connectors available with the inclusion of two adapters to go from Molex to FDD. To utilize the second ATX 4+4 connector, you will have to give up one of your PCI-E connectors and possibly the ability to utilize triple GPU's. Very few should run into this problem though as most will need to have a stronger power supply for a triple video card setup.

Rail distribution is as simple as it gets with a single 12V rail.



A Look Inside

Taking the fan off of the unit, we get a great shot of the inside. There isn't much going on in the way of passive cooling, but it is sufficient. The design of the unit helps fresh air penetrate to all areas of the power supply as it is very open.

A pair of Nippon Chemi-Con caps covers the primary side of the Corsair HX850 850W power supply.

Active cooling comes in the form of the Ong Hua 140mm fan, model HA1425H12B-Z.
