Specifications

This unit is Platinum certified and can deliver its full power continuously at up to an operating temperature of 50°C. The higher the operating temperature, the more the components are stressed. To separate really good PSUs from the rest, you will have to test such units by applying their maximum load at ambient temperature somewhere in-between 45°C -50°C. Not only should the unit survive as such PSUs should also perform as expected.

Corsair or, to be more precise, CWT who actually built this unit, provided it with a full set of protection features. The unit has also been equipped with a high-quality FDB fan to keep it cool. The latter not only operates silently, but lasts a very long time. The unit is a little larger than the standard, but every normal ATX chassis will still accommodate it without any problems. At seven years, the warranty is also incredibly long, and Corsair is known for their excellent support, while the asking price is a little higher than expected for even this product's feature set. Corsair will probably lower its price tag in the near future.

Although the table above lists the unit's power specifications in single +12V-rail mode, the HX750i is by default set to operate in multi +12V-rail mode. According to Corsair's reviewer guide, every HXi's +12V OCP is set to 40 A on each 8-pin PCIe or CPU power connector, and to 40 A on the 24-pin ATX connector. The 6-pin modular peripheral connectors are set to 40 A combined. The Corsair Link software also allows you to toogle the OCP on the 8-pin modular connectors on/off.

Cables & Connectors, Power Distribution

There are a large number of available connectors, with the latter installed on long cables, so you won't have to worry about compatibility problems with even large full-tower cases. Corsair did pretty well; however, the distance between peripheral connectors should be larger since devices that use these connectors are usually installed further apart from one another (e.g.: case fans). The Corsair Link cables, on the hand, are incredibly long, so routing these properly won't be a problem. All connectors except for the floppy ones use 18AWG gauges.
