The new HXi units had their efficiency upgraded compared to the previous HX generation, are fully modular, and compatible with the sleep states Intel's Haswell CPUs introduced. A silent-enough fan of good quality and with a fluid dynamic bearing is used to keep the unit cool, and all available protections including OCP are available in the Corsair Link software. Please note that in its out-of-the-box state, the unit is a single +12V rail unit (according to new info received from Corsair after the review was published the unit has multi +12V rails out-of-the-box however Corsair Link during the first start sees it as a single +12V rail one, due to a software bug). At seven years, the warranty is pretty long, and the price looks decent enough given this unit's digital-monitoring features.

The single +12V rail can deliver the unit's full power alone, and the minor rails are strong too. The 5VSB rail can deliver 3 A, so it's a little stronger than the mean.

We should also mention that enabling multi-rail mode through Corsair Link will also enable Over Current Protection (OCP). According to Corsair, this unit's +12V OCP is set to 40 A on each modular 8-pin connector (for PCIe and EPS connectors), 40 A on the 24-pin ATX connector, and 40 A for all the 6-pin modular SATA and peripheral connectors combined. (note: Corsair informed us that out of the box the unit has multiple +12V rails, although Corsair Link during the first run shows it as a +12V rail one allowing you to enable the multi-rail mode. This is a software bug that will be fixed soon.)

Like every modern 1 kW unit, this one has two EPS and eight PCIe connectors, and all of them are available at the same time. To cover every need, Corsair made sure to equip this unit with plenty of SATA and peripheral connectors. Regarding cable length, the ATX cable is long enough, and one of two EPS cables is actually very long. The distance between SATA connectors will suffice, but we would like to see a bigger gap between peripheral connectors. All connectors except for those of the FDD adapters, which utilize thinner wires since very small amounts of current pass through them, use standard 18AWG gauges.
