HX850i 850W Platinum ATX Supply
The Corsair HX850i is a fully modular ATX12V and EPS12V power supply rated at 850 W. It carries 80 PLUS Platinum certification and delivers 92% typical efficiency across a 100 to 240 V input range. The unit suits high-end desktop builds that need reliable, efficient power delivery.
Installation and common issues
Full modular cabling lets you connect only the 20+4 pin main, six 6+2 pin PCIe and twelve SATA leads required by the build. A 140 mm thermally controlled fluid dynamic bearing fan keeps noise low at typical loads. The 180 mm depth fits most standard ATX cases, though very compact chassis should be measured first. C-Link monitoring requires a free USB header and the Corsair Link software for voltage and fan control.
Ideal users and alternatives
Enthusiasts running multi-GPU SLI or CrossFire configurations benefit from the single or seven +12 V rail modes and the 40 A per rail capability. Builders who prefer a semi-modular or lower-wattage design for smaller systems may find simpler units more appropriate. The Platinum rating and digital monitoring suit users who value efficiency data and software control.

この商品に関する質問
How do I confirm the HX850i is delivering stable power after installation?
Connect the unit to the Corsair Link software via the C-Link port and monitor the real-time +12V rail voltage and fan speed; both should remain steady under load.
Which cables and accessories ship with the HX850i and what must I source separately?
The box includes the fully modular PSU, all black-sleeved cables for the 20+4-pin motherboard, 6+2-pin PCIe, SATA and peripheral connectors, plus mounting screws and a power cord; no extra cables are required for a standard build.
The specs list both single-rail and seven-rail modes — which should I select for my system?
Use the default single +12V rail mode for most modern builds; switch to the seven-rail configuration only if you need per-rail over-current limits for specific multi-GPU or workstation setups.
