Fully Modular 850 W ATX Power Supply

The Corsair HX850 CP-9020213-NA is a fully modular ATX power supply rated at 850 W. It is built for systems that need clean power delivery and cable flexibility. Triple EPS12V connectors support modern motherboards and graphics cards. Only the cables required for a build need to be connected.

140 mm Fluid Dynamic Bearing Fan With Zero RPM Mode

A 140 mm fluid dynamic bearing fan runs on a calculated curve for low noise and effective cooling. Zero RPM mode stops the fan completely at low to medium loads for near-silent operation. 80 PLUS Platinum certification delivers up to 92 percent efficiency, reducing heat and power draw. 105°C Japanese capacitors ensure reliable output.

160 mm Length Fits Standard ATX Cases

The unit measures 160 mm in depth, fitting standard ATX case layouts. Fully modular cables include 24-pin ATX, three 8-pin EPS, two 8-pin PCIe, multiple SATA cables and a PATA cable. Cable lengths such as 600 mm and 150 mm for PCIe allow tidy routing. Modern Standby support enables fast wake-from-sleep times.

商品問答

How do I install the fully modular cables, and which step do builders often miss?

Connect the 24-pin ATX cable, the three 8-pin EPS cables and only the PCIe or SATA cables your build needs; the step often missed is seating each modular plug fully into the PSU socket until it clicks.

What maintenance or replacement will the 140 mm fluid dynamic bearing fan need later?

The fan is rated for long life; typical maintenance is occasional dust removal with compressed air, and replacement is only needed if bearing noise appears after many years.

What limit appears first under sustained full load?

The 850 W maximum power rating is the first hard limit; the 80 PLUS Platinum 92 % efficiency and 105 °C Japanese capacitors keep temperatures in check up to that point.
