In Win P85 850W Power Supply

The In Win P85 is a new AT type power supply delivering 850 watts of fully modular power. It holds 80 PLUS Gold certification with up to 90 percent conversion efficiency. Smart fan control uses three temperature ranges to adjust speed automatically based on load. A shutdown cooling mode runs the fan for 60 seconds after power-off to clear residual heat.

Ideal for Quiet, Efficient Builds

The smart temperature-controlled fan and flat modular cables suit builders who value low noise and clean cable routing. The 60-second post-shutdown cooling helps systems that retain heat after heavy workloads. Buyers who need a power supply without modular cabling or a different efficiency rating should consider other options.

850W 80 PLUS Gold AT Output

This unit provides a continuous 850 watt output under the AT form factor with 80 PLUS Gold efficiency. That single rating determines whether the PSU meets the power and efficiency requirements of the intended system configuration.
