ATX3.1 & PCIe 12V-2x6 Ready

The P250II Series meets the newest generation of Intel’s Power Supply Design Guide (PSDG), ATX 3.1. The PSU includes PCIe 12V-2x6, 16-pin connector with high-quality 16 AWG cable. It delivers up to 600W of power output and is ready for all high-performing graphics cards.

InWin Maximizing Performance Potential Equipped with four native PCIe 12V-2x6 PCB headers and supporting up t

Maximizing Performance Potential

Equipped with four native PCIe 12V-2x6 PCB headers and supporting up to seven PCIe/CPU compatible connectors, the P250II ensures seamless performance and flexibility for workstation-level systems.

Fully Modular Ductile Cables

The P250II feature modular and embossed ductile cables. With their high flexibility and easy bending, cable management becomes straightforward and effortless.

Smart Temperature Control Cooling System

System Load < 20%

System Load > 20%

When ZERO FAN mode is activated, the fan will automatically enter hibernation mode once the system’s load falls below the set threshold, ensuring the PSU’s stability and noise levels. The fan will start rotating when the system’s load exceeds 15% to 25%, depending on the total output variation.

When the system load exceeds 15% to 25%, the fan will automatically maintain optimal cooling. ** The system load varies based on the total output power.

Shut Down after 60 Secs

When the system is shutting down, the fan will continue to operate for 60 seconds to effectively remove residual heat.

The industrial-grade 135 mm dual-ball bearing fan enhances overall performance, maximizes system efficiency while improving product stability and extending lifespan.
