Model PH-P1000GH_WT02

  • ATX 3.1 platform with PCIe 5.1 support for next-gen GPUs
  • 80 PLUS Platinum efficiency saves energy and reduces heat
  • 120 mm fluid dynamic bearing fan with zero-RPM mode under 40 % load
  • Fully modular individual textured cables and combs simplify cable management
  • 12V-2x6 GPU cable delivers up to 600 W through a single connector

Purpose-built power for high-output builds

This 1000 W unit targets enthusiasts assembling systems that draw sustained power near the top of the ATX range. It suits workstations and gaming rigs with a single flagship graphics card and a high-core-count processor. Builders who need less headroom or lack a PCIe 5.1 GPU should consider lower-wattage alternatives.

Steady delivery under continuous demand

Platinum-rated efficiency keeps waste heat low when the load sits at 80 percent for hours, and the 120 mm fluid-dynamic-bearing fan stays at 0 RPM until output passes 40 percent. Above that threshold the fan spins up gradually, maintaining stable voltages across the 12 V rail without thermal throttling. All protections — OPP, OVP, UVP, SCP, OCP, OTP, no-load and reset — remain active throughout.

Replaces older ATX 2.x units when the GPU changes

The 12V-2x6 connector supplies up to 600 W through one cable, removing the adapter chain required by earlier designs. A swap makes sense when moving to a PCIe 5.1 graphics card or when a fully modular, individually sleeved cable set will simplify a compact 140 mm deep chassis. If the current GPU still uses 8-pin power and the case fits a standard depth supply, the upgrade can wait.

Questions about this item

How loud is the 120 mm fan when the system runs all day at typical load?

The 120 mm fluid-dynamic-bearing fan stays at 0 RPM until the unit passes 40 % load, so it is silent during light work and only spins up when power draw climbs higher.

Which connectors must my motherboard and graphics card already provide for this unit to work?

Your motherboard needs a standard 24-pin ATX socket plus an 8-pin EPS connector, and your graphics card must accept the 12V-2x6 PCIe 5.1 plug that delivers up to 600 W on a single cable.

Will the 140 mm deep casing and ATX 3.1 pin-out fit the older tower and drives I plan to keep?

The 140 mm depth matches the compact ATX form factor, and the ATX 3.1 platform remains backward-compatible with earlier ATX motherboards and peripherals you already own.
