Phanteks PH-P1000GH_WT02 1000 W Platinum power supply

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.
