White fully modular ATX power supply with GaN transistors and Equalizer cables

ASUS

ASUS ROG STRIX 1000W Snow Edition Platinum Equalizer Cable power supply

SKU CH-21RZ-Y7VSH

A 1000 W Platinum supply with GaN transistors, Equalizer current-balance cables and ATX 3.1 support for PCIe 5.1 graphics cards

  • Balanced current delivery with ROG Equalizer cables cuts connector heat
  • GaN transistors lower heat output for stable high-efficiency operation
  • GPU-FIRST voltage sensing keeps graphics power steady under load
  • 1224 W peak capacity — 104 % above reference spec
  • Cybenetics Lambda A+ rating for quiet running

ASUS ROG STRIX 1000W Snow Edition Platinum

The ASUS ROG STRIX 1000W Snow Edition Platinum is a 1000W ATX 3.1 power supply built with GaN transistors and 80 PLUS Platinum certification. It includes the ROG Equalizer Current Balance Cable for improved current distribution and lower connector temperatures. The unit is fully modular and supports PCIe 5.1 graphics cards.

Suits high-end GPU builds needing stable 12V

This unit suits builders running PCIe 5.1 graphics cards that demand reliable 12V-2x6 power with reduced cable heat under heavy load. The GaN design and Cybenetics Lambda A+ rating also appeal to users prioritising efficiency and low noise. It is not for systems that cannot accommodate a full-size ATX power supply or builders who need a lower wattage unit for compact cases.

1000W capacity with ATX 3.1 and PCIe 5.1 support

The 1000W rating combined with ATX 3.1 compliance and PCIe 5.1 connector support is the specification that decides compatibility. The ROG Equalizer cable allows up to 1224W peak delivery on the 12V rail while keeping connector temperatures below 105°C. Verify your graphics card uses the 12V-2x6 interface and that your case fits a standard ATX PSU.

Questions about this item

Does this 1000W unit include the 12V-2x6 cable needed for a PCIe 5.1 graphics card?

Yes, the ROG Equalizer current-balance cable is supplied and rated for the 12V-2x6 connector used by PCIe 5.1 GPUs.

Will the Platinum efficiency and GaN design still benefit a system that keeps an older ATX 2.x motherboard?

The supply follows ATX 3.1 and remains fully backward-compatible with ATX 2.x boards while delivering 80PLUS Platinum efficiency and lower heat from GaN transistors.

How can I verify the Equalizer cables are balancing load correctly after installation?

Under a 600W GPU load the connector temperature stays below the 105°C material limit, confirming balanced current distribution across the four +12V wires.
