SKU CH-VCR2-682N8 MPN HA2500R-PM

A 2500W ATX 3.1 power supply with four native 12V-2x6 connectors for RTX GPUs, Cybenetics Platinum efficiency, a 135mm dual ball bearing fan, and 200mm depth for compact builds

  • ATX 3.1 and PCIe 5 compliance ensures modern GPU support
  • Four native 12V-2x6 connectors power RTX 40/50 series cards
  • Cybenetics Platinum certification delivers high efficiency
  • 135 mm dual ball bearing fan runs silently with delayed shut-off
  • Compact 200 mm depth simplifies system integration

2500W ATX 3.1 power supply

This 2500W ATX 3.1 unit targets AI workstations and multi-GPU builds that demand sustained high output. It delivers continuous power at up to 50°C operating temperature. The Cybenetics Platinum certification confirms high efficiency across typical loads. Builders needing less capacity should consider lower-wattage models.

Four native 12V-2x6 connectors

Four native 12V-2x6 cables are included for direct connection to RTX 40/50 series graphics cards. This covers most multi-GPU configurations without adapters. Systems requiring more than four such connectors will need additional cables or a different power supply. The 12V rail handles the full 2500W rating.

Fully modular 3rd-gen interface and 135mm fan

The fully modular design uses SilverStone’s 3rd generation interface for clean cable routing. A 135mm dual ball bearing fan runs silently and features a delayed shut-off function after power-down. The compact 200mm depth eases installation in standard cases. No software suite or RGB lighting is bundled.

The unit provides four native 12V-2x6 connectors with cables included, each delivering up to 12V power for RTX 40 series graphics cards and other 12V devices within the 2500W total capacity.

How can I verify the PSU is operating correctly after installation?

The Cybenetics Platinum certification confirms high efficiency, and the 135mm dual ball bearing fan with delayed shut-off function provides audible feedback during normal 24/7 operation at up to 50°C.

Which cables come in the box and what must I source separately?

Four 12V-2x6 cables are included for RTX 40/50 series GPUs; the fully modular design with 3rd generation interface means all other cables are detachable and selected per build.
