Silverstone Technology HELA 2050R Platinum 2050W server chassis

SKU CH-B6GT-6291S

Delivers 2050W continuous power with Cybenetics Platinum efficiency and ATX 3.0 support in a compact 180mm depth

  • Chassis styleDesktop
  • ATX 3.0 and PCIe Gen 5 compliance for modern builds
  • Cybenetics Platinum certified 2050W continuous output at 200-240V
  • Three 600W-rated 12VHPWR cables for high-power GPUs
  • 135mm dual-ball bearing fan with semi-fanless MCU for quiet cooling
  • Compact 180mm depth fits dense server deployments

High-wattage ATX 3.0 power supply

The SilverStone HELA 2050R Platinum is a Cybenetics Platinum certified ATX (PS2) unit delivering 2050W continuous output at 200-240V or 1650W at 103-264V. It targets intensive workstations and industrial or scientific applications requiring maximum power density. Fully modular cabling with a third-generation interface simplifies builds in space-constrained server chassis.

Three native 600W 12VHPWR connectors

This unit includes three 600W-rated 12VHPWR cables — two native and one via PCIe adapter — matching the 2050W capacity for multi-GPU configurations. The single specification that decides fit is the 180mm total depth, allowing integration into compact server enclosures where longer units cannot be installed. No other length is offered.

Semi-fanless cooling with dual-ball bearing fan

A 135mm dual-ball bearing fan with built-in MCU enables semi-fanless operation at lower loads, reducing acoustic output during idle or light workloads. Under heavy usage the fan provides active cooling rated for 50°C operating temperature. The bundled cables and modular interface change nothing about thermal behaviour; they only affect cable routing flexibility.
