SilverStone HELA 3000Rz Power Supply Hits $820 for 4-GPU AI Rigs

SilverStone released the HELA 3000Rz power supply, a unit designed to handle the extreme power demands of modern AI workstations. This product addresses a common challenge for builders of multi-GPU systems who need reliable power delivery under heavy loads. The 3000W capacity supports the high power demands typical of DIY AI inference workstations.

New 3000W ATX power supply targets multi-GPU AI inference builders

The HELA 3000Rz operates as an ATX PS/2 unit, a form factor that supports the latest high-density power requirements. SilverStone specifically engineered this supply for DIY AI inference workstations that utilize up to four high-performance GPUs. The power supply is designed for sustained high-power output suitable for continuous workloads.

Specifications

• Form Factor: ATX PS/2
• Continuous Power: 3000W
• Efficiency: 80 Plus Platinum
• 12V-2×6 Connectors: 4 (600W each)
• Max Current: 250A

Technical specifications highlight a robust connector layout to support these multi-GPU configurations. The unit provides four 12V-2×6 ports, each rated for 600W, alongside four 4+4 pin EPS connectors. It also includes eight 6+2 pin PCIe power ports and eight SATA connectors for storage needs. The internal design features a 140mm dual ball bearing fan and supports a maximum current of 250A on the single +12V rail.

Efficiency and power delivery are critical for these high-wattage systems, and the HELA 3000Rz meets 80 Plus Platinum standards at 230V AC. The North American version includes a C19 to NEMA 6-20 power cord, allowing the unit to draw 3.75kVA from a standard wall outlet. The included C19 to NEMA 6-20 power cord allows connection to standard 3.75kVA wall outlets in North America.

The HELA 3000Rz is available in the United States for 819.99 USD (around $820). SilverStone made the unit available for purchase starting on September 1, 2024. We touched on SilverStone Announces HELA 1000Rz and HELA in our earlier Silverstone coverage, which provides context for this higher-wattage expansion of their HELA line.

The HELA 3000Rz is targeted at DIY AI inference workstations requiring support for up to four high-performance GPUs. The unit provides 3000W of continuous power with 80 Plus Platinum efficiency at 230V AC. Builders seeking to assemble multi-GPU AI rigs now have a dedicated power solution that matches their hardware capabilities.
