The SilverStone HELA 2500Rz is a flagship-grade 2500W power supply engineered for extreme workstation and multi-GPU PC builds. It achieves Cybenetics Platinum efficiency, meets ATX 3.1 and PCIe 5.0 standards, and delivers reliable 24/7 power output with robust safety features. Thanks to its compact 200mm depth, fully modular cabling, and premium Japanese capacitors, it balances massive power delivery with efficient design and thermal management.

Massive 2500W Capacity & Single-Rail Design

Capable of delivering a full 2500W on a single 12V rail, the HELA 2500Rz is ideal for powering the most demanding components, including multiple high-end GPUs.

Highly Efficient & Standard-Compliant

This power supply is Cybenetics Platinum-certified, delivering over 89–91% efficiency, compliant with the latest ATX 3.1 and PCIe 5.0 power standards for future-ready compatibility.

Advanced, Fully Modular Cabling

Featuring SilverStone’s third-generation modular design and flat, flexible cables, it supports tidy cable management and includes four native 12V-2×6 connectors - ideal for powering modern RTX 40/50 series GPUs.

Ultra-Quiet Despite Power

A 135mm dual ball-bearing fan delivers efficient cooling with a semi-passive mode and a delayed stop feature for minimised noise even at high loads.

Compact Yet Robust Design

Despite its immense power output, the HELA 2500Rz maintains a relatively compact form with a 200mm depth, enabling installation in most full-sized desktop cases.

Built for High-End GPU Workloads

Equipped with four native 12V-2×6 connectors and additional PCIe cables, it can power up to three RTX 5090 or four RTX 5080 graphics cards, making it perfect for AI workstations and GPU-heavy configurations.

Enhanced Safety & Durability Features

Designed for heavy-duty use, the unit includes protections such as OCP, OPP, OVP, UVP, SCP, and OTP, completed with premium Japanese electrolytic capacitors and support for continuous operation up to 50 °C ambient temperature.
