Designed for Workstations and Servers
Designed for extreme computing environments, the HELA 3000Rz provides a massive 3000W continuous power output through a single +12V rail capable of delivering up to 250A. Despite its immense capacity, the unit measures just 200mm in depth, making integration into compatible high-end chassis more manageable than expected.
The power supply is equipped with four native 12V-2x6 connectors, allowing users to power multiple next-generation graphics cards without adapters. In addition, it offers four 8-pin EPS connectors, seven PCIe 6+2-pin connectors, eight SATA connectors, and four peripheral connectors for workstation and server-class hardware configurations.
Industrial-Grade Cooling
Cooling duties are handled by a 140mm dual ball bearing fan featuring a three-phase, twelve-pole motor and copper rivet reinforcement. This design improves precision, durability, and cooling efficiency while maintaining low acoustic performance, with a minimum rated noise level of just 18 dBA.
Comprehensive Protection
To safeguard high-value hardware, the SilverStone HELA 3000Rz incorporates a full suite of protection mechanisms including Over Current Protection (OCP), Over Power Protection (OPP), Over Voltage Protection (OVP), Short Circuit Protection (SCP), and Over Temperature Protection (OTP).
