A Power Supply Built for Extremes
The Silverstone Hela 2500Rz has officially launched, bringing an extraordinary 2500 watts of power to the market. This ATX 3.1 and PCIe 5.0 compliant power supply is specifically engineered for extreme workstation builds that require massive power delivery. With four native 12V-2x6 power connectors, the unit can simultaneously power up to four RTX 5080 graphics cards or three RTX 5090 cards, making it an ideal solution for AI researchers, professional rendering workstations, and enthusiasts pushing hardware to its limits.

Voltage Requirements and Regional Considerations
There's a significant caveat to the Hela 2500Rz's impressive capabilities: it requires a 240-volt outlet to deliver its full potential. This requirement makes the PSU immediately accessible in Europe and many other regions where 240V is standard in households, but creates challenges for users in the United States. Most American homes operate on 110-volt electrical systems, which would limit the PSU to approximately 1,350 watts – just over half its rated capacity. Users in the US would need specialized electrical setups or voltage converters to utilize the full 2500W capability.
Premium Features and Specifications
Beyond its massive wattage, the Hela 2500Rz boasts premium components and features expected from a flagship power supply. It carries a Cybenetics Platinum efficiency certification and is built with high-quality Japanese capacitors. The unit includes comprehensive protection mechanisms: over-current protection (OCP), over-power protection (OPP), over-voltage protection (OVP), short-circuit protection (SCP), under-voltage protection (UVP), and over-temperature protection (OTP).

Cooling and Design Considerations
Cooling such a powerful unit is no small feat, but Silverstone has implemented a 135mm dual ball-bearing fan with intelligent thermal management. The fan remains completely inactive under light loads (below 10% capacity), creating a silent operation during less demanding tasks. As power demands increase, the fan speed gradually ramps up from 500-600 RPM at 20% load to approximately 2000 RPM at full capacity. Despite its immense power, the PSU maintains a relatively compact 200mm depth, making it compatible with most full-sized PC cases.
Connectivity Options
The Hela 2500Rz offers extensive connectivity options beyond its four 12V-2x6 connectors. It includes two dual 6+2-pin cables and three single 6+2-pin cables, providing up to seven additional 8-pin connectors for older hardware. The unit also features one 24-pin ATX power connector, four EPS/PCI 8-pin (4+4-pin) cables, three SATA/peripheral cables with four connectors each, and a single 4-pin Molex cable with four connectors. This comprehensive selection ensures compatibility with virtually any component configuration.
Market Positioning and Availability
While Silverstone has not yet disclosed pricing for the Hela 2500Rz, industry observers expect it to be among the most expensive consumer power supplies available. The specialized nature of the product, targeting professional workstations and extreme enthusiast builds, positions it as a premium offering rather than a mainstream solution. The PSU's ability to run continuously at full capacity in environments up to 50°C further emphasizes its professional-grade design philosophy.
