SilverStone has released a very powerful power supply unit Hela 2500Rz. The new product produces 2500 W, complies with ATX 3.1 and PCIe 5.0 power standards and is equipped with enough connectors to connect four video cards with a 12V-2×6 connector.

The manufacturer first demonstrated the Hela 2500Rz last summer. Since then, it took the company about another year to perfect the power supply and put it on sale. To deliver full power, the device requires connection to a 240 V outlet.
The PSU is powerful enough to power four RTX 5080 (or RTX 4090) graphics cards, or three RTX 5090s. Even more lower-power graphics cards can be connected to it using regular 8-pin connectors—the PSU comes with two dual 6+2-pin power cables, as well as three regular 6+2-pin ones, for a total of seven 8-pin connectors.
The Hela 2500Rz is designed for workstation use. It only comes with one 24-pin power cable, so it’s not suitable for dual-system use. The package includes three SATA cables (four outputs each), four EPS/PCI 8-pin (in a 4+4 pin configuration), one four-pin Molex (with four connectors), as well as the four aforementioned 12V-2×6 cables and four additional regular 8-pin cables for older graphics cards.
The SilverStone Hela 2500Rz power supply unit has a Cybenetics Platinum efficiency certificate (efficiency 89–91%), is equipped with Japanese capacitors, as well as all kinds of protection systems, including 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). The power supply unit has one power line of 3.3 V, 5 V, and 12 V. The first two together provide a power of up to 120 W, the 12 V line – up to 2500 W.
A 135 mm fan is responsible for cooling the power supply components. When the load is less than 10%, the fan does not rotate. When the load increases to 20%, the rotation speed is 500-600 rpm. At 100% load, the fan operates at 2000 rpm. The dimensions of the power supply are 200 × 150 × 86 mm.
The price of the Hela 2500Rz power supply is not disclosed, but it is obvious that it will be one of the most expensive PSUs on the market.
