Unrivaled 2050W Power Delivery
The HELA 2050R is designed for those who refuse to compromise. Capable of delivering a continuous 2050W (on 200V–240V inputs), this PSU can effortlessly drive multiple flagship graphics cards and high-core-count processors simultaneously. Despite its massive output, SilverStone has managed to keep the chassis at a 180mm depth, allowing it to fit into many mid-to-full tower cases that typically struggle with ultra-high-wattage power supplies.
Next-Gen Ready: ATX 3.1 & PCIe 5.1
Stay ahead of hardware evolutions with native support for the latest standards. This unit includes dual native 12V-2x6 connectors on the modular interface and comes with three 12V-2x6 cables. These connectors are specifically designed to handle the instantaneous peak power excursions of modern GPUs, ensuring system stability during intense gaming or heavy computational loads without the risk of connector failure.
Cybenetics Platinum Efficiency & Japanese Quality
Efficiency is critical when managing over 2 kilowatts of power. The HELA 2050R is Cybenetics Platinum certified, guaranteeing up to $91\%$ efficiency to minimize heat waste and energy costs. Internally, the unit is built with 100% Japanese electrolytic capacitors, providing the longevity and reliability required for 24/7 mission-critical operations. The 135mm dual-ball bearing fan ensures high-performance cooling with a significantly longer lifespan than standard sleeve-bearing fans.
Intelligent Semi-Fanless MCU Control
Silence is maintained through a sophisticated Microcontroller Unit (MCU) that manages the fan curve. With the semi-fanless mode engaged via a rear switch, the fan remains completely off during low-to-medium loads, providing a 0 dBA silent experience. As power demands increase, the MCU precisely scales the fan speed to maintain optimal temperatures while keeping acoustic noise to an absolute minimum.
