The HELA 1650R Platinum is an ATX 3.1 power supply, which means it incorporates components designed to adhere to the ATX 3.1 specification, which requires power supplies to handle much high peak power draw than those in the ATX 2 generation and faster sleep / wake response. Notably, it also features 2 x PCIe Gen5 12V-2x6 12+4pin connectors. With a maximum output of 1650W, the HELA 1650R Platinum offers an exceptional wattage capacity, making it an ideal choice for providing a steady and reliable flow of power for overclocking or handling power peaks from high-end graphics cards.

The HELA 1650R Platinum is a Cybenetics Platinum efficiency certified ATX (PS2) unit, boasting a relatively compact 180mm total depth. Its fully modular design utilizes SilverStone's 3rd generation modular interface, featuring a notable and innovative characteristica unified EPS/PCIe connector setup. This design streamlines cable management and facilitates easy installation. The power supply is capable of delivering a maximum wattage of 1650W, with 1200W obtainable through its dual 12+4 pin 12V-2x6 connectors. To ensure efficient cooling, the HELA 1650R Platinum is equipped with a 140mm Fluid Dynamic Bearing (FDB) fan. Its also incorporated with a delayed shutoff function that allows the cooling fan to run for a short period of time after shutdown, while also providing protection of system from power surges or fluctuations that may occur during system shutdown helping improve system reliability, protection from component damages and prolonging of its lifespan.
