SilverStone has detailed the Hela 3000Rz, a 3000W, 80 Plus Platinum-rated power supply built for multi-GPU AI inferencing and workstation builds, offering four 12V-2x6 connectors and a single +12V rail rated at 250A. It's priced at $819.99 USD in the US market.
SilverStone has officially detailed the Hela 3000Rz, a high-wattage power supply first shown at Computex earlier this year. According to TechPowerUp, the unit is aimed squarely at DIY AI inferencing workstation builds running four high-end GPUs, delivering 3000W of continuous power through a single +12V rail rated at 250A. The PSU carries an 80 Plus Platinum efficiency rating at 230V AC and uses active PFC alongside standard protections including OCP, OVP, OPP, SCP, and OTP, as reported by KitGuru.
Connectivity is built around heavy multi-GPU setups: the Hela 3000Rz ships with four 12V-2x6 connectors rated at 600W each, eight PCIe 6+2 connectors, four EPS 4+4 cables, and a single 24-pin ATX main lead. For storage, it also includes eight SATA connectors and, notably, four legacy Molex plugs. Cooling comes from a 140mm twelve-pole fan with double ball bearings that KitGuru notes spins at around 400rpm under light load and ramps up to nearly 3000rpm at maximum output — a design SilverStone says prioritizes 24/7 stability over silent operation.
The unit weighs 4.57kg, reflecting its dense internals and larger footprint. KitGuru points out that regional power cords matter here: a UK 13A cable caps output at 2600W, while a higher-current cord is needed to unlock the full 3000W. TechPowerUp reports the North American version ships with a C19 to NEMA 6-20 cord capable of drawing 3.75 kVA from the wall, and the PSU is priced at $819.99 USD in the US market.
