High-density 2050W ATX power supply

The Silverstone HA2050-PT delivers 2050 watts of continuous power from a compact 180mm deep chassis. It meets Intel ATX12V 2.52 requirements and carries Cybenetics Platinum certification for efficiency between 89% and 91%. A 135mm dual ball bearing fan runs in a semi-fanless mode controlled by an onboard MCU. Fully modular flat black cables simplify cable routing.

Suited for high-output workstations

This unit targets systems that demand sustained 2050W output at up to 50°C ambient temperature. The single 24/20-pin motherboard connector and twelve SATA power connectors support dense drive arrays. Builders who operate on 100–120V mains should note the 1650W limit at that voltage range. Buyers needing more than twelve SATA devices or a longer chassis depth should look elsewhere.

2040W on the 12V rail with 120W for minor rails

The +12V rail provides up to 2040W while the combined +3.3V and +5V rails supply 120W. Input voltage spans 200–240Vrms for full 2050W operation and 103–264Vrms for 1650W operation across 47–63Hz. MTBF is rated at 100000 hours. The 12-pin GPU connector is supported for modern graphics cards.

Questions about this item

Does my case have enough depth for the 180 mm PSU length?

The unit measures 180 mm deep, 150 mm wide and 86 mm high, so verify your case clearance against those dimensions before ordering.

Will the 24-pin motherboard connector work with an ATX12V 2.52 board?

Yes, the PSU supports the Intel ATX12V 2.52 standard and includes a 24/20-pin main connector with a 6-pin sense wire that plugs into the modular interface for tighter regulation.

How can I confirm the semi-fanless mode is active after installation?

At low load the 135 mm dual ball bearing fan stops completely for 0 dBA noise; you will hear it spin up only when the internal MCU decides cooling is needed.
