High-Wattage ATX 3.0 Supply

The Silverstone HA2050R-PM delivers 2050 W through a single +12 V rail rated at 170 A. It meets ATX 3.0 and PCIe 5.0 requirements and carries 80 PLUS Platinum certification for 89 % to 91 % typical efficiency. A 135 mm dual-ball bearing fan is controlled by an MCU for quiet idle operation and full cooling under load.

Multi-GPU And Workstation Builds

The unit suits systems that need three 12VHPWR connectors and up to fourteen 8-pin PCIe plugs for multiple high-end graphics cards. It also provides two EPS connectors and twelve SATA connectors for dense storage arrays. Builds running on 200 V to 240 V mains only should look elsewhere, as the input range starts at 200 V.

180 mm Chassis Depth

The power supply is 180 mm long, so the case must accept at least that depth for a proper fit. This single dimension decides whether the HA2050R-PM can be installed in a given enclosure.

Fragen zu diesem Artikel

How do I decide between the available configurations for this 2050 W unit?

The HA2050R-PM is sold as a single 2050 W model with full modular cabling; choose it when your build needs up to 170 A on the +12 V rail and multiple 12VHPWR connectors for high-end GPUs.

What does the 2050 W rating mean once the PSU is installed in a system?

It can deliver a combined 2050 W across all rails, with 170 A available on the single +12 V rail, 25 A on +3.3 V, 22 A on +5 V, 3.0 A on +5 VSB and 0.3 A on -12 V.

Which ATX standard does the 12VHPWR connector follow and what power limit does it support?

The three 12+4-pin 12VHPWR connectors comply with the ATX 3.0 and PCIe 5.0 specifications, each rated for the higher power delivery those standards define.
