Antec HCG850 Pro Platinum ATX 3.1 Power Supply Review

The Antec High Current Gamer series is a bit of a legend in the world of PSUs. I’ve had HCG units that have lasted 10 years without issue, they’ve a reputation for being practically bullet proof in terms of reliability, and with the new HCG850 Pro Platinum ATX 3.1 power supply in the office today, I’m honestly expecting nothing short of excellence from this PSU today. With it certified for ATX 3.1, and PCIe 5.1 standards, and 80 Plus Platinum efficiency, it’s obviously a reasonably high-end PSU. While I’m reviewing the 850W unit today, there’s also a 1000W and a 1200W version should you need even more power.

Equipped with 100% high-quality Japanese capacitors, PhaseWave™ Design with a “server-class” full-bridge LLC design, DC-to-DC topology, and a full suite of industrial-grade protections including OCP, OVP, UVP, SCP, OPP, OTP, SIP, and NLO, the HCG Pro is ticking every box we could hope for, so it should deliver some impressive efficiency, stability and low-noise power delivery in our testing. Having had a sneaky peak at these at Computex 2024, I’m eager to get started, so let’s get to it!
