INTRODUCTION

    The recent announcement of the GeForce RTX 5xxx series of graphics cards by NVIDIA and the release of the top-end 5090 variant has already incentivized many people all over the world to upgrade their systems with more powerful power supply units following the latest ATX 3.1 & PCIe 5.1 industry standards. Thankfully the power supply unit market is not what it was even just a decade ago and so there are plenty of such high-wattage models for people to choose from, most of which will do a great job. Still, just like with everything else in this world not all power supply units are created equal and so I'm very curious to see just how the latest High Current Gamer PRO Platinum 1200W ATX 3.1 model by Antec performs.

    Antec, Inc. is the global leader in high-performance computer components and accessories for the gaming, PC upgrade and Do-It-Yourself markets. Founded in 1986, Antec is recognized as a pioneer in the industry and has maintained its position as a worldwide market leader and international provider of quiet, efficient and innovative products.

The company’s products are sold in more than 40 countries throughout the world.

    The High Current Gamer PRO Platinum 1200W ATX 3.1 (also available in 850/1000W outputs) is the latest addition in a long line of power supply units released by Antec (last time I had an HGC model in the office was 2019) which as its name states follows the latest ATX 3.1 and PCIe v5.1 standards and is 80 PLUS Platinum certified (92% electrical efficiency at 50% load). It also comes ready with a single 12VHPWR (12V-2x6) GPU power connector (600W) and three 8-pin (6+2) GPU power connectors, single powerful +12V rail (100A) capable of delivering 100% of the units’ total power output (1200W) , peak power output of no less than 1343.6W (peak should now be up to 2.69KW for up to 100ms - once again however this is not something I can test),  full bridge LLC design with DC to DC topology (Phasewave design), active PFC, 135mm fluid dynamic bearing fan with zero RPM manager, high-quality Japanese capacitors certified for use up to 105 degrees Celsius, individually sleeved cables and their circuitshield array of electrical protections including over-current (OCP), over-voltage (OVP), under-voltage (UVP), short-circuit (SCP), over-temperature (OTP), over-power (OPP), Surge & Inrush (SIP) and No-load Operation (NLO). Finally Antec covers their HCG PRO Platinum 1200W power supply unit with a 10-year limited warranty.
