INTRODUCTION

    Largely thanks to both AMD and NVIDIA power supply unit sales have peaked since last year and for someone who's seen countless people over the years skip on getting a good model watching people now place far more weight on that specific hardware component than ever before is quite satisfying. MSI in particular has done very well with their latest ATX 3.2 & PCIe 5.1 compliant power supply units and today I'll be testing yet another such model of theirs, the latest MPG A1000GS PCIE5.

    MSI is a leading provider of hardware solutions for gaming, content creation, and business productivity. Known for its innovation and reliability, MSI develops products that enhance user experience and improve efficiency in a wide range of applications.

    The AxGS PCIE5 is part of MSI's MPG (MSI Performance Gaming) lineup and is currently available in 3 different output models (850/1000/1250W) all of which are fully modular, ATX 3.1 & PCIe 5.1 compliant and 80 PLUS Gold certified (up to 90% efficiency). The 1000W unit which landed in the lab a while back features two 12V-2x6 power connectors (dual color, 600W), single 6+2 pin PCIe power connector, single strong +12V rail (83.3A) capable of delivering almost 100% of the units’ total power output (999.6W) and a peak power output of no less than 1138W (peak should now be up to around 2.25KW for up to 100ms - once again however this is not something i can test). The AxGS PCIE5 line also sports half bridge LLC topology with DC to DC module design, active PFC, zero fan mode for its 135mm fan (starts spinning after a specific load), embossed jacket modular cables, high-quality server grade Japanese capacitors certified for use up to 105 degrees Celsius and a full array of electrical protections including over-current (OCP), over-voltage (OVP), under-voltage (UVP), short-circuit (SCP), over-temperature (OTP), no-load (NLO), surge and in-rush (SIP), and over-power (OPP). Finally, MSI covers the entire AxGS PCIE5 line with a very generous 10-year limited warranty.
