Overview

  • MSI Afterburner 4.6.7 Beta is now available, adding official support for the GeForce RTX 5090 Lightning and new AI-enabled power supplies.
  • The new PSU.dll plugin exposes per‑pin current data on 12VHPWR/12V‑2x6 connectors for MSI MPG Ai1300TS and Ai1600TS models while MEG Ai1x00 units provide rail monitoring without per‑pin readouts.
  • GPU Safeguard+ can trigger alarms, show Afterburner or MSI Center warnings, and automatically load an emergency profile that sets NVIDIA GPUs to 75% power and reduces AMD GPU power by 25%.
  • If a fault persists, supported PSUs sound a buzzer for up to three minutes and then force a protective black screen to prevent potential connector damage.
  • HWINFO’s latest beta mirrors the per‑pin telemetry and abnormal‑current alerts, reflecting an industry response to reports of 16‑pin connector overheating.
