MSI Preps PCIe Gen 5 Power Supply with Support for 600W GPUs vis-à-vis RTX 4080/4090

MSI is prepping its next-generation power supplies for launch armed with support for NVIDIA’s Lovelace GPUs. Capable of delivering up to 600W of power to PCIe Gen 5.0 graphics cards, this PSU comes with a native 16-pin PCIe connector, also known as the 12VHPWR. This is the default connector for the RTX 3090 Ti, albeit an adapter allows the use of two standard 8-pin connectors as well.

Both the RTX 40 and the Radeon RX 7000 series should work with contemporary power supplies but using a single connector instead of two always looks cleaner. MSI is planning to release two high-end power supplies under the MEG family, namely the Ai1300P and the Ai1000P.

These are both PCIe Gen 5 compatible PSUs, capable of delivering non-stop 600W of power to dGPUs via a single 12-pin power connector. MSI also boasts 2x total power excursion and 3x GPU power excursion with its new ATX 3.0-ready units.

This refers to the ability to handle spikes in power draw due to sudden bursts in load, something that was an issue with the RTX 3080 Ti, 3090, and the 3090 Ti. These new power supplies will be able to supply up to 1200W of power to the GPU and over 2000W to the entire system, momentarily (if needed) to prevent crashes and stutters.

Last but not the least, MSI’s real-time monitor (GI) will allow tracking of the output voltage and load of various railings and, of course, the fan speed.
