MSI Preps PCIe Gen 5 power supply with support for 600W GPUs vs. RTX 4080/4090

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

The RTX 40 series and Radeon RX 7000 series should work with contemporary power supplies, but using one connector instead of two always seems cleaner. MSI plans to launch two high-end power supplies in the MEG family, namely the Ai1300P and Ai1000P.

They are both PCIe Gen 5 compliant power supplies, capable of supplying 600W of non-stop power to dGPUs through a single 12-pin power connector. MSI also offers 2x total power excursion and 3x GPU power excursion with its new ATX 3.0 compatible units.

This refers to the ability to handle spikes in power consumption due to sudden load spikes, which was an issue with the RTX 3080 Ti, 3090, and 3090 Ti. These new power supplies can provide 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 least, MSI’s Real Time Monitor (GI) will track the output voltage and load of various ramps and, of course, fan speed.
