MSI MEG Ai1300P and Ai1000P Power Supplies Leaked, Optimized for GPU Power Spikes

MSI is readying a line of high-end “smart” power supplies under the MEG Ai P-series. Some of the most relevant slides from its launch presentation were leaked to the web. courtesy g01d3nm4ng0. The PSUs feature ATX 3.0 and PCI-Express Gen 5.0 readiness, including native PCI-Express 16-pin 12VHPWR connectors that are capable of delivering 600 W of power. The lineup includes two models—the Ai1300P (1300 W), and Ai1000P (1000 W).

A key aspect of these PSUs’ ATX 3.0 specification compliance is their ability to handle power excursions (spikes in load) from GPUs, ranging between 1 to 10 milliseconds in interval. Specifically, these PSUs can handle GPU power excursions that are up to 3x the nameplate load (eg: a GPU with 450 W typical power pulling 1350 W spikes). In some of the older PSUs, excursions are known to trigger the overload protection and shut down the system. The MSI MEG Ai P-series PSUs can handle excursions that are up to 2x the PSU’s nameplate capacity (eg: 2600 W for the 1300 W model); and 3x that of the 16-pin connector (i.e. 1800 W). These spikes typically have a extremely narrow interval, and so they don’t threaten the integrity of the circuits.

Another interesting feature of the MSI MEG Ai P-series is the ability for the user to monitor the various runtime electrical and thermal parameters of the PSU using the Gamer Intelligence app. The PSU interfaces with software via a USB 2.0 connection (internal header). The app lets you monitor load on the various voltage rails, real-time switching efficiency, fan speed, etc. There’s no word on when MSI plans to launch these.
