The MEG Ai1300P PCIE5 from MSI is the first ATX 3.0 power supply in the world to be fully compatible. This device can tolerate surges of 2,600W power and is made for next-generation GPUs that consume a lot of power.

The most recent power supply standard from Intel is ATX 3.0, which was finalized back in February. The brand-new 16-pin 12VHPWR power connection, which permits up to 600W of power consumption from a single cable, is supported by the new standard, which is notable. Additionally, ATX 3.0 adds a variety of new power requirements with increased power spike tolerance and enhanced efficiency and reliability ratings.

In comparison to earlier designs, MSI’s new MEG Ai1300P PCIE5 has higher quality components. The device, according to MSI, can manage up to twice as much power, or 2,600W, and is made to withstand the significant power fluctuations anticipated with next-generation GPU technology.

On Nvidia’s most recent RTX 30 series GPUs, power spike issues are already problematic; according to Gamers Nexus, the RTX 3090 and RTX 3090 Ti may experience power spikes as high as 660W, while the RTX 3080 can experience spikes of up to 530W.

Power supplies used today are made to withstand transient power surges over their rated power limits. However, these surges have become an issue with the 30 series GPUs to the point that certain units will turn off owing to overprotection restrictions (rarely, but it does happen from time to time). Furthermore, given that next-generation GPUs are expected to virtually quadruple current-generation GPUs’ power consumption ratings, it’s reasonable to predict that their power spikes will be at least as terrible as current-generation GPUs’.

The largest power surge that the new power supply can withstand is 2,600W, and it can only withstand such a spike for a fraction of a second. The device can withstand a 2,340W power surge for 1ms, a 2,080W power spike for 10ms, and a 1,560W power spike for 100ms, however this time rises significantly with lesser power spikes.

The first and only power supply that completely conforms with the ATX 3.0 standard is MSI’s MEG Ai1300P PCIE5. However, as the launch of Nvidia’s 40 series and AMD’s Radeon RX 7000 series GPUs approaches, more ATX 3.0-compliant devices ought to be on the market shortly.
