MSI is World’s First Fully Compliant ATX 3.0 Power Supply: MEG Ai1300P PCIE5. This unit is designed for power-hungry next-generation GPUs and can withstand power spikes of 2,600W.
Finalized in February, ATX 3.0 is Intel’s latest power supply standard. The new standard specifically supports a brand new 16-pin 12VHPWR power connector that allows up to 600W power consumption on a single cable. ATX 3.0 also introduces a number of new power specifications with improved efficiency and reliability ratings and significantly improved immunity to power spikes.
MSI’s new MEG Ai1300P PCIE5 features higher quality components compared to previous designs. MSI says the unit can handle up to twice the power, or 2,600W, and is designed to combat the large power spikes expected in next-generation GPU hardware.
Power spikes are already a concern with Nvidia’s latest RTX 30 series GPUs. gamer nexus.
Today’s power supplies are designed to withstand short power spikes that exceed their rated power specifications. However, on the 30-series GPUs, these spikes became a problem, to the point of causing some units to stall due to overprotection limits (rare, but they do happen occasionally). There are also reports suggesting next-generation GPUs will nearly double the power consumption rating of current generation GPUs, so it’s hard to assume those power spikes will be just as bad, if not worse. There is none.
A power spike of 2,600W is the maximum the new power supply can handle. Less than 1 millisecond can survive such a spike. However, this time increases significantly when power spikes are low. The unit can withstand 2,340W power spikes in 1ms, 2,080W power spikes in 10ms, and 1,560W power spikes in 100ms.
MSI’s MEG Ai1300P PCIE5 is the first and currently only power supply fully compliant with the ATX 3.0 standard. However, with the upcoming release of Nvidia’s 40-series and AMD’s Radeon RX 7000-series GPUs, ATX 3.0 compliant units should hit the market soon.
