The MSI MEG Ai1300P PCIE5 is the world’s first ATX 3.0 compatible PSU with 600W PCIe connector

MSI welcomes the MEG Ai1300P PCIE5 power supply, the world’s first power supply that is fully ATX 3.0 and PCIe 5.0 ready. As graphics cards become more and more important, users need to know which components to buy for their system if they want to upgrade. To understand why the MEG Ai1300P PCIE5 is the ultimate future-proof power supply, let’s start by understanding ATX 3.0.

ATX 3.0 is Intel’s new specification standard for existing PSUs. In short, the main purpose of ATX 3.0 is to provide more reliability, better power efficiency and to provide graphics cards up to 600 watts of power. ATX 3.0 was created in response to the performance improvement of graphics cards and the increasing need for power. ATX 3.0 places great emphasis on power expansions to ensure that powerful graphics cards can be sustained and your system stable. Thanks to ATX 3.0, there is now an increase in idling efficiency and a new power connector has been added to help achieve all of the above. ATX 3.0 has added a new PCIe 5.0 12VHPWR connector with 12+4 pins instead of the traditional 6 or 8. With the new PCIe 5.0 connector, the power supply and cable can deliver up to 600 watts of power.

Fully ready for PCIe 5.0 and ATX 3.0
Many power supplies currently on the market do not yet fully support ATX 3.0. Many require an adapter that connects the three or four 8-pin PCIe connectors to the single PCIe 5.0 12VHPWR connector. It is also a challenge to figure out where to connect the adapters. MSI’s MEG Ai1300P PCIE5 power supplies are fully compatible with PCIe 5.0 and ATX 3.0. With a native 16-pin (12VHPWR) PCIe connector, the MEG Ai1300P PCIE5 is ready for all high-end graphics cards of the future. It can freely route up to 600W of power to PCIe 5.0 graphics cards. To withstand higher currents required by the graphics cards or CPU, the connectors of the MEG Ai1300P PCIE5 power supplies use copper alloy terminals for enhanced safety.

Everything is legit and backed by testing
According to PCI-SIG, graphics cards can exceed their maximum power by 3 times. This is especially true for high-performance graphics cards like the NVIDIA GeForce RTX 3090 Ti or the upcoming NVIDIA next-gen graphics cards. It is believed that the upcoming graphics cards will require 600W of power and will have power expansions up to 1800W. The power excursions last only 100 microseconds, but can already severely disrupt the computer system. Power excursions are also referred to as power spikes by many people.

Intel test requirements

MEG Ai1300P PCIE5 Test Result
In the chart below, you can see that the MEG Ai1300P PCIE5 can safely achieve 2x total power excursion at 200% of the PSU wattage, while also meeting all the standards of Intel testing requirements at 120%, 160% and 180%. The voltage of the MEG Ai1300P PCIE5 can be controlled within the allowable voltage range when the current changes rapidly and violently to maintain system stability and prevent system drift.

Maintain OPP and OCP for maximum safety
It is important to keep in mind that some power supplies can find a way to bypass the power surges by raising the threshold for OPP and OCP. This is not the case for the MEG Ai1300P PCIE5. As shown in the chart below, the MEG Ai1300P PCIE5 maintains the OPP level of 1300W x 1.25 at 1623.55W.

Power Supply Timing Values ​​Is A Pass
In order to be fully compatible with ATX 3.0, there is also a timing value that the power supply must meet. The MEG Ai1300P PCIE5 fully complies with that timing value, as shown in the table below.

With future high-performance graphics cards slowly approaching us, it’s all the more important for users to be prepared if they expect to upgrade their systems. The MEG Ai1300P PCIE5 is the perfect power supply for users who want to upgrade to high-quality components due to its full ATX 3.0 and PCIe 5.0 compliance.
