MSI MEG Ai1300P PCIE5

Product Information

MSI call this ‘G.I' (Gaming Intelligence) support. I can't say I really have had great experiences with the MSI software in the past and sometimes it would crash on the test system I used, but the software for the power supply seems to show everything that MSI claim. MSI outs their PCI Express 5.0 and ATX 3.0 compliant power supply units MEG Ai1300P PCIE5 and MPG A1000G PCIE. In addition to the MEG series, MSI has also introduced its MPG PSU lineup with the latest ATX 3.0 standard. This PSU lineup is designed with core enthusiasts & high-performance gamers in mind. For starters, the PSU is 80 Plus Golde Certified & comes equipped with 100% Japanese capacitors that are rated to run optimally up to 105C. It has an output port that is compliant with PCIe 5.0 and Intel PSDG (Power Supply Design Guide) ATX 3.0, also the power supply can hold up to 2x total power excursion and 3x GPU power excursion.

The unit achieved 80 Plus Titanium hitting just over 94% efficiency around 50% load falling to around 92% efficiency at a full load situation.Press Release: MSI welcomes the MEG Ai1300P PCIE5 power supply unit, the world’s first power supply unit to be fully ready for ATX 3.0 and PCIe 5.0. With graphics cards becoming all the more important, users must know what components to buy for their system if they are looking to upgrade. To understand why the MEG Ai1300P PCIE5 is the ultimate future-proof power supply unit, let’s begin with understanding ATX 3.0. What is ATX 3.0? Both power supply units are designed with the installation process in mind. Both the MEG Ai1300P PCIE and the MPG A1000G PCIE5 are smaller than typical PSUs on the market within their tier, making them an excellent fit for most PC cases. Their fully modular design means that only the connectors required by the build need to be used. This can significantly reduce cable clutter and simplify the system's overall build. In light of the new ATX 3.0 standard, we took a shot at adding power excursion compliance testing into our articles. Given that this is the big addition to the ATX 3.0 specification– and indeed its very reason for being – it’s where we would like to see if PSUs are truly living up to the very high standards set by the new specification. Just under a year since the specification was first announced, the ATX 3.0 era for power supplies is now underway. The updated version of the Intel-maintained specification introduced several notable changes to PC power supply designs, most notably the introduction of the 600 Watt-capable 12VHPWR connector and associated cabling. Altogether, ATX 3.0 is designed to lay the groundwork for future video cards (and other high-powered accelerators) by providing for a single-cable power connection that can better accommodate the high total and rapid shifts in power consumption a video card can undergo.

With graphics cards becoming all the more important, users must know what components to buy for their system if they are looking to upgrade. To understand why the MEG Ai1300P PCIE5 is the ultimate future-proof power supply unit, let's begin with understanding ATX 3.0. The ATX 3.0 standard is still fairly new for power supplies, and we've only seen a handful be released to the general public. For SilverStone, we've got the SilverStone HELA R series. It's fairly similar to this MSI PSU in terms of available power for delivery and specs. Other brands have also launched their own units, including ASUS and Thermaltake.

Despite the exceptional resilience of the PSU against high ambient temperatures and its 80Plus Platinum efficiency levels, the losses of a unit this powerful sum up to over 100 Watts under high loads. These losses do increase the internal temperature of the PSU significantly but the cooling system of the MSI MEG Ai1300P PCIE5 proves to be more than adequate, as the temperature of the critical components does not get anywhere near critical levels during our testing. As a matter of fact, the MSI MEG Ai1300P PCIE5 delivers lower temperature figures than many units with significantly larger bodies and fans do.

Nevertheless, we took a shot at testing the power excursion capabilities of the MSI MEG Ai1300P PCIE and of thefew ATX 3.0 compliant units that we currently have available. We took two approaches:one by assuming that our electronic loads are “ideal” and programmed the exact duty cycle figures that Intel dictates in their guide, and one by trying to take into account the real slew rate times of our loads and calculate the RMS equivalent duty cycle. The efficiency of the MSI MEG Ai1300P does meet the 80Plus Platinum certification requirements when it is powered from an 115 VAC source. However, when the main’s voltage is 230 VAC, the efficiency is raised by an average of 1%, which is not enough to meet the 80Plus Platinum requirements for that input voltage. The average nominal load efficiency (20% to 100% of the unit's capacity) is 92.1% with the unit powered from a 230 VAC source, and drops down to 91.3% if the unit is powered by a 115 VAC source. It is also interesting to note that itsefficiency under very low loads is quite high, at above 83% for a 5% load. It is important to keep in mind that some power supply units may find a way around the power spikes by lifting 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 Electronic circuitry aside, the platform that the MEG Ai1300P is based upon is quite standard and proven. The filtering stage begins on the rear of the AC switch, with six Y capacitors, two X capacitors, and two filtering inductors. It is more than what specifications require but not overly large for such a design. The filtering stage leads to two large rectifying bridges, which are placed on their own heatsink.

The MSI MEG Ai1300P offers 1300W of power while the MEG Ai1000P is a 1000W unit. The MEG Ai1300P offers 1300W of sustained power through its +12V rails at 108.33A. Its voltage is rated between 200-240V (50~60Hz). Now the most interesting part about both of these PSUs is the G.I. (Gaming Intelligence). The new G.I. is based on an MPU, a smart processor, that controls the whole AI-assisted process of the PSU. Some of the main features that the G.I. engine provides through the MSI Center application include: What we tested is also an extremely unlikely scenario for the moment, as no graphics card can currently be drawing 600 Watts constantly – it would itself melt. Even by taking the massive 3× power excursions into account, the average power drawof any cardover practical lengths of timeis significantly lower than 600 Watts – therefore, the cable should never reach temperatures that may become a concern. For the testing of PSUs, we are using high precision electronic loads with a maximum power draw of 2700 Watts, a Rigol DS5042M 40 MHz oscilloscope, an Extech 380803 power analyzer, two high precision UNI-T UT-325 digital thermometers, an Extech HD600 SPL meter, a self-designed hotbox and various other bits and parts. For a thorough explanation of our testing methodology and more details on our equipment, please refer to our How We Test PSUs - 2014 Pipeline post. Both have a +12VHPWR connector and can offer up to 600W of power, making them ideal for the latest GeForce RTX 40 series. The cable is a fully modular system that connects only what is required, and all capacitors are manufactured in Japan. The product has a ten-year warranty. The efficiency of your power supply directly influences your system’s performance and your power consumption. The 80 PLUS Platinum certification promises lower energy consumption and higher efficiency.

What can be more Silent than a ‘GALE' you say? Well yes, I can think of quite a few things! We can only imagine the naming for this product was lost somewhere in translation between Asia and Europe. From 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 meeting all the standards of Intel Testing Requirements at 120%, 160%, and 180% as well. The voltage of MEG Ai1300P PCIE5 can be controlled within the allowable voltage range when the current changes rapidly and violently to maintain the system stability and avoid system abnormalities.
