We feel this design is going to split opinion. The Asian community tend to love gold accented tech products, the European audience, not so much. It is nicely finished, but I am not a fan of the gold touches. Finance is only available to permanent UK residents aged >18, subject to status, terms and conditions apply. According to PCI-SIG, graphics cards are capable of exceeding their maximum power by 3 times. This is especially the case for high-performance graphics cards such as the NVIDIA GeForce RTX 3090 Ti or the upcoming NVIDIA next-gen graphics cards. It is believed that the upcoming graphics cards need 600W of power and will have power excursions up to 1800W. The power excursions only last 100 microseconds but can already heavily disrupt the computer system. Power excursions are also known as power spikes by many people. MEG Ai1300P PCIE5 Testing Result Real-Time Power Status Monitor: Through the MSI Center, this power supply helps monitor the real-time status of the percentage of power supplied to GPU and CPU and the total system wattage used. 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:

The other side of the power supply houses the modular connectors. The power supply can support current generation graphics cards, and if you pay attention you can see the +12VHPWR connector top left which means you can also connect up a new Nvidia RTX 4000 series graphics card.

OTP

The passive components of the APFC circuitry are two beefy 400V/680μF APFC capacitors made by Nichicon, followed by two filtering coils. The active APFC components are on the longest heatsink of the unit. Four transistors can be found on their own heatsink and these form the full-bridge inversion topology at the primary side of the unit. The output of the main transformer is connected to six power MOSFETs that generate a single 12V rail. The 3.3V and 5V lines are being generated via the DC-to-DC conversion circuits. All of the secondary capacitors, electrolytic and polymer alike, are made by Rubycon and Nippon Chemi-Con. The MEG Ai1300P PCIE5 marks a lot of milestones for MSI – it is their first ATX 3.0 compliant unit, the world’s first ATX 3.0 compliant unit, and currently their flagship PSU product. Needless to say, the MEG Ai1300P has to meet very high expectations, both by the users and by MSI themselves. As for 70°C being a high temperature for almost 500W power draw, this is not necessarily so, again, very much depending on where the temperature sensor is placed. When you look at some OTP (OverTemperature Protection) test results, often times they're at 100°C-200°C (!) on the heatsink of the 12V rail MOSFETs. On the Ai1000P, we can see OTP triggering at 168°C for example. The MOSFETs bolted onto those heatsinks are rated to provide their full performance at 100°C, so 70°C is nothing for them. The electrolytic capacitors, yes, you want to stay cool, because that will prolong their life. But with 10 years warranty, MSI feel confident about the longevity with how they have set it up.

We are at a point time in the PC hardware market where the power demand is rising consistently and from what we are hearing, things aren't going to stop. Enthusiasts PC builders and high-end gamers are constantly aiming for the highest-end products with CPUs sipping in an average power of around 200 Watts and GPUs now ending up around the 300-400W range. This along with all the combined hardware in one high-end rig is going to set you close to 800-1000W power requirement. Intel requires the PSUs to have a slew rate of at least 5 A/μS, so an electronic load must be at least as fast as that figure to be able to perform ATX 3.0 compliance testing. From a professional’s point of view, proper testing would require the testing equipment to be at least 30% faster than the absolute minimum required. This requires a highly advanced (and expensive)electronic load with multiple modules, like the Chroma Mainframe andHigh-Speed modulesIntel themselves is using, which has a total slew rate of 8 A/μS and it would need only 0.02 ms to get the load from 65 A all the way up to 215 A – and that still is 20% of the test’s required 0.1 mstime in our example, a figure that many expertswould find far too great for precise measurements.

Our First Foray Into ATX 3.0 PSU Testing: A High Hurdle to Clear

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.

Both of our approaches ultimately failed, as all of the PSUs we currently have available would shut down at most tests above 120% power excursion- therefore we need not worry about our loads being insufficient to test the MEG Ai1300P at 200% excursion (we are also currentlylimited to 2400 Watts on the 12V line). Theoretically, testing with the RMS-equivalent duty cycle times should work and the PSUs should not be shutting down, yet we cannot claim that the units are not technically capable of meeting their specifications when our equipment is not meant to be running such tests.Intelligent Fan Mode: Automatically detect the power loading and internal temperature to adjust the fan speed. When the load is below 55% or the temperatures are below 70 degrees, the fan will automatically stop to reduce noise With native 16 PIN PCIe connector this power supply is ready for Nvidia® GeForce RTX® 40 Series graphics cards. It can freely pipe up to 600W of power to PCIe 5.0 graphics cards. Details about the extent of our regulation by the Financial Conduct Authority are available from us on request. The MEG power supply measures 86mm x 150mm x 160mm which is somewhat smaller in length than the larger 200mm units we have seen in recent months.

Load regulation holds well across the board. Within 2%. This is a very good result for MSI. MSI MEG Ai1300PIf you believe everything that the brand's marketing material states, then AIO coolers MSI released were the best coolers in the world, not the market, the world. 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.
