MSI MEG Ai1300P PCIE5

Product Information

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. This ‘Silent Gale' fan (PLA12025S12H-4) seems to have been around for 6 years under other MSI brand names such as ‘TORX'. Multi/Single Rail Switch: It can switch between single and multi-rail according to the needs of users while taking into account high current output and safety protection. The biggest change since the addition of the 12V 6-pin “PCIe” power connector in the late 00s, the ATX 3.0 era has come with some new opportunities, both for computing products and for computing problems. The use of adapters has, in short, not gone well for front-runner NVIDIA, with a small but serious number of incidents of 12VHPWR adapters melting down. Meanwhile on the power supply side of matters, this has been a not-unwelcome boon; not only are native ATX 3.0 power supplies the preferred way to go from a design standpoint, but the adapter problems have helped to underscore this advantage. So for the power supply vendors who are among the first to get their ATX 3.0 designs out the door, there’s no shortage of demand for their latest and greatest wares, as well as a fresh opportunity to innovate and set themselves apart from the competition.

Anyway, I just set a custom fan speed at 710rpm and as you can see it sits in the low 20s, Even when gaming with Zero Dawn max-out settings it never gets above 35c now. 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. 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. Aiming for unwavering product quality and performance stability, the power supply comes with 100% Japanese 105° C capacitors and solid capacitors. Inside the outer box is a bag of cables and accessories and the power supply itself, wrapped in a plastic bag, sandwiched between two pieces of foam.

The fan is hidden behind a shroud with another gold accented panel. We will take a closer look at this fan when we open the power supply shortly. 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.

The mysterious triangle is a symbolic icon of MEG's infinite power, with the triangle's slope further extending the three pillars of MEG's core characteristics: legendary, loyalty, and luxurious. Kitguru says: The MSI MEG Ai1300P is a high performing power supply with interesting software enhancements that will appease the high end enthusiast audience. This modern design adopts quality internal components with 105c rated Japanese capacitors to help justify the eye watering asking price. Load regulation holds well across the board. Within 2%. This is a very good result for MSI. MSI MEG Ai1300P 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. MSI are trying to attract the user base who love to tinker with their hardware via dedicated software. I appreciate the concept of being able to control a power supply via a program however MSI Center is a clunky, unpleasant tool to use at the best of times. While using MSI Center my only thoughts were to get it deinstalled as soon as possible. I would personally just run the power supply in a default single rail mode mode all the time and let the fans operate automatically without the need for a software install. The other capabilities of MSI Center such as real time monitoring will be interesting to a very niche audience, but perhaps for only a short while.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. 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.
