MSI MEG Ai1300P PCIE5

Product Information

I eventually stopped the software at around 68-69 C because I wasn't interested in seeing how hot it would get before it shut itself off.

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. MSI Support has told me so much conflicting information that I'm simply not sure what is true. One support member told me the PSU would turn itself off at 70 C, another told me that's at 105 C. One support member told me the fan would start once the PSU reaches 70 C, another told me that it won't start until power output is greater than 1000W. All the while, every time this information is being communicated to me, I kindly ask them to confirm [due to so much conflicting information], I'm put on hold, then I'm told it's confirmed. When I raise previous conflicting communications, I'm told the last support member must have been mistaken. In terms of electrical performance, the MSI MEG Ai1300P PCIE5 does deliver. Keeping its massive power output in mind, the MEG Ai1300P manages outstanding power quality, with excellent voltage regulation and remarkable filtering. MSI’s engineers did not neglect the minor voltage lines either, which often are not as well filtered as the main 12V line. The efficiency of the MEG Ai1300P barely meets the 80Plus Platinum certification standards but it is extremely stable and practically unaffected by high ambient temperatures. It also is very efficient at very low loads, which is important for a unit with a very high-power output.

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. Today to test the power supply we have taken it into our acoustics room environment and have set our Digital Sound Level Noise Decibel Meter Style 2 one meter away from the unit. We have no other fans running so we can effectively measure just the noise from the unit itself.

The cables are a mixture of sleeved and custom sleeved to fit into a variety of builds. MSI also supply a MINI USB to USB cable as this power supply can be controlled via MSI software. 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 have worked with CWT in the design of this power supply and they allow the end user to switch between single and multi rail modes to cover a variety of possible system configurations. MSI support this unit with a 10 year ‘limited' warranty – depending on the region.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.

The rear of the box highlights some of the key features along with some technical details including the cable configuration. We take the issue of noise very seriously at KitGuru and this is why we have built a special home brew system as a reference point when we test noise levels of various components. Why do this? Well this means we can eliminate secondary noise pollution in the test room and concentrate on components we are testing. It also brings us slightly closer to industry standards, such as DIN 45635. With the determination of transcending current gaming products, the flagship models push the limits of what an extreme gaming series can be. My biggest issue is the Weekly consumption, as you can see it Skips some days and doesn't bother recording the data to the graph at all, even though my PC is on 24/7.

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. The OEM behind the creation of the MSI MEG Ai1300P is Channel-Well Technologies, or CWT. They are a very popular and reputable manufacturer of mid-to-high-performance PC PSUs. This platform can be described as a hybrid, as it essentially is a standard analog platform but with extra digital electronics added to it. The digital electronics allow for the monitoring of the unit’s basic performance figures, as well as limited control (fan cooling profile, OCP limits, etc) via the USB interface. What really does stand out is the heatsinks, which do have plenty of dissipation surface but are also designed to be aesthetically appealing – an odd (but not unwelcome) design choice considering they should not be visible to the end user. This ‘Silent Gale' fan (PLA12025S12H-4) seems to have been around for 6 years under other MSI brand names such as ‘TORX'. 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. Electrolytic: 5x Nippon Chemi-Con (105°C, W), 1x Nichicon (2-5,000h @ 105°C, HD), 4x Nippon Chemi-Con (4-10,000h @ 105°C, KY), 1x Nippon Chemi-Con (2-5,000h @ 105°C, KZE), 3x Rubycon (4-10,000h @ 105°C, YXJ), 3x Rubycon (4-10,000h @ 105°C, YXF)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 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: To be fully compliant with ATX 3.0, there’s also a timing value that the power supply unit must meet. The MEG Ai1300P PCIE5 is fully compliant with that timing value as shown in the chart below. MSI MEG Ai1300P & MPG A1000G Gen5 PSUs Final Impressions One interesting feature MSI have incorporated- the two panels on the side are held in place magnetically, so they can be easily removed and flipped – depending on your chassis install rotation. This way you get to see the ‘MEG' logo as you want (or you could in theory remove them completely to get rid of some of the gold accenting if you wanted). These do have a tendency to drop off quite easily so you need to be careful when handling the power supply. 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.

One strong suit of this PSU is that like all high-end 1000W+ designs, it comes with six independent PCIe power connections. Why is this important? Well, future graphics cards are going to resort to the new Gen 5 connectors and you'd either need to get a proper Gen 5 PSU or a PSU that has at least 3 connectors to meet the demand for next-gen high-end cards. You can either use them or simply plug in the 12VHPWR connector for the NVIDIA RTX 40 series graphics cards which saves you the hassle of cable managing all those extra connectors. 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 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.
