MSI MEG Ai1300P PCIE5 Power Supply Unit, UK Plug - 1300W, 80 Plus Platinum, Fully Modular ATX 3.0, PCIe 5.0 GPU Support, Japanese Capacitors, Gaming Intelligence, Sleeved Cables - 10 Year Warranty

Using the MSI MEG Ai1300P PCIe5 with my Ryzen 9 9800X3D and RTX 5080 Founders Edition — and it's been flawless so far. My build has 11 fans, and this PSU handles everything effortlessly. No coil whine, no hiccups, and the power delivery is stable even under heavy loads. The fully modular braided cables are a nice touch — high quality, flexible, and easy to manage during installation. The PCIe 5.0 support makes it future-proof for upcoming GPUs as well. Highly recommended if you're building a top-tier rig and want peace of mind with clean, reliable power.

It is supporting the latest 9950X3D with RTX 4090 without any hiccups. Amazing support for all the power requirements of my MSI ACE Motherboard and Graphics Card.

Stable for 9800x3d and 7900xtx build Msi monitoring app works well too

one of the best power supply on the high end. now the hardware is pretty solid, build quality is good, cable's sleeved, and plenty of pcie cables which i required when i was in search of a psu. but the software is a little sluggish and slow, it does allow you to monitor your wattage usage through it and can configure your power rails, fan speed how you want.

I was collecting parts for my pc and i ordered it 6 months ago. Yesterday when i finally try to build, the power supply wasn't working. I know it's my fault, i didn't check it early if it's working. I couldn't return it obviously, it comes with 10 years warranty, someone help me, i have idea what to do next...

Enda anledningen till att jag handlade detta aggregatet var att det mindre i samma märke var slut. Resonerade som så att det är inte fel att ha extra kraft och att köra det på lägre nivå än max antagligen gör det mer effektivt.

Just got it cos it fit the build. Build quality is good, stable power.

Après plusieurs semaines d’utilisation, le MSI MEG Ai1300P PCIE5 s’est révélé irréprochable. La puissance est largement suffisante pour une configuration haut de gamme, et la stabilité est exemplaire, même lors de longues sessions de jeu. Les câbles entièrement modulaires facilitent énormément l’installation et le rangement. Les composants sont de qualité, notamment les condensateurs japonais, et le bloc reste très silencieux. La compatibilité ATX 3.0 et PCIe 5.0 en fait un choix idéal pour les cartes graphiques récentes. Avec en plus une garantie de 10 ans, c’est un achat sûr et durable. Rien à redire : un excellent bloc d’alimentation pour qui cherche la fiabilité et la performance.

I have been a tech 20+ Years and always used the same 2 brands before, So I was a bit nervous trying a new brand of PSU. I loved MSI from working with them in business for 11 years so I figured I'll give it a go! My MSI Products in my System: ( My Case is a Lian Li Evo XL. PSU is Mounted with the fan facing out for ventilation ) MSI MEG Ai1300P PSU MSI MEG Z790 ACE MAX MSI MLG RTX 4070 SUPER Video Card MSI MPG CoreLiquid K360 V2 on a i7-14700K FIRST: MAKE SURE YOU GET THE Serial # and "CHK" Code off of the PSU itself before you install. You need both those codes to register it with MSI and also the full recognition and integration into the MSI Center Software. Which is a BIG shiny plus in my book to monitor and manage the PSU. * THIS PSU DOES NOT HAVE PROPRIETARY CONNECTIONS TO THE PSU Yay!! BEWARE OF THOSE THAT DO! I purchased a BeQuiet! because I love their products too, just to find out all the cables were proprietary on the PSU connection end and sent it back. This PSU was about $140 more than the BeQuite 1200W I originally bought. 1. Installation: PSU is a GREAT size. I actually ordered this to replace another because the other had really stiff cables and was eating a lot of room. 2. Cables: Very soft and flexible. Super nice tight fit, you KNOW if it's in correctly. The ONLY negative is the clip braids. You do put them on yourself. Some go on like butter clipping the cables in. I gave up after I ran into 4 hard clips in a row, my hands were raw lol. I just fitted the cables how I wanted them and left the clips I put on in place. * If you are planning on using the New connector to your Video card, make sure there is space in your case. To get it to fit with no tension you need about 2-3 inches of clearance to bend the cable just right. I don't use adapters. This comes with several adapters as well from normal PCI-E to the New one. 3. Software Interaction: Plug the USB interface cable in last that connects to the motherboard. Makes things easier. The only thing I'm unsure of is why the software is registering it as a MEG Ai1000P instead of the Ai1300P. I will post a screenshot of how easy the software is and what it shows you. The screenshot is from IDLE. While doing a FULL LOAD test the PSU efficiency was at 90-93%, perfect. The Real-time dashboard is great as well. 4. This PSU performs great, runs cool. My only tip on the software: The PSU fan will be in 0RPM mode even up to some super high temps, really doesn't matter tooooooo much. BUT I just set it to a neutral 1200RPM and the PSU went down 30C, Crazy. In my Case where it is mounted right behind my proc and motherboard, that made a good difference on my CPU/Mobo temps as well as I observed in just idle/basic and gaming. This I really think is a great thing for consumers who want to futureproof themselves in this weird market we have right now. *Final Thought* Is the PSU Overkill? Depends on your outlook. Buy what you want. If you're torn on the Ai1000P or the Ai1300P (this). There are differences, just look into the manual on MSI's site. I do NOT regret purchasing this at all. Expensive, yes it is. Worth it, yes it is!
