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

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...

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.

bought MSI MEG 1300w for my new 5090 msi build. feels like a serious piece of hardware right out of the box. It’s solid, n heavy, and clearly well made, with premium capacitors and clean modular connectors. The sleeved cables look great and make cable routing simple and tidy. the little clips are very useful as well. In use, it’s dead silent most of the time—the fan rarely turns on, and evven when it does, it’s barely noticeable. Power delivery is rock steady, and everything about it feels engineered for long term reliability. the ATX 3.1 and PCIe 5.1 support means it’s ready for any modern MSI setup without other cables. It’s not the cheapest PSU, but you can tell where the money goes: build quality, stability, and silence. The 10-year warranty is great too. use for 1 more build for sure.

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.

Unlike many PSUs in the 1000+ watt range, this one maintains the small form factor of lower-powered PSUs, and it does so without getting overheated. Granted, I'm running an i7-13700k with my trust old GTX 1080ti, but still. One of the other major selling points of this PSU is that it has a dedicated 12V rail for your GPU. I have no issue running my old 1080ti on it and now I'm future-proofed for an eventual upgrade to an RTX 4090. Full modularity is always great, of course, and this PSU comes with plenty of cables for every type of connection you might need (except IDE, but you're spending way too much on a PSU if you're using this for a retro PC, lol). Also, I know some reviews of this PSU say that can get a little noisy under heavy loads, but I've yet to experience that. However, that could also be because I'm already running a huge air-cooling setup and can't hear the PSU's fan. Having a whisper-quiet PC has never been a concern for me, anyway. I will say, it would be nice if MSI had used a 140mm fan rather than a 120mm, as the chassis of this PSU certainly could accommodate it. A minor design criticism, ultimately. My only other criticism is that with a bottom-mounted, fan-down installation, there's a big information sticker that's highly visible on the face-up side. This doesn't affect anything, it just looks ugly. I don't know where else you'd put such a sticker, though, given that there's minimal real estate for one, but you'd think that as a gaming-oriented PC hardware manufacturer, MSI would've considered that many gamers care almost as much about aesthetics in their builds as they do performance. As far as PSU's go, it's a nice-looking box, other than that damn sticker. I certainly wouldn't pass on this PSU for that, though. This thing is a beast and a great choice, despite being on the pricey end, that will future-proof your system. Also, that sticker could relatively easily be removed if you so chose to do so. Overall, 5/5, highly recommended.

Si buscas una nueva fuente de poder para una RTX 4090 / 4080, está es una de las mejores opciones en el mercado actualmente gracias a su certificación ATX 3.0. La adición principal de esta clase de fuentes es un puerto "12VHPWR" que permite usar un solo cable para la tarjeta de video. El cable 12VHPWR de esta fuente puede enviar hasta 600W a la tarjeta de video (otras fuentes ATX 3.0 de capacidades menores a 1200W suelen cargar cables de 450W o menos). Aunque la RTX 4090 solo necesita un cable de 450W, esta fuente es una buena opción en caso que decidas conservarla para varios upgrades. También con el cable que incluye te evitas usar el horrendo adaptador que viene con la RTX 4090 / 4080. La mayoría de los cables de las fuentes son bastante flexibles (incluyendo el cable de 24 pines!). El cable 12VHPWR es algo rígido en comparación al resto. Si tu gabinete no es muy ancho, tendrás problemas en colocar la tapa del lateral. Esta fuente también es semi-digital; al conectar el usb que se encuentra en la PSU a tu PC, puedes usar el software de MSI Center para poder monitorear el uso de cada riel. También permite ajustar la curva del ventilador y cambiar entre un modo multi-riel y mono-riel para el canal de 12V. Aún y aunque estuviese usando al máximo una RTX 4090 con un Ryzen 9 7900X, el ventilador de la PSU corre a una velocidad tan baja que no me fue posible identificar el ruido del ventilador de la PSU sobre los otros ventiladores de mi PC. En conclusión, una buena fuente de poder ATX 3.0 para usarla para varias actualizaciones aún y aunque el precio es bastante elevado.
