MEG Ai1300P PCIE 5 & ATX 3.0 Gaming Power Supply – Full Modular – 80 Plus Platinum Certified 1300W – 100% Japanese 105°C Capacitors – Compact Size – ATX PSU

Absolutely worth the money.
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.

A great psu for the money.
Has dedicated 8pin 6 of them each cable is nicely sleeved and high quality with easy cable management. Worth the money and has two cpu slots as well where you can plug them all in. This is overall a really good buy for 289.99

Powerful, quiet and efficient
This is a high quality product from MSI. The main drawback reviews and other owners seem to mention is the fan noise, but from my experience this isn’t an issue under real world operating conditions. My system with a Ryzen 7600X and a 4090 draws ~670 watts while running GPU + CPU torture tests and the fan did not turn on until the unit reached almost 70C, and at that under 900RPM which wasn’t really audible over my other components running at full tilt. This is an extremely unrealistic operating condition as well, while gaming you’ll rarely exceed 500 watts and the fan will literally never turn on. In short, it’s a none issue.My biggest problem with the unit was the cables, especially 12VHPWR connector, which doesn’t really seem to “click” into my 4090. It’s fully seated all the way, but its only held in by tension and could be pulled out just by the cable bending. It’s also not individually wrapped like the other cables which seems like an oversight.The monitoring software is actually decent, and at least if its your only MSI product, doesn’t seem very intrusive. It shows you your PSU stats and lets you control the fan and rails, not much else. Would recommend installing for owners of this PSU as it is nice to know the total power usage of my PC.

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.

Absolutely perfect. What’s even more complete about the configuration is that there are four detachable magnet ornaments for the power supply that you can place anywhere inside or outside your PC case!
