Good Solid Power Supply
Iâve been using the MSI MPG A1000G PCIE5 for a few weeks now, and so far, itâs been a solid performer. It supports PCIe 5.0 and ATX 3.0 standards, which is useful if you’re planning to run newer GPUs that require the 12VHPWR connector. Having that built-in is definitely convenient.
The build quality is good, and the modular design makes cable management easier. The included cables are decent quality and long enough for most mid- to full-tower builds. It’s also quiet â the fan rarely spins up to noticeable levels, even during gaming or heavier workloads.
Efficiency is in line with its 80 PLUS Gold rating, and I havenât experienced any stability issues so far. Itâs not the cheapest option out there, but for those wanting a bit of future-proofing, itâs a good solid option, I bought another one for my second rig.
Overall, it’s a dependable power supply that does what it claims without fuss. Not flashy, but gets the job done.

Lovely premium PSU, not worth the current £130 price but for anything around £100 it’s great.
I was very relieved when i received this item. I had had to return a motherboard AND ram as i was building this computer so for a start, the fact that this works as intended is brilliant. It has a low-noise option which i make use of and a very good power efficiency, slightly above the 80plus rating, not that that matters a lot.
The box is lovely, glossy printing and thick cardboard, which is a great bonus and helps it feel like a premium product. It has 2 cpu power cables and 3 PCIE ones which is more than a few others around this price point. The 12vHPWR, though not in use by me, has a yellow connector at both ends to make sure you plug it in fully and don’t explode your lovely NVIDIA gpu. I will add that pcie 3.1 standard apparently doesn’t have such issues, but as a 3.0 product it’s a good way to alleviate it.
Will rate 5 stars, no issues whatsoever unlike other products from ASUS AND CORSAIR AHEM…
Anyway 5/5 does what it says on the tin and with great style, efficiency and price if you get it for £100-110

Perfect Power Supply
This power supply is great. The build quality feels solid and premium, and everything about it looks and works like it should. The cables are really easy to manage, which helped me keep my build clean and organized without too much effort.
The best part is the PCIe 5.0 support, which works perfectly with my RTX 5070 Ti. No need for extra adapters, the included cable fits right in and powers the GPU without any issues.
Overall, I’m really happy with it and would definitely recommend it.

The MSI MPG A850G PCIE5 power supply is an impressive choice for those building high-performance gaming PCs or workstations, especially when paired with a powerful CPU like the AMD Ryzen 7800X3D and a GPU such as the RTX 4070 Super. Hereâs a breakdown of the key aspects:
Positives:
* Tiered Performance: The MPG A850G PCIE5 is in the higher echelons of power supplies, offering excellent build quality and stability. With an 80+ Gold certification, it delivers efficient power conversion, ensuring that your components receive clean and reliable power without wasteful heat generation.
* Quiet Operation: One of the standout features is how quiet this PSU runs. Even under heavy load, it manages to keep noise levels impressively low thanks to its high-quality fan and efficient cooling design. If youâre looking for a power supply that wonât disrupt your gaming or work environment with loud fan noise, this one delivers.

This PSU handles the power demands of these components with ease, ensuring that your system remains stable even during intense gaming or content creation sessions.
Negative:
Stiff Cables: While the build quality is solid, the cables are somewhat stiff, which can make cable management a bit more challenging. They donât have the flexibility of some other high-end power supplies, which can make routing them through tight spaces or behind the motherboard tray a bit cumbersome. Itâs a minor inconvenience but something to keep in mind if youâre aiming for a clean and tidy build.
Conclusion:
The MSI MPG A850G PCIE5 is an excellent power supply for those building a performance-driven PC. Its quiet operation, efficient power delivery, and sufficient wattage for high-end components like the Ryzen 7800X3D and RTX 4070 Super make it a solid choice.

Ho recentemente acquistato l’alimentatore MSI MAG A750GL per il mio sistema e devo dire che la mia esperienza con questo prodotto è stata assolutamente positiva.
Le caratteristiche di questo alimentatore sono molteplici. Innanzitutto, la sua potenza di 750W è più che sufficiente per alimentare il mio sistema gaming ad alte prestazioni. Ho apprezzato la sua efficienza energetica, che mi ha permesso di risparmiare sull’energia elettrica senza compromettere la stabilità del sistema.
L’alimentatore MSI MAG A750GL offre anche un’ottima gestione dei cavi. I cavi sono di lunghezza adeguata e ben organizzati, il che ha semplificato notevolmente il processo di cablaggio all’interno del mio case. Questo ha contribuito a migliorare l’aspetto generale del mio sistema, evitando l’ingorgo di cavi e consentendo un migliore flusso d’aria.
Un altro punto a favore di questo alimentatore è la sua silenziosità . Le ventole sono state progettate per funzionare in modo silenzioso, inoltre non ho mai avuto problemi di surriscaldamento o di rumore fastidioso proveniente dall’alimentatore.
In conclusione, l’alimentatore MSI MAG A750GL è un componente eccellente per qualsiasi sistema desktop. La sua potenza, l’efficienza energetica, la gestione dei cavi e la silenziosità lo rendono una scelta ideale per gli appassionati di PC. L’assistenza clienti di MSI è un valore aggiunto che ha reso l’esperienza complessiva estremamente positiva. Consiglio vivamente questo alimentatore a chiunque stia cercando un’opzione affidabile e performante per il proprio sistema.
