    • Works great so far. Good Bargain, from a reputable company.
Size: 850W
I picked this up during prime days. Was 110, is modular, includes 12vhp without issue. Is running a ASUS Strix Z790-e Intel 13th gen i7 W/ ASUS TUF 4070Ti Super OC and has 11 fans including those on the AIO. The cables are a little stiff but it wasn't an issue. Case Antec 1FT, it has plenty of cable management features. CONNECTIVITY HAS BEEN NO ISSUE. So unless it dies at warranty time its been a solid psu( has low noise function, but as you can tell with the fan count, I prefer it run cool). As for ease of installation that'll depend on the case. The outside bracket to the PSU on the Antec slides in and out of the power housing. ... show more

    • Powering My Rig with Confidence: The MSI MPG A850G PCIE5 PSU Delivers!
Size: 850W
I recently upgraded my system with a new graphics card, and that meant it was time for a power supply that could truly keep up. The MSI MPG A850G PCIE5 PSU was the perfect choice, and I'm incredibly impressed with its performance and features. Installation was a breeze thanks to its fully modular design. Only connecting the cables I needed made for a much cleaner build and improved airflow in my case. The included native 12VHPWR connector for PCIe 5.0 graphics cards is a game-changer, eliminating the need for bulky adapters and ensuring stable, reliable power delivery to my hungry GPU. Beyond the easy installation, this PSU runs incredibly quiet. Even under load, the fan is barely audible, which is fantastic for maintaining a peaceful computing environment. I also appreciate the peace of mind that comes with MSI's reputation for quality components. This PSU feels robust and well-built, and I'm confident it will provide stable power for years to come. If you're building a new high-performance PC or upgrading an existing one, especially with a modern PCIe 5.0 graphics card, the MSI MPG A850G PCIE5 PSU is an absolute must-have. It delivers excellent power, is easy to work with, and runs quietly. Highly recommended! ... show more

    • Good powersupply, just caution when buying pre-owned
Size: 850W
Bought from amazon resale (basically bought pre-owned), got the powersupply but was missing the ATX 24Pin. called and recieved a partial refund of $20, which luckily is exactly how much it costs to get a replacement cable over the phone from MSI. Just be warned that if you buy used from the amazon resale option you may face missing items even if they dont disclaim that and it adds about a week of downtime to your new build. Apart from that amazing powersupply, and amazing upgrade to go along with my 5070. ... show more

    • Loud by default, can be silenced. Native 12v2x6.
Size: 850W
As a PSU, it seems to work just fine - successfully powering a 4080 Super through just its native 12v2x6 port. The cable for said port is really easy to plug in and to make sure it's plugged in as well, thanks to the bright yellow plugs. Do make sure to plug it in fully, otherwise some very very bad things could happen. 🙂 The fan inside is quite loud, but there's a little button on the PSU that lets you silent it. Obviously, this means that the fan won't run, but I think it's a fine tradeoff for when you're not doing anything too intensive. ... show more

These power supplies are top notch and a great upgrade over my old semi modular set up. The single gpu graphics connection 12v2x6 makes things easy and for a clean set up, if you decide to use it. 850 watts is perfect for my 7800xt gpu and ryzen 7 7700x . The modular flat cables def help with keeping things clutter free. Power supply stays cool and silent with a 0 rpm mode which can be turned off. The overall size of the unit itself is very compact and light weight compared to some others units. There no rub or lights on this unit , but does have a very sleek silver MPG design on the side. Looks cool in the case. Great purchase. ... show more

    • Excellent, except for one kinda big issue.
Size: 850W
This is a great PSU. Has all the features you'd want, top class. I just wanted to take the time to mention my big dislike, and that's the complete absence of any instructions whatsoever. They are just not present. I couldn't even find the info I wanted on the MSI website. I literally had to post on Reddit to find an answer, and since 100s of people have commented on the post. So I'm obviously not alone. At the time of purchase, two of the cables that came with this PSU were new to the world, in terms of how the GPU is powered, yet MSI provided no instruction at all. And that has got to change. Because connecting things wrong can total your entire PC, and can also create public safety issues, like fires. I'm a very experience PC builder, so I was not too worried for myself, but I do fear for others. Therefore, just do your research first!!! ... show more

    • Excellent product quality, quiet and powerful
Size: 850W
Needed a new PSU for my server and this perfectly fit the bill. My server idles at a low enough power that the fan barely ever turns on, so all I can hear is the drives in the computer. The included cable bag in the box is fantastic so I can leave cables in there and not mix up compatible ones. Overall, very good value at the price I bought it at, 95 dollars. ... show more

Works great. Was easy to install with no issues with connections. They supplied more cables than my setup needed. I've had no issues with it since I've built my computer in September. Fit perfectly inside the Lian Li Lancool 216 Mid-tower.
