GREAT BUDGET POWER SUPPLY!
Style: MPG A850GS PCIE5
MSI MPG A850GS PCIE5, Fully Modular Gaming 850W Power Supply, 80+ Gold is an absolute beast of a power supply. Packaging was excellent, and everything arrived in perfect condition. Installation was straightforward thanks to the fully modular design, which made cable management much cleaner than previous power supplies I've used. The build quality feels premium, and the included dual 12V-2x6 cables are a nice bonus for high-end GPUs. Knowing it's ATX 3.1 and PCIe 5.1 ready gives me confidence that this PSU will handle future upgrades without any issues. The unit runs extremely quiet, and the 80+ Titanium efficiency is a great feature for reducing wasted power and heat. MSI also backs this power supply with a 12-year warranty, which speaks volumes about their confidence in the product's reliability. If you're building a high-performance gaming or workstation PC and want a top-tier PSU that should last for many years, this is an excellent choice. Highly recommended.

Powerful and silent, a real good choice! Powerful and silent, a real good choice!
Style: MPG A850GS PCIE5
The MPG A850GS provides enough power for the 9800X30 and RX9070 XT build that I have, with some room to grow. Overall I really like the size of the power supply it's been a while since I have purchased a PC power supply and was kind of surprised by how compact the unit is. It's fully modular and provides more than enough cables for nearly any build. The unit is quiet even with the fan on, it also offers a silent operation mode if you need that. So far I do not detect any type of coil whine or anything that would impede it's operation. I am extremely happy with how this unit performs and functions. It was super easy to install and it feels quality built. The durability should last for years. The warranty is top notch too!

Quiet performer!
Style: MPG A850GS PCIE5
Found it for a good price and made an upgrade from my previous Segotep unit, which went bad on the CPU power port. This one is future ready, comes with a fan turn off switch and twin 5.0 pcie ports . There's also an extra cable for the new 600w pcie to older gpu pcie pins to use with pre 4070 gpus. Lots of ports for the accessory connectors. Very quiet and great build quality.

Working well
Style: MPG A850GS PCIE5
Bought to replace an aging Corsair, and happy with the upgrade. Like the bright 16pin for when this PC moves to a newer GPU that uses it. Quality cords, like the compact size, now to see how long it lasts.

Decent PSU, gets the jobs done, but there is a slight coil whine
Style: MPG A850GS PCIE5
I bought this PSU to replace an older FSP second handed PSU that started showing signs of deterioration of voltage regulation. This PSU's voltage regulation is much better than that on the FSP, and the voltage hardly sags with light to moderate load. The PSU's fan is very quiet, and it is literally inaudible even with the 0 RPM fan mode turned off. However, one thing that I noticed is the coil whine. There are 3 clips in the video. The 1st one is click sound the moment when the PC turns on. The click happens before the relay clicks, which has a few seconds delay. I assume this is caused by inrush current charging the big capacitor. I didn't notice this sound on my old FSP PSU. The 2nd clip is coil whine when I turn on the PSU with nothing attached. This whine is quite loud and can be heard distances away. The 3rd clip is a slight ticking noise when PC is idle. This noise isn't loud and can only be heard if I put my ear right next to the PSU. Not sure if any of these noises are normal, but the PSU has been working with no issues since I installed it.

Perfect purchase! Perfect purchase!
Style: MPG A850GS PCIE5
Really amazing quality power supply. The best thing about it is the cables. They made routing and management such an easy task. I would most definitely recommend if you (like me) have to keep your cables neat and clean but also enjoy simple assembly and install. For sure a 10 out of 10

Loud electrical squilling noise
Style: MPG A850GS PCIE5
There's electrical squilling or buzzing sound soon as it was powered on. And the fan is almost rubbing the front fan grill i don't know if it was because It was just in the manufacture box no protection. It sounds unsafe to even plug it into my computer i've never had one that sounded like this. I had to go back to the cooler master bronze that i've had over 5 years and it is silent No noise i thought was upgrading to better quality gold MSI psu but they needs better quality control this should have never left the manufacture.
