great product for a great brand
i have always liked gigabyte, now i am building aka rebuilding my PC. leaning more towards the gigabyte brand . This Power supply is the second in the gigabyte name, my first is the Gigabyte B550 Master motherboard. Gigabyte is known for their great products and the warranty, upon registering this product on their website it extends the warranty from 1 year to 5 years. it is a great way to COVER, COVER you purchase. NO i am not getting paid nor am i sponsored with gigabyte to say that . i do wish i was sponsored, i would promote them on my twitch channel. Power standard 850 watt for to days computer needs , enough power noise level to me seems to be 0 speed no speed on a power supply very easy to install - 4 screws and plugs for days, enough to run everything you need and it meets the needs of the newer GPUS Weight - 3.3lbs to 5.5 lbs

Great Power Supply
Bought this for a new computer I was building and it has been great. Plenty of extra power for anything that I add to the system. I like the modular design of the cabling and it was easy to hook up. Very quiet and the cables are of good quality.

Más de cinco semanas para la entrega
Buena calidad, hasta el momento funciona correctamente, tiene un detalle y es que los cables no vienen marcados lo que hace difícil identificar para que tipo de componente son. Otro detalle es que la entrega fue demasiado lenta a Colombia, se demoro más de cinco semanas, fue enviado por Pasarex

Bought new but was sent used and defective product
I ordered this new but the product that arrived was clearly both used (e.g. inner packaging was already ripped up) and defective (probably why it was returned the first time. I decided to return it so hopefully they do not turn around and try to sell it again as new (or even as used). Photo shown is loose piece of solder in the case. I didn’t try running it, but I don’t imagine it could be good to have a loose, conductive piece of metal flying around in there when the fans start running.

Works perfectly
The orginal box was not in the best of shape, but that did not matter because the PSU and cables were immaculate. I used this power supply for an older z270 board with all necessary components that was lying around. Everything powered up and computer was running perfectly. Definitely would buy from seller again especially a used item in such great shape as this PSU was.

Runs Cool not Hot
Very stable power supply that produces less heat than I expected

Solid Performance
I needed a reliable PSU for my build, and the Gigabyte GP-UD850GM has been solid so far. It provides plenty of power for my RTX 4070 Ti and Ryzen 9 setup, and I haven’t experienced any stability issues. The fully modular design makes cable management a breeze, and the overall build quality feels premium. It runs quietly, which is a big plus. My only gripe is that the cables are a bit stiff, making routing them a little tricky. Overall, if you need an 850W power supply with stable performance, this is a great choice. Just be prepared to spend some time managing the cables!
