The ROG Loki 850W Platinum is a small power supply, but it is one of the best-looking SFXs on the market, and in terms of quality, it also ranks very well in the market. The product has many positive features including the flexibility of the cables made of fabric material, which allows it to be placed in a small case without any problem. This is a top-of-the-line product whose price is certainly reasonable

I was not fully satisfied with my PC workstation and decided to make an investment and build my own build. Such a machine is definitely a step forward in terms of performance for handling video editing and streaming. I used an Asus rog strix b760 g gaming WiFi D4 motherboard, Asus TUF Gaming rtx 4070 ti gpu, Asus rog loki 850w power supply, Asus rog ryou 3 heatsink and Asus prime case ap201.

ASUS Prime AP201 is one of the best choices for those who are looking for a small tower case and do not want too extreme solutions. It gives you the convenience of being able to use micro-ATX motherboards, ATX power supplies, and radiators up to 360 mm, as well as large GPUs, without worrying too much about having to miniaturize all your hardware. Performance is good, thanks mostly to the well-optimized airflow, but watch your ears because the internal fans get loud.

TuttoTech

The power supply is one of the most important components in building a pc, and the ROG Thor is of unparalleled quality. Aesthetically, it is beautiful, and the inspiration from Norse mythology is clear. powerful yet compact, the ROG Thor is sure to please everyone
