How to choose a power supply for a PCBasics of choosing a reliable and balanced power supply for your home, office and gaming computer
The power supply is top for the money, considering that I got it even cheaper
23 November 2020

-Price -Quality of workmanship -Semi-modularity -24pin and 8pin CPU cables with black sleeving -Flat cables for the graphics card and peripherals -Quiet -Excellent circuitry, almost at the level of seasonic))
-Smell in the first day or two of use
-Had difficulties connecting the 24 and 8 pin to the motherboard, as these cables are a bit stiff
-Strange connection of SATA devices, as the branching goes directly from the bundle, and it's impossible to connect to the quick-release SSDs on the case, only the very last SATA, which is straight
