Hello, help with advice.
I decided that I need to buy a UPS for a working PC, the configuration of which is:
CHIEFTEC 500W ATX 2.3 APFC,
Gigabyte B450M DS3H,
Ryzen 5 2600,
GeForce GTX 1650 D6 Windforce OC 4GB GDDR6,
GOODRAM IRIDIUM DDR4 8GB 2400MHz,
SSD APACER AS350 480GB SATAIII.
A UPS is needed to stabilize the voltage and protect against blackouts. The battery for a few minutes will be enough to normally turn off. PC. Which PSU to choose for normal operation with a UPS so that there are no problems in their joint work?
UPS up to 6k rubles
PSU up to 3.5k rubles
