Quiet, sufficiently cool power supply. Silent operation; the unit stays cool thanks to the 11 cm fan; Taiwanese Teapo capacitors, components from FSP; The 500-watt model delivers 480 watts on the 12V line, which pleases me The power supply almost meets the 80+ Gold certification.  Radislav Anufriev: use be quiet! BN297 few months |
I do not recommend buying it; due to the noisy fan, it's impossible to work properly. For this price, there shouldn't be such issues. no The fan makes a noise like a train. The problem appeared after half a year.  Artem Goyko: use be quiet! BN299 more than year |
Squeaking and humming of fan bearings. Nothing NOISE. WITHOUT HEADPHONES, WHEN CASE FANS AT 400 RPM, THE UNIT STARTS TO MAKE A TERRIBLE SOUND ReuzzzueR: use be quiet! BN299 more than year |
