Bought this power supply hoping for quiet operation. Upon connection, a squeal appeared. Got a defective unit, was very surprised and upset by this. The next day, took it back to the store. - Truly quiet operation - Modular - Long cables - Stiff wires - Loud sound of the switch when turning the computer on or off.  Viktor: use be quiet!

Ordered on F.ua. 750 watts[283]. Everything is fine, it came new in sealed packaging via NP. Quiet, the relay click is inaudible in the room (it is very quiet on its own). Haven't given it a proper load yet, don't have the means, it's in a PC with a load up to 350 watts. The 12V, 5V, and 3V lines do not sag, the values are stable with a margin. I'll add a comment later after installing in a new computer. Quality, modularity+-, it weighs normally :)), Completeness+-, length and number of cables. Power around 700 watts. I was ready to pay this money for it, the most important part in a PC. The instructions are not clear. All the sockets are marked in their own way, but there is no clear information on them in the instructions, I had to google ... in fact, nothing complicated. Why the metal braid is unclear, tight.

I bought a Gigabyte G750H to replace it for my assembly and went nuts from the level of silence that this power supply shows. Well done Germans, they did everything very high quality inside and out. Long connection wires allowed me to lay cables in a way that the previous PSU did not work out. Long-awaited silence, long cables, fully modular -  Alex Chugaev: use be quiet! BN283 less than month |
