great model, love it
18 September 2019 
Excellent low-cost five hundred from a cool manufacturer. Bought to replace a broken power supply. Installation in the Aerocool PGS VS-4 case went without a hitch, with the lower location of the cable length was enough (case height 495 mm). For a relatively low price, we get a lot of goodies: 80 PLUS Bronze certification, active PFC, two 12 V lines and a set of all necessary connectors for a mid-range system. I want to note the very quiet operation of the fan. Even under load, it is faintly audible, and without load, to hear it, you need to bring your ear literally close. It is not possible to independently check the voltage stability along the lines during the load, but according to the reviews on the network, everything is fine with this and does not sink below 11.6. Well, a few words about the assembly itself: everything is very well done, the weaving of wires is neat, you can’t even immediately determine that this is a low-cost power supply unit. At the moment, it pulls i5-2500k with a slight overclock and GTX 970. The consumption of such a system at the peak is no more than 400 watts, the same PSU will give its honest 500 watts if necessary. In general, be quiet! really well done, they created an excellent, inexpensive and productive line of System Power 9. I am very pleased with the power supply, I think that it is better to throw in a little money and still buy be quiet !, and not some ultra-low-cost Chieftec.
Excellent value for money

This model is worth considering for purchase.

I took 700 W for 5,200 rubles, I think that I couldn’t find a better one for myself, there are no complaints, I hope there won’t be any)
I can’t say anything about the technical station, but the appearance and material are of high quality, black braided wires along their entire length, ideal for looking beautiful in the case, flexible wires
It’s a pity that it’s not modular) The extra wires had to be stuffed under the box, and there are quite a few of them here)
