Rated 500W (70W 5ch + 150W LFE), I do not believe it, but it looks like it could do a transient 200W. Uses class D and a flyback for the SMPS. Going by the size of the components, I would say not more than 70~100W continuous, as it has no proper cooling for the power supply.
Build quality is above average, but dented by use of Samwha/G-luxon caps.
I give it 6.5/10.
