XFX Black Edition 850W review
'XFX entrusts the cooling of their first PSU to an Adda 135mm ball bearing fan. Adda’s fans are amongst the most reliable you can use nowadays, which justifies XFX’s selection. The 135mm ball bearing fan has a maximum rotational speed of 2050RPM, at which speed it creates air flow equal to 89.3 CFM and noise equal to 37.8dB(A). That would be a lot of noise for home systems but this fan is controlled by a logic circuit inside the PSU and should never rotate anywhere near its actual maximum speed.'
'
XFX chose Seasonic to be their OEM partner and it appears that Seasonic have returned with one of their finest base designs. After opening the chassis of the Black Edition we easily noticed that
it is based on the same design as the extremely popular M12D unit.' (@žile, pogodio si

'The primary capacitors both are industrial grade Nippon Chemi-Con KMR series products, covered by a very sophisticated filtering stage. All of the capacitors over at the secondary side are industrial grade Nippon Chemi-Con products, making this unit an all-Japanese affair. The heatsinks of the unit appear to be rather basic, but larger heatsinks won’t be necessary if this unit is able to perform at its advertised electrical efficiency.'
'
Summary:
By teaming up with Seasonic, XFX have released one of the most impressive products we have ever tested in our labs. Due to the class leading electrical performance, creative design and eye catching styling it is deserving of our most coveted award.'
