Performance-wise, this is not a bad entry-level 600 W unit, with voltages inside the allowed range all times and noise and ripple levels always below their maximum allowed values. We saw efficiency peaking 85%, which is not bad at all for a low-cost power supply, but at full load efficiency dropped to 77.6%. One funny thing is that at the manufacturer’s website they say the maximum efficiency is of 80% or 82%, depending on the part of the text you are reading.
The main problem with this power supply is the reduced number of connectors. With only one video card power connector, you won’t be able to directly install a video card that requires two power connectors. Of course this installation is still possible if you install an adapter to convert a standard peripheral power plug into a video card power connector (PEG). The presence of four SATA power connectors on a single cable is another major problem.
Of course there are better 600 W power supplies out there (e.g., OCZ ModXStream Pro 600 W), but they cost more.
