Final thought and rating
Available for just under £100 and therefore priced at the higher end of the spectrum for a 680W power supply, German manufacturer be quiet!'s E9-CM-680W is a well-thought-out unit that ticks practically all the boxes.
Aesthetically rather lovely to look at, for a PSU at least, and enabling easy-as-pie integration through the common sense inclusion of colour-coded ports, this Straight Power model is geared towards near-silent computing via the inclusion of the well-engineered SilentWings 135mm fan.
We believe the PSU market will see considerably more focus on mid-wattage supplies such as this be quiet! Intel is reportedly dropping the TDP on upcoming desktop Ivy Bridge chips and the rumour-mill suggests NVIDIA's high-end Kepler GPU may draw less than 200W at full chat. What users need, then, is a top-notch supply that zeroes-in high efficiency, lots of 12V power and flexible connectivity.
Perhaps the only blot on the scorecard is the slightly high ripple when pushed and the £20 premium when compared to decent 650W PSUs from all and sundry. No supply is perfect, but this one's very good in most respects.
The Good
Super-easy installation
High specification
Very quiet under load
The Bad
Ripple can be a tad high
Cheaper main cap than FSP Aurum CM
