EVGA is near the top spot on our performance charts with the 1000 G7 unit, and this is not an easy feat, considering the mighty Corsair RM1000x that this unit has to face off against. Besides tiny dimensions, the 1000 G7 offers high efficiency, tight enough load regulation, good ripple suppression, and excellent transient response at 12V, which is the most important rail. The build quality is also high, and FSP used top-notch parts, including Rubycon and Chemi-Con caps, along with an FDB fan from a respected manufacturer.
The LED load indicators on the PSU's side are a gimmick, though one that may still come in handy to some. Moreover, PSU downsizing has reached its limits with this product, which is in the SFX-L form factor's territory with only 130 mm depth. Anything less than that will require a smaller fan, and this is not an option if you want to keep noise output low enough. Despite the tiny dimensions, the EVGA 1000 G7 meets the Corsair RM1000x in overall performance, but it loses the fight in noise output because of the smaller fan and the overpopulated PCB. Still, it isn't noisy under normal operating conditions.

Are there cost reductions in making a physically smaller power supply ?
I hope we get to see a review of the Chieftronic Powerplay. It's putting up some interesting numbers.
