Hardwarecanucks posted a review of the Nexus NX-8040 400W Power Supply
The Nexus 400W power supply performed admirably under all of the high-stress conditions we put it under and it exceeded our expectations in nearly every performance category. The voltage regulation and efficiency are top-notch as is the presentation of the power supply itself. With every cable sleeved to perfection and more connectors than a 400W power supply has any business to possess, the exterior is nearly as impressive as the performance numbers.Nexus NX-8040 400W Power Supply Review
