Not a release board I wouldn't worry about it lol don't think they'd do that on a consumer board

...because if they used a 450 watt power supply, people would be complaining that AMD doesn't even have enough money to use top of the line components in demonstration systems rolleyes.gif

My guess It gives no indication of chip TDP and is an solid PSU. The heatsink should tell you it's completely unnecessary.

Probably for the same reason my rig that only needs maybe 650 watts has a 1300 watt psu.... because why not?

Your sig rig might use 350W. Did you upgrade to BDW-E and SLI Titans?

When you're getting to the point of having the PSU at 30% load when every CPU core and GPU is maxed you actually lose some efficiency from underloading the psu biggrin.gif

Yup. Lots of people who don't understand simple PSU Efficiency curves buy the largest wattage PSU they can afford without understanding they are less efficient than a lesser-wattage, more appropriate PSU.

not for me at least on my AX860. I need to go sub 100w to dip below 90% efficiency. Most good PSU's prob follow suite
