We measured the power consumption with the system resting at the Windows 7 desktop, representing idle values.
The power consumption of our entire test system is measured at the wall while loading only the CPU using Prime95's Small FFTs setting. The rest of the system's components were operating in their idle states, hence the increased power consumption values (in comparison to the idle figures) are largely related to the CPU's individual power usage.
Power consumption was also recorded while playing Battlefield 3, representing gaming values.
Efficient and advanced electrical components, such as gold capacitors and a 12+2 power phase, allow the ASRock 990FX Extreme9 to deliver clean power to the AMD FX-8350 processor, resulting in a low idle power usage at stock frequencies.
The high-end electrical components also allow the ASRock 990FX Extreme9 motherboard to overclock the FX-8350 processor to 4.6GHz, without its power usage increasing significantly.
Great motherboard, they deserve to be recognised more in the enthusiast sector. I love my ASROCK Z77 board
Nice look board and excellent overclocks. I want to upgrade my AMD system this year, but have been waiting on the new products.
It is a little expensive IMO for what you get, Intel boards start way under £100 today.
Great board, sexy layout and well featured. BUT as overclocker i feel 1.5v core is just too much, even for AMD CPUs…. The marginal gains that you get from 600mhz for about 0.3 vcore increase is not worth it. For 5.0ghz, is ok, 1.5 vcore would be understable, but going upper than that is just too away from my comfort zone. I dont know if I can blame the board or a bad chip. Good review !
The Extreme9 990FX will do very well with a 8370E. Does good enough with 9590 (I call the lazy overclockers board combo). Don’t expect it to overclock the 9590 much. It does run all 8 cores at 4.9 ghz all day with turbo turned off (a little better than 4.7/5.0 stock setting for most things). Recognizes the Avexir 2400 speed ram and sets it automatically. Just make sure you have room for a big twin tower air cooler.or a least a 240mm water cooler so you can keep that temps down.
It does very well with crossfired R9 285s OC to 1100 Mhz (water cooled also).
If you are going to do something likes need a big case and big power supply too. Like around 1100 watts. 285/380s need a lot more cooling to push them over 1000Mhz
