Intel’s Core i7-870 processor reaches beyond 4.0 GHz at 1.45V, allowing us to test each motherboard with nothing more than a large heat sink and fan.

Thermalright’s MUX-120 provides just enough cooling to prevent thermal throttling during our overclocking stability tests at full CPU load.

Kingston’s DDR3-2133 enables our 1.65V DRAM overclocking stability tests and is also capable of running our normal benchmarks at DDR3-1600 using the default voltage.

Now certified by the 80 PLUS organization to meet its Gold efficiency standard, Corsair CMPSU-850HX gives our test rig superb stability under every conceivable load.
