Corsair Professional Series AX760i and AX860i Review

The AX760i incorporates a high grade Yate Loon Fan (D12BH-12) measuring 120mm. This is smaller than the D14BH-14 (140mm) which is used in the AX1200i. These fans use ball bearings and seven fan blades. The maximum rated speed is 2,300 rpm at +12V. These fans have been used in many other supplies over the last couple of years.

The AX760i is a Flextronics design and is packed from edge to edge with several rows of black heatsinks handling heat transfer. The design uses a DSP which reduces the overall number of discrete components. This reduced component count has the benefit of reducing losses in the circuit and helping to improve efficiency. Corsair also say that this reduction helps improve reliability.

The AX760i uses Zero Voltage Switching and Zero Current Switching (ZVS/ZVC) technology to switch at near 0V and 0A.

The AX760i features DC-DC regulation for 3.3V, 5V and 12V rails and secondary side rectification. The supply uses a 4 layer modular connector board PCB to help improve the ground return plane with lower resistance and low voltage drops.
