Corsair AX760 Power Supply Review
The +5VSB Power Supply
Contents
The +5VSB (a.k.a. standby) power supply is independent of the main power supply, since it is on continuously.
On the AX760i, this power supply is located on a separate printed circuit board, whereas on the AX760 this circuit is located on the main printed circuit board.
The +5VSB power supply uses an ICE2QR4765 integrated circuit, which incorporates the PWM controller and the switching transistor into a single chip.

The rectification of the +5VSB output is performed by a PFR30L50CT Schottky rectifier, which supports up to 30 A (15 A per internal diode at 125° C, 0.54 V maximum voltage drop).
