XFX PRO 750 W Black Edition Full Modular 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.
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 an SBR30A40CT Schottky rectifier, which supports up to 30 A (15 A per internal diode at 110° C, 0.50 V maximum voltage drop).

Man I wanted to leave a comment on this psu, It’s been running strong since I purchased it around 13′-15′ iirc. It has been in multiple systems, currently powering a 3700x + 6800xt and some ssds one hdd and couple of nvme drives. I am genuinely surprised/happy at how long it has lasted and it’s still going! Potentially it will last till my kids are old enough for a pc!
Probably my finest pc part selection I’ve ever made.
Will be getting a seasonic for my next psu since XFX stopped making psu’s.
