- ATX 12V v2.2/ BTX
- 115 / 230 V 50/60 Hz
- +3.3V@24A, +5V@32A, +12V@55A, -12V@0.5A, +5VSB@2.2A
It's okay, and not 750W 09/04/2013
This review is from: KINGWIN ABT-750MM 750W ATX 12V v2.2/ BTX SLI Ready CrossFire Ready Power Supply
It's made by Super Flower, one of the best PSU manufacturers out there, but this is one of their old low end builds.
The fan is quiet and high quality
Heatsink on the bridge rectifier
Has full input filter including 2 MOV's, so this thing will protect your PC if it is not on a surge protector.
500W power supply. I even looked on the PCB and this design was only meant to go up to 500W, which isn't bad considering its old topology.
Very low quality CapXon capacitors, and this is all the PSU uses.
It uses a very unreliable two transistor oscillating circuit to generate the +5VSB. This method is very inefficient, resulting in lots of heat when your computer is off or in sleep mode, and all the heat is just going to kill those low quality CapXon capacitors even faster. This particular 5VSB also includes what is called a "critical capacitor." If that 47uF capacitor fails, the self oscillating circuit will go haywire and not be able to properly regulate, usually results in frying your motherboard.
You can buy much better for the money. Treat this as an unreliable 500W PSU
