The voltage is 12.17~12.18V which is different with board meterage 12.3V
OCCT Full Speed
The voltage is 12.14V which is lower than idle condition around 0.03~0.04V
You can see no matter idle or OC, 5V is raising 0.1V
There is no 5V dropping 2.26% status in OCCT software.
12V wave is only 0.03~0.04V. Even though itís bigger than default, itís still only 0.33% wave.
These 2 factors are much lower than mainboard meterage.
CORSAIR Professional Series Gold AX750W Conclusion
1.Professional Series new packing and accessories are very good quality
2.CORSAIR provides 7 years warranty
3.Modulized design for better flexibility. The inner capacitors are Japanese made and solid caps.
4.80Plus Gold Certificate and the energy efficiency is 90.80%
5.5V is no dropping in meter test and 12V is only falling 1%. The voltage wave is very small.
6.It supports Hybrid Silent Fan Control technology which fanless below 20% output.
1.Suggesting they can add 6 X PCI-E 6+2 Pin
2.80Plus Gold Certificate and good components make the price be too high
C/P Value ★★★★★★★★☆☆
I used to review Seasonic X-SERIES 750W which is good components and performance Gold product.
You can see CORSAIR Professional Series Gold AX750W should be ODM by Seasonic.
Before, Seasonic ODM PSU has better components than own brand one.
AX750W inner layout is very different with X-SERIES 750W. I think it should be the revised upgrade version.
There are some special parts within my test.
First is the fanless mode in Idle condition. The PSU body temperature is also low.
During CPU/VGA full speed running, fan rpm is controlled by output rate. I donít hear any obvious noise.
PSU body temperature is always below 40 degree C. Itís good control for noise and temperature.
CORSAIR AX750W price is around 170USD.
The key concerns of buying PSU are components, 80Plus Level, price, warranty and brand awareness.
AX750W is high end components level. I think 80Plus level doesnít equal to components.
For the price, many non-modulized or lower components grade PSU price will be much lower.
I hope this review can be reference for the users who want to own a Gold Certificate and high end components PSU.
windwithme will introduce more Gold Certificate PSU in near future. Thanks. :)
