Hardware Secrets and KitGuru have reviewed Corsair's latest AX750 and AX850 modular power supplies.

Let's see what they had to say:

  • Hardware Secrets:

    "The new Corsair AX850W is an outstanding power supply. During our tests it achieved very high efficiency, peaking above 90%, voltages very close to their nominal values (3% regulation instead of the traditional 5% regulation), extremely low noise and ripple levels, and a more than adequate number of connectors for an 850 W product. On top of that, due to its highly overspec’ed components, we could easily pull 1,000 W from it (even though efficiency dropped a lot under this scenario)."

  • KitGuru:

    "The AX750 is the third Corsair AX power supply we have reviewed and it has reaffirmed our opinion that the Professional Series Gold power supplies are the finest on the market, bar none.

    The 750 model is finished to the same exacting standards as the AX850 and AX1200 and we love the understated design and simple aesthetic appeal. This PSU will look great in any system, regardless of lighting or internal structure.

    Inside, the components used in the product composition are as good as you will find … independent DC output boards, double sided PCB and zero voltage switching to help raise efficiency and improve overall thermal performance. These claims are not just PR fluff as our testing shows how good the thermal performance and efficiency are – the unit manages to maintain over 90% efficiency throughout the full range which is not an easy goal to achieve."

These are the two best power supplies in their respective wattage ranges, period.
