Corsair AX760 PSU review - Introduction

Corsair Professional Series AX760 PSU - Platinum Babeeh ...

In this review we test the Corsair AX760 PSU, as abundantly clear a 760 Watt Power Supply grand in performance and efficiency. It's originating froM Corsairs most excellent line of power supplies, the AX series. The one massive 12-volts says it all really. Excellent for multi-GPU solutions and hardcore overclockers. Being slightly more 'regular' non AXi model these power supplies are a bit more affordable, yet remain to be extremely high quality and high performance and an 80 Plus Platinum certification. Yeah, Corsair now offers 760W and 860W versions of the new line of AX power supplies. You may consider these to be the non-digital models based on the Seasonic platforms.

Being based on an Seasonic (excellent) design they are completely different PSUs to the AXi models, though they are still 80 Plus Platinum and fully-modular. The 760W is also fanless up-to 70% load (the 860W to 60%) at 25C ambient, which is pretty impressive (impressive seems to be the word I am using predominantly here). Being Platinum certified this PSU delivers energy efficiency as high as 92%, or better. This results in minimal waste heat, compared to PSUs with lower efficiency, leading to a cooler and quieter PC, in addition to lower electricity utilities bills.

A welcomed side-effect of that design allows the PSU to operate with minimal cooling, and as a side-effect from that ..  very low noise levels. In fact the AX760’s hybrid fan controller technology offers a zero RPM mode at up to about 70% PSU load That is up-to give or take 532W when operating at room temperature (25°C). Noise levels still remain low even when fan speeds start to climb thanks to a quality 120mm San Ace fan from industry-leader, Sanyo Denki.

So yeah, the AX series are all about being top of the line, being quiet and very efficient. The PSU as tested today carries a Platinum certification. Bronze, Silver but really Gold or Platinum is what you want. Efficiency matters; years ago PSUs were as low as 70% efficient, meaning that 30% of the used power simply vanishes somewhere in that electric circuitry, whilst you are paying for it on that electricity bill. Allow me to explain a little more simple, if your components consume 500W directly from the PSU then with that 70% efficient product you'd actually use and draw 650W from your wall power socket. With a Platinum PSU you'd be using 540W. The math is that simple.

The AX760 PSU is 100%  modular, for most of you with a side panel window in their chassis a must really as you'll want modular cables. Even the ATX power connector for the motherboard can be removed. The AX760 PSU is big in performance as well, the one massive 63A 12-volts makes a statement all by itself really. Excellent for multi-GPU solutions and hardcore overclockers as you could hook up three graphics mainstream cards to this PSU. 

All in all we have plenty to show you and test. Mind you that being the Professional range you'll get an added benefit as well, Corsair Professional Series PSUs are backed by an excellent 7-year warranty.

Let's have a peek at the product and then let's head onwards into the review.
