Final Thoughts and Conclusions
To say we were impressed is an understatement – the Corsair AX1500i Digital has proven itself to be an outstanding power supply! Here are a few of the reasons why:
• The AX1500i is the first PSU we have tested that meets the new 80 Plus Titanium certification standards for high efficiency (and it did it while operating at real-world, elevated temperatures).
• The AX1500i features a Digital Signal Processor (DSP) to provide digitally controlled power. This results in very tight voltage regulation – the best we have seen to date. Having a DSP onboard also contributes to high efficiency, low AC ripple/noise, and reliability (reduced component count).
• The AX1500i Digital supports Corsair Link, which allows the end user to monitor and control component parameters like performance, noise (fan speed), and Over Current Protection (OCP) settings. And many other Corsair products also support the Link technology (memory modules, case cooling fans and lighting subsystems, GPU Node for monitoring PCI-E current loads, etc).
• The AX1500i is one of a very few PC power supplies that can deliver 1,500 watts of continuous DC power while operating on a standard 15A, 120 VAC circuit.
Corsair continues to be recognized as an industry leader for bringing a full line of high quality power supplies, memory components, cases, cooling components, SSDs and accessories to market for the PC enthusiast and professional alike. The Corsair AX1500i Digital ATX power supply delivers very clean DC outputs, with outstanding voltage regulation and efficiency. Under light loads the AX1500i runs in silent, fanless mode (up to ~30% load) and continues to be relatively quiet under normal operating conditions. The AX1500i Digital comes with an excellent assortment of all-modular cables that can support the latest CPUs and multiple, high-end video cards. And let’s not forget the built-in self-diagnostic test feature, active PFC, universal AC input and Corsair’s 7-year warranty!
The MSRP for the Corsair AX1500i Digital power supply is $449.99 USD and should be available through Corsair’s worldwide network of authorized retailers and distributors. Not everyone needs (or can justify) a 1500 watt PSU, but if you do, the AX1500i Digital deserves a very close look!

I would like to thank our friends at Corsair for sending us the new AX1500i Digital PSU to review – thank you and keep up the good work!

lol really minor at this time…
indeed don’t think that someone buys this beast to run it on Win Xp… would be unbelievable 😀
Agreed… very minor!
I
Agreed… very minor!
I almost didn't include it but the issue did come up during my testing as I initially tried to install Corsair Link on one of my old CPU cooler test beds that happens to be sitting next to the PSU test equipment (have retained Win XP environment for consistency over the years). Pretty good PSU if that was the only "weakness" that came up during testing.

Sorry, we had to send back the second R9 295X2 card before the AX1500i arrived to me. :/
Oh ya I remember you
Oh ya I remember you mentioning that. Well maybe someday in the future!

This is the first time I have heard of ATX 12V 2.4. Whats new? I am considering buying a new PSU now I am interested to know.
Good question: according to
Good question: according to our technical expert at Corsair… "The only difference between ATX12V 2.3 and 2.4, AFAIK, is that the 2.4 has the Haswell testing (0 load on the +12V to see if the PSU can support the C6/C7 sleep states)."
It doesn’t meets the
It doesn’t meets the efficiency requirements for 80 plus Titanium for 240v , 80 plus Titanium for 240v at 50% load mute be 96% or higher.
Hi,
I am testing Link
Hi,
I am testing Link software on my machine :
Config:
At IDLE load, PCIe A all current values are shown as ZERO,
Does this software have some threshold, above only it can sense current properly?

would this Corsair AX1500i be
would this Corsair AX1500i be enough for powering two motherboards?
I want to install in a single box Linux and Windows and would need a good graphics card for a 4K monitor
