Introduction and Features



Corsair is a well-respected name in the PC industry and they continue to offer a complete line of products for enthusiasts, gamers, and professionals alike.  Today we are taking a detailed look at Corsair’s latest flagship power supply, the AX1600i Digital ATX power supply unit. This is the most technologically advanced power supply we have reviewed to date. Over time, we often grow numb to marketing terms like “most technologically advanced”, “state-of-the-art”, “ultra-stable”, “super-high efficiency”, etc., but in the case of the AX1600i Digital PSU, we have seen these claims come to life before our eyes.

1,600 Watts: 133.3 Amps on the +12V outputs!

The AX1600i Digital power supply is capable of delivering up to 1,600 watts of continuous DC power (133.3 Amps on the +12V rails) and is 80 Plus Titanium certified for super-high efficiency. If that’s not impressive enough, the PSU can do it while operating on 115 VAC mains and with an ambient temperature up to 50°C (internal case temperature). This beast was made for multiple power-hungry graphic adapters and overclocked CPUs.

The AX1600i is a digital power supply, which provides two distinct advantages. First, it incorporates Digital Signal Processing (DSP) on both the primary and secondary sides, which allows the PSU to deliver extremely tight voltage regulation over a wide range of loads. And second, the AX1600i features the digital Corsair Link, which enables the PSU to be connected to the PC’s motherboard (via USB) for real-time monitoring (efficiency, voltage regulation, and power usage) and control (over-current protection and fan speed profiles).

Quiet operation with a semi-fanless mode (zero-rpm fan mode up to ~40% load) might not be at the top of your feature list when shopping for a 1,600 watt PSU, but the AX1600i is up to the challenge.

Corsair's ML120 and ML140 Pro RGB fans connect physically to the Lighting Node Pro or RGB hub, allowing you to use Corsair's Link software to program animated RGB lighting inside your case.  The price of these fans sets a high bar for them to meet, a three pack of ML120 Pro RGBs with the RGB Hun and Lighting Node Pro will cost you $120 or a two pack of the ML140s plus controller runs you $100.  The Tech Report tested the fans against CoolerMaster's MasterFans and were quite impressed, Corsair's fans provided more effective cooling performance as well as being significantly quieter.  If you are in the need for high end RGB fans, this is a decent investment but you really have to need them.


"Corsair's ML120 Pro RGB fans pair an innovative magnetic-levitation bearing with RGB LED lighting for a fan that's both functional and flashy. We put a trio of these spinners to the test to see whether their performance matches their good looks."

You have already seen Ken's review of the Corsair One Pro, but there was something he didn't have the guts to do; rip it open and expose its innards.  The Tech Report were not that squeamish and risked cracking open the machine to see what the layout inside was.  The news is good and bad, the components are squeezed into an impressively small space and the layout is very effective at cooling in such a confined space.  However it is not easy to swap out components, the watercooling hoses are so short the case cannot be fully opened without disconnecting them and while you could add in an M.2 drive, you need to completely remove the GPU to get at it.  Drop by to take a look at the titillating pictures and see what The Tech Report thought of this compact gaming powerhouse.


"Corsair's One Pro promises full-fat desktop performance from a system much smaller than most off-the-rack Mini-ITX PCs. We turned up the heat on the One Pro to see whether Corsair's liquid-cooling know-how can really shrink full-size desktop performance into a 13-liter package."

Despite its surprise launch a few weeks ago, the Corsair ONE feels like it was inevitable. Corsair's steady expansion from RAM modules to power supplies, cases, SSDs, CPU coolers, co-branded video cards, and most recently barebones systems pointed to an eventual complete Corsair system. However, what we did not expect was the form it would take.


Did Corsair hit it out of the park on their first foray into prebuilt systems, or do they still have some work to do?

It's a bit difficult to get an idea of the scale of the Corsair ONE. Even the joke of "Is it bigger than a breadbox?" doesn't quite work here with the impressively breadbox-size and shape.

Essentially, when you don't take the fins on the top and the bottom into account, the Corsair ONE is as tall as a full-size graphics card — such as the GeForce GTX 1080 — and that's no coincidence.

Corsair Updates Link to Support Windows 10

Subject: Cases and Cooling | August 1, 2015 - 07:01 AM |
Tagged: windows 10, Corsair Link Digital, Corsair Link, corsair

Quick Note: This update does not support “the original Corsair Commander”. If your system uses that internal peripheral, then you should wait for a later version.

About two weeks ago, I decided to purchase and install a Corsair H100i GTX cooler in my system. While it runs quiet and keeps temperatures decently low by default, the device supports Corsair Link to re-balance the fans and pump, as well as change the color of the LEDs in the Corsair logo. For the record, my cooler will be staying on default white, although I can see people with existing color schemes wishing to match or contrast them, and it is great that Corsair provides that functionality.


At the time, it was not compatible with Windows 10. The operating system blocked the application's attempt to run, and even pushed notifications to my desktop to let me know it can't do that, Dave... I mean Scott. I changed the file name and was able to get the system tray notification to work, but entering the windowed interface caused it to crash.

As of July 28th, Corsair released a fixed version that runs on Windows 10. Corsair Link 3.2.5676 is available from their website, but it did not seem to get much publicity. Part of this might be because, by the time the general public got a hold of Windows 10, which started the next day, Corsair already had functional software out. Still, if you were a Windows Insider and you are still waiting for a compatible version? It came out last Tuesday.

Revisiting the Corsair AX1500i

Tagged: Digital Power Supply, Corsair Link, AX1500i, 80 Plus Titanium

It has been almost a year since Lee reviewed the Corsair AX1500i, one of the best high wattage PSUs it has been his pleasure to test so it seems appropriate to remind you of it's quality with this review from [H]ard|OCP.  While the PSU is not new and still costs more than the competition at $400 the 7 year warranty is better than most.  The review is of two Corsair AX1500i PSUs, one provided by Corsair and one purchased from a retail outlet for reasons you can read about in the full review.  In the end [H] gave this PSU a pass, they felt that the unchanged price was a strike against Corsair as are the claims of the marketing team but as far as performance this PSU provided solid power in even their torture tests.


"It is not every day that a company has the moxie to come out and say that it makes "the best" of anything, but that is exactly what Corsair is saying about its AX1500i computer power supply; "The best enthusiast power supply you can own." Of course that begs one question, "Is it, or isn't it the best enthusiast PSU you can own?" We answer that."

Corsair's HX1000i is good, but not quite great

Subject: Cases and Cooling | October 21, 2014 - 02:26 PM |
Tagged: modular psu, HX1000i, Corsair Link, corsair, 80 Plus Platinum

Corsair have updated their high end and high powered PSU line with the HX1000i, developed once again with CWT and sporting an 80 PLUS Platinum rating and Corsair Link integration.  The documentation is a little confusing, referring to a single 12v rail rated at 83.3A or 1000W but also mentioning it can be toggled to multiple 12V rails, not to mention the small rounding error in their math.  The actual PSU is very well constructed and passed all of the tests that [H]ard|OCP's torture chamber required of it; just not to the same level that the older HX1000 unit managed.  That is a little disappointing as you would hope that the quality would improve over time but it is in line with the competition and certainly not a bad showing, merely not what [H] had hoped for.   It is still worth your consideration so make sure to read through the whole review to see if the HX1000i meets your needs.


"Corsair's HX series represents its "second tier" line of enthusiast computer power supplies, but its new HX1000i does take the top spot when it comes to its ~1000 watt power supplies that are Platinum certified and fully modular. Let's see if this latest addition from Corsair represents its quality pedigree of days gone by. "

Introduction and Features

Corsair recently released three new HXi Series Fully Modular power supplies: the HX1000i, HX850i, and the HX750i. All three power supplies are 80 Plus Platinum certified and support the Corsair Link digital interface. Corsair continues to offer 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. In this review we will be taking a detailed look at the HXi Series 1000W fully modular power supply.


All three of the new Corsair HXi Series power supplies are optimized for silence and high efficiency. Zero RPM fan mode means the fan doesn’t spin until the PSU is under heavy load, and the fan itself is custom-designed by Corsair for low noise operation even at high loads. Flat ribbon-style black cables are fully modular to facilitate fast, clean builds.

The Corsair HXi Series is built with high-quality components, including all Japanese electrolytic capacitors, and is guaranteed to deliver clean, stable, continuous power, even at ambient temperatures as high as 50°C. HXi Series users can also install Corsair Link software to monitor power usage, efficiency, and fan speed.

80 Plus Platinum: High Efficiency – Low Heat HXi Series PSUs are 80 Plus Platinum certified, making them among the most efficient on the market. With efficiency of at least 92% at 50% load, your PC will remain cool and quiet, potentially saving money in the process.

Corsair Link Ready While the HXi is an analog power supply, it features a built in analog to digital bridge to communicate vital information to the Corsair Link software via USB. This allows the user to monitor and log fan speed, current and voltage of the +3.3V, +5V, and +12V rails, monitor power out, display power in and efficiency, and enable/disable OCP on the +12V rails.

Zero RPM Fan Mode offers silent operation at low to moderate loads. Thanks to a highly efficient design, the HXi Series power supplies generate minimal heat and are able to operate in a silent, zero RPM Fan Mode for up to 40% of the PSU’s maximum load (at 25°C room temperature). This means the HXi power supply can be completely silent while the PC is performing less intensive tasks. As the load and temperatures rise within the PSU, the thermally controlled fan gradually spins up for quiet operation even during more demanding computing.

Optimized for Low Noise Corsair continues to branch out beyond memory and power supplies and is paying close attention to fans and their applications. Within a PSU, the most important feature of a fan is high static pressure, allowing the fan to push air through the relatively high density of components. The NR135P intake fan was specifically designed to move more air through the power supply components with less noise. Fan blades are properly balanced to prevent resonance at higher RPMs and the fan features fluid dynamic bearings for quiet operation and long life.

In addition to the specially designed Corsair cooling fan the components on the HXi Series PCB are laid out to allow air to easily flow between them. The HXi PSUs also include fully modular cables made flat for easy installation and reduced airflow resistance.


Corsair HX1000i PSU Features summary:

•    1,000W continuous DC output (up to 50°C)
•    7-Year Warranty and Comprehensive Customer Support
•    80 PLUS Platinum certified, at least 92% efficiency under 50% load
•    Corsair Link ready for real-time monitoring and control
•    Fully modular cables for easy installation
•    Flat ribbon-style, low profile cables help optimize airflow
•    Zero RPM Fan Mode for silent operation up to 40% load
•    Quiet fluid dynamic fan bearing for long life and quiet operation
•    High quality components including all Japanese electrolytic capacitors
•    Active Power Factor correction (0.99) with Universal AC input

Corsair's quiet HX1000i PSU could be with you for a long time

Tagged: PSU, corsair, HXi Series, HX1000i, kilowatt, 80 Plus Platinum, Corsair Link

Before even delving into the specifications there are two very attractive features about the Corsair HX1000i modular PSU, it has an 80 Plus Platinum rating and a 7 year warranty.  The 12V rail is capable of delivering 999.6W @ 83.3A and once a small bug in Corsair Link is solved you can actually program the PSU to either provide a single 12V rail or multiple rails.  With eight 6+2 PCIe power connectors you can power even the most demanding of video cards and the dozen SATA power connectors also make it perfect for those with a storage fetish.  At $230 it is not that expensive for a PSU of this power and one of TechPowerUp's favourite things about the PSU was the quiet performance even under load.  Check out the review to get the full picture.


"Corsair just introduced the new HXi series, comprised of members with Platinum efficiency and full compatibility with the Corsair Link software. Today, we will take a look at the second-strongest unit of the line with 1 kW capacity, ideal for a power-hungry system with up to four VGAs."
