Corsair AX1600i PSU Review

Inside the box - A 1600W PSU is this small?

Inside the box

From the outside, the Corsair AX1600i looks like most other consumer-grade power supplies, showcasing its efficiency rating, warranty and feature set clearly to prospective buyers. The AX1600i offers 80+ Titanium Efficiency, a 10-year warranty and support for both Corsair's Zero-fan technology and Corsair Link Digital software, making it one of the most efficient and feature-rich power supplies on the market. 

The 80+ Titanium certification is the highest that any power supply on the market can achieve, making this power supply one of the most efficient in the world, at least on the consumer market.

Opening up the box we found a PSU that was surprisingly compact, measuring in at 20mm shorter than our AX1500i, making this unit almost 10% smaller, a huge difference considering the fact that this PSU can push 100 more watts of power and is lauded as being more efficient by Corsair themselves. 

While this unit is by no means small, it is undoubtedly an impressive unit when considering its power to volume ratio. This power supply does deliver well over 1200 watts of power after all. 

We see the same external aesthetic as Corsair's other AX series power supplies, with a grey/black aesthetic, though note that Corsair does give users the ability to add a little splash of colour to the unit, which you can see in some of the images below.

Moving to the rear of the unit we can see that Corsair offers an insane number of possible cable connections to this unit, allowing users to attach a lot of devices to the AX1600i. 

It is hard to imagine Corsair even having room to attach more cables to the unit, as there is barely any space between connections as it is. A list is available at the bottom of this page which showcases the exact cables that come with this unit.

On the top of the unit, we can see a beautiful Corsair embellishment, making the AX1600i quite attractive in a fan-down configuration in most modern PC cases. The lack of a rating sticker here is a welcome change, as this has traditionally forced us to mount our PSUs in a fan-facing-up configuration in cases without a PSU shroud.

Sadly, the rating sticker has to be included somewhere, but Corsair does give users an opportunity to address this issue with magnetic AX1600i covers, which can be placed on either side of the unit to give this PSU a much more attractive aesthetic. 

The included colour options are red, blue and white, which will be enough to suit most colour schemes, while also preventing modders from voiding their warranties by removing or permanently covering these ugly stickers.

Below we can see a colossal version of Corsair's usual cable bag, with every gable type being compartmentalised for easy use. All of these cables have black wires and most of the major cable bundles are covered with a coverall-black braid. 

More information regarding these cables, including their length and a total number of each connector type, are available in a table at the bottom of this page.

Corsair has also decided to ship this unit with four reusable cable ties, which will come in very handy given the sheer number of cables that this unit ships with.

Wow. Overkill 3D is back

Fantastic unit. Amazing how similar it looks inside to the AX1200, only it's got a third even bigger capacitor in it Quote

It's impressive what they've managed and it's good to see GaN making it to the consumer space but it's a shame they used the Transphorm parts when EPC and GaN Systems parts are objectively better in a number of ways.Quote

The AX1600i is a great addition to the Corsair line up.

It would be nice to see a 2000W or higher version as there is a need for it.

The amount of power my 7980XE @4.8 and mGPU can use is silly numbers, it would be nice to be able to power it with a single PSU.Quote
