Corsair HXi Series Fully Modular 1000W Power Supply Review

Author: Lee Garbutt
Manufacturer: Corsair

Corsair Link Monitoring and Control Software

The Corsair Link feature of the HX1000i allows for a full suite of telemetry to be communicated from the HX1000i to the PC over USB or a Corsair Link Commander Unit (sold separately). After downloading and installing the free Corsair Link software, you can monitor a large range of performance variables, including power input and output, efficiency, fan speed, and internal temperature. You can also configure and customize some features, including selecting fan speed modes and select between single-rail or multi-rail modes for the +12V outputs. But unlike the AXi1500 PSU we reviewed a few months ago, you can't apply selectable OCP trip points for the HX1000i through Corsair Link.

Two interface cables are included with the HX1000i: A Corsair Link USB cable, which allows connecting the HX1000i PSU to an internal USB header on the PC’s motherboard, or alternately, the Digital Interface cable, which can be used to connect the PSU via a Corsair Link Commander. We used the USB interface for testing.

After downloading the software from the Corsair website we installed the Corsair Link software on one of our test PCs running Windows 7.  Note: Corsair Link does not work in Windows XP environments.

Once installed and running, you will be presented with the Corsair Link dashboard, which features tabs across the top for navigation to different screens. The System Tab is shown in the screenshot above. Not only does Corsair Link gather and display info about the HX1000i PSU, it also grabs data from other components inside your PC. All the various component parameters are listed down the left hand side (graphics adapter, CPU, motherboard, HDDs, etc.), which can be dragged over onto the main window representing the approximate location of each component inside your PC.

Selecting the Power Tab takes you to the screen that displays the HX1000i data and allows making fan speed adjustments and selecting between multi rail (default) and single rail +12V mode.

Clicking on the Graph Tab displays a Temperature and RPM graph. You can select as many of your PC’s component devices to track here as you like (fan and water-cooling pump speeds, and numerous component temperatures, etc).

Note: Many other Corsair products also support the Link technology (memory modules, water cooling, case cooling fans and lighting subsystems, GPU Node for monitoring PCI-E current loads, etc.).

I love those reviews where the manufacturer is sending their own product directly. I used to be a prostitute before, sorry, journalist, and this is always the same song. One bad review, and you stop receiving samples. Period. Only real reviews would be if the reviewer spent the website money on this, to be relevant and 100% fair. Anything else is just an extension of a press release. But good job, you should get your RGB keyboards soon to play around with... And maybe they won't ask the sample back... LOL. What a "life".

This is yet another reason why I follow PCPer :)

Granted, that guy was a dick and didn't deserve a serious response, but let's be honest, this "review" was not a review, it was an advertisement. It did not contain a single sentence of criticism or personal opinion.

JonnyGURU's review of the HX1000i:

"Corsair Link, seven year warranty, 80 Plus Platinum... we already know all this stuff."

"Ok... I have to ask. Why on earth does this thing come with three Molex chains? Who is ever going to need twelve Molex connectors? Is it 2004 again? This unit could be better served by four SATA chains and two Molex ones. I'm going to deduct something off the score for this one, I think."

"Hmm... once again, we find that Corsair Link is not able to give us entirely accurate results on either the minor rail loads, the power draw, or the power output. I expect we'll find accuracy improving on those last two items as we go up in power, but it's interesting to me that we now have seen two HXi units fail to keep proper tabs on the minor rail current draw. I'm not too put off by that, however, as you simply cannot get true accuracy on anything costing less than a small fortune."

"Are these the best looking shots I've ever seen? No, they aren't. There's a small spike on the 5VSB rail at power up, while the 12V side of the unit seems like it takes a little time to come up to full power."

"EVGA has been stomping all over everybody lately when it comes to value, and we find their P2 1kW unit sitting at thirty dollars cheaper than this one. Even Seasonic has a Platinum unit this size for cheaper, though only by ten bucks. In fact, there are only two units more expensive than this one, and not by a lot: the Antec HCP-1000 and Enermax Platimax 1kW. Both of them are ten dollars more than this one. Corsair, I think you need to get this price down some yet."

This is what a review sounds like. Even on a really good unit like the HX1000i, there are always things to pick at. A good reviewer should always try to find these and mention them.

JonnyGURU gets free samples from Corsair as well, so what's with this softball bullshit? If you're going to be paid by Corsair to put up an overview of one of their products, that's fine, just mark it as a sponsored article and don't label it as a review.

So true.

What nonsense. I've seen a lot of reviews both here and on other pro-sites that were quite harsh.

PcPer, as always....great job!

What is the benefit of super good voltage regulation? For instance the ax1500i had a voltage regulation of ±0.1%. How is that more beneficial in a real world sense than the hx1000i's ±2%?

Yeah.....but does it blend?

I'd like to see some comment about what you don't like.

This is common on JonnyGuru and HARDOCP reviews.

After the experience I had with Corsair AX860i and their Corsair Link was noting more then a nightmare. No review will cover what I had to go through with their software and ASUS Software bundle that came with Maximus VII Hero motherboard, put it this way I'll never purchase another Corsair or Asus Product again, and no I don't care what kinda of rep they have.
