On the front of the package is a quarter-shot of the PSU, with the modular panel exposed. Near the bottom-right side is the model description, and right above it, two badges depict the 80 PLUS Gold efficiency and the product's seven-year warranty. On the front, bottom side, a brief, multilingual list shows the most interesting features of the PSU. In addition to the Gold efficiency certification, this includes the platform's semipassive operation, exclusive use of Japanese capacitors and good performance levels.
On the top of the box, Corsair provides information about the available connectors and the cable length, something that we found very useful. However, in the end, we always measure cable length on our own to confirm the data that the manufacturer provides. Finally, on the rear side, two graphs depict the fan and efficiency curves, and a table shows the power specifications. You will also find the unit's dimensions on this side.

As usual for a Corsair high-end product, adequate protection is provided inside the package by a couple of thick foam spacers. In addition, the PSU is stored in a nice cloth bag.

The bundle includes a nylon pouch, which will come handy for storing the unused modular cables. The other accessories include several zip ties, a set of fixing bolts, an AC power cord and a case badge. Finally, you will also get a user's manual and a warranty leaflet.

A sticker on the front of the PSU informs future owners that at light and mid loads, the fan won't spin. Corsair apparently didn't want some users, who aren't familiar with PSUs featuring a semipassive mode, to believe that their shiny, new PSUs were defective once they noticed the fan didn't spin.

On the front, the classic, honeycomb fan grille is used, and the small on/off switch is located next to the AC receptacle. This is installed vertically instead of the typical horizontal mount. On the sides, two large decals show the model number, while the power specifications label can be found on the bottom.

The modular panel doesn't include many sockets, since this PSU features only four PCIe connectors and a single EPS. The characteristic design of the fan grille, with the parallel lines, is used on all Corsair high-end models, and it makes them stand out from the crowd. This fan grille design looks nice, but the remaining exterior section of this unit is rather boring. Finally, the dimensions of the RM750x are quite large for a PSU of this capacity, and we believe that in the future Corsair should offer a more compact version.
Cabling

- cable7
- cable4

The cables are stealth, meaning that they consist of darkened gauges. The ATX, PCIe and EPS cables feature solid capacitors, which help in ripple suppression. The remaining SATA and peripheral cables are flat, in order to block less airflow inside the chassis.

They have a 650x as well that's a little cheaper.
Wrong on so many levels.
YOU do not have the failure rate for this or any other Corsair PSU.
This PSU is the RMx, not the RM, so even if you did have a failure rate, it would only be about two weeks of data.
If you were talking about the RM and not the RMx, and you actually had failure rate data, you would see that the failure rate on the RM wasn't really high at all.
*sigh* nonsense comment of the day.
I don't know if this is a problem of your site, or my PC/IP, but frequently the charts do not load, even when the page "ends" loading.
Sometimes, if I "reload", then the charts also load.
I open all the article pages simultaneously, on different tabs, so I don't need to wait for each one to load.
Did you even LOOK at the article? The only problem with these are the Sinopowers on the secondary side, and that's not even a "bad" thing. Oh and btw, some of the best power supplies in the world are Superflower OEMs produced by Corsair.
Permanent'ing such thing from the editorial side would be great!
Corsair doesn't use SuperFlower anywhere in its lineup. CWT, Great Wall, Flextronics, Seasonic and Chicony which has since been dropped are all the OEMs Corsair uses or has used.
Tier lists will include an entire product line in a category based upon a single model review. The Corsair HX 750/850 were great, the 1000 / 1050 were dogs but all were placed in the same tier. Below we see that CWT made their lowest tier as well as some of the best products Corsair ever sold.
CS was made by Great Wall
CX and GS by CWT
VS by CWT
RM 450-650 were made by CWT,
RM 750 and 850 by Chcony
RM 750v2 -850v2 and 1000 were made by CWT
RMi / RMx series are made by CWT
HX 650 was made by Seasonic
HX 750, 850 and 1050 were made by CWT (2/3 were excellent)
HXi series was made by CWT
AX series was made by Seasonic
AXi was made by Flextronics
Wrong. The AXi is a SuperFlower Leadex OEM. Which is sometimes produced by Corsair, Seasonic, and EVGA.

And why would Seasonic make a SuperFlower platform? They don't. The 2 companies are direct competitors. You are correct about EVGA using SuperFlower though.
They were?!?!?! Says who???
The guy who gave it a 8.5 performance * and 7.0 Build Quality rating
http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story5&reid=245
The 850 got a 10 in performance but back then no BQ ratings
http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story5&reid=153
* 1000 wasn't that bad with a 9.0 performance rating. I used it 3 times as I recall, had problems with 2..... one would hiccup under SLI loads, a user build had fan noise issues.
Right. And if you read the fine print:
"More loose heatsink screws to deal with. But at least there were only two of them in there this time that could be considered a potential problem. Two points off for that. It'll probably never be a problem for 99% of these sold, but I'm an electronics tech. I get to be picky with stuff like that."
This doesn't make a product "a dog".
AFAIK, it really wasn't a problem for 99% of the folks out there and since it was pointed out in the reviews, CWT started using nylon washers or thread lock on all screws.
I did read the fine print, but I am speaking "in context" ... As you said ... 2 points off... that only brings it to a 9. In the general context of things, I normally would call a 9.0 build quality rating a dog.... perfectly acceptable, perfectly suitable for an office or budget restricted gaming box.
But when one is looking at, and prepared to pay for what the HX series bought to the table for a presumed moderate to higher end build for overclocking or gaming, the mindset is "top end".
I expect a 10.0 here. When you are paying 10.0 quality a prices, a 9.0 BQ / Perf. rating is gonna get a "dog" label, at least in my eyes. If I wanted 9.0's, I'd look at cheaper model lines. As a TX, and without the careless assembly, the moniker would not have been used.
