Hi there ! :D I've just registered and this is my first post here, but I've been visiting occasionally for a long time as this site is a great resource for technical information you can't find elsewhere. Now down to business.
I'm considering buying the Corsair HX750I PSU and want to know the following.
On several sites online (like reviews of this PSU for example) it's claimed that all you need to do is link the USB port of the PSU and your motherboard and install the free Corsair Link softare and voila, you can check or modify various characteristics of the PSU and it's operation.
Elsewhere it says you need some kind of internal hardware thingamajig which connects to the PSU and the motherboard and provides the functions mentioned above as well as many others, which of course costs an additional hefty amount and which I have no intention of buying.
So can anyone who owns any of the Corsair series HX***I PSUs tell me if this function can be used without additional hardware or not ?

I own a AX860i, it is the higher rated version of your PSU, and I can tell you how it works. The PSU has a connection that will be plugged into a USB hub on your motherboard. This is the cable that will come with the PSU:

The cable on the bottom left is the cable for the Link software. The PSU itself has a miniUSB port on it:

That will then go into a USB header on your motherboard like this:

Then all you have to do is install the Corsair Link...

Then all you have to do is install the Corsair Link software from here: http://www.corsair.com/en-us/support/downloads

It will have a interface that you can select monitoring from the fan to the voltage and how efficient it is being. As well you can set fan profiles if you like or keep the standard one.

Hope that helps. Oh and welcome to Toms Hardware.

Thanks a lot, this is exactly the kind of answer I was looking for. Precise, thorough and illustrated.
I really got fed up with getting no answers to my technical questions on the local IT forum I tend to visit (bug.hr), which is a great place to chat about politics, society, gadgets and technology in general, and it even has various guides for noobs (like how to select your monitor for example), but if you ask a specific and complex technical question usually no one even bothers to reply. I think it's due to two reasons - first there's a lot of members but the majority are teens and young people not very technically experienced, and the other is because most of those there who do have great technical expertise are just too lazy to answer (excepting when they're arguing about topics that interest them).
I was kind of worried about this forum when I saw that 2 hours after posting my post had practically no views, but I've seen before that practically everyone on this site eventually gets a satisfactory response. The surprise for me is that on other forums the ratio of views to replies is far greater...
Now if you haven't tired of me droning on, I've got 2 more questions.
The first one is again related to the PSU mentioned above. So let's say I buy the HX750I and plug it in my motherboard and voila. But what if I have no free USB 2.0 headers ? Because I think that will be the case. The motherboard I will most likely buy (Asus Z97 Pro WiFi) has 4 internal USB headers, 2 USB 2.0 and 2 USB 3.0. One of each will be connected to the cables from the front panel of the enclosure (HAF X) which has 2 USB 2.0 ports and 2 USB 3.0 ports. Also one of each will be connected to the 5.25" internal USB hub / card reader I plan on buying, which has 2 USB 3.0 ports and 4 USB 2.0 ports (but only 1 header cable of each type).
So if the internal headers on the motherboard are all used up and I want to use the Corsair link I have three possible choices as I see it.
1. Buy a header Y cable and share 1 header (don't particulary like this idea because the Corsair link might not work from a shared header and 6 usb ports from one header is a bit too much)
2. Buy a USB 2.0 PCI-E card with an internal header (a bit too much money and space for such a simple purpose)
3. Connect the PSU to an external motherboard USB 2.0 or 3.0 port (it shouldn't matter with external ports) in the back with any old USB 2.0 mini B male to USB 2.0 A male cable. Provided the Corsair link works via an external USB port just like via an internal USB header, and I don't see why it shouldn't. The motherboard has an empty space right next to a USB 3.0 rear port which I could use to route the cable back inside the enclosure and then behind the motherboard so it doesn't look ugly :

Do you think solution #3 would work ? Could you maybe try and plug in your's into an external port to test it, if it's not too much trouble ? Or maybe it says it can be done in the manual ?
Secondly, a few questions regarding this forum itself.
I entered this site and registered on tomshardware.COM, and when I click on this thread I'm taken to tomshardware.CO.UK. So maybe I posted by accident on the .CO.UK one, but do the users on the .COM forum see the posts on the .CO.UK forum and vice versa, or are they separated ? Is this site originally american or british anyway ? Are there other TH national sites ?
Also, how do you include images in your post ? When I first made this thread I remember there was some kind of toolbar for inserting smileys and images and such but now that I'm answering your post by having just clicked on "Answer" there's no editing interface whatsoever.
And another thing, when you click to choose as an answer as the proper solution, does that give some kind of point reward to the author (reputation / status), and does it affect how other users see your post (I mean being or not being flagged as an unsolved question or something like that) ?

1. I would not do. Sharing the port might cause issues.

2. Would be the way I would go and connect the USB hub to this and the Link to a port on the board, the less in between you have the better it will work.

3. This can work, I did some research and it looks like some people are able to do this. However they are also reporting that when they restart the PC that they need to unplug and plug in the USB as it doesn't recognize on boot. All you would need is a long enough miniUSB to USB cable.

When you select the answer that best suited you, the thread will be marked as answered and the answer will be highlighted in green to show it was what the OP found to be the most helpful. It does give points towards badges but nothing really serious. Just fun things for your profile.

The site was formed in 1996 by a German Doctor, Thomas Pabst, in the US. We have expanded vastly since then and are ranked in the top tech sites. I can seek the .co.uk forum postings as well as any from other countries.

When you click "Post Answer" it gives you the tools to put the proper tags to insert an image. The tags for an image are [ img]www.website.com/image.jpg [ /img] of course without the spaces. If you put your mouse over the icons on the toolbar up top they will say what they are.

And I am glad what I posted helped. I understand what it is like to have questions go unanswered, I have even gone to professional IT sites and no one would ever post so I would find my own answer. We at THG try our best to help people.

I guess that would depend on the MBO BIOS. I'll have to try and see. If it doesn't work maybe I'll try sharing a header.
If you can recommend a cheap and small USB 2.0 PCI-E expansion card (preferably with no external ports but with an internal header) I would be gratefull. Tried looking for one myself but most are USB 3.0 and have too much of everything.



Nope, checked again and I can see that toolbar when making a new thread but not when replying to one. Maybe it's a browser issue (I'm using Chrome 43).
