Interesting to know....cheers.

Thanks mate, I will just make do with the USB connected from psu to motherboard. Yep the HX850i and AX860i are totally different internals. so I suppose the extra cable is supplied just in case needed. I am not going to fork out some £48 for the Commander thingy, and the Link software shows me what the PSU is up to. I was just curious. :D:

Update, the replacement HX850i PSU arrived yesterday, so out goes the RM550X (back into storage) and installed the new one. All is fine so far....:D: However, one question: With the cables is the USB cable to connect to the USB port on the PSU and then into a USB2 port on the motherboard for the Link software to monitor. But, there is another slim cable where one end would connect to the digital port on the PSU, but I cannot find where the very small connector on the other end is fitted to ? Would it be used to connect to the USB Dongle as supplied with the AX860i, which I don't have, and would (if I wanted to) I have to buy this separately to use this cable ? Not sure why this cable is supplied if I don't have anything to plug it in to....:D: Unless I am missing something....:confused:

Corsair great service as usual have offered me an HX850i as a replacement RMA PSU. I have accepted and can't complain about that ! Although it is a cheaper model, I don't care about that, and hoping that this model by a different manufacturer will play nicely with my Gigabyte motherboard. Great stuff Corsair. :cool:

Yep, my 3rd one failed, and I am not going to RMA for a fourth...:biggrin:

Just to chime in.... I built my PC last April: Phanteks Primo case. Corsair AX860i PSU Intel i7 6700K (stock) - BIOS now F21 Gigabyte Z170X Gaming G1. Corsair LPX Vengeance 2 X 8GB modules. EVGA GTX980Ti. Samsung 950 M.2 Nvme 256GB X 2 modules. Intel 750 400GB Nvme SSD Samsung 850 250GB SSD Plus a couple of WD HDD's for various things... Now, the PSU went into the boot loop sequence after a couple of months, so removed it and installed my old HX620 and it ran just fine. Then replaced that with a new RM550X and the PC again ran with no bother. I RMA'd it back to Scan Computers, and received a new replacement about a month later. Installed that, and it ran OK for a few months before the boot loop kicked in. So had to put the RM550X back in, and all was fine again. This time I contacted jonnyGuru in his forum, and he arranged for another RMA back so that he could try to find out what was wrong. Initially they found no problems, until the got the exact same motherboard as mine, and then it played up. I received my 3rd replacement PSU a couple of months ago, and yesterday it booted to the desktop, froze, and had to shut down the PC using the power button, and then when it tried to reboot, I switched off the PSU. Back in went the RM550X........again. So far I have got through 3 PSU's, and a bit pointless in doing another RMA because I expect the 4th one would then get grumpy after a couple of months or so....:(: I like Corsair PSU's and in my 'old' 2009 PC I did have the initial HX1000 pack up after a couple of years, and got a HX1050 as a replacement, which is still going fine since then, and handy to use for the internet should I have any problems with this 'new' one. I guess I will have to live with the RM550X (hopefully for quite some time) but may replace that with a slightly higher wattage PSU later on, as I prefer to have two separate power cables for my 980Ti rather than the one which is split into 2 x 6+2 connectors. It seems that this PSU does not like Gigabyte motherboards, or especially mine in particular. :D:
