CorsairLINK on AX860i query

[Scoob]

Hi all,

I've literally just finished installing my new Corsair AX860i PSU, replacing my older HX750 unit.

So, the first thing I want to play with is the CorsairLINK software of course, cos it shows me STUFF my PSU is doing lol.

Anyway, after some Windows 8 wierdness (apparently that's what causes it) I now have my CorsairLINK 2 software showing me what the PSU is doing - this is up on my 2nd screen so I'm running benchmarks and the like.

So, I have two GTX 570's and I've powered them in the following way. I have ONE 8-pin (PSU) to 6+2 pin PCIe power going to the upper 570, a second going to the lower 570 - so that's TWO PCIe power cables from the PSU used so far. As there are no more of these single leads supplied with the PSU, I next use an 8-pin (PSU) to 2x 6+2 pin PCIe power - so this third PCIe power cable is split over two GPU's.

I think this is an ok way to power things, ensuring each GPU has it's own dedicated line, plus one shared line. So, THREE of my PSU's PCIe power connectors populated.

Now, going into the CorsairLINK 2 software, I see SIX PCIe Power readings shown, 1 through 6.

PCIe 1 - always shows zero
PCIe 2 - usually zero, but up to 12a during benching
PCIe 3 - ditto
PCIe 4 - usually 5-6 at idle, going up a little during benching
PCIe 5 - usually 6-8 at idle, going up a little during benching
PCIe 6 - usually 5-6 at idle, going up a little during benching

I expected to see one of two things.

i) Power draw from THREE PCIe only, as I only have FOUR PCIe power on my 860i, but only THREE are connected - I assume only the 1200i has the full six.

or

ii) Power draw on FOUR PCIe as the PSU knows one of my cables is split to go to two 6+2 pin - though of course my 570's only use 6 pins.

So, those last three showing power draw all the time sorta ties in with i) above, I just don't know why I get readings from two of the others as well during load.

The reason for this is because I'm trying to make sense of the real power draw of my PC and its components. I did a thread previously using my wall socket Power Meter to measure stuff, but that included my (external) loop, Monitor, Speakers, laptop charger etc. as well, so the reading was more.

Anyone who's gotten familiar with this software, well, do chip in as I'm confuzzled.

Btw: during some light benching - just using Heaven 3.0 - I regularly saw a reported 99% efficiency for around 400w load.

Once I understand what the software is telling me, I'll do some proper monitoring Who needs games eh, with all this FUN to be had? *

Caveat: I'm tired, so in all likelyhood I'm being daft.

* Erm, me you boring old fart, you know, the fun inner child you've not let out today!

I will have my rig set up in a few days so if you are still having trouble maybe I can help you figure it out cause i have the ax760i

Hi,

Thanks.

I was using it in Windows 8 and the software caused all sorts of problems. For example, if it's running and I disable SLI my PC craps out. Other apps complain when it's running etc.

I'm back on my W7 build now and yet to re-install it, but will soon.

Oh, I doubled checked things and I had my PCIe power plugged into sockets 2, 4 & 5 on the motherboard, yet in the software 3 & 6 also showed power draw which is not possible. This makes me miss-trust everything it tells me unfortunately.

Let me know how you get on with your software!

Cheers,

Scoob.

Confused the hell out of me here for a while mate.

The connection going into the PSU is irrelevant, so no need to mention '8pin to xxx'. That's just a 6+2 pin cable.

But now I see what you mean.. I would use the split cable (these don't come with the ax1200i btw, or atleast I didn't get any) on a single card and use the other two on the other card.

As for corsair link I don't use it because it seems to be gimmicky guff. I installed it with the intention of setting a custom fan curve for the ax1200i and it couldn't even do that so I chucked the kit back in the cupboard.

Hi NRG!

Yeah, sorry, I llikely wasn't too clear on that. I was just trying to explain how the PSU has 6x 8-Pin PCIe power connectors, only three of which I used despite needing FOUR 6 pin PCIe power for my GPU's.

I'd have preferred FOUR separate 8 Pin cables personally, rather than just two - seems a bit daft.

So, you think the two individual 8 Pin PCIe's should go to ONE GPU, and the split 8 pin to the other? I will try that.

I was quite keen to check out the monitoring stuff myself - erm, really not sure why lol.

Yea I understood the cabling system you had fine once I'd got round the 8 pin thing haha.

The ax1200i comes with 6 plain 6+2 pins, didn't realise the ax860i had one of those split cable jobbies..

I just decided to try out the software one day and it was off the pc again within about half an hour lol.
