The first rig I did was the last one I did. I bought the psu with all the cables already connected to the power supply. That sounded like a good deal for a beginner. It was a hugh mess inside the box though with all those connections going nowhere.

So this time I bought a psu without the cables connected to the psu and now I have a big bag full of cables that are very unfamiliar and intimidating.

It's a corsair 850 watt. So with no help from a manual I guess my first step is to see if I can get some help from their web site. Not all web sites I've found are that helpful but I will try.

ha,ha,ha, what fun.

Ah yes,

Intimidating it is, lol. But the good thing is, after you are done..You will remember where they all go...And actually, you probably won't use all of the cables. I was fortunate that a friend of mine helped me to build my first and walked me through all the different cables and where they went. If you need some help, let us know. What kind of MoBo did you get with that PSU?

It's a ASRock Z87 Extreme 4. It's in the case along with the psu. I won't get the cpu until Tuesday. I just went to corsair's web site. What a joke. Well once I actually get started it won't be so bad. I know I need that 24 pin into the motherboard. Ha. Once I look at the diagram of the MB I should be able to start on it tomorrow. I'll be hollering for help I'm sure. Thanks for the call.

--edit

The memory is already in. I bought an inexpensive heatsink/fan that is small and lighter and cheaper than what I was originally thinking. It's a push/pull with 93cm fans. I just hope now that it's not too loud. The ad said not but you know sometimes how that goes. It's similar to one I bought for the first rig. The loud fan noise of that rig was always there whether I was crunching or not. Always loud. So I assumed the noise was mainly because of the case fans. I have a much better case this time with fan controls right on the front panel.

Be talking to ya.

24 pin to the right side looking down at it and a 8 pin at the left upper corner for that MoBo. Most of those cables have labels on them, CPU, PCIe, etc. Just give us a holla...

I got a Corsair PSU and the cables are labeled TXM/HX/AXi only on one end where they would plug into the main unit. It's easy to forget the 8 pin by the CPU. The last computer my brother built wouldn't turn on and the 8 pin was the culprit. The manual isn't the best; I had a question about the Corsair Link USB Dongle but needed to search online for the answer. I have five cables left over.

First thing, before mounting the PSU into the case is to fan out all the leads, and see what the ends say, or if they are unlabled try to match them to sockets on the motherboard, disks GPUs.
Now, keeping the cables fanned out mount the PSU
Starting with the socket furthest from the PSU feed the cables in and attach to their sockets.
Turn the PC on and make sure it boots up!
If it doesn't you've almost certainly got a loose plug, so go round and make sure they are all bedded in nicely.
Almost certainly there will be a few cables that aren't needed, these can now be tied up out of the way.
Tidy the rest of the cables up, securing to the case out of the way of fans and to leave a good air flow to the bits that matter.

I am OK now on the orientation of the heatsink/fan and the PSU. Thanks for your inquiries and comments.

I have a more urgent problem now. My first build I bought a PSU with all the cable pre-attached to the PSU. The problem with that was I was left with a bunch of wires in the box that went nowhere. So this time I bought a modular PSU where I have to attach to the PSU itself only the cables I need, only the labels on the PSU are confusing as to their meaning.

First off I have one for the 24 pin connector. OK, that one is obvious where it's connected.

Second I have a group of 5 with 8 pins in each one. That group is labeled "6+2 PCIE & 4+4 CPU".

Third I have a group of 5 with 6 pins in each one. That group is labeled "Peripheral & SATA"

Lastly I have something call "CLink" with one odd connector.

Ok, so now I have connected the 24 pin connector to the MB.

Next I know I need to connect an 8 pin ATX12V1 to the MB.

I have 2 cables that have 8 pin connections on each end - they have the label "CPU"

I think I have to connect one of these to that ATX12V1 on the MB and probably to the "6+2 PCIE & 4+4 CPU" group.

This is my first hurdle that I have to clear.

I'll worry later about setting up my SATA drives and PCIE video card.

The main thing I want to accomplish now is to be able to get my power up signal telling me that all is ok.

I know of course that I first have to install the cpu and heatsink/fan but as far as the PSU set up is that all I need to start. That is the 24 pin and 8 pin connection? The 16GB of memory is already set up on the MB too.

I also need to confirm that I am setting up that 8 pin correctly.

Correct.

and probably to the "6+2 PCIE & 4+4 CPU" group.

If you mean that as sockets on the power supply, yes. That "group" would be to supply extra 12 V to the ATX input and directly to PCIE GPUs, etc (some have 6-pin inputs, some have 8-pin).
[Edit] Ah, yes, found a picture on eBuyer. Definitely connect to that group. In fact, you can hardly go wrong -- if it's 8-pin it goes there, if it's 6-pin it goes in the peripheral group. Ignore the CLINK unless you have a second P/S... [/Edit]

I know of course that I first have to install the cpu and heatsink/fan but as far as the PSU set up is that all I need to start. That is the 24 pin and 8 pin connection? The 16GB of memory is already set up on the MB too.

That should be enough to get a bios display, assuming you have an on-board VGA/video output.

Ivan, I think that was one hell of an answer.
Thank you, thank you.

It helps if you give links, I forgot the exact model

Sorry BilBg,
I'll have to remember that.
Here it is, it's an RM850.

Have some info (e.g. what is "Corsair Link" (C-Link))
Have some PDFs and FAQ

There is this (interesting for me) info in CORSAIR-PSU-MANUAL.pdf
"Corsair’s GS, TX, TX-M, RM, HX, AX (not including AX1200) and AXi all feature a Zero RPM fan mode.
At low loads, the intake fan will not spin, allowing the power supply to operate in absolute silence."

Thanks BilBg,
C Link just shows performance of the psu. Speed, temp. etc.
The quietest one -- I like that.
Nice reports. I never even thought to look at the pictures on the box. They were throwaways from the start. Ha.

It seems to me: all the sockets on the power supply that have the same 'shape' are equivalent.
If you can plug a cable in it - it is in the right place ;)

I think there are two "4+4 CPU" cables in case the motherboard have 2 physical CPUs

Indeed. With a single rail PSU you can't mess up which socket group to use.

I know what a cpu_fan is; I know what a cha_fan is, but I don't know what a pwr_fan is. What is it? I don't think I have anything like that.

Some power supplies have a connector so you can monitor the PSU fan via the MB. My older Enermax PSUs have those.

i would skip the pwr_fan as the Corsair Link is used in place of that

That is true. When I did my first build It was recommended that I use a single rail. Yes cable management is harder. (And I stink at it, But my second build is a tad better) But it is safer for the novice builder in opinion. And to tell the truth, I was more afraid of screwing something up on my second build.
