Question New Computer Build - Not Working

[MaxArk]

Interesting. The manual's only reference to it is within the list of "special features". It does not share any information as to what it's used for, how to use, or even how to connect it. I have no extra cables to interface it. I'm looking online for more info, but I'm only reading that it's an optional feature with not much support for it.

Those ports should be for CPU. My z690 has those for cpu power and they look exactly that way. On my corsair rmx850 power supply I had to hook up 2 8 pin connectors labeled CPU. So you should have cables labeled that or something similar that should attach to the power supply.

They are labelled on the motherboard as ATX_12V_1 and ATX_12V_2 respectively. In the manual, they are simply referred to as power connectors, and grouped into the same explanation of their use as the ATX_PWR connector. Doesn't specify when to use or the other or both, just that they are available. Absolutely no reference to ProCool lol.

I did find cables to connect them to my PSU and I'm willing to give it a try. Do I use theses in addition to the large ATX_PWR cable? Both ATX_12V_1 and _2, or just 1? The biggest problem, I really doubt I'll be able to make any connection due to space. See the attached space. The blue circle shows where those MB connectors are. Cables are not going to get through that little opening.



Will need a taller case.

They are tight. You can run them inside the case if you have to. You’ll notice the gpu usually has a notch cut out where they can run up the channel. But the pro tip is that if possible, you usually want to run those behind the motherboard tray before you mount the motherboard and leave them hanging out so you don’t have to finagle with them later.

If you want them behind you may be able to loosen the board just enough to poke the connectors through one at a time. Part of yours though is that you’ve got the aio there. Which is normal just less space. But if you have to, run the cables up the left side under the gpu, when you install the card there should be a small notch they can sit under usually, then run them up near the io shield and plug in.

I managed to connect two 8 pin cables provided with the PSU to the 2 ATX_12V connectors and pass them out that tight spot. Not as graceful a run as what you had suggested. The cables weren't long enough to go around from the front to the back and to the front again, so I had to leaf them through a tight opening near the edge of the MB. A little too close to exposed pins for my liking. No love for this case. The amount of bulk from the pwer cables has resulted in me having to remove the SATA drive bays. Not sure where I'm going to put a drive now.

Anyway, one of the two cables has been successfully connected to the PSU, however, both cables are NOT the same. Although an 8 pin connector that fits in the PSU next to the other, the retaining clip is too big! It's double wide where all theothers are just single clips. There is no where on the PSU to connect this!!!

If this doesn't kill this project, I'll be surprised. The amount of work it takes to do any work in the case, with the huge 3 fan cooler and rad, is crazy. I have to take the top off the case and lift it off with the radiator and fans to get access to the headers and connectors along the top edge of the board. And it's not very cooperative.

Such a subtle difference you don't care to look. It connected to the motherboard with it's single clip connector. I assumed, like the other, that the ends were the same.



Do I need both??

 

[ohio_buckeye]

On my Intel system I connected both. I’ll leave it to someone more familiar with as m5. But I’m assuming you’d want both having a higher end cpu. You might try to look that board up on YouTube and see if anyone goes over it in detail.

As far as where to install drives, my board has 4 nvme slots if I recall. So you might just go all nvme.

Thank you Steve B. This is all getting very unsatisfying lol. So, to be clear, mu power switch wire has writing on it. "Power SW". This should installed such that the words are facing "down" ... meaning facing the outside of the cabinet (the edge of the mother board) ? Or facing into the cabinet, (facing into the mother board). Luckily I don't have a reset or HDD light wire.

As far as the display, I was hoping I would be able to use the onboard display to help diagnose which component might be causing the problem ... one at a time. If I have to rely on the GPU, how do I know it's not causing the issue? If I plug the GPU in again when I get home, and it doesn't post up, tHen I'm back to post 1 with still no idea what's going on.

I have to head into town today, a two hour drive, not something I want to do everyday. Happy if anyone has any suggestions on whether I should try to exchange anything, and if so, where to start. Since my RAM wasn't on the vendor's list, I thought I'd start with a known compatible product.

when you look into your case and the mother board is virticle. all the writing on the front panel wores should face down(towards bottonm of case/floor) only "reset switch" writing should face up towards top of case.. ..

Do I need both??

make sure they are both "CPU" cables and not "8 pin PCI-E cables. "

 

[MaxArk]

Why has this turned so complicated lol? Both cables have CPU written on the two unconnected ends as per the attached image. What is on the other end will require me to take everything apart again to look just to check. But, both cables are not the same in that one end has a single retaining clip and easily attaches to the PSU, but the second has a double wide retainer clip, and cannot clip into the PSU.

I started to wonder through the night disrupted my slumber whether or not my PSU is appropriate to host the CPU cables as I hadn't recalled seeing "CPU" markings for ports on the back of the PSU. It's very hard to see inside the case to the back of the PSU with all the cable to see the print. I went online to check out the Thermaltake ToughPower GF3 1000W PSU to ease my mind. The image shows two independent banks of 2 each 8 pin "CPU/PCI-E" connectors. But neither have a double clip to accept that unique connector.

Thoughts? Is this intentional? Or a fluke? They are the only two cables marked CPU, although feel free to visit the link. They have pictures of the cables that came with the PSU. If it's a fluke, can I just by a CPU power cable? I would think though this cable was shipped to ensure it only gets used one way, and maybe that way is not the way I'm trying to use it.

OK friends, I've made a lot of progress. Exchanged the RAM and connected the two CPU power connectors and I can now post up! The power button works (ON/OFF), however, the front fans aren't spinning. I've got the colour (connected a 3 pin female to a 3 pin male that was attached to the cooler cable). I can get the fans to spin, but I don't have enough empty fan headers to to power all three. There is still this mystery connector, picture in post #5 that terminates a series of three interconnected wires. (Photo below). The wires all go to the front of the case, possibly the answer to the three fans? Maybe the unknow connector is the three fans shared power? But where does it go?



The unknown connector is at the bottom. At the left edge of the picture is a male RGB connector. From the bottom up, I suspect the three cross wires are the fan power. The top wire goes to a button at the top of the case which is supposed to provide modes/colours for the fan lights. Perhaps the whole cluster is just for the lighting, but nowhere to my knowledge to to plug in a male RGB cable. The RGB headers on the board are male. Where I currently have the lighting plugged in, the case has a female connector that plugs into the female connector on the cooler's controller cable, so it's not as simple as swapping the two.
