Question which PSU cable goes where on the MB please
Hello. Sorry about the newb post, but I'm completely newbie at modular PSUs and having trouble installing mine
I bought this PSU:
be quiet! Straight Power 11 Platinum 750W
Amazon.co.uk
MANUAL
:

My PSU is the one on the right in the picture on page 1 of the manual
And this MB:
Asus TUF GAMING Z790
Amazon.co.uk
1.
Problem
: main power cable
1.1. it's straighforward where it plugs in the MB at one end
1.2. the other end in the PSU is a
problem
: it's separated into a 20 pin entry, and a 8 pin entry. The PSU has the 20 pin entry, and right underneath another 8 pin entry, both marked as "MB". Since this design is pretty counterintuitive,
I don't know whether I should also connect the 8 pin entry underneath, or leave it unplugged
. Manual is useless on both pieces of hardware on this matter. This video shows something similar, but refers to 24 pins, while I got 28:

, so I still don't know for sure
2.
Problem
: secondary (CPU?) power cable. MB must take 2 x 8 pin connectors according to manual
2.1. Got 2 cables in the kit:
2.1.a. cable with 10 pins (middle ones missing actually) which connects to the only 10 pin slot in PSU.
I guess that's it?
2.1.a.1 the other end same cable separates into a 1 x 8 pin connector named P8, and another 2x4 pin separated but bundled closeby, and named CPU1 - P4, CPU2 - P8. The only PSU slot also is named P8/P4.
I have no idea which of the 2 motherboard 8 pin connector takes which end from these.
The motherboard manual doesn't show these. These cable connectors also have clamps for the motherboard, which don't correspond to anything I can see on the motherboard slot, although I can push them in I think if I try

2.1.b. cable with 10 pins at one end as the other, but only 2x4pins ending at the other, so I guess this is not it since the motherboard manuals sais I must connect 2 of 8 pins each. Again, CPU1 - P4, CPU2 - P8 is written on the 2x4 pins
3. The rest are 2 x VGA cables of 12 pins to 2x8 pins, which I guess connect to the GPU, and storage device and such which seem pretty straightforward, and have straighforward slots for them in the PSU
Display images of cables, but it's unclear what you're looking for. (upload to imgur.com and post link) Did you check the PSU user manual prior to this?
Yes, I mentioned that the manuals are not very helpful (you can verify this).
The cable pictures appear on page 35 of the PSU manual, though my explanation is clearer—there isn’t a 24-pin cable, there’s a 20+8 pin cable, plus one 20-pin PSU slot and another 8-pin slot below.

My PSU matches the one shown on the left in page 1 of the manual.
Nah, I won't wait any longer, but this looks good. I’m not sure how to apply it yet. I just read that an 8-pin connection is sufficient, even when using 5Ghz OC, but I still think a 2x8 pin setup offers better stability. This PSU supports backward compatibility with my motherboard, which is impressive for its time.
Your explanations are quite complex and difficult to follow. Offering photos of your cables would help clarify things. Anyway, let's try to grasp what you're explaining.
Make sure to provide images when uncertain about connecting certain cables. Connecting modular PSU cables incorrectly may damage or destroy the equipment. Please be very careful.
Yes, I'm confirming I'm not going to cause any issues by entering it incorrectly.
Taking pictures with the phone, uploading links, and editing are a lot of work.
Photos won't assist unless you can picture what you're doing. The 20 + 8 connector seems similar to the 20 + 4 connector—10 pins in one row versus another, then 4 pins over 4 pins or 2 over 2.
The main question is whether I should connect the separate 8-pin or 4-pin bundle.
I sent an email to both Asus and be quiet! support (their site is down, which is encouraging). I'll wait 12 hours before plugging anything in, but I'm gaining confidence. Why isn't this simple...
I hope not working would be the sole option, since that would simply be a straightforward solution. But if I mess anything up, it's already fixed.
