maximus XI code questions for first build!

[Bayonett Priest]

before i never build a pc so please bear with me!

i am still waiting for my 9900k to arive but i have a few questions about the motherboard

1. in the cpu powerconnectors are 1x8pin and 1 4pin connectors! do i have to get a specific psu or does the rm850x from corsair suffice?cablewise!?

psu: https://www.alternate.co.uk/html/product/1480111

2. i plan to use 3 corsair ll120s and a aio witch i think need usb connections! i looked at the maual of the motherboard and there stands:

4x usb2.0 port

1x ASmedia usb 3.1 gen 1 controller (can you explain me what that is too?)

2x usb 2.0 headers support 4x usb 2.0

and on the motherboard there is a 9pin connection witch says node! wha tis that?

3. on the xi code there is no screwhole in the middle should i screw off the standoff?

1. You will have enough cables for both the 8 pin and the 4 pin. Both plugs will use what's called a 4+4 power cable. It's two separate 4 pins on the same wire that can be stuck together to make an 8-pin. These should be labeled "CPU" and are for the CPU supplemental power connectors only (obviously)

2a. Your AIO should just plug directly into any USB 2.0 header no problem.

2b. There should be a section in your motherboard manual about this (and all your other questions should be in the manual of the respective part anyways)

3. The middle stand off is not directly in the middle, it is offset to the right a little bit. Also I see that your MoBo has a shield. Just look on the back of the motherboard to confirm the hole is there. Your case should include one stand off that has a point on the end instead of a screw hole. This is meant for the middle stand-off as a tool to align your motherboard in the case when installing it. Again, that should be in either the case manual.
