Installing a PSU

venomx · 29 Dec 2020 at 15:40

Never done it before, any tips ?
Will be getting the RM750x

Seems fairly straightforward...
1x CPU 8Pin
1x PCIe - 8Pin
1x Motherboard - 24Pin
2x Satas for one HDD and one SSD

Is it best to fit the PSU first and then route and connect the cables ?

I don't need to take the mobo out mate, I just need to install the PSU

Ok nice one. I have some velcro cable ties too.

Excellent. My case has a good back panel where the current PSU cables are routed and it's very tidy. Hopefully i'll make it clutter free. Seems as though routing the cables tidily is the most time consuming part.

Thanks.
Two sides to each cable. For example, the side which says "CPU" in white goes into the CPU, and the other end into the PSU ?

Yes... one goes into the motherboard and the other in one of the PSU connectors labelled as 6+2 PCIe & 4+4 CPU.

Ya but does it matter which side you plug in ? One side says CPU and the other says " Type 4 "

According to YouTube, the " Type 4 " side goes into the PSU

Only thing is, the PCIe and CPU both look similar on the PSU side, ( obviously different on the other side where they plug into the GPU and CPU power )
If I plug in one at a time should be ok

Aparrently it doesn't matter where you put the 4+4 or 6+2 cable ( into the PSU ), providing it's an 8 pin socket

So bottom right, it doesnt matter which one has the CPU and which one has the GPU.

No, it does not matter.

Nice one thanks !

Checked the cabling out before installation. Some of the connectors are missing one pin on the side which plugs into the PSU, is this normal ?

These are molexs for the front fans right? They are rgb

Ya it's the pcie one in the first pic...
The cpu one has no pins missing, the molex does have one missing and the SATA has two missing

As far as I remember , the 3 pins never plugged into anything, only the molexs were connected to psu

woohoo. installed it.
Thats the GPU, CPU, Heatsink, Ram and PSU i've installed myself so far. ( Was a custom built pc from another place )

One slight problem. I did connect the wrong end of the CPU cable into the mobo, and I only realised when I tried to fit the other side into the PSU and it didn't go. Luckily everything seems fine

I also didn't expect to have to use any molex cables. It threw me when I saw them, however i connected them all up fine
