Hi I have a Seasonic GX-650 fully modular PSU. I have having trouble finding what cables go where. MOBO is MSI Tomahawk MAX. 
there were also two different packets with cables and I was wondering what those were. 
I am very lost.

Thankfully, you can't really plug things into the wrong place. Every connector is keyed on the PSU side and the component side.

 

So... hard to mess things up.

 

You need the big 24 pin for the mobo itself, then the CPU will use a 4+4 pin. GPU will be some combination of 6 or 8 pin connectors (you should have got a bunch of these in the pack, thats how you can determine those are for the GPU vs the CPU, there will only be one for the CPU, well, possibly two but I doubt it on a 650 watt). Then you have SATA power for ssd or hhd, and thats really it :)

Thank you for the reply. If I have just a m.2 SSD do I still need a cable for it?

Nope. No cables needed for a m.2.

Ahh okay. So what I will need is the 24pin, the CPU cable, and one of the PCIE cable for the GPU?

Yup. 24 pin is the huge guy, its on the right side middle ish of every mobo. CPU power is top left. And the GPU is pretty obviously on the GPU lol.

 

Just don't force anything if it doesn't go in easily, its the wrong plug. Sometimes it can be tricky to get the little click tab to engage, but that doesn't mean its the wrong cable. If its the wrong plug, it won't start at all.
