Answer continued from below page: How to assemble everything - cables and connections

Steps Since you already put the processor and heat sink on the motherboard, instruction is not necessary. But before you install the mobo, use the below manual to install the RAM. Pages 38-41.Install the motherboard. You will need a manual. The manual tells how to install it and plug the on/off and status LEDs on the case into the mobo (mobo is short for motherboard). Manual: Pages 30-32 http://downloadmirror.intel.com/16958/en...Install the power supply unit, or PSU for short. Use the manual included with the case or the PSU’s manual. A good cheap PSU: https://www.amazon.com/EVGA-WHITE-Power-...Install the HDD. Again, use the case manual.If you do get a GPU (referred to as GPU, graphics adapter, graphics processing unit, etc.) use page 44 of the mob manual to do so.Now start plugging stuff in. This stuff doesn’t need to be in a special order. Using a SATA cable, attach the HDD to the mobo. Page 45. (for future reference, all page numbers are for the motherboard manual unless otherwise noted).Plug in the all the header pins with the help of the case manual and mobo manual pages 46-50. This can be annoying.Plug your main two fan into the motherboard. If you have any extras, plug them into the PSU using a molex to fan header adapter. Page 51.Plug the 2x10 pin motherboard connecter from the PSU into the mobo. It will be marked “motherboard” on it. Page 52.Plug the CPU power connector into the mobo. Also page 52.Plug the SATA power cable from the PSU into the HDD. SATA power has 5 multi colored wires that terminate with a thin inch wide connector. If your GPU has a power connector on it, plug it in. Use the GPU’s manual. Well, that about covers it. If I missed something, nothing could be critical to the system. If you plan on putting Windows on it, simply use the Windows Media creation tool to create a bootable USB drive to install Windows from. Done plenty of times, very simple.

@pccheese - thanks for your answer on the PSU connectors. I have a question on the below chart so I am posting my question here. I have only been able to do the B, G and F connection from below chart and have no clue about others. Can you advise if the other connections are required as well? You will be my GURU for my modern PC built, if I dare to do so, and you don’t mind :)
