Now that the PC is fully unboxed, replace the side panel/s and any other panels you removed in order to remove inner padding/packaging. Ensure everything is in good condition, and then feel free to move the PC near its final home. It’s time to find all the original cables and accessories, which again may be included within the inner case box OR could be located inside the motherboard box/related accessories box/bag. Your wifi antennae, power supply internal cables, and other various accessories will be located in one of those locations. Consider storing unneeded spare parts in the motherboard box for safekeeping.
Plug in your power cable to the wall or a surge protector. We highly recommend a UPS (uninterruptible power supply) to fully protect your system. Suggested models will be made by Tripp Lite or APC (at least in the United States).
The power cable then plugs logically into the power supply. You can then flip the switch from “O” to “I” for “on”. If you notice a secondary switch or button here, don’t sweat it, this is the “hybrid mode” button, it will allow the PSU to turn its internal fan off if it senses low power draw. This further reduces your energy costs and makes the PSU last longer. During high power draw, the fan will always spin if needed, so operationally you should feel free to do whatever you want with this button, it won’t affect you in any meaningful way. Next, plug in your monitor cable/s to the GRAPHICS CARD ONLY. This is critical, as some machines may present a set of ports on the motherboard by the USB area in the back, which are functional but do not involve the GPU at all, completely bypassing it.
This will make using the computer for anything other than basic web browsing a horrible chore and completely waste its potential - so be sure to plug monitor cables into the GPU ONLY. AMD machines often lack these confusing motherboard display outputs, or will not render a signal at all if plugged in, making the mistake much more obvious.
Plug into the GPU’s i/o as shown below. HDMI and Displayport are the modern standards, as Phynix Pc will never ship a card old enough to have other ports. Both of these standards are adequate for even very high end monitors.
Remember that the Displayport has a LATCHING connector, so you should not yank these out of either device to which they are connected. The HDMI has no such latch and can be more conventionally removed.
You will want to attach your ethernet cable or wifi antenna during this step as well. The wifi antenna will be screwed into the screw ports on the back of the motherboard or a separate card below. USB devices are self-explanatory. Modern wireless peripherals often play poorly with USB 3.0 ports, but your mileage may vary. Both blue and sometimes red superspeed USB 3.0 ports can also be used and MAY work with any and all devices attached to them, so try switching ports if any issues arise with something you are trying to use. USB 3.1+ Type C ports are also available on many models of motherboard and provide a huge speed boost for type C devices.
