Do make sure the CPU and RAM with the same specs are listed on the QVL for the motherboard.
I don't see an OS. New computers need new licenses. The only exception is full retail licenses can legally be transferred, as long as previous installations are removed. So, if you bought an OEM/System Builders license (by far, the most common) for your old system, you cannot legally transfer it to this new one. And that includes W10 if you upgraded to W10 based on the old qualifying OEM license.
That K version CPU does not come with an OEM cooler.
I don't see a PSU. I recommend using the
eXtreme Power Supply Calculator to determine your minimum and recommended power supply unit (PSU) requirements. Plan ahead and plug in all the hardware you think you might have in 2 or 3 years. This might include extra hard drives, a bigger or 2nd video card, more RAM, etc. I recommend setting Computer Utilization to 16 hours per day and CPU Utilization to 100%. These steps adjust for capacitor aging and ensure the supply has adequate head room for stress free (and perhaps quieter) operation. These steps also add a little buffer for unplanned future upgrades or added hardware demands.
Note that all power supply calculators tend to pad their results to avoid ever recommending an underpowered supply. It is always okay to buy too big a PSU (except maybe for the budget) but always bad to buy too small. But the eXtreme PSU calculator is, by far, the most conservative (a good thing) when it comes to padding results, and that is due, in part, because it has the most flexibility.
