According to the spec datasheet that board only supports CPUs with a TDP up to 87 Watts. The Core i5 7xx and Core i7 8xx are all 95 Watt TDP CPUs, so even if the board did boot with them you may encounter throttling under heavy workloads due to the board's weak power delivery not being able to keep up.
You can give one of those higher TDP CPUs a shot if you want, but you're probably going to want to use a downdraft cooler or add extra fans to provide additional airflow over the VRMs surrounding the CPU socket. You can also forget about overclocking.
In any case, all of the available CPUs are going to be 10 years old and aren't great performers these days for the most part. Depending on what you plan to do with this PC, you may be...
