@Ekosenko , welcome to the Community.
Here is the Motherboard Specifications page for the computer: https://support.hp.com/us-en/product/hp-pavilion-desktop-pc-590-p0000a/19390500/document/c05991291
Look at the section titled "Processor upgrade information" for a list of the compatible processors. The fastest that is available is the i7-9700F. All of these processors have been fully tested to assure that they are compatible with the motherboard. Any other processor will most likely not work; especially the i9 series.
