The M12II EVO will be a solid choice. Very good psu, all japanese capacitors, also comes with 5 years of warranty. Your pc will draw close to 300 watt or so. So it also gives you headroom for overclocking and future proofing. Also fuly modular!!! You said M12II, seasonic now manufactures new edition called the M12II evo. Anyway original M12II also uses all japanese capacitors.
Go with it.

Or you can check if you can find the Antec High Current Gamer series for the less money. They are internally same as M12II evo.
Only difference is the fan and antec uses a panasonic capacitor as primary. Everything else is similar.
