CPU from 'platinum micro' OK? Also M2 SSD question

About to pull the trigger on a gaming build for the wife who doesn't need a high end system. Choosing an I5-12600KF and Platinum Micro has the best price on the CPU, but are they legit? Will I get a boxed CPU or a CPU in an ESD blister pack meant for a manufacturing line where they get bulk CPUs?

Also planning on getting a Patriot P400 lite 1TB PCIE M2 drive. Okay or hold out for a more name brand offering?

Thanks
