What sound are you looking for?

No that card wont work, it will cook its self in an M720q.

What you want is a https://www.ebay.com/sch/i.html?amp%3B_trksid=p3814320.m570.l1313&amp%3B_nkw=MCX312B-XCCT&amp%3B_sacat=0 MCX312B which runs much cooler and can comfortably fit in an M720q.

the default 65w PSU is fine with an i3/i5, but you can get a larger one if you want. I can try testing idle power though I am on a 110v/60hz system so it may not be exactly the same.

I have seen line speeds at nearly full bandwidth on mine in synthetic testing.

I ended up adding a M.2 A+E 2.5gb network card in place of the wifi card which gives me 4 network interfaces. stock intel 1gb, M.2 Realtec 2.5gb, and 2x Melanox 10gb SFP’s.

Last thing, DO NOT USE RJ45 SFPs. The draw way to much power and generate lots of heat. Use direct attach cables, or fiber to connect to switches/routers.
