So Cooler Master – MasterWatt 650W had some noisy coil whine when under load and I replaced it with Corsair – RMx 650W 80+ Gold Certified Fully-Modular ATX Power Supply. Happy with it. Almost no coil whine when loaded, dead silent on normal use. And it is rated better and has very positive reviews and price/value ratio, so would recommend it. As a bonus it has bag for cables and PSU itself (I don`t imagine where one would use the latter as it is not a thing that you carry around, but anyway… ).
