new power supply makes ping sound

[jim dude]

how come my new xfx 750w pro series makes a ping sound when it starts up and when I turn it off??? just installed it today and it makes a type of meal popping sound on start up and power down??? should I send it back and ask for a new one???

I think some electronics do that (my amp for example). Please don't double post if you don't get an immediate answer: http://www.tomshardware.co.uk/answers/id-2105451/ramdom-sound.html
