CyberPower PR750LCDRT1U Smart App Sinewave UPS System, 750VA/600W, 7 Outlets, AVR, 1U Rack/Tower

What is the depth?

Is this ups silent or not? the reviews say both, to the extreme. i want this for a rack in a tv area and need it to be near silent when on utility

Will this run on generator power?

Is it 17in wide? And 9in deep?
