Robert M has it correct, a back 500 will not handle a G5. You can get much stronger APC units of RS-1000 or RS-1500 va capacity for reasonable prices on sale. They have true AVR, eight outlets and USB connection for connection to computer. I replaced two of my three older and smaller models when the batteries crapped out. I paid about $160 each some eight months ago to replace mine for the RS1000 models, but have seen occasional sales at Frys's & CompUSA on both the 1000 & 1500va models for less. The G5's suck a lot of amps so I would probably go for the 1500va model to give yourself some expandability for future needs.
