Yep, black is common DC ground for all the voltages. The -12V and -5V are negative in respect to DC ground, they're typically low power outputs. On many supplies, there is no -5V, that's an optional output. For instance, my supply has no -5V, the -12V is a 1A maximum current output as well. The +5SB is the standby power, it's available even when the supply is off unless the main power is also off. That powered the startup circuits on the motherboards for the soft power-up.
