160W/5V is 32 Amps!!!
If your power supply can supply the power you should be OK. You'll probably need multiple-parallel connections to the power supply (or supplies) with heavy-gauge wires because the resistance of the wires & connections will result in a voltage drop (good 'ol Ohm's Law). For example, if you run a long-string of LED strips, the LEDs at the far-end will usually be dimmer.
