A long as you trust the company it came from, you should be fine. Some cheap PSU's falsely advertise the 12v rail so just google your model of PSU and if it's reputable 500w should be enough (as long as it has the right connectors too.) Google PSU calculator for an exact wattage for your setup, I'm guessing around 300-400w at full load with the 1080 depending on how many USB devices you have plugged in.
