The wattage rating label for the PSU, as you can see on the specifications page, up to 1000W of the 1100W that this PSU can supply can be drawn from the 12v rails. That is a seriously beefy amount of 12v power. The UL number indicates that this PSU has been made by Cooler Master, which means it hasn’t been outsourced to another company and just had Cooler Master stickers thrown on it.
