Cooler Master Real Power Pro 650W PSU

At first glance, we can see that a total of 191 Watts are provided on the +3.3v and +5v rails, 540W on the +12v rail, 9.6W on the negative rails, and 17.5W on the +5v rail (for USB) giving us 650W total. The Real Power Pro is rated for a maximum of 780W but under normal circumstances (that's equipped in a PC that will max it out) it runs at 650W continuous. The Real Power Pro also has triple +12v rails (peaks of 19A across the board). Additional rails will aid in keeping a system stable as you can separate devices based on power consumption into the rails of your choosing
