And check that out, 2x20A and 2x24 Amps on the four +12V rails allowing 750W of power draw for graphics alone. This 750W PSU could power two GeForce GTX 1080 cards or Radeon Rx Vega cards. Considering a high-end graphics card eats roughly 15 Amps per card and 20 at best, the math here is simple.

Overview of all voltage rails for all six models

All of the power supplies in this Series have the necessary protection functions, even in extreme conditions. Below is a list of the included protections:

• OCP: Over Current Protection. This function will latch the power supply off if any given rail is overloaded beyond a safe level. 
• OVP: Over Voltage Protection. This function will latch the power supply off if voltages exceed specification. 
• UVP: Under Voltage Protection. This function will latch the power supply off if voltages drop below specification. 
• SCP: Short Circuit Protection. This function will latch the power supply off in the event of a short. 
• OTP: Over Temperature Protection. In the event that temperatures exceed a specified value, the power supply will latch off. 
• OPP: Over Power Protection. If the total output power of the power supply exceeds a safe level, the power supply will latch off.

The power supplies have a modular cable set that allows you to use only the cables you need for your particular set of components. When it comes to wiring we feel that there are enough connectors for the 750W PSU model we tested. Have a look at the supplied connectors, all with decent length by the way. The benefits of this dark design are a cleaner, neater look. The cables are also long enough to support full-tower cases.

The ATX motherboard connector cable is almost 60cm, the Molex and SATA power cables up-to even 100cm, the 4/8-pin CPU ATX power connector cable is at a great length of roughly 70 cm and the PCIe graphics connectors reach up-to 60 cm as well. 

You will receive multiple sets of PCI-Express graphics power connectors, obviously wiring is different per PSU model, in the chart below you can check that out.

beQuiet! uses less internal wires as a selling point: wire-free design on the DC side. No wires result in better cooling because no cables can obstruct the airflow. Better cooling increases longevity. The connections between components are also shorter, which means fewer signal disturbances. No induction from cables also increases signal quality.
