Be Quiet! Dark Power Pro 12 - 1500 Watt PSU Review - Product Showcase

And check that out, 4x40A and 2x45 Amps on the six 12V rails. If it was still a thing, then this PSU could take four GeForce RTX 2080 Ti graphics cards, and then still have 500 Watts left for the rest of the PC. A high-end graphics card consumes roughly 15~20 Amps per card at best, the math here is easy (multiply with 12 volts).

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 specifications. 
• 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 Series 12 DPP  power supplies have a modular sleeved 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 more than enough connectors for this PSU model, have a look at the supplied connectors, all with decent length by the way. The benefits of this dark sleeve design are a cleaner, neater look. The cables are also long enough to support full-tower cases.

You'll also spot small plastic combs, with this you can tie and manage the sleeved cables, as that can get quite messy.

And last but not least, the OC Key. You can activate one big 12 Volts rail if you prefer that, you can simply use the jumper wire to enable it, or if you like a little more flexibility, you can use the included PCI Slot switch.
