In Figure 15, you can see the power supply label containing all the power specs.
As you can see, this power supply is sold as having two +12 V rails, which is correct, since this unit has two +12 V over current protection circuits (see previous page), and we could clearly see two “shunts” (current sensors). See Figure 16. Click here to understand more about this subject.
The two +12 V rails are distributed as follows:
- +12V1: All cables but the EPS12V/ATX12V
- +12V2: The EPS12V/ATX12V cable
This is the typical distribution used by power supplies with two +12 V virtual rails.
How much power can this unit really deliver? Let’s find out.
