ADATA BN-550 Power Supply Review

Power Distribution

In Figure 15, you can see the power supply label containing all the power specs.

Figure 16: Power supply label

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). Click here to understand more about this subject.

The two +12 V rails are distributed like this:

• +12V1 (solid yellow wire): Main motherboard cable, one of the ATX12V connectors, one of the video card power cables, and the SATA and peripheral power connectors
• +12V2 (yellow/blue wire): The other ATX12V connector and the other video card power cable

This distribution is adequate.

How much power can this unit really deliver? Let’s find out.
