In Figure 20, you can see the power supply label containing all the power specs.
Figure 20: Power supply label
This power supply is advertised as having four +12 V rails, which is correct, since the monitoring integrated circuit has four +12 V over current protection (OCP) channels. Click here to understand more about this subject. Optionally, you can configure this power supply to use a single +12 V rail by installing the switch shown in Figure 4.
The four +12 V rails are distributed as follows:
- +12V1: The main motherboard cable and the peripheral and SATA connectors
- +12V2: The first and second video card connector
- +12V3: The third and fourth video card connector
- +12V4: The ATX12V/EPS12V connector
This distribution is perfect. However, when using two connectors for video cards on the power supply (i.e., when you install four video cards, since each connector has two cables), don’t install them side-by-side, or they will be connected to the same rail; skip one connector (i.e., use the first and the third connectors) to make each video card use a separate rail. Of course, if you configure the power supply to use a single-rail configuration, what we are saying won’t matter.
How much power can this unit really deliver? Let’s find out.
