In Figure 16, you can see the power supply label containing all the power specs.

Figure 16: Power supply label.

As you can see this power supply has six +12 V rails, which are distributed like this:

• +12V1: Main motherboard cable, video card auxiliary power cable that has two connectors on it, peripheral power cable with just one connector on it.
• +12V2: ATX12V and EPS12V cables.
• +12V3: One of the SATA power cables, one of the peripheral power cables.
• +12V4: Two of the SATA power cables, one of the peripheral power cables.
• +12V5: Two video card power cables labeled as “B” (yellow sticker), see Figure 3.
• +12V6: Two video card power cables labeled as “A” (green sticker), see Figure 3.

With six rails this power supply could have a better distribution. Since SATA and peripheral power cables nowadays do not demand a lot of power, they could be grouped together, allowing video card power cables to be on separated rails.

Now let’s see if this power supply can really deliver 1,100 W.
