PurePower 480APD Butterfly (W0020, 480W)

This is yet another power supply whose actual manufacturer is Sirtec. It is newer than the one described in the previous section but belongs to the version 1.3 standard, too, with all the ensuing consequences.

This PSU resembles the previous model externally, except that the fan on the top has moved to a side panel and the input voltage switch is now missing. The W0020 features an active PFC device with the full range of input voltages, so it just doesn’t need that switch.

A big letter X with the Xaser brand logo in the middle is fastened to the side panel of the PSU with four screws. If you take it off, you’ll see this plastic window:

Of course, they don’t make windows in power supplies for no reason. There is a LED behind it. The LED has three colors and is blinking at work.

You can see in this snapshot that the LED is shining in green and red at the same time. A number of blinking algorithms is written into the LED and they replace each other automatically. Another such LED is fastened on the case of the fan in the PSU’s top panel:

As you see, this is not a highlighted fan proper, but a fan with a separate LED.

This is a multi-colored LED, too (its red light is shining right into the camera in the snapshot above and there is also a green reflection on one side). It is blinking with all its colors following a few algorithms that change automatically.
