Au contraire , the blower type RX 480 is a conservative choice in term of safety installed in these machines , Alex .
All of the RX 480 blower type cards I have installed in cMPs that look like the picture , whether made by Dell or Radeon branded , stay within the power safety ranges even when at full System load . Specifically , the PCIe slot will not need to provide more than 65 W and the single mini six pin PCIe booster on the logic board will not need to provide more than the 75 W it is safely rated for .
I watch this like a hawk , Alex , with all my builds .
I admit , it's unusual for a graphics card to pull more than 30 or so Watts from the PCIe slot , but the slot is safely rated for 75 W .
And there are a lot of advantages to using this card over the officially recommended RX 580 .
Here are some pictures of the sensor read outs during a System stress test with one of these RX 480s installed in a recent Build :

The PCIe air channel fan is set to a constant 1200 RPM because this is an AMD card and no unusually high temps were noticed with an infrared temperature gun in the PCIe slot areas . The blower fan on the card acts an an exhaust fan in this channel , since there is no system exhaust fan here installed at the factory . That actually helps to keep temps reduced in the PCIe slot area , over alternatives ( like open air type fans on GPUs , like found on the official RX 580 ) .
