Parts are:

  • Sapphire AMD Radeon RX 480 8GB GDDR5 PCIe 256bit
  • Corsair VS650 PSU


How old is the PSU? Swap another "capable' one in it's place to test that you haven't extracted all the value from the Value Series PSU. Preferably one that has a single large 12v rail to feed that 480.

So, you can or can not enter the BIOS ?


To better help you please list out ALL the components that comprise your system by Make and P/N's.

Trying to install a Radeon RX480 and when I do, the machine won't reach the POST stage. Without, it boots just fine. 

Have updated the BIOS to the most recent version. Tried with internal graphics card disable or enabled, same result. Have tried two Radeon cards with exactly the same result. Have also tried different PCIe slots, same result.

Any ideas?
