I'm planning on buying this desktop. https://www.costco.com/HP-Performance-Pavilion-580-Desktop---Intel-Core-i7---4GB-Graphics.product.10.... It has the 4GB AMD Radeon RX 550 Graphics. I have read that it requires 350W minimum PSU. The HP desktop only has 180W. Is there a problem with the power supply? It seems that the HP desktop should be more. Thanks in advance for any input.

Hi,

Apparently HP is using an OEM low wattage version of the AMD RX 550.  There are at least 30 different makes and models of the AMD RX 550 excluding the OEM model used by HP.

Hi,

Once you get your PC, run GPU-Z and do the render test. This should give you some information about the power draw.

HWiNiNFO64 will also give you the GPU power draw.
