From the leaked photos of teh PCB board and specs, it looks like the AMD Radeon RX 6000 series maybe a power-hungry hog. Just make sure your PSU can cope … we recommend a minimum a PSU of 750W to be on the safe side.
Taken from WCCFTech … An alleged PCB of AMD’s upcoming Radeon RX 6000 “Big Navi” graphics card has leaked out which confirms some recent reports that we have heard. The picture was leaked by Twitter user, EB-18, & shows what seems to be an engineering board featuring the RDNA 2 powered Big Navi GPU.
AMD Radeon RX 6000 “Big Navi GPU” Graphics Card PCB Leaks Out – Dual 8-Pin Connectors, 16 Power Phases, VirtualLink USB Type-C Port & 256-bit Bus Interface.
Compared to the previously leaked engineering board, the latest Radeon RX 6000 series graphics card PCB gives us a better view of what to expect from AMD’s Big Navi “Navi 21” class products. It will still be based on an engineering board so the final design could be vastly different than what we are looking at here.
