I'm upgrading from a Sapphire Radeon 7770 Ghz to a Sapphire Radeon RX 480 Nitro.
The PC wont even get to BIOS when i start.
PC is a HP Pavillion p7-1058uk with this mobo
PSU is 500w
BIOS is up to date
Previous drivers uninstalled with DDU
Most likely the stock HP power supply and motherboard are unable to fulfill the power requirements of the RX 480.
It's not a stock PSU but I've heard the one I have is not up to it. It's an atrix brand.
Yea that's worse than garbage. Look at a Corsair 550w-750w, 550w will be sufficient but the price difference between the capacities is often small (sometimes higher wattages are cheaper), and buying twice the PSU you need ensures longevity and highest efficiency.
