To test power consumption today we are using a Keithley Integra unit and we measure power consumption from the VGA card inputs, not the system wide drain. We measure results while gaming in Crysis Warhead and the synthetic stress test Furmark and record both results.

The power drain of the card is around 245 watts when gaming.

Fallout 4: Anniversary Edition announced for all systems (including Switch 2)
Just under 10 years ago, Fallout 4 officially released to the world. While the game is far from perfect, it resonated with millions thanks to its sandbox-like design and focus on exploration among other ancillary additions (such as the settlement mechanic and base building). As they have done with many of their previous games, Bethesda has now officially announced Fallout 4: Anniversary Edition – bundling the base game alongside its DLC and hundreds of user-created mods.

This is awesome- i love the GPU reviews here. Wish I had £500 spare, or £600 for the 8GB version.
Sapphire focus a lot on the VRM’s – which many AMD partners DON”T. Glad to see you pointing it out in this review
The Sapphire 290 is the better value card, its only 6 phase, not 10, but it overclocks well and saves you £130. enough to get a good new power supply
I prefer their blue finish, to the orange. its very sexy. I still have a Sapphire AIW card, thats how well they are built 😉
Not much of an AMD fan but that card looks sexy.
