Hello everyone,

I'm planning to build a pc because I want to replace my mac laptop with a windows desktop for gaming and school purposes because my mac is getting problems with the battery and I can't game on it.

When I searched for the required amount of Watts using Newegg's calculator it came up with a required PSU Wattage of around 900 W, but Sapphire recommends a PSU of around 500 W for the card.

I'm not planning to crossfire/overclock the build.

So how many Watts does this build need and are there any things that I need to change for the build?

Thanks in advance.
