Hey guys, I'm buying an ASUS Radeon RX 570 Expedition OC 4GB graphics card on sale, I was wondering what psu I could use for this graphics card because I'm about to build a new pc. would i need 80+ silver or gold? what do i get?

Official AMD site recommends 450 W power supply. When choosing power supplies you should always get one with at lest 80+ Bronze efficiency. Popular and reliable ones like Seasonic, EVGA, Corsair. ASUS Radeon RX 570 Expedition OC 4GB needs 1x8 pin PCIe power connector so be sure to choose PSU with PCIe power connector.

The 80+ scale (80+ / Bronze / Gold / Silver / Gold / Platinum / Titanium) is really just a scale of efficiency, or perhaps quality. Sometimes the prices are the deciding factor. Suggest you visit a few PSU calc sites and get a feel for the overall system power draw.

I prefer to get a PSU with 1.5x the calculated amounts to ensure 50%-70% load. It's not a must, but it's not a bad idea, as it allows for additions later if necessary, and in the case of PSUs with a fanless mode, it helps keep the fan noise down.

e.g. 329W x 1.5 = 493.5. So a 500W (66%) or 550W (60%) PSU.

I personally prefer minimum of Bronze rating, whatever the system. I would settle on the general wattage first, make sure you know all the different power connections you're going to need, then go from there. Higher power capacities tend to be Gold and above anyway, while lower wattage models with higher colour ratings are less common.

I recommend Corsair or Seasonic PSUs. Also, consider semi-modular or full modular if you can afford it. It makes for an easier build, and less clutter can help with airflow.
