Hey i am getting a r9 270x soon and was wondering what PSU i would need as i think i currently have a 500w supply as it has a big 500 on the side of it.

More about : psu graphics card

It depends a lot more on smaller things like the strength (amperage available) of the 12v rail. However a 500w PSU should be fine for a single GPU system as long as you don't have an excessive number of drives or something.

r9 270x uses 142 W in bitmining (99-100% load), your other system components usually use ~200 W more, which means your 500W PSU should be enough for it.

But the problem is, you didn't tell us your PSU manufacturer! If it's a generic 500W PSU I wouldn't recommend you using it.
500-550W PSU models from Corsair / Antec / SeaSonic are quality and will bring you great performance and reliability for years of usage.

You don't need to buy another psu as your current 500 watt psu is enough for r9 270x.
