I want to get a XFX - AMD Radeon RX 580 GTS Black Edition 8GB GDDR5 PCI Express 3.0 Graphics Card - Black

But the computer I have has a max combined wattage of 680w
Is that enough?
This is my power supply

Yeah you'll be fine

No

That PSU is junk. It only has 22A on the 12v rail (12v X 22A = 264w), I would expect more from a good quality 300w psu. It’s the 12v rail that is important.

I just updated the question because I chose a different card. So not sure if those answers still apply

Update the PSU?

You need a new psu. Your psu I wouldn’t even use in a basic office pc let alone a pc with a dedicated gaming gpu.

Absolutely not.

Your PSU is rated for 264w on the 12V rail, at most. This measurement could’ve been made at ‘peak’ or lower operating temperatures. It may only be able to deliver 200w in your conditions.
This arises a couple issues.
Firstly, this is undoubtedly undersized for an RX 580 System. The RX 580 can use 250w, alone, while gaming.
Also, this is an indication of a crappy PSU. It may only last a year, and take out components with it.

So, definitely buy another PSU.

For a recommendation, please provide full system specifications so we can ensure compatibility, which retailers you prefer to purchase from, budget, and any special requirements/desires such as quietness, efficiency (if electricity is expensive), modularity, etc.
