Is a 600W Power Supply Enough for an ARC B580 GPU?

You can use online calculators to estimate your total power draw. I've had a PSU that was too weak before, and it would just shut down during demanding games. Just be cautious because with the right configuration, you'll be fine, especially since the B580 isn't very power-hungry.

With the B580, you'll likely have no issues since it runs under 200W. The 5500's TDP is low too, at 65W, so you should manage with 600W in most cases.

It also really depends on what else you have in your build. If everything else is pretty efficient, like if you have a Ryzen 5 5500, you might be okay. What PSU do you have again?

The PSU recommendations are typically based on high-end systems. If you're not running a super power-hungry CPU, like a top-tier i9 model, you should be fine with 600W. Plus, Intel suggests a 600W PSU for their reference B580 model, so you might be in the clear!

Yes, you could have problems. The 600W might not be enough in stressful scenarios.

I recommend putting your entire build into pcpartpicker.com to get an estimated wattage. That way, you can get a clearer picture of whether your PSU is adequate or not. Don't forget to share the parts list link here!

Manufacturer PSU recommendations are usually rough estimates since they don't account for your entire setup. To be safe, check your power consumption when the system is under load, add the GPU's TDP, and leave a 20-25% safety margin. If you can't measure it, check online for your CPU's peak power consumption, add another 70-100W for other components, then see how that holds up against your 600W.
