I'm considering replacing my Intel Arc A380 with an Arc B580 and possibly upgrading my power supply, but I need to keep costs under control. My current system has a Ryzen 5 5600G, Arc A380 6GB, 16GB of DDR4 memory, a 512GB SSD, a Gigabyte A520M DS3H AC motherboard, and a 550W GAMDIAS AURA GP550 PSU. Would the B580 work well with this setup, or should I upgrade another component first?

The B580 should work, but your A520 motherboard and Ryzen 5 5600G run PCIe 3.0. Since the B580 uses an x8 interface, it would operate at PCIe 3.0 x8, which can reduce performance somewhat compared with a newer platform. Make sure Resizable BAR is enabled in the BIOS, along with Above 4G Decoding, because Intel Arc cards lose performance without it. The 5600G may also limit the card in some 1080p games, but you should still see a substantial improvement over the A380.
Keeping the 5600G and putting the budget toward the graphics card makes sense. The B580 is a strong new-card option, but the included power supply is the part I’d be cautious about. A quality 550W unit may technically be enough, but replacing the GAMDIAS unit with a reputable 600–650W model would give you better reliability and headroom. Upgrading to 32GB of RAM later would also help newer games, but it is less urgent than the GPU and PSU.
If you’re open to buying used, an RX 6700 XT is another option worth checking. It has 12GB of VRAM and a full x16 PCIe connection, so it is less affected by the PCIe 3.0 limitation. Its drivers are also mature. Just compare local prices and make sure the used card is in good condition.
There isn’t one specific 6700 XT model you must buy. Sapphire, XFX, PowerColor, and ASUS versions are generally worth considering; focus on price, cooler condition, and whether the card has been heavily used for mining.
So it should still work reasonably well, even though it won’t perform exactly like the benchmark results from a newer system?
