If you want to upgrade your GPU to a high-end, then you should also upgrade your power supply to at least decent quality.

Yeahh but the 1080 was a gift, it's an ASUS Turbo GTX 1080 8GB
If you run that power supply with your GTX 1080, you're likely to not have that gift much longer.
That PSU is garbage even as garbage PSUs go.
See that +12V rail with the 17A? That means that calling this heap of junk a 550W power supply is the equivalent of calling me a supermodel if I wear a Speedo up under my beer belly. What you have there is a 204W power supply, even if the parts were the highest quality you've ever seen. Which they aren't at that price and configuration.
A 1080 at load can hit 180W by itself. You were already running your PC on the edge of danger. You start running that GPU on that power supply and then it becomes a multiple choice game:
1. Overpower protection kicks in, shutting off the power supply
2. Some combination of the CPU, GPU, RAM, and motherboard are destroyed.
3. The whole thing catches on fire
Given the lack of protections on junk-tier power supplies, option 2 and 3 are far more likely than you'd want.
