So I built my first pc about 3 weeks ago, I got a 600w PSU and that was more than enough, but I didn't have a hard drive yet, just a 970 nvme m.2 500gb ssd. But because I needed more storage space I ordered a Seagate Barracuda 2TB 3,5 HDD, and after installing it I realized that my pc wouldn't boot anymore. After a few days of doing research I noticed the hard drive makes a beeping noise every time I turn on my pc, I looked up what it means and the answer i got was that it means it doesn't get enough power. But after running a power/watt calculator test thingy on all of my components , monitor, keyboard, mouse, etc. combined it said I needed at least 544w of power, which means I should have more than enough watt in the PSU I have now as its 600w...anyone know what the problem is here?
