4 claimed protections, atx standard requires a minimum of 3 specifics, so barely makes the cut, but is a decent start.
2x12v rails at 24A per rail isn't totally bad for a 600w unit, but their claim of 576w (12v x 24A x2) is pure *** as split rails aren't added on a 1 to 1 basis. That 48A will be closer to 43-44A output, making the 12v circuit closer to 510-530w, not the advertised 576w. That kind of wattage is more synonymous with the older group regulated power supply designs, not the more modern DC-DC.
Only 2x 6+2pin on a 600w claimed psu is another dead giveaway of lack of faith in the unit. As is a 3 year warranty.
Which can mean the protective circuitry can be a wash, some of that built into/assumed by the nature of group regulation.
I'm betting it was a really cheap unit, that gets your attention by its clean looks and rgb fan. Where is the amperage/wattage per rail label? Not even shown on the website, but plenty of pictures of all the pretty wires.
Decent went downhill in a hurry, it's a total snow job, cover up, trick.
Get your money back. A pile of poo covered in bling is still a pile of poo.
