    -Careful with that ax, Eugene...

    Depending on the power rating of your particular ATX PSU,
    those seemingly safe 3.3, 5 and 12 volt rails can crank out some serious current.
    Guess the PSU sticker tells you the max power that each and all rails could deliver, and/ or check link below.
    Fuses aren't merely a powerful stimulant for the Upper Classes,
    thus a 1 amp fuse would be pertinent (at least) to your AUX USB.

    For instance: Hooking your aux USB power socket to a worn-out & shorted cell phone charger cable,
    would draw some +18 Amps (100W - more than your soldering iron) before the internal current-limiting even kicks in.

    I've even used one of these PSUs for a heavy-duty styrofoam cut- & rip saw:
    Instant Heavy Duty Styrofoam cut- and rip-saws

    Links: ATX 12V Power Supply Output Rating

    -Have fun but stay safe!

    Cheers
