Your adapter is providing 25% more amps than required by the device.
It seems a bit risky to me.
So just to clarify, my gf bought me a nixie clock for Christmas, the seller said 100% not to use a DC plug adapter which is rated above 200mA. If I buy one which is rated at 500mA, it won't do anything to the nixie clock?
what watt?
I know appliances will only draw the wattage that they need on the fly. Didn't know how it worked with amps. The internet can have daft advice at times. Figured I'd ask here before potentially melting a switch![]()
Isn't the correct amperage value important for the fuse? ie. if there's a fault with the device or a power surge the fuse breaks to protect the equipment?
Amperage? Oh my.
The amp is the unit used when measuring current. Yes, if the current drawn by the circuit is greater than the fuse can handle then it will get too hot and snap. It is there in case something in the circuit shorts to prevent damage/injury.

Oh electronics genius, does my 620W PSU draw 620W all the time?


Yeah you can, with a pen.


Lost me there... You quoted your 620w psu drawing 620w, it doesn't ... It can consume 620w of power. Drawing amps gives no indication of power unless you factor in volts. (Hence watts)
This is just like people in motors quoting torque, when bhp (wih rpm In the equation) should be the real headliner. Of course with electricity it's all a lot more important...get it wrong and things go wrong
