I have bought an led strip from ikea which takes 12 volts. I want to power it with my power supply from an old pc (rated 480 watts). I know that the voltage is the same, but should I worry that the amperage is too high and might still end up burning my leds?
Well I would like to know two things before I attempted to wire the ikea strip to a power supply. Is the 12 volt requirement AC or DC voltage, you didn't state which. I would also want to know what the current requirement of the light strip is. Without that information one is just playing russian roulette.
