LED lighting - larger power supply?

I calculated I need roughly a 24 watt power supply to run my lights. Can I have a larger power supply, and how large is too large? I found a 50 watt, 3 amp supply for a good price. I have always heard that of going 20% over your calculated wattage.

You can never have a power supply that puts out too much current. With these new type switching supplies, the power supply only uses the amount of current it needs to run your load.

Not exactly sure what your power supply is because 50 watts is just over 4 amps and a 3 amp supply would be 36 watts.

A 50 watt power supply would be a good choice for your application.

That's what I thought as well. I guess I was just unsure whether a 50 watt (4A) power supply would be too much when I only needed 24 watts (2A). Thanks!
