These 12V 5A adapters are small (~2x4x1in) external adaptors, they failed on my several times. They are not design with cooling system and yes they do run warm especially when run 24/7. I even had standard case power supply fail on me twice, so yes I try to buy them with extra watts capacity and most importantly I always ask for one with Japanese capacitors. -- Thelma
