I'll straight up say what USAFret is saying a little more subtly - BOTH those power supplies will most likely blow up in your face. Okay, that's an exaggeration, but they are a VERY serious risk to use in ANY system. If you are trying to actually set fire to your PC and its neighboring objects, then they are excellent choices, otherwise listen to USAFret and buy a proper power supply that isn't a fire hazard.
