So first, you have a 1000W PSU for a 386W build, you could go with something smaller (and therefore cheaper)
Second, you have sound card, is that necessary? Because unless you want to do high quality audio or something a realtek adapter on Motherboard is often ok. If you are not sure, check this out: (
