The last time i built a pc for gaming was 5 years ago. Basically a new Xbox One... BUT NOW I AM STEPPING MY **** UP. I already have my gpu, cpu, mobo, ram, storage, fan and, case sorted out but now i need a Network card to hook up to wifi and a PSU. -I need the wifi card to be $25 or less and i need it to be external (preferably USB 3.0). -I also need a solid PSU, one that has warranty and is 650w-750w. I am not asking for 80+ Gold or anything but at least 80+ Bronze. The PSU needs to be under $90. Which may be a challenge but i trust you gentlemen to assist me. Thank you all in advance
