For a cheaper PSU you can try a DPS800 and a breakout board. Not sure how much they are nowadays but I got mine about half a year ago for $35 and they're built like a tank + quiet. Their peak power is 800 watts 120 and 220+ is 1000 watts, and they are also 80+ rated IIRC.
Really don't need a break out board just solder the connections to the PSU. Here Is a link how to do it.
