will this one handle 4x r9 290 or 4x r9 390? https://www.ebay.com/i/122841705413?rt=nc [/quote] It's not the best PSU you could find. Go for Delta DPS-1200 (any modification that has only +12V output is good). PicoPSU - 180/250 W Breakout - at least with 3 oz copper, look for it to have beefy connectors I won't advise any cables, many of them are crap, especially the cheap ones.
