Seasonic PRIME 650w PSU. Just read a few reviews on this PSU. It may be a bit pricey at $160 but it comes with a 12 year warranty, longest warranty I've seen to date. Fully modular and 80Plus Titanium rating, there really isn't anything else on the market to match it. 650 watts is more than enough to power your system. Linus had an OC'd 7700k and SLI OC'd 1080's running on a system and they were pulling less than 500 watts from the wall. Tech is only going to get more efficient. Never skimp on your power supply, this is the heart of your PC and buying a shitty PSU to use money elsewhere is a horrible mistake in the long run. Check this out if you are in the need of a new power supply. www.amazon.com/Seasonic-Titanium-ATX12V-Supply-SSR-650TD/dp/B01HXYRJYK/ref=sr_1_1?s=electronics&ie=UTF8&qid=1492912692&sr=1-1&keywords=Seasonic+650W+80+PLUS+Titanium If you are unfamiliar with Seasonic, here's some quick notes. Seasonic and Flextronics are the main PSU power supply manufacturers. Most companies buy their PSU's and slap their name on it. Examples would be PSU's like the Corsair AX860 which is made by Seasonic and the Coarsair AX860i which Flextronics makes. Seasonic also had fantastic customer support if a problem should arise and their warranties are unmatched in teh industry.
