What PSU would be best for my VR computer I am building?

[alexander.garcia2722]

I do not know what PSU would be best for the PC that I am building.

I plan to get a GTX 1070 ti and an Oculus Rift, but here are the parts I have.

Current Parts:
i5-8400 6 core
16 GB DDR4
Gigabyte Intel Z370
-----------
What power supply would be the best? Like brand and wattage.

For GTX 1070 Ti, any Seasonic unit in 600W range would be more than enough, e.g: G-650, Focus+ 650 (80+ Gold), PRIME 650 (80+ Platinum) or PRIME 650 (80+ Titanium),

You'll get 5 years of OEM warranty with G series PSU, 10 years of OEM warranty with Focus+ series PSU and 12 years of OEM warranty with PRIME series PSUs.

Also, PRIME 650 80+ Titanium is the best 650W PSU money can buy at current date and with it, you'll get the highest efficiency (94%), tightest voltage regulation (0.5%), longest hold-up time (30ms), lowest ripple noise (20mV) and longest warranty (12 years) there is. Fully modular cables and toggle-able Premium Hybrid fan control too.

All my 3 PCs: Skylake, Haswell and AMD are also powered by Seasonic while i have the PRIME 650 80+ Titanium unit in Skylake build. Full specs with pics in my sig.

Oh, all fully-modular Seasonic PSUs are also compatible with CableMod SE-series custom sleeved power cables.
To match my Skylake's black & red theme and Haswell's black & blue theme, i have replaced the stock black power cables with CableMod SE-series custom sleeved power cables,

Though, if you plan to go with mini-ITX build, look towards Seasonic Focus SGX650 SFX PSU since it's much smaller than standard ATX PSU,

Or when your build theme is white, you can go with Seasonic PRIME SnowSilent 650W PSU as well,
