Looks like my seasonic one died. Someone told me that 650W is barely enough with everything overclocked. I want a good one (even though seasonic is supposed to be good). thanks
Get a Corsair RMx 650 Watt PSU.
And it has a killer price for the moment.
You will not find any better 650 Watt PSU at that price range, very quiet and with 10 years warranty.
I agree with mark5916 -- best deal/quality PSU today is the Corsair RMx 650 (2018)--hard to beat the $86 price tag.
On your (dead) Seasonic FOCUS Plus Gold 650, have you contacted Seasonic to RMA? I would think that it is still be under warranty (they have a 10 year warranty).
Some other quality PSUs are the EVGA G3 650 and BitFenix Whisper M 750 ... both of which cost around $106 right now.
And to answer your question about "how big" of a PSU you need, a quality 650W PSU will provide enough power for your i7-8700K/GTX 1080Ti rig with overclocking.
Note, the EVGA G5 650 is also available for a great price, but I'm waiting to see how the reviews/testing goes with them first, since they are new. (the G5 replaces the G3)
Lastly, with a high end build (i7-8700k and GTX 1080Ti), I would not recommend the EVGA 650 GQ to get a PSU with only a 5 year warranty--especially for $115 bucks. There are better quality options available for less $$$.
I bought this one, seems like plenty of overhead juice and reliable.
Whoever told you that was a idiot. The GQ is a downgrade from the Focus.... Cancel it. Instead of buying a new PSU RMA the Focus.
I never RMA"d a PSU, don't I have to send it in while my computer sits there? Or will they send a working unit in first and I can send back the old one?
