What PSU?

Currently I have an old PC, with a 650w BeQuiet. Upgraded graphics card recently, and I had to underclock it because PSU kept failing. Am unsure if this is because it's old (~5y) or because of more power being drawn.

I'm looking at eventually upgrading to a skylake system. In the interim, I'll replace my PSU so I don't need to underclock my graphcis anymore.

What's a good PSU that will allow me to upgrade around it? And am I right in saying going for overkill (850w/1000w) will be quieter and more efficient?

Thanks!

Thanks for replies, bit nervous about 650w because that's what I currently have, and I suspect the current system is failing because 650w is not enough!

Phenom II power consumption peak 338w
Radeon R9 200 peak ~300w

I want something future proof, so multi cards might be an option for the future. Would you still recommend another 650w supply?

Was honestly looking at something like this:

It's overkill but will be future proof, has a good warranty. (And I'm assuming spare power = better efficiency and quieter)

I'm just trying to avoid needing to buy another one for 5+ years, this is why my old one's been so great. At the time it was overkill and I've saved money because of it in the long run!

Just trying to avoid buying another 650w one and running into problems with it later. I think I'll probably go for 1000w/1,200w unless someone tells me strongly otherwise.

This one is what I'm close to ordering, good reviews and says it's very quiet:

Thanks for tips, went for EVGA SuperNova P2 1000W '80 Plus Platinum'. 10y warranty sounds great.

Perhaps it's massively more than I need but it's a solved problem for the next 5-10 years now!
