PSU Advice.

Hello,

 

I’ve been in search for a new PSU for a while now and I finally narrowed it down to these. To those that know power supplies, which out of these would best go with the system in signature?

 

Fractal Design Ion+ 860P

Cooler Master V850 850W

Corsair HX850i 850W

Corsair AX860 860W

EVGA SuperNOVA 850 P2

Corsair AX850

Or something better suited from NewEgg Canada or Amazon?

Look at Seasonic

You don't really need 850W for your system, 650W would be plenty. 

I'd suggest Corsair's RMx or be quiet's Straight Power 11, as they're much more reasonably priced than the PSUs you put in your post and are still very high quality.

If I had to pick one out of the ones you mentioned though I'd probably go with the HXi for the digital monitoring and it's about as high-end as you're going to get/need.

These links don't work, if they're relatively the same price then HXi, it's multi-rail and one of the top PSUs performance wise overall, other ones aren't too far behind but they're all single-rail. But, as were already said, you may not need 850W depending on what you'll be using this PSU with, like the one in your signature, it would be fine with good 650W PSU, even 550W if it's just for gaming. But in this case, why you're replacing AX1200 then ? Sure, it's old and out of warranty but it's very solid unit, no reason replace it if you don't have some problems with it

Thanks for the suggestion. I’ll make sure to look at what 650w my local shop has in stock. This is a reading of how much watts this PC takes straight from the wall while running Witcher 3.
 

I forgot to mention one thing, is it possible to have a zero rpm mode on a 650w-850w? Just because this PC will be in my bedroom silence would be appreciated.

This unit started making this really loud high pitched noise. Very annoying.

Absolutely, look at the PSU tier list, units marked with blue color can be considered quiet at up to ~70% load. And keep in mind that the power consumption numbers you see here are after what are dissipated in the PSU itself, i.e if this were measured with AX1200 Gold, with roughly 90% efficiency, 550W on the outlet would be about 500W load on the PSU itself, weird number, this exact CPU + GPU build clocked just about 400W in TW3, but you seem to have a shitton of fans in it, maybe they contribute that much, but that aside, you will be okay with 650W unit (assuming it's of 'quiet' sort, like Corsair RMx), especially considering that if you're sleeping, it presumably wouldn't be loaded at all so it'll be quiet anyway.
