That would be no more than 585W being pulled out of the PSU then. I guess that's why it's so quiet.

You're probably right. The 850w version was on sale when I bought it.

Vega 64 can pull as much as 330W under full load. So, I'm not surprised his system is pulling upwards of 585W out of the PSU.

I just feel it's always important to make sure that when saying a PSU is quiet to also say what it's powering so that it's put into perspective.

It's like with my RM550x: it's always dead silent, but my power consumption never goes above ~350W either.

Hell, my old ass X58 with i7 960 OCed to 4.2Ghz and two ATI 6990s were drawing 1600 watts from a 110v wall monitor I had.....and that was using a AX-1200, lol

All my new stuff doesn't come anywhere near that rigs power consumption....

But on to the PSU fan....I don't think I've ever heard the fan noise on my Seasonic SSR-750PD 750W Platinum.....I hear everything else BUT the PSU fan. Unlsss OP has really quiet PC and it sits right next to you on the desk, maybe it could be an issue I guess......

What will the PSU be powering?

What do you use your computer for?

How many hours per day would you say your system is at peak load where it's pulling hundreds of watts?

Do you overclock? If so, is it casual overclocking just for more performance? Or are you doing extremely competitive overclocking?

Please try to answer all of these questions.

Nah, it's not complicated, but I just checked Corsair RM850i that has stellar reviews when it comes to AC ripple, and my EVGA 1000w PQ is still better

What you actually asked for in your confusing OP is for a linear power supply, I don't know of a single one for the consumer PC market.

Get a decent PSU and then replace your whiny mobo/GPU VRMs. 100% of PCs will whine in some situation, be it 1000Hz mouse moving, 2000fps rendering, high speed networking, high RAM usage, ... anything periodic in audible frequency that puts a strain on some component.
Do you know of such a PSU? Do you know the name?

What kind of UPS do you use, can you link me or name it?

Do you have a commonly reported "churning" of the fan on the Seasonic?

Please use multi quote instead of making a new post as for the RMi its the same as the RMx just with the buggy Corsair Link added so not worth the extra cost

Sorry, but you're obsessing over things that don't matter unless you're doing extremely competitive overclocking. Look at me with my sig rig; I have the Corsair RM550x and I'm extremely happy with it. I didn't have to spend days or weeks trying to decide on it. I just looked at all the PSUs that are safe to buy and I went with the best one at a price I could justify spending and boom, I got a new PSU. Done, and done.

Tell me what you can justify spending and what your PSU will be powering, and I'll give you some options and then you can just choose one and be done with it. I guarantee you I won't recommend any that you'll regret buying.

Edit: Why didn't you answer any of my questions? Sigh. I knew I should have mentioned how much I hate that. I asked those questions in order to give you the help that you came here for.

Edit 2: Since the discussion below is about the noise, I haven't heard any sound coming from my RM550x. As for the claim that it gets hot, well, I'm not worried about it since my power draw is much too low for me to be concerned about the temperature of my PSU (it's definitely not worth getting down on my damn hands and knees to pull of my side panel every day just to touch my PSU in the middle of a gaming session). I estimate that my absolute maximum power draw (like while gaming) is about 350W, and 350W is only 63.64% of the 550W continuous output capacity, and my average power draw is closer to about 100-150W.

Never heard any noise from it....but my PC sits on the floor, PSU is on the bottom and the fan faces the floor and it’s in Hybrid mode....just checked it again with all my fans off...still don’t hear churning noise switching the Hybrid mode on and off.

I'm not really sure how "common" this really is. First your videos are both a different model than the one suggested and second the gold video even calls the unit "ridiculously quiet" with the db supporting this. I do admit the fan startup in the first vid could be an issue.

Since everyone loves anecdotes the Seasonic gold x-750, platinum snow 750XP2, and platinum 860XP2 I've owned were all quiet as a mouse and I've always run them in fan on rather than hybrid. Granted I likely only put a 50-60% load on them outside of synthetics.
