Anyone recommend a really quite PSU

[Qazteck]

Hey can anyone recommend me a PSU around 1000w that is really quite/silent?

Thanks for your time

Corsair/Enermax or BeQuite! is the brands to go with

Pfft. You want the best.

Seasonic Platinum-1000. Will set you back around £220.

£220 seems a bit much anything cheaper but still the same quality?

Will keep them brands in mind

Do you really need 1000w? What are you trying to run off it? A lower rated PSU will often be quieter as the unit will have less heat to dissipate (provided the manufacturer is a good one to start with)

[ik9000]

Most manufacturer's give noise charts on their website for dB noise vs % load. While it's difficult to compare between manufacturers (test environments might be different) if the stated noise dB ramps from 20dBA to 39dbA at 50% load (the range at which you want to start thinking about using the power supply in) then chances are it won't be the quiet experience you're after. NZXT Hale90 range are very good noise vs power wise. They sit at 20dBA (according to their measurements) across the board. Sadly they are rather hard to come by at the moment.

Huh? you do know that a 1000W PSU doesnt knock out 1000W all the time right?

Sure, but is there any point paying the extra for a 1000W supply if he only needs a 600W supply? Also, running a PSU outside of the 50-70% load bracket is often less efficient and costs more in electricity bills over the unit's lifetime. Buying too high-powered a PSU and running it at 10%idle, 40%flat out could end up costing the user more money upfront and again in bills. It will depend on the system and type of PSU, but the really good 1000W PSUs with good efficiency across the board will cost over £200. A good modular 650W will set you back circa £100. Ie leaving you enough to get a 120GB SSD. Which would you rather have?

The pricing doesn't really matter to me and i know that running it may cost more but it will provide some future proofing and it will be quieter and that's what matters

[jim]

You do realise that you're future proofing yourself for quad-SLI or something insane?

PCs don't use anything like that much power, even heavily overclocked gaming machines with dual-SLI don't get close.

If you're into spending more money than you need I'm open to financial contributions.

An 80plus gold (Recommend Corsair AX850 and Seasonic X series) will be quiet and efficient especially when operating at 20-30% their rated power - often in this situation the fan will be off or inaudible.

Powering a reasonable system (say an AMD A6) using a decent 1000W PSU will use more power than a similarly decent PSU rated at 400W. It's just the way it works. A PSU isn't equally efficient throughout the range.

I think most will agree that Seasonic are the best brand (they make most of decent Corsair PSUs) and indeed do a couple of fanless PSUs in the 400-500W range. Some of their other PSUs will shut down the fan if the system isn't demanding all the power.

Yes the seasonic X series are all semi-fanless AFAIK, when demand and temperature are below a certain level the fan switches off. (All except the fanless models)

But yes I do agree with many here, unless you've got a specific build now then a 1000w psu is pointless, ie you're planning on making a quad gpu system now, we do tend to overspec our psu's anyway.
I don't think there's any current single graphics card setup now that could not still be powered by the old corsair HX520w, that's already nearly 6 years old yet still capable and I'm not sure there's a dual gpu setup that would over stress the HX620w

As long as the world is filled with over-rated PSUs though, they're here to stay. If every graphics card box is going to advise you to buy a 600W PSU, that's actually a 400W PSU with the four crossed out and a 6 written next to it, then people will keep buying the 1000 models.

And it also means that every time someone starts a build thread I have something to suggest
