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?Quote:

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?Quote:

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?Quote:

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. :rolleyes:Quote:

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.Quote:

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.Quote:

Well, I run a i7 920 setup with a 600 Watt Seasonic and its not noisy and is enough, my next one will be around 700 Watts Be Quiet! to accommodate for the GPU beasty that will be available at the time. I have good experience with Seasonic and Enermax, though my Enermax supply is now used since 11 years now and I don't have much experience with their current range.
Overspeccing on PSU will just end up running it inefficiently or simply sinking money in capacity you do not use.
Some manufacturers give out the rough power supply for their specs, you can use that as a guideline and estimate how much watts you need counting the efficiency of the PSU, then add some legroom for expansion and general buffer. Plus, keep in mind that some systems have a high initial start draw, the even out :)
Tbh, a couple of percentage is not going to make a difference to anything whatsoeverQuote:

Either Enermax are rated well above their quality, or their quality control is pretty shocking, as I'm currently giving them a 100% unsatisfactory rating from the past half a decade. Needless to say, I think all all the Seasonics I've ever bought are still ploughing happily on, many of which have been running pretty much 24/7 for years. I'm thinking I'll stick with them in the future.
Well, with overspeccing I am referring to use a 1000 watt PSU where a 500 or 600 would do and offer enough reserves. Other than efficiency of the PSU, the purchase price of the higher rated PSU is also something to consider.Quote:

I work with server systems as well, thus me trying to optimize down to percents :) But of course everyone has to decide for themselves if they want to care about the difference in cost.
I just got
OCZ ZS750W-UK ZX Series ATX PSU - 750W from pcworld its the quitest PSU I have ever had. Ok its 750 but I think OCZ do a 1000w in the range
Mike
I just workd out my new build is going to use roughly 822 watts so my hx750 wont cut it. Looks like a 1000watt will be needed for me. Im looking at the ocz zx 1000 watt gold one as it has good reviews (johnyguru)and is resonably priced
How did you work that out? whats the specs? the online calculators are useless really
Just stuck a BeQuiet 680W E9 in my new build and it's near silent.
Very impressed over all with how quiet my PC is. surprised with how little noise the MSI Twin Frozr II's put out.
Surely an 850W will be more than enough?Quote:
