Anyone recommend a really quite PSU

[ShadowKnight]

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 whatsoever

I have two PCs running Enermax PSUs, one is an Enermax Infiniti 650W - 3 years old now I guess. It is modular, has a very quiet, slow spinning large fan; excellent PSU. Also has a nice feature whereby the PSU keeps the system fans spinning for a while when the PC is shutdown if the temp is over a certain value.

My Enermax Revolution 85+ randomly resets my PC every few couple of weeks or so, something which never happened when using the Seasonic X-series that it replaced (which will be returning soon). This is something it had in common with my previous Enermax from 6 or 7 year back.

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.
A couple of percent difference always depends on viewpoint and use. The more you are running the system, the bigger the cost of that couple of percent difference in real life.
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

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

[Pancake]

How did you work that out? whats the specs? the online calculators are useless really

[Trash Man]

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?

I would definitely recommend Antec Truepower (seasonic underneath) (modular) off eBuyer, I've had it since ever and it's still going strong.
