I am using my 580 Watt Tagan at the moment, and have never had any issues with it, however it does produce a lot more noise than I would like. I used a Hiper before and this was almost silent under normal conditions, but well it was a hiper so it went wrong.
I used an Enermax Galaxy 850W for a while which is a fantasic PSU, but is definately not a quiet one and covered over my top exhaust when I would normally fit a fan.
So now I'm looking for a modular PSU which is almost silent but has the power on the 12V rails to happily run my 8800GTX and the rest of my system. Been looking around the 700W range, but the GTX needs atleast 29A on a rail I believe. Not worried at all about LED spent the last year getting rid of any fans with them.

I've been looking at the following:
Silverstone SST-OP750
Seasonic M12-700
And briefly at Coolermaster Real Power M700 and the Tagan ixeye 800W

I've got around £100 to spend, but would prefer to keep it below that if possible as looking for a new CPU cooler as this artic freezer 7 is producing too much noise too. (Though i've read they are meant to be quiet so there might be something wrong there.) Nothing is overclocked and if I ever do get my 680i board back from EVGA I might get around to it, but noise is more important than overclocking at the moment. Looking at thermalright 120 Ultra - good idea?

So any suggestions on the PSU's and tell me if I'm looking at totally the wrong ones, up till the last 2 yrs I'll always gone for the cheap and cheerful PSUs.
And any suggestions as to the cooling for my cpu aswell would be great.
Thanks
 
Corsair 520W Modular PSU (£68.14) will easily run a GTX / quad system with no trouble at all, even with an overclock. Don't be put off by it's wattage :) If you are a bit "nngh" about it, then get the 620w version but it's £30 more. Either the 520w or 620w PSU is VERY silent, and regarded as two of the best power supplies around.

You could get the 520w version, and still have enough left to most likely get a Tuniq Tower 120, which is also a superb cooler.
 
I would recommend the Corsair 620HX. It has plenty of power and i cannot hear the fan on mine at all. Build quality is excellent, and its modular too. They have demonstrated these running SLI with no problems. It certainly ticks all your boxes.
If you get the Thermalright 120 Ultra you will also need a fan. I use the Tuniq Tower on my E6600. And as you can see, its at 3.4ghz overclocked on air.
 
Thanks guys, I have looked at the Tuniq more than once before, but what I have read is that it creates a fair bit of noise compared to others? Fans aren't an issue though with the thermalright. O that was the one I really was interested in - I used to have a Zalman CNPS7500-CU on my FX55 and the whole thing was silent, it was amazing, so I was wondering how the 9000 series compared and whether they are any good compared to the tuniq and ninja's?
Has anyone else got any suggestions for PSU's as would like to hear if anyone has any other suggestions rather than buying it now and finding out tomorrow that there is a better one.

Another I looked quickly at was the ASUS silentknight, i thought this was more of a novelty one so didnt read up about it much, but seen some people say its great, anyone know?

I love my Tagan, and unlike some PSU's that claim to be silent, it really IS! There is not a whisper from it. In fact I had to put a bit of paper into the fan blades to confirm they were turning :D

Although I have read on here a lot of guys recommending not to use Tagan, so I don't know. I guess it's like any piece of hardware - there will always be good and bad stories to tell.

If you do decide on Tagan, make sure you get one with the TSCT - TAGAN SILENCE CONTROL TECHNOLOGY. Those are the ones that are super silent.

As for your ACF7Pro, if you can, adjust the settings on your board to not allow it to get to 100%. Up to 80-90% is great, that last 10-20% is damn noisy.

I've got a Tagan 580 running in here at the moment and I do love it, but this one is the TG580-U22 and is little too much noise for me.

Just noticed that the Tuniq needs a backplate, are these easy to change as I will be getting my EVGA 680i back soon and don't want to be ripping brackets off and struggling to get them to stick again...

what about the Zalman noiseless PSU 600W, sure its not silent, but anyone know anything?

I can only think there is maybe something wrong with your Tagan, because I cannot hear mine. The only difference I can see in the noise specs is yours maxes at 30db, whereas mine is 28db, as are some of the newer (U-25) units.
 
The tuniq fan is noisy on full. I ran mine on minimum and couldnt hear it. I think the Thermalright needs a backplate too. You get them all with it. Though its better to not stick the backplate on the motherboard with the supplied stickypad as its a bugger to get off if you need to.
 
Don't buy Tagan, there are better power supplies out there for the money.

The OP750 is only quiet if you get a certain revision, I have Rev1 which made a ticking noise then I had a Rev 2.5 which again still made a bit of noise.

The Seasonic has a 60mm fan but it's quiet until it kicks in as it's thermostatically controlled. Should only come on during high load when playing a game, and surely silence doesn't matter then.

If we had a Poll I suggest the Corsair would come out well on top - it’s already well recommended on this thread.
Someone might come forward with their personal favourite but it won't change the consensus.
You'd need a lot of recommendations for an alternative which still won't get the level of support that the Corsair gets on this Forum - from my experience.

You won't get a definitive answer - just opinions

I can’t recall anyone saying their Corsair is noisy although there will inevitably be some negative anecdotal comment about them.

I’m after a quiet PC but I wouldn’t compromise the choice of PSU by going for a PSU which is notionally quieter than the Corsair when the Corsair is so well regarded and is widely acknowledged as being quiet.

I suspect you’re going to need an incredibly quiet PC for the noise they generate to be any sort of issue. The Corsair is the PSU on my shopping list

I have the same as you and have had it for two years and sitting 1m away from it, it is very noisy and I have thought about buying a new one.

Would it be worth upgrading to the corsair 620 ?

I pressume sitting at only 1m away you would still hear some noise from it and this is what is putting me off ??
 
Thanks Marse, but the reason I asked this is that there is a chance that the 2 first responces we either one copying the other or both just sharing their favourates and wanted a few more opinions to make sure that this was definately the case.
Thanks for the help with the PSU guys I will probably be ordering a corsair 620W tomorrow.
Any more ideas on the cpu cooler as the tuniq is hard to come by atm and was wondering if it is definately better than the thermalright 120 and any of the zalmans??
 
I notice the tagan when I'm doing other things in the room really. I often sit on my bed and use my computer from there, and can hear the drone of the fans over music - about 4 meters away. just annoying really, esp as my setup with my fx55 was so quiet.
 
What about the TT Big Typhoon VX? Fully adjustable fan speed so you can set it how you like it, and in all the reviews I have seen, it's right up there with the best on offer.

Yeah, i'm getting sick of the noise after two years.In your case if you usually sit at 4mtrs away you should find a difference with the corsair though ?

I'm hesitant to spend £90 because in my case at sitting only 1mtr away I don't know if it is worth it or not.

Remember and post back your review please, because I would be really interested to hear how you compare the noise with modern psu to a two year old psu.
