Good Day People, Having hit a wall at the moment with my build having had to return two power supplies due to first faulty and the second horrible coil whine. I've come to ask for advice on a silent and quality PSU. However I have some constraints it must work to at least 850 watts, fully modular and, have a depth of preferably 160mm due to my ft03 case. Any advice would be much appreciated, Many thanks Magnetobob
The Seasonic X-850 is 850W, fully modular, and has a depth of 160mm. Its fan first spins up at heavy loads and shouldn't have any coil whine issues. The 750W model has been reviewed here: http://www.bit-tech.net/hardware/psus/2013/04/26/best-power-supply-psu-720-750w/8
Here is another one reviewed on this very website http://www.bit-tech.net/hardware/psus/2008/11/13/lian-li-silent-force-850w-psu/1
Also check out PSU that only turn of the Fan when needed. My Crossair 850(AX?) has this feature and rarely ever turns on the fan in a µATX build!
Thanks MSHunter the corsair 860 was something i took at look (similar I guess to your 850) and was a a viable options it just seemed many people had experience with coil whine. I admit for many people it probably doesn't bother them but after going down the line of keeping everything quite the buzz would likely be extremely irritating. Deders this would have been the perfect solution I think however they're 850watt options was too big for my case unfortunately. Thanks for the input though.
That is the power supply that got my hope up however its depth measurment was too high 10mm over I say the depth as it what Silverstone class as the limitation of the case for the power supply the 190mm is technically the depth the power supply is 86mm is the height of the power supply this seems pretty standard. However Different websites and manufactures can't seem to standardize the way they display what is the height, length and depth. Unfortunately the depth of this power supply would be 190mm which is 10mm over the maximum size it could be for my case. Thanks though Deders this would have probably been the best one if it fitted.
I have heard largely mixed reviews about the new Seasonic PSUs, many users have been complaining about serious coil whine in the New X-Series PSUs. (This ruled out the new Corsair PSUs based on this design) Another thing to consider is whether you're planning on sleeving the PSU cables, in which case I would again avoid the previously mentioned PSUs as their 24 pin out is atrocious and notoriously hard to sleeve (lots of double-pins and a mess of crossovers) For both these reasons I chose the Silverstone Strider Gold Evolution 1000W. The fan runs really quiet (I think it uses a Silverstone penetrator fan), with not a whisper of coil whine in my ridiculously quiet PC. Also comes with a dust filter, fully modular cables and is standard ATX PSU dimensions so it should fit in your case. A note: The PCI-express cables do come with capacitors on them. If sleeving these must be removed, however I haven't noticed any increase in coil whine from my graphics cards or PSU since removing them and the 24-pin pin-out is far superior to 99% of PSUs. "Oh, now we're talking. Silverstone, you can put bulky capacitors into my modular cables any day, if they help you get results like this. We have about 32mV on the 12V rail, and are at half spec on the two minor rails. This puts the Silverstone between the Kingwin LZP and the Seasonic Platinum for ripple suppression. It is better than the Seasonic, and comes within a hair of matching the Kingwin. Very nice indeed. I'm not sure I can quite allow it the zero point deduction I did with the Kingwin, as it's a little too far away from that magical 25mV or less number I'd like to see from the 12V shots, but it's still really close." - Johnny guru (Full review) Hope it helps
Your system. Hardwareluxx.de showed a system (using an overclocked i7-3960X - 130W TDP, so much more power hungry than an i7-3770K) and your card drawing 388W. http://www.hardwareluxx.de/index.php/artikel/hardware/grafikkarten/26748.html?start=8 So I don't see why you need an 850W PSU.
Hi MrTeal Heres a list of my current build and you will see at the moment 850 watts would not be necessary however plans in the future would be to eventually sli more ram etc . And I believe it would be an ill move to buy a power supply which would not be able to ready for any changes I make.

850Ws of overkill Cheesecake! However if you can keep your consumption below 50% load of some PSU's , then they shouldn't spin their fans (unless there's serious heat dissipation issues). If the load never goes over 475W (half a 850w PSU), even when everything is fully loaded, then the fans should never spin up. That's my logic. Added capacitor ageing over the 5+ years i'd keep a good psu for. And any possible upgrades down the line (sli/crossfire). Jobs a good un.
