Bitfenix WHISPER M SERIES 850W

They are excellent psu's and are built by CWT who also make a lot of Corsair units including the good ones such as the RMx series. This is a brand new platform though and has been getting some very good reviews. It has the full 850w available across it's quad 12v rails. Each rail is dedicated to a certain group of components:-

12v1 Motherboard and peripherals
12v2 CPU
12v3 GPU 1
12v4 GPU 2

There is a review here. The downside is that the 24 pin ATX lead has a large cover over it, see here. I suppose it's there to cover the capacitors. If you can live with it then it shouldn't put you off buying what is a very good psu.
 
Thanks.

I'm a little concerned at the comment regarding noise at heavy load... this will be powering a 6700k @ 4.4 and 1080ti @ 2050MHz.

I would estimate a total power draw of around 600-650w during gaming sessions, and with my GPU being under a custom loop then the PSU might end being the noisiest part of the system at that power draw.

My alternative is a Super Flower 850w Gold rated @ approx. £125 so there's certainly a big cost saving with the Bitfenix.
 
@lee32uk the recommended PSU for the EVGA FE 1080ti is 600w?

I'll plug my power meter in and see what it's actually drawing, as it sounds like EVGA may have over egged the power requirements.

That is just the manufacturers recommendation. They over exaggerate it to compensate for people using potatoes as psu's :D

This Anandtech review of a 1080ti FE shows it with an i7 4960X @ 4.2GHz pulling 403W under gaming load (Crysis 3) for the full system:

As Lee has said, you won't get anywhere near 600w. The pc in my siggy along with several fans, temp sensors, 2x fan controllers and all the watercooling stuff hit a max of just under 300w at the wall when benching with the gpu heavily overclocked. This is with the cpu and memory overclocked as well. Normal gaming use is no more than 252w at the wall. Manufacturers heavily overstate psu requirements because of the people who are running crap psu's.
 
I posted this in the GPU section, but had forgotten about this thread.

I assume this is enough headroom to ensure the PSU fan isn't kicking in and ruining my silent water cooled set up?

Leadex Platinum 850W Fully Modular "80 Plus Platinum" Power Supply

https://www.overclockers.co.uk/supe...platinum-power-supply-gunmetal-ca-049-sf.html

It's a decent price, and this PC is on 24/7 so the platinum rating is an advantage.

To recap, spec is:

  • 6700k @ 4.4
  • Gene VIII
  • 1080ti @ 2050
  • 1 HDD
  • 2 SSD
  • Water Pump
  • 6 * 120mm fans
 
I believe the fan kicks in when the unit reaches around 45 degrees C. I doubt that you would even get near 400w at the wall even with everything overclocked so it's hardly going to tax a 850w unit. I have to say that I have never heard my Seasonic G series psu's fan at all and that has no fancy hybrid mode. The only way to guarantee total silence though is to buy a fanless psu.

If I were looking at a 850w Platinum unit then I would be paying the extra £13 for the EVGA P2 850w to get rid of those awful bright white led's and to gain the extra 5 years warranty (Superflower is 5 years, EVGA is 10 years even though it's basically the same unit inside). EVGA's customer service is excellent as well and now they also have a UK RMA centre.
 
I opted for the Super Flower Leadex II 850W 80 Plus Gold and have been using it since early June. Unfortunately, while it isn't overly noisy it's the loudest component in my rig. I've put a lot of effort into moving my radiator and fans into my garage, and this PSU is now doing my head in.

How much over 850w do I need to go to ensure a silent PSU? Is there a brand famed for it's silent running?

Spec is 6700k/1080ti
 
And, that was the problem apparently. :mad:

I just switched eco mode off and it's now quiet. Eco mode had the fan either off or ramped up.

All's well that ends well and my system is now super quiet. I'm glad I didn't buy another PSU. :)

Yeah eco mode can be a bit hit and miss. Glad it is sorted though :)
