How hard would you overkill?

[FairMaiden]

So I am at a crossroads,

 

After consulting this (http://i.imgur.com/tgrbCnr.jpg), witch i hope is good, for the following config, http://pcpartpicker.com/list/yHWjXH (I do plan on adding another GPU in the future), I can go for a  

1. Cooler Master V-Series V850, 80+ Gold 850W for about 190USD , or

2. Sirtec - High Power Astro GD 1200W  - 3 months used for 118USD

 

How overkill do you think it is just to save some money? will the 1200W psu reach it's 40% to work at an ok rate?

650w is plenty unless you go CF or SLI... (just make sure it is tier 1 or tier 2) hehehe

[jjbone1000]

Even with SLI max would be 700W

Cooler Master V850 is overpriced as fuck 

 

and why do you need a 1200W power supply again?

 

Get yourself a nice EVGA G2 750W 

and if you got the money (since you can spend $190 on that cooler master thing) get yourself a EVGA P2 750W

For two 980tis 800W or so is the general recommended amount for overclocking headroom. Of the ones you listed the V850 makes the most sense but, and I feel like a broken record at this point, the EVGA GS/G2 850W are a much better way to spend your money here. You could also go for the Corsair RMi for a bit more and get a few features built into the Link software and also the awesome flat 24-pin.

Ingore all of the tier lists, they all have gapping flaws. If you want accurate information about how good a PSU is and all of the flaws and pros it has is you are just going to have to do it the hard way and research reviews and all of terms.

 

That Coolmaster PSU is insanely overpriced and that Astro is capable of getting INSANELY hot and has what I would call average to decent. Despite people saying 700 watts or even 850 watts is enough you will definitely want a killowatt unit for a overclock i7 5820K which is capable of using close to 300 watts itself depending on how much voltage and how high you overclock and the GPU's will do around 250Wish each so that is 800 watts just with those 3 parts. If I was you and you are in the US I would go for a kilowwatt Corsair RMx.

ok something funny is happening when i try to quote....

So I was looking at a XFX XRT 750w 80G+, after i used the coolermaster calculator(and on the johnny guru forums), and it told me that it will be around 700w , so do you think the 750 is to low? i saw that the gtx1080 peaks at 200w OCed now i will also look at the i7-5820k overclocked

 

I would have the alternatives to go for a XFX XRT 850w 80G+ or a EVGA GQ 850W, 80+ Gold(both for around 125USD). What would you chose?

Lets say you overclock the CPU to 4.4Ghz at 1.3V.

 

That would be 140W * (4400/3200)*(1.3/1.050)^2 = ~295W of power usage with it at full load. Now now lets add in the GPU's.According to Nvidia they have a TDP of 250W so that is almost 800W with the system at absolute full load.  If you didn't overclock the CPU high as it could go, not sure why you wouldn't since you are on a enthusiast  platform/socket, it would be probably about 650W for those 3 parts and maybe 700W at max for the whole system.
