PSU for OC i7 3770k, SLI ASUS GTX 780's, and WC loop under 180mm in length?

post #1 of 7
Thread Starter 
I need to find a good PSU to fit my bill. I have a Switch 810 and plan on adding a 280mm rad on the bottom so that's why there is the < 180mm restriction.

I just bought 2 GTX 780's which I plan on overclocking as well as my 3770k.
Currently I have a 3 year old AX750 which is not quite enough for what I want.

Prefered color is Red/Gray/Black

So far I found the Enermax series PSU which seem to be alright but I want a quality PSU.

Thanks in advance!

The SilverStone Strider Gold is 140mm so that can fit for sure and its fully modular

Newegg has the 1200W at 7.09 inches which is 180mm. But yea something along those lines would be sweet!

You dont need more then 750 watts for two video cards

1200 watts could power 4

Keep using the AX750 unless the GTX 780 models can be overvolted a lot (I don't really follow graphics that much, but AFAIK Nvidia has been locking stuff down?) and you're doing nasty things to them on top of running stress tests all day.

Ivy Bridge is hot, but it doesn't use much power unless maybe you delidded or otherwise have very good cooling and then ran a bunch of voltage into it.

Don't need to baby an AX series power supply with loads usually well under capacity.

^ this pretty much. 3 yr old AX is still alot better then what alot of people are using biggrin.gif and you wont be stressing that PSU with only 2 GPU's. no point spending $ if you are already working with one of the best PSU's you can buy.

Hmm wow I would have never guessed. ASUS suggest I have a minimum of 1100W for my setup, but this is not the first time I've heard people tell me I should be fine with my 750W.

The Asus cards DO overvolt if you use the Hotwire. Unfortunately it requires some mods which void the warranty so I won't be doing that until maybe 2016 when the warranty is up wink.gif

Adding WC soon to the build with like 12+ fans. I don't know how much of a difference that will make to the power draw but I guess I will just have to go and see how things go.


Thanks guys!
