PSU big enough?

post #1 of 6
Thread Starter 
Hi guys! biggrin.gif

My current build allows only 9 inches behind one of my rads for the PSU.
So I really need to keep the PSU at 8 inch long, prederably 7 inch.
And I'll be getting 3 Titans, if they ever get back in stock somewhere.

With my size requirements, the biggest power PSU I could find is the Enermax 1350W PSU.
Great because I just happen to be an Enermax fanboi.

But partspicker.com tells me a 4930K with 3x Titans will run 1028W.
Add an other 100W for my pumps and 39 fans, and we are up to 1130 W.
HDDs, SSDs, and various other doodads will likely add an other 70W.
So we are now at 1200W!!!

How much more head room do I need if I ever want to get a good OC going on both my CPU and GPU's?
Is 150W sufficient?

Or is there a way I can run my water loop pumps and fans on some very small seperate 100W PSU to free up more power on the Enermax?

Or do you have an other PSU to suggest, with more wattage (1500W maybe) and less than 8 inch long?

Thanx for your help.

PCPartPicker is always wrong, on the high side. You will have way more than enough power unless you decide to overvolt the Titans to hell and back. If you leave their voltages at stock, then you'll have all the power that you need.

Well, dual boot. Mostly Ubuntu. Windoze for gaming and 3DsMax
But on this build I want to try my hand at CodeWeaver and WINE just to see if I can get any good games to run on Ubuntu. But I'll still be stuck on windoze due to 3DsMax and my lack of desire to learn Bender instead.

It will probably be Mint actually, not Ubuntu.

Might actually be a triple boot with with OSX if I can get it running to keep the wife happy......and just to say I did it.

Why you ask?

I just love Linux and can't wait until it is standard for all games to be on Linux, thank god valve and some other companies are making a push for it. Currently I run Ubuntu on my htpc/server rig and windoze on the desktop cause i'm a gamer at heart.

Anyway, thread is solved.
I'll just get my beloved Enermax 1350W PSU.
And if it's not enough, I'll just get this cute little PSU tucked away is a dark spot of the case to run my loop and other doodads, effectively freeing the Enermax for more power.
