PSU Suggestions

post #1 of 15
Thread Starter 
Hi,

Ive been looking at quite a few psu calculators and some similar builds to mine. Im still unsure of what wattage psu i should upgrade to. Im in the market for a 850w but im not sure if it will be enough and if i have to go to 1000w. I am currently using a Corsair HX750 here is my current component list.

CPU: 3770k @ 4.8
GPUs: GTX 770
RAM: x4/8gb 32gb ram
Storage: X2 SSDs
Cooling: D5 Water pump, x6 SP 120mm Fans
USB: x5 Devices

I just got my new parts in to upgrade my system so I will be adding another graphics card and changing the mb and cpu. Once I finish my new coolant lines and decide on my PSU the list should be as follows.


CPU: 4930k
GPUs: x2 GTX 770
RAM: x4/8gb 32gb ram
Storage: X2 SSDs
Cooling: D5 Water pump, x6 SP 120mm Fans
USB: x5 Devices

will 850w be enough for this or do i need to go to 1000w?

There at least two psu gurus here. I'm sure as long as this thread gets bumped a couple times, someone more knowledgeable than me will reply-

well if it was me I would go for the 1000w. better to be safe and have a little more then you need.
I run a 1200w myself but I use to have 2 GTX 580's but now only 1 GTX 680 but I can't see taking out my psu just to save a little on my electric bill.

Sory i was sleeping while this thread was started.

Anyway if you are not going to overvolt your video cards you can go as low as 650 watts for that system so lets say 750 watts, only if you are going to overvolt would you be looking at a 1000 watts.

I will say EVGA SuperNova G2 750 watts the reason why is explained here
