Would 1000w be overkill?

[Twiztid Loki]

I am new to building computers and I'm about to give it my first go in a couple of months. I have everything picked out that I want to use, including a 1000w power supply. I have recently been told tho that that would be overkill. How can you tell what is good and what is much BEFORE you buy it? I can let you know the components I'm going with too if that would help.

its way overkill. how many graphics cards are you running? I could only recommend 1000 watts if you had a dual cpus, or 3 graphics cards. part list would be great!

Letting us know the components is the way to tell.

 

Edit: In my case I have the AX 860i with 2 Cards and it runs perfectly, imagine with the new 900 series cards which draw even less power.

1000 watt is way over kill for the average computer builder. Unless your doing tri crossfire 290x or 4 sli 970 other than that your not going to need 1000w, PCs are getting more and more efficient as time progresses.

I have a 1000W Corsair PSU. It's overkill. But, if you look at the performance curve of any PSU, you'll see the best performance/efficiency generally is in the 60-80% or so range. I'd rather have a 1000W PSU running at lower loads than a lower wattage PSU running at higher loads. But that's just me. I'm also going to be upgrading to at a multi-GPU setup this summer probably, so I'd rather have the wattage now than have to buy a new PSU.

Tell us the components and we will tell you if it's overkill

Compnents: ASUS Rampage V Extreme LGA-Motherboard, Intel Core i7-5820K Haswell-E 6-Core 3.3GHz-CPU, EVGA 04G-2982-KR GeForce GTX 980 Superclocked 4GB 256-Bit DDR5 PCI Express 3.0-GPU, Corsair Hydro Series H90 High Performance Water/Liquid CPU Cooler 140mm, Intel 730 Series SSD 480GB along with 2 4TB HDD, RAID 1 configuration with the HDD's, Corsair Dominator Platinum 16GB (4x4) ddr4 ram. Kayboard mouse speakers etc is kinda still up for grabs so to speak. do plan on adding a custom  water/liquid cooling setup along with led's and possibly another GPU of the same kind later on. I woulod like a power supply that will be good for my final build but thats not complete overkill at first.

I would also like to do dual CPU's at some poimt maybe a year or so later. If Tower maters Im goint to get the Cooler Master HAF X.

Duel CPU or GPU?

[Norman_the_Owl]

If you want to use 390x when they become available you'll need it for sure.

 

Hell, even 290x. 850w is just not enough for 290x in crossfire

duel cpu and gpu

duel cpu and gpu

What dual gpu's are you talking about?

dual 7990s or two 295x2

or are you talking about dual 980/970s

If you are going with dual xeons and dual 7990s then you will not have enough power but if your going with dual 980s then you will

[AlwaysFSX]

You'll be fine with 750W no problem giving you room to upgrade too.

750 watt PSU should be more than enough and u would be able to get a second 980

[Twiztid Loki]

Sweet thanks guys!! Would the 750 watt give me enough room to upgrade later on without pushing it too much too?

[Hatsune Miku 「 」]

You can't do dual cpu with that motherboard and processor and dual xeons >$1000 + the new dual socket motherboard

Yes. With 750 watts you would be able to get a second 980
