GTX 980 on 400W psu?

[bpgt64]

Seasonic
http://www.newegg.com/Product/Product.aspx?Item=N82E16817151097

ITX motherboard, 2nd Gen i5 2400- No OC. In a Lian Li TU 200.

1 Solidstate, 1 2.5 inch drive, 2 fans, 140mm, CPU Fan.

Thoughts? Bad idea?

 

[Tallencor]

I think they are rated for min 500W

shouldn't have any issue on that Seasonic.

Except you need another 6 pin. You only get one with that psu, but the psu should handle the load no problem, especially combined with that CPU.

 

[Frick]

Yes. I wouldn't do it on my go-to cheap PSU (FSP 400-60APN), but on that no problem.

It's run a HD 6870 and a 6770 in the past, so I wasn't suuper worried, but still a bit of a risk yea? Especially since it will be powering a 4k panel, and 2 other monitors.

Not really, did you see all the power consumption charts for the review W1z did?

Its a damn fine psu but i would go with this http://www.newegg.com/Product/Product.aspx?Item=N82E16817151119

run it threw a wattage calc. and you will probably find that your rig calls for a min. 450 watt PSU. Your PSU will probably be fine but I for one never run my PSU's at the upper end as the upper end is no where near as efficient as the middle, just my 2 cents. I my self would run at least a decent 650 watt but I have always gone a bit of a bit more for myself. I do believe you will find ripple troubles at the hi end and you are even past the hi end but it is a top notch top quality PSU you have.
A top quality GPU should be paired correctly in my opinion!

I would also not overclock anything on that PSU with that hardware.

People actually pay attention to online wattage calculators? Hes got one of the best 400w PSUs money can buy, GTX980 just alone only consumes ~180w, ~95w for the CPU, and then couple more watts for the fans and drives and he will probably not consume more than 350w full system load. Not to mention hes not going to be running full load all the time, at idle hell consume very little watts. Doesnt sound like he will be overclocking the 980 at all either.

I know and you are correct about his PSU but I still wouldn't do it and wouldn't recommend it either. I agree to disagree on this one.

I agree but there is nothing wrong with online calcs you can do it there or in your head but the best thing is to test it yourself, only if u know what ur doing, or read other peoples tests. In my working exp i always go little bit more and it never bite my butt

It would probably work, but a 970 might be a safer bet if you want to stay safely within the restrictions of your PSU. I wouldn't want to over work the PSU too hard too long which is why I think the 970 might be a half decent cheaper alternative.

I would never consider a 400w PSU. Never. *

*unless is was for a SFF HTPC.

Maximum during gaming with an overclocked 4960x.

With an overclocked 4960x. I think you'll stay below 300W during load.

So that puts it in perspective and supports what I was saying all along. The i5 2400 consumes less power then a 4960x by quite a bit. Shoudn't have an issue when taking that into account.

shouldn't have any issue on that Seasonic.

+1. At all stock speeds it should be fine. It's a Seasonic. It will run its rated wattage for its warrantied lifetime gents.

Is it cutting it close... yep. But I would do it in a pinch.

Hell, I run a 295x2 and a 4930K (4.4GHZ) on a 750W PSU...

Seasonic units are top end units i have a 1250w gold xm2 series (xp3 platform like the 1200w platinum).

 

[EarthDog]

Riiight... which is why I said what I said...

 

[Keullo-e]

If it consumes 190W in furmark, then there's absolutely no problem with a quality PSU like that Seasonic.

I have a couple go/no go rules that I apply to PSU's.
First, does the PSU have the connectors that the system needs? In this case, the answer is no, but I don't think that's a problem, and I'll explain. They put an 8 pin PCI-e power connector on this PSU which is rated at 150 watts(for a total rating of 225 watts for the GPU when you take into account the 75 watts from the PCI-e slot). A person could split that 8 pin to 2x 6 pin(rated at 75 watts each) with something like this and be fine. The ASUS STRIX GeForce GTX 970 OC even comes with only 1 - 8 pin PCI-e connector, and it's too bad that others don't adapt that format. (this might be a nice choice instead of a 980)

Secondly, is the wattage rating for the GPU 1/2 of or less than the PSU's rating. In this case it is.
We are dealing with a high quality PSU here and I think that other manufacturers would rate it higher, at 500 or maybe even 550 watts. As long as the OP is not using this to bench with, I don't see a problem.

Actually, the problem is with the PSU manufacturers today. They want to push the 750+ watt PSU's but there is actually very little need for them. We need full featured PSU's starting at 350 watts now.

Especially since it will be powering a 4k panel, and 2 other monitors.

You've got me there. I don't think that matters, but I have to admit I don't know. grumble, grumble, off to ask Mr. Internet.

 

[D007]

I think they are rated for min 500W

They are and your psu is likely going to explode as a 400.

It's run a HD 6870 and a 6770 in the past, so I wasn't suuper worried, but still a bit of a risk yea? Especially since it will be powering a 4k panel, and 2 other monitors.

As for power usage of monitors/TV's.
That power comes from the wall socket, not your PC/PSU.

 

[OneMoar]

I would't not when a quality 620/650W can be had for ~80.00

@EarthDog ran a 690 on a 550W unit. Considering the single chips used more power than the current maxwell cards, I'd say he's fine to do it on a Seasonic, although the lack of PCIE cables on the PSU means Molex is required.

Sometimes I read your responses, and I..I just don't know what in the f.

They site a 500W minimum because there expecting you to overclock, and do this and that, and run other things. The PSU listed above is a champ, it's efficiency is second to few. Given PSU calc, I should be well within my means. Is it advisable? probably not, but if you use logic and add together the items I am planning on using, it should do just fine. I cited the 6870 and 6770 because they have similar PSU requirements.

I ran this GPU for 6 months with no issues on this PSU. But the GTX 980 brings new power requirements, which should actually be lower. I mention the resolution because the GPU generally is much more used at 4k even at desktop and idle.
