1080ti PSU requirements?

[Kasper_MC]

Hi peeps

 

I've been offered a Gigabyte Aorus 1080ti for an equal to 120 USD less than I can find it for other places from a friend who just want it gone fast and plans to put it online.

Anyway: I'm running a 2600X, 16GB DDR4 3000mhz and have a GTX 1070. 

I think it's worth the purchase - just to have it, if I wanna upgrade the CPU at some point. I mean: I have the money, and it's not gonna be worse than the 1070. But, here comes the proverbial but... I have a 620 watt PSU - a Seasonic 80+ bronze. I've looked at all the different PSU-calc's I could find online, they say anything from 440 watts to 637 watts for my rig with the 1080ti... so - how would it handle it, do you think?

Badly, get the whisper m 550W on newegg for $80 instead

[WereCat]

620W is fine

Group regulation is not fine

PSU calcs are pretty useless, a 1080ti is unlikely to pass 250W from a typical gaming load, your PSU is fine.

What's your monitor resolution/refresh rate?

It helps to list the make and model, although I believe there's only a couple seasonic 620 watt PSUs. Do you have the S12II?

 

There are affordable PSUs that would go with a 1080 ti, like a seasonic focus or bitfenix Formula gold. You can use a 550 watt PSU and it's more than enough.

Maybe not that one. What with the OCP problems, ripple, freezing, only 1 PEG connnector, noise and all... 

[XR6]

In terms of wattage you will likely be fine, although I don't think your PSU is good enough.

If you have a Seasonic S12/M12 then replace it. You don't want to be using a group regulated PSU with a high-end card like that..

[Kasper_MC]

My PSU is the M12II Evo edition. 
I drive a 1440P screen

I'm not planning to OC it

 

[Kasper_MC]

And thanks for the replies
Seems like it's just as not-straight-forward as the PSU-calc's made it seem. 
But it seems like, I could do it - but I should get something gold?

Hello_there_123, I have no idea what you're talking about - it's over my head - but would it do for a non-OC'ed?
It would be pretty pointless to pay out 100 dollars to save 120 dollars... then I might just wait with upgrading my GPU untill there's a fall in prices.

Seems like a good deal

Wattage isn't the Problem, Quality and how the PSU is working is.

 

You should get a different PSU.

What is available in your region?

No, its not.

As it points to some specific models that must not be used with highest end GPUs!

Chances are you will have to upgrade your PSU if you want better graphics card regardless, so it's no big loss

Its not recommended but it will work. He can upgrade later. If he can upgrade now, sure, he may as well do that. But it will work fine for the time being.

Besides, he havent mentioned the specific model before and I just said that the 620W enough, which is true.

And what if it doesn't?

The 1080ti is a high end GPU with some brutal Transients, wich can cause Problems.

To make it worse, the Seasonic S12II lacks some important protection as well.

...and kill his Computer with an unsuitable PSU, in a worst case scenario...

 

You know that the S12II/M12II up to 620W lack UVP on 12V, do you??

why not just admit that you were a bit too general and that the PSU he has isn't a great idea to be used with a high end Graphics card???

I used to think as such until I saw a friend who got a Vega FE and because of the "wattage is enough no hurry to get a decent PSU" mentality kept using his 2+ years old EVGA 600B1, used to power a GTX 970 and every one thought it'd be ok.

 

During peak load on the Vega FE the PSU did a small "blow up" with plenty of smoke now on his case the PSU died alone but we all know it's ridiculously easy to lose more hardware along side on these cases.

 

When it happens to someone you know irl you really start takng these things more seriously.

I was a bit too general because I wanted to be.

 

I said 620W is enough. I did not want to comment further but now you make me. You are right, he should go with a better PSU.

But many people are overexaggerating with PSU blowing up. I know this PSU lacks UVP, still, it will be fine. Its an old PSU but its far from being trash like some other units, thats why I am still saying it will be fine for the most part.

i'd make sure the 2600x isnt running something like 150w, keep it under 100, 1080 ti should be under 300w, it should be enough but a psu upgrade is still recommended.

Exactly, it won't hurt his system, but ideally he really needs to get a higher end unit, a good 650W PSU.

You have any proof of that?

Actual Measurement that a group regulated, badly protected 2010 PSU has no Problems with modern Components?

Oh, I see...

Because it lacks OCP anywhere and UVP on 12V, it can't switch off if there is something going on in the system, the 12V rail drops to 10V or something like that. Because it has no UVP...

You shouldn't, because Wattage is not very relevant, build quality of the PSU is...

And there are more than enough bad quality PSU, also some have 620W...

Again, the Wattage is not that important. A good quality 400-500W PSU is better than a low quality or group regulated 600-700W PSU...

So you're saying this "620W" PSU would be fine for the 1080ti?

Where is the disagreement?

Its not (just) PSU Blowing up, its also other Problem.

Such things as random reboots, switching off, PSU getting really really loud.

 

And at least the PSU getting really really loud is something that will happen as we're talking about 2000rpm or more with his unit...

You don't know that!

And that is the problem.

What is when its not fine? 
What is if he has randomf freezes, reboots or the PSU is far too loud to bear?

 

 

There are also other things. The sad thing is that bad PSU can kill components over a long period of time...

Why do you think that?

Thank you all for engaging so much! It's been a steep but interesting learning curve

I got to try the 1080ti before buying it - brought my system and a watt-meter with me, so did some tests. 
I ran Heaven (standard free edition), Firestrike, Firestrike Extreme, Time Spy, Time Spy Extreme (the dude had a 4k display, so why not..), Furmark stresstest (for approx. 10 mins), GTA V and Superposition - in that order. The total system draw from the wall was at no point more than 450 watts: 450/620*100=72,6% use on the PSU (mostly it was around 400 watts, GTA was 293 at most). The card never got to more than 73 degrees celcius, closed up inside my RL06 case.

Also, the thing about it not having UVP - it does, at least according to Seasonic: https://seasonic.com/m12ii-evo#specification

I'll keep monitoring watt, temp and voltages for a while and report back if anything happens. 

Thank you all for your help So far, I'm a happy camper.... let's see for how long... 

Btw: the scores equaled about a 25-40% uplift to my previous GPU.

On 3,3V and 5V, not on 12V.

Here Review:

https://ru.gecid.com/power/seasonic_m12ii-520_bronze_evo_edition_ss-520gm2_2015/?s=all

 

You can see that they use the HY-510N for wich you can google a Datasheet.

And there it shows that there is no UVP on 12V.

A WT7502 for example does come with UVP.

 

Here another Review from a labeled unit (and Seasonic doesn't allow many changes, so yours is similar):

The XFX (zweite Revision) is the Seasonic made one.
