550W PSU for 2GPU-s??

[CGT]

Hello there, i want to know if my 550W PSU could support my ideea:

CPU: i3 2100

GPU1:GTX 550Ti

GPU2:RX 580 GTS XXX

HDD: SAMSUNG EVO 256

I will use them for graphic rendering..

Why would you ever bother with the GTX 550 Ti?

 

What graphical rendering? what software?

 

What 550W PSU specifically?

that bordeline intel UHD graphics. why bother?

 

its insignificant in comparison to the rx 580

[LienusLateTips]

What PSU, and why a 550 Ti?

Segotep GTR-550 550W

 WHY a 550ti? because i use DAZ 3D and daz does not support AMD

Change that, even with only 1 GPU....

The 550 Ti is ridiculously slow. It's almost as slow as your integrated graphics. It's a waste of energy....

The PSU it has 85+ efficiency...

• OVP/OCP/SCP,
• Active PFC,
• ATX 2.31
• Silent Cooler

Does not matter. It is a cheap, no name Chinese unit, that according to your own list, does not even have OPP.

Indeed IRAY is CUDA based and will only hardware accelerate through CUDA.

 

So........ why'd you buy a RX580 to begin with? The GTX 550 Ti is ridiculously slow and will hardly if at all help to the point you might be better off just with CPU doing all the work... or sell the RX 580 and afford a GTX 1060 or something.

This unit would break if you tried to force it to run 2 video cards at the same time.

Worked fine until now, like 2 years of rendering in Blender no problems, but the 550ti is better that i3-2100

It's missing the most critical safety protection, that shuts it down when overloaded instead of exploding and taking components with it, and possibly even you.

 

With this PSU, you are risking both your components and your life.

 

 

Sell the 590, get a 1060 6G....

Why 580? because it's better than 1060 in blender , and DAZ3D i use rarely..

Well then, these would be your options:

 

See if it's worth getting a quality 650W-750W PSU for the 550 Ti combo

Switch to a 1060 6G, and get an actual 450-550W quality PSU.

Stay with the RX 580/590, still get a quality PSU, and have DAZ3D render slowly.

i will probably put both in the same PSU and see an explosion =))) , Corsair VS Series VS550 looks decent, or change the video graphics card everytime i use daz, and day to day use rx 580

You probably won't see that right away but there is a chance of it happening.

 

I would still highly advise against it....

CX550, bare minimum. The VS is still a group regulated unit, although it has all working protections.

[Do you really wanna know]

No, just no!

 

A PSU operates at peak efficiency of 60% of max load, and you're wanting to max out a 550 watt PSU. Bearing in mind that a PSU will lose at least 5% efficiency per year, (much more when you're at or near 100% load), then no!

So if you buy a 1200W PSU in 12 years it's DONE! AND DUSTED! :)) lol k

Is this any good? https://www.amazon.de/dp/B017NW4P1M/?SubscriptionId=AKIAJCMZ7EUWHXU3XRZQ&tag=xov-de-21&linkCode=xm2&th=1

 

And with 1GPU  rx 580..

That's nonsense. Overestimates to hell.

Yes, quite high quality.

It'll use at most 350W.

[Fasauceome]

It looks like you're aiming for best of both worlds on all fronts here, you wanna keep the cheapo GTX card for software you rarely use, wanna keep the 580 for blender and you wanna keep your cheapo PSU because a decent one is not super inexpensive. You have to make some kind of concession.

 

Is a CX450 really too expensive?

[airdeano]

yeah, personal attacks will not be acceptable here. wanna stay, knock it off.. wanna leave, we can help with that, too..

thread cleaned.

i calculated 365

I've run an 8700K and Vega 64 on a CX450M before. That'll be fine on 350. Not that any quality 350 units are readily available on the market.

Yeah, but you can't add up and have difficulty understanding what words and numbers mean... LOL!

You REALLY aren't being helpful right now.

Oh, and the Gamers Nexus video will always confirm how wrong you are, no matter how much poo you post anywhere - ROTFLMFAO!

Now, if you can see here, from Tom's (EXTREMELY detailed PSU reviews)

 

230V peaks at 92%, when near max falls to 91% and when at ultra high load goes down to 90.5%.

Typically, your power supply's maximum efficiency is between 40% and 60% of it's maximum capability.
