Two GTX 470's on 600W PSU?

[Brennan Price]

Hello there,

 

I currently am in the process of upgrading the GPU in my system from an HD 5830 1GB to a GTX 470 1.28GB, however, I have 3 monitors hooked up to my current system and the GTX 470 does not allow for this unless I have two GTX 470's in SLI.

 

So my question is, can I put two GTX 470's on my 600W power supply?

 

The 12V rail has 46Amps on it and the power supply states that it can output 552W on this.

 

I am guessing that I will be alright?

 

Thanks, Brennan Price.

at around 220W per card then in theory yeah, as long as you have the pcie connectors needed.

[Ashiella]

it will likely be just fine, i have an x5650 @ 4.4ghz and a hybrid gtx 580 highly overclocked with the power limit taken off (yes, you can do that.) on a 500w psu, its draw is around 450w max load. Running aida 64

In theory you can do what you say but there are the factors going against it.

- Power supply wattage isn't everything, what is the actual model of the PSU?
- GTX 470 architecture is old and will fall behind in newer games demanding high vRAM.  Throw in SLI and I think you won't be happy with that.  Unless you purely care about older games.
- 3 monitors is possible with mixed video cards - provided you don't plan on gaming across the three monitors.

Thanks, I guess I should be alright then @ImNotThere . I can buy Molex to 6 pins connectors for the second GPU.

 

I also have an X5670 running in my system so it's good to see you have a similar system and power draw @Ashiella

i would suggest 2x sata to 6pin.

 

yeh, i gotchu. (You used to hate me.)

Thanks, the actual model is the Aerocool Integrator 600W (Link below)

If I was to not use two GTX 470's I would use the lower end card to power my outer two monitors and I'd use the 470 to run my main 1080p monitor.

600w is too low.

430W for your GPU (non OC) will leave you 120W for CPU and everything else which need 12V.

Sure that  you want to buy this heater? they only have 1gb ram

Thanks, that is very true, especially as I still need to overclock my Xeon. Also, I have found that the GTX 470 though lives up to its name as a space heater in various other rigs, it does not so in my own. I have a good amount of airflow in my case and I have seen it reach 82-degree max with a large amount of dust still on the card from the previous owner. I have just cleaned it and when I test it again it shall be a much lower value I am sure.

I would try that first over SLI if it's cheaper and safer for your PSU, but don't expect that much of an upgrade in terms of performance, unless it's games from that era.

Thanks, I thought it worth asking first before I went ahead with it.  My PSU's high amperage clearly doesn't make too much difference.

i'd sell off the 470 and get a different gpu with the money if possible, that vram's very limiting nowadays.

No, currently I just want a little bit of a performance boost in games such as CSGO, rocket league, and robocraft etc. The 5830 is rather good for most titles but I seem to get 50FPS average in RL and I want to get over 100FPS in CSGO. I got the 470 for £20 so not much was lost.

Just out of pure curiosity, why such old gpu's?

I don't have that much money, I spent most of my budget on my CPU/mobo combo and I don't play many AAA titles anyway

Sorry, I didn't see the other post about getting it for £20.

Haha no worries, was a great deal in all honesty. One guy suggested selling it, now I kinda think the same but I could put it into a cheap build from spare parts. Not all is lost.

no you can't...those cards are very power hungry and doing SLI of these old bitches would require a premium quality 750W power supply unit.

Just sell the 470 and buy a new card instead.

Ah I see, I did think that a 600W may not be worthy. I could sell the 470 but I've only just got it haha. I could potentially keep it for another rig I am building but that may take a while.

Honestly the small amount of vram and the performance per watt  would make me look elsewhere, but if there aren't better deals to be had it can get the job done. If you want a cheap sli setup that is easier to run i'd look at used GTX 760's, specifically the 4gb models if you can find them.

The thing is, I am not specifically looking for an SLI set up. It's just that I would have to have an SLI set up so I can use 3 monitors with a GTX 470. I just need something to get me through games until I can afford something like a 1050Ti or 1060 much later down the line.

If you don't SLI the second GPU idles nearly 100% of the time.

 

Windows will simply render everything on GPU1 and copy the images for the other monitors to GPU2.

 

For games though, you will require SLI AFAIK to get the game on all three screens.  At least with cards that old.
