Will too much Wattage be a problem?

[Scrulls]

Hello lads,

 

So I have a build that i am making and i sort of went for far too much wattage with it (already bought the PSU..  ) and i have a question or two here.

 

With the following parts: http://pcpartpicker.com/list/rC2BZ8

 

I bought the PSU with the idea that i will buy a second MSI GTX 1060 Gaming X 6GB to run in SLI with the first, but i did not account for how much it would need with just one. In PCPARTPICKER it says 332, so i roughly estimate it at a 400W (minimum) needed PSU for a single GPU, but with SLI, i suppose a 500-550W would also suffice.

 

My question here is, because my knowledge about PSU's is little to none, would using the Corsair CS750M 80+ Gold with that single GPU have any side effects or instability, or is every bit of power transfer handled by the Motherboard and its BIOS settings?

Or perhaps i am just worrying too much  

 

Side Note: I will be doing some overclocking on the CPU at a later date, but i when that time comes, ill be sure to check the forums here for any answers, or simply post should i have any questions.

 

In any case, cheers!

A PSU's wattage rating merely states how much it CAN provide, it doesn't mean it is always pushing that out. Your PSU will only push out as much power as your PC is "asking for". That being said, if you computer asks for more power than your PSU can provide, you'll have stability issues.

 

TL,DR: You can never have too big of a PSU.

You're good. The wattage doesn't mean it's always providing that much power - it just means that it can provide that much power if it has to.

 

Efficiency curves would be the only thing that make having a too-large PSU bad - if you're never getting to the point where it's efficient, you're wasting a little electricity. But it's not a big deal.

 

EDIT: Also, the 1060 doesn't have SLI fingers, so you can't put it in SLI. Just so you aren't disappointed later ;).

Yes, it's can be a problem to your bank account, not to your computer.

750W is pretty standard though, good luck with your rig!

First of all, thank you both for your opinions here, much appreciated (and i did not know you can actually "snip" quote a comment here, good to know...)

 

But i am pretty sure that the 1060's 3GB version does not support SLI fingers. As for the MSI Gaming X 6GB version of the 1060, it has full SLI support from what i have seen around the web (i think even Linus did a video on that matter)

 

As for electricity bills, i personally don't care if i even use a 1200W PSU as electricity is pretty cheap in my country and i dont really have a problem with the bills (always estimating with 100$ more than the necessary  )

 

Cheers,

The only problem that might be is that an overkillr PSU might be unefficient when using with low wattage needs. (Though I'm not talking about the real overkill PSU's such as 1000+W as they are usually 80+ platinum so they remain efficient)

It's overkill but it won't waste any power or anything like that. You'll be fine.

I figured the electrical bills didn't matter  just figured I'd mention it in case!

 

And as far as I can see, the 1060 doesn't have SLI fingers for any model. Can you show me where you saw it? This is what I can find.

You can check the whole GPU's architecture specs at MSI's website:

Heres the first pic that i saw from the lightshow showoffs at MSI:

Hm, that's strange. Every other picture I can find doesn't have them (even on MSI's website). I can find a bunch of articles on how the 1060 doesn't support SLI too. But hey, if it does, that's great news!

EDIT: My mistake, apparently there is no official SLI fingers for the 1060, but it is possible to use other means (although pretty unstable for sure), BUT i doubt ill be using such SLI for gaming, probably just simple benchmarking to impress friends and what not..  

 

so, excuse my mistake, im sort of still learning things as i go.

It's totally alright, don't apologize! I think what you're probably referring to is the new DX12 feature that forces two GPUs to work together (I forget what it's called). That has to be enabled by the developer though.

 

I totally understand, the learning process takes a long time! Good luck with your build, I hope it goes well.

but you should look at what load the PSU preforms the best at and get one that preforms its best at the point your hardware is at 85% load if you dont want to spend to much on getting 1000W just because its fine to do so(if you dont hate your bank account) but OP you are fine with that
