Hi everybody! I have a question I'm curious on.

 

I have a high quality, gold rated 630w corsair powersupply.

 

With my 4K monitor, it seems more and more one GTX 980 isn't enough. I'm thinking about SLIing.

 

It would be nice if I didn't strictly -require- a new PSU though.

 

What are your thoughts?

 

Thank you everybody in advance for your input.

It will work but you wont have room to OC and you will be pushing that PSU to its limits very hard. I would not recommend runing it for extended periods of time with that PSU.

It should work as a temporary solution though.

You should be able to run it off a 630watt psu.

An AMD cpu has no place in a solely gaming build, end of.

I would say no, 700w would be fine, I think 630 is too close or not enough

I see. Would it make a difference if I told you I didn't have a mechanical HDD or a DVD drive?

While you might have enough power(without overclocking CPU or GPU) I doubt that the PSU would have enough PCIe cables for it and even if it does having a bit more than you need never hurts.

That wont help you much.

When gaming and you will run everything on stock you should take around 550W from wall and get occasional spikes to 600W. That said, it will work on stock and while gaming. But I would not run any benchmakrs with that PSU as it will put heavy load on your GPUs and you would easily go over 600W hiting the power limits very hard.

You can use that temporarily before you get new PSU though. The thing is also that your system may not boot when you put another GPU in your PC. It really depends on the quality of the PSU.

While it would be able to run at it's stock speed if you overclocked them then you would probably start to run into some problems and HDD only add about 15 watts of power so there is no real difference.

Heyyo,

go to this site and punch in the parts for your PC

www.pcpartpicker.com

It should give you an estimated wattage. You'll want a MINIMUM of 10% above that since you never want your PSU to be at full load as it'll produce extra heat, not be power efficient and lower the life of the PSU.

For example? Here's my PC:

https://pcpartpicker.com/p/786NZL

653 Watts is my estimated power usage under load, so my minimum recommended PSU is 719 Watts. I went extra above that to never risk a power issue and give myself overclocking room if I really wanted it so I am using an 850 Watt 80+ Bronze PSU. You could spend extra for gold or platinum but they won't save you crazy amounts of money unless you keep the PSU for something like seven to ten years.

So yeah, I went extra so my PSU should only ever see about 70% load but that places me well within my safety blanket thus my 850 Watt 80+ Bronze PSU should live a happy long life. :)

Another thing to think about? If you buy a bigger PSU? In the future if you upgrade your PC to an even more power hungry build? It should still have room to grow. ;)

Can you do it? Maybe.

Is it safe? No.

 

I recommend getting an EVGA if you are on budget, or a Be Quiet! if you still demand silence. Lepa is also quite big on the PSU's, but not too well known around the globe, look at reviews of them.

Basic guide to CPU's!

If I said I were 14, you would call me a kid. If I say 70, you’ll entitle me too old. If I say 20 you say I’m inexperienced and if I say 40 than I'm too boring.

If it's actually a good quality PSU then it will be perfectly fine. Everyone just spitting out that it's not are wrong. Here's proof.

That's pretty comforting!

 

As you can see, there's a bit of dissonance, a lot of people think one way and a lot the other.

The thing is taht it is REFERENCE 980, it is well known that aftermarket cards eat up more power. For example Gigabyte G1 gaming can take up to 50-70W more power than reference one.
