Upgrading to 980 ti

[antonisk]

So i m thinking of purchasing http://www.scan.co.uk/products/6gb-g...st-1317mhz-cor and my main concerns are:

Will it fit my Corsair Carbide 500R Mid case?
My PSU Corsair TX750M Enthusiast Series is 4 years old now, is it still good enough even if my i5 2500k is overcloked at 4.3 ghz.

I'm only gonna be running one so i m guessing i shouldn't be concerned with PCie lanes. My motherboard is Asus p8Z68-v pro Gen 3!

Let me know your thoughts.

Your psu will be more than enough for your setup with that gpu. I doubt if you would be pulling more than 400w at the wall.

Your case can take gpu's up to 452mm in length with one of the hdd bays removed but you shouldn't need to do that as reviews show the actual card to be no longer than a atx motherboard's width. You could then fit the radiator in the rear exhaust fan position or in the roof.

Pci-e lanes you are limited to pci-e 2.0 16x as pci-e 3.0 only arrived with Ivybridge cpus (pci-e controller is on the cpu). You are highly unlikely to notice any difference apart from maybe a few percent in benchmarks. If you really want pci-e 3.0 then you need a Ivybridge cpu but personally I don't think it's worth changing.

Thanks alot pastymuncher, I m more confident now. I was also considering 2 gtx 970 in sli, but too much hassle, more heat and noise.

Even they would have been fine with your psu. Reviews show sli 970's to only draw around 450w at the wall. The 900 series are incredibly efficient cards. My pc with a single GTX 780 has a peak power draw of 452w at the wall.

The 900 series are incredibly efficient cards.

But they do have massive power draw and heat output. A top of the range i7-6700k draws perhaps 80W at full load. The corresponding top of the range GTX 980ti draws at least three times that.

Compare the situation 11 years ago:

How on earth is that a fair comparison? That's like comparing a penny farthing to a Moto GP bike. Cards these days are massively more powerful than cards from 11 years ago and todays low end card or even Intels onboard gpu is probably more powerful than a high end card from back then. The GTX 900 series run rings around anything else available at the moment with regards to power efficiency. I could run a pair of GTX970's and draw no more power (potentially even less power) than my single GTX780.

Will it fit my Corsair Carbide 500R Mid case?

It will fit in my 500R, so I would assume so...

So is every other component, but they haven't had a three or four fold increase in power consumption. Intel's eight core i7-5960X is similar power to the original single core Pentium 4 Extreme Edition, also from 2004.

The computational requirements of games are arbitrary and solely based on the available hardware. When people are making enjoyable games on GPUs drawing no more than 2-3W for smartphones, calling a 250W gaming card efficient is more than a little absurd.

It's efficient in a technical sense of computational power per watt, but is it efficient to use a 250W device for entertainment purposes when there's nothing except inertia stopping that being a 75W device?

As customers we don't have a lot of control over the situation unless a lot of us get together and refuse to buy anything that uses more power than necessary, most of it will be down to the game developers unless AMD and nVidia agree a reduction in power plan to fight off Intel. Your comment just prompted me to want to provide a bit of wider perspective.

Are you suggesting customers buy cards that use more power than they're happy with? Power usage is one factor of my purchasing decision so I already vote with my wallet.

I was told not to get an EVGA 1600w PSU because apparently it's overkil... or something like that...
I'm like the Jeremy Clarkson of PC modding - "POWAAAAAAAAAAAAAHHHHHHHHHH!!!!!!!!!!"

Nah, seriously, I only have a 1000w Supernova G2...

You should be fine, I have a GTX 780, supposedly the same TDP as a 980TI - and I run it with a 4.6Ghz 4790k just fine, never pulling more than 400-450 from the wall. The 500R is a huge case and should fit it fine, check the manufacturer dimensions.

[Sean473]

Hp does the 4790K + 980ti in their Envy 750 desktop with a 600W PSU... 1000W PSU should be fine although a 850W is more than enough!
