Power Consumption Rig

[RafaelLC]

Hey folks, i have my rig already built, based on my own research. I must say that this was my first ever build and i didn't know where to start off but what is done is done. So i wonder what do i need to change to upgrade this to a GTX970 SLI Rig (afraid of power consumption) and if there is anything critical to my system with what i have right now. I'm OCing this I5 to 4.4Ghz and memory voltage to 1.680 keeping the Core Voltage at 1.200, temps around 28~32 idle and 40~45 (sometimes 50) pushing Far Cry 4 up to Very High - Ultra, no errors, no breaks or freezes, am i doing this right? i'm OCing based on what i see aroung here and i must say you are a great help, thanks.

Best regards

you would need better quality/higher wattage PSU such as 750 watt evga g2 to support sli 970s

about the rig, have i done anything wrong? thanks for the answer

btw any substitute for EVGA?

didnt do anything wrong per say but could have saved some $ on few parts and PSU was low quality.

i had to change my case because h100i was a little bigger than what i thought but maybe i should have decrease the quality of the cooler and keep the other choice i had for the case, that was the NOX Green Goblin case, but i'll look up the PSU and find a good one this time

power consumption will be about 2x more then gtx 980. You should get a better PSU. A 850 would probably be the best to save power, since it would be about the double of the energy you will be using while playing, but not if your PC stays on for long times while idle.

So EVGA SUPERNOVA 850 G2 850W 80PLUS GOLD this would be enough?

Even a high quality 650w PSU would be enough.

A 850w PSU is good if you are planing to use your PC most of the time for gaming or any other demanding task.

PSU efficiency tend to decrease as the wattage increases.

If you will spend many time surfing, watching videos, etc, you might want to consider a very high quality 650 or even 600w PSU, since they will probably have better efficiency at low power consumption states compared to a 850w PSU.

I foud this formula on the web that alows you to calculate how mutch you can save between each PSU.

Annual savings = Energy usage (watts / 1,000) x Efficiency gain (%) x Electricity cost ($ per KW hour) x Time used (hours per year)

I think you can also swap "Energy usage (watts / 1,000) x Efficiency gain (%)" to "average watts difference / 1000"

EDIT: That PSU seems to be very good - http://www.techpowerup.com/reviews/EVGA/SuperNOVA_G2_850/7.html

I use my computer around 8-12 hours a day, on my days off i use 12+. Around that i watch streams (short version) 4 hours, wich gives me 8-10h of gaming at high quality, pushing the graphics to the max, always trying to achieve the soft spot between graphics and performance without having any freezes or lag, but i'm on budget sort of speak, so i can only buy very good things once in a while, but when i do, i want to spend it well. So will that EVGA do the job or should i go for a corsair AX-860 860W that is high rated on the same website you sent me? Assuming that GTX970 SLI is the best option comparing price/quality at the moment since i already have one GTX970.

How much is the your energy cost?

Personally I would go for a GTX 980 + Seasonic Platinum Series Fanless 520 W, but GTX 970 SLI is probably a bit more future proof, specially if you're not planing on buying a new PC for the next 6+ years:

Regarding PSU: any off them (EVGA and CORSAIR) would be great. And if you are on a budget, you should pick the EVGA. Btw, the EVGA G2 seems to have better reviews at newegg (5 stars against 4). You can read some of the review there and see if you can find more info that can help you decide (if newegg.com does not work for you, try newegg.ca).


Regarding GPU: this tread might be helpful: http://www.tomshardware.com/answers/id-2363050/4790k-gtx-970-4690k-gtx-980.html

More Honorable Mentions: Assorted Multi-Card Configurations

At $550, the GeForce GTX 980 delivers such compelling frame rates that we find it hard to recommend multi-card configurations able to serve up better performance per dollar, since they sometimes suffer from inconsistent results in comparison to a graphics cardwith a single GPU.

We'll call out some of the most viable options though, mostly for folks who are running high-resolution triple-monitor setups or 4K displays: two Radeon R9 290 cards for $540, two Radeon R9 290Xs in Xfire or GeForce GTX 970s in SLI for $660, and finally two GeForce GTX 980 cards for $1100.

To complicate things more, there is no big difference between GTX 970 and GTX 980 when playing Far Cry 4. (http://www.tomshardware.com/reviews/far-cry-4-benchmark-performance-review,4019-5.html)

Finally you can always search for videos with far cry 4 and gtx 970 SLI or GTX 980.
