Power Consumption for R9 Fury (non-x)

[ryderbg]

Hi! Is there any difference in between graphic cards makers in talking about Power Requirments?
I noticed that there is different requirments for R9 Fury.

For Gigabyte R9 Fury is 600W PSU. Source: http://www.gigabyte.com/products/product-page.aspx?pid=5680#kf

For PowerColor R9 Fury is 750W PSU. Source: http://www.powercolor.com/us/products_features.asp?id=594#Specification

For Sapphire R9 Fury is 750W PSU. Source: http://www.sapphiretech.com/productdetial.asp?pid=B962294E-9DBC-470E-A817-46EC0AA5B14A&lang=eng

So is there a mistake in Gigabyte's specification or there a difference between the cards which should be exactly the same.

Under normal gaming use the card will use around 200-250 watts. A torture test with a Fury and i7 caps at about 400 watts. A good 600-650 watt PSU should be plenty. Some card makers over-provision to account for peoples poor choices when it comes to choosing a quality PSU suitable for high end gaming.

A good quality 600w is a safe option.

This is mine - https://scontent-frt3-1.xx.fbcdn.net/v/t34.0-12/13101531_10205510605475607_1254960254_n.jpg?oh=d1c546d5ce6c867f5be8cc35062d8082&oe=572E6C5E
I don't know if it's good or not, but it came with the case. Also I have i7-4790k which is around 90W.

Thats basically a 400w psu (look at the wattage on the 12v rails).

You should replace that with a good 600 by Seasonic/Superflower/EVGA/XFX etc.

Ok. Thanks!

What if I take R9 Nano? It is much less power hungry and the performance is the same.

 

[RobCrezz]

Its basically the same GPU, but with a lower power limit in the bios, so when the cards are heavily loaded the Fury does pull ahead (albeit not by a huge margin).

I would still change the PSU to be honest, 400w on the 12v rail is quite limiting, a gtx 970 would be the highest card I would use on that.

I was thinking a lot and going to add a second card in near future. So Nano is not an option anymore. For 2 Furys what PSU would prefer? In our local shop there are plenty of Cooler Master, Corsair, Fortron, Fractal Design and Seasonic. I stopped on this 850W - http://www.seasonicusa.com/M12II-Bronze-650-750-850.htm
Is it good enough to handle 2 of R9 Fury?

Actually you should be using 1KW power supply for Fury crossfire. Seasonic is a great brand.
