Power and Motherboard will sustain a 280X?? 750W too much for single gpu?

ACidBaseD · Oct 27, 2013

Hello.
I am looking forward to buy a Sapphire Dual-X R9 280X , but the power requirement for it on the official page is given as 750W [Isn't it a bit too high for a single card gpu?]
http://www.sapphiretech.com/presentation/product/?cid=1&gid=3&sgid=1227&pid=2022&psn=&lid=1&leg=0#

Also will my motherboard handle such a high end card?

My specs:
i5-4570
Asus b85m-g
G.Skill RipJawsX 2x4GB
Seasonic s12ii 620W
320+2tb hdd
asus dvd drive
HAF 912

Seems like its high to me too, but their site indeed states 750 watt PSU for single and 1000 watt for Crossfire. I personally would get a 750 Watt one though but I like to run big PSU's :toast:

nothing wrong with that seasonic psu you've got

True...that's a damn good PSU!

I have a ups that goes nuts if more than approx 600 watts is drawn from it. I have a pc with a 2600k @ 4.7ghz, 6TB of hdd in there, a gtx 680 and at one time i also had a 580 too purely for physx. Also attached to the ups is my 27" monitor and router etc. At no point did this 600 watt ups EVER protest with this pc loaded with any game such as metro or bf3. I now currently have two pc's attached and running together on the same ups. The one i just mentioned, minus the gtx580. The 580 is in the 2nd pc along with a Q9650 running on a rampage extreme, one ssd and a 1TB hdd, optical drive etc.
My point is, pc's don't draw nearly as much power as you would think and so long as you have a decent psu, such as corsair or seasonic, then it will deliver what it's rated at and you should be good to go.

keep the one. 500W should be enough, but a lot of lower end series increase the 5V wattage to increase their overall power (like corsair VS series, local brands)

since Sapphire doesnt want a a blown PSU on their blame list they went with the 750 W

Your PSU is more than enough and since your motherboard has a 16x pci-e slot it will handle any card.
