Hello, I had this idea of upgrading my GPU. Currently I am running a Ati HD 5670 which is not sufficient anymore for the latest games. I thought of upgrading to an Asus DCUII Top Amd R9 280x. Because it has a really good price to performance ratio in my country. It costs about 230 eur. And it should be able to run the newer games for a while. so i think it is pretty future proof. But i have one issue though, i only have a 500W power supply which is 80 plus bronze. The cpu i run at is an Intel I5 760 which consumes 95W and slightly overclocked. I am running also 3 HDDs one at 7200 rpm and two at 5400. I also am running a CM seidon I20M. and also 4 chassis fans. I am not sure whether my PSU will be enough since i might overclock it slightly. I do not want to burn out my PCIE slot or PSU.

your psu is an quality one from seasonic, has the cables needed (1x6pin + 1x2+6pin) and with combined 12v rail of 34A it is sufficient for your setup. go easy on overclocking though

After a bit of Googling it turns out that PSU is made by Seasonic (= the best or at least damn close to it) so you should be fine.

Thanks for the info. i still might consider it though. the PSUs are not that expensive, but i just do not want to recable my whole system :D

So i guess ill start with that, and after a while if i feel like it i might upgrade to something like an corsair RM750 or so. just to have the room for some sweet overclocking :) oh, btw will i have to use some certain cables or just plug in the 6 pin and 8 pin, becasue i know that some PSUs with more 6 or 8 pins have different Ampers on each. But i think i only have the 6 and 8 pin though

i would avoid the cx - rm from corsair. i would prefer a 650w, would be more than enough for any single gpu configuration and o/c as much as you want.honestly, even a 550w would easily suffice

Oh ok, thanks :D but maybe after a few years like 2 or so i might put it up in CrossFireX. so there i would need that 750W or more PSU, but for now ill hang on to this. oh and i figured i have 2x 6 pin and one 8 pin. Does it matter which ones i plug in? or it doesnt matter which one of the 2 6 pins i plug in?

in the computer world, 2 years is a lot of time,bottleneck issues will quickly emerge,as your cpu is getting rather old. if i would be orclocking on your current system i would the cpu to keep up pace with 280x!

The Cpu is already Oced and i would oveclock it further if i were to add another GPU. or by that time i might aswell build a new rig.
