hello again! im thinking about overclocking my sapphire hd7850 2 GB OC ( which is already sitting at 920 Mhz ). i want to try and break 1 Ghz since its such a nice round number and i heard it would give me a 10% ish performance boost. now im running this card off the 525W powersupply that came with my aurora r2 nearly 4 years ago. do you guys think it would be safe to push this card to 1 Ghz? im gonna overclock from the AMD overdrive tab in catalyst control centre. would my power supply be enough. thanks in advance! :D  this is a great forum

7850's use very little power, so your PSU is probably fine. And, 1000mhz on the core is a foregone conclusion on almost any 7850. I'd venture to say you'll have 0 issues running the core at 1000mhz.

if you do not add voltage(which can not be done in MAD Catalyst), the power draw will barely increase.

To be honest STABILITY is more important than headroom on a PSU of that size when overclocking. But again this only really starts applying with voltage changes.

uh this might be a silly question but how do i know how much voltage my graphics card needs and how much voltage my psu provides?

Not a silly request at all...

First of all keep in mind that increasing voltages increases the risk of damaging you graphics card. BUT if you do in patiently and methodically, it can be minimized and managed easily.

Now, you need to use a program that allows you to change voltages. Sapphire Trixx can do this.
Also get GPU-Z for monitoring voltages and a separate program to monitor temp.(realtemp or HWmonitor is fine)

oh ok thanks i would have picked you as the solution but the guy above your post only joined the forum few days back. and since you already got overclocking veteran++ rank i thought it would be nice to give the little guy some points xD haha thanks man! :D

LOL don't stress, I have been around the block. Best Answer is not something I care about.

If you need any help on OCing further. Just ask.

Oh and heres a useful guide to OCing a GPU with voltages.http://www.youtube.com/watch?v=DPaQWdkd-Eg
