Does overclocking take more power - Page 2

post #11 of 16
Yes over clocking draws more power from a PSU. I wouldn't OC your rig until you get the new PSU. When you draw over 90% of power from a PSU you start 'ripple' from surging back into the components of your rig. So the back surge goes through CPU, motherboard, GPU, RAM etc. Ripple is your worst enemy as it damages your components. High amounts of ripple can fry other parts of your system or degrade them to fail earlier than it's normal life span. Hold off. Get your normal benchmarks if you like for the time being and write them down at stock settings. Then when you get your new PSU you can OC it and you yourself will see the difference in your FPS in both OC and normal.

Alway go in small increments when over clocking and keep a log of your stats, as you increase continue to keep records. Your going to see what the OC is gaining and it's easier for you to tell than someone else's results in a different system can advise you.

Once you hit the OC ceiling so to speak you will start to see artifacting and you'll know you've gone to far and need to back down. You can add a small voltage tweak to see if the artifacting will subside and if it does you can raise your clock again about 15mhz to see if you can push it further. If the artifacting doesn't subside then you know you hit the max and back off and you'll know how far you can OC your card. Careful adding voltage because that can fry your GPU. IF you don't know what your doing or what voltage tweak your GPU can handle then just OC it until you hit the ceiling and stop. You'll know you've reached your max OC without voltage tweak and trust me it's going to be good enough. I don't like adding voltage unless I'm doing a quick bench for fun but even then I tread lightly but I don't keep it 24/7 I go back to stock voltage.

Make sense? I'm on my way to work and I just typed this very quickly. LOL.

wow wow wow where did you see that? that's a lie corsair is easily one of the best PSU brand on the market, anyone who says otherwise is a liar. i would recommend a Corsair 650TX or 750TX (if you plan to add that second 5770 anytime soon). but your PSU is plenty for 1 5770.

Underrating is good - would you rather have them overrate their specs?

850 is overkill *looks at sig* frown.gif

OC's take more power, depending on how far you push your system, even if it had four 5770's, a 650w is enough.
