Gtx470@942v wattage/tdp help

post #1 of 3
Thread Starter 
Hi,
I was going to upgrade my 470 as sli would mean i need a new psu aswell which i could'nt afford but i had a brainwave!

Now i've just been playing with undervolting and so far i'm at 657mhz@942v, i'll be trying for much lower at stock speed later when i have more time.

Now if i can get that voltage down to 920v at 607mhz what would you think the tdp/wattage would be?

I have a ocz modxstream 700 watt that is a year old, i could allso undervolt my cpu to 1.35v for 3.8ghz.

Thanks for your help

I think a 700 watt PSU is enough for two 470s without worrying about undervolting/downclocking.


Maybe I'm wrong, I looked the PSU up and I have no idea if it could handle two 470s or not.

Anyways while you wait for someone less stupid to help you...

If that is at the wall, then I think you're fine.

Thanks for the info.
I've got it down to 607mhz@.920v and i lose around 6 fps from original oc of 728@1.012v which is stock volts.

Surely with a voltage of .920v the 470 now has a lower wattage than a radeon 4850?
