Will lowering the clock on a graphics card decrease power consumption?
Last response: in Components
if so, would it be by a great deal? I have a gtx 295, amd phenom ii 965 quad core, but only a 500watt power supply. from what i've heard, 500watt probably wouldn't be enough to power everything adequately, so I reduced my gpu's core, shader and memory clock to minimum. I currently don't have the cash to buy a decent power supply, so I don't want my current one dying on me any time soon.
Actually 500w PSU are enough for mostly everyone if it's from a decent brand.
I was running a G620 and a 4670 on a 300w power supply almost a decade old.
Lowering the clock might reduce power consumption however if you push the card hard on games/whatever you do a lower clock might actually use more power

There are PSU labeled "500 watts" that will blow up when you draw 250w, and some that will do 550w without breaking a sweat. Thats a pretty big spread.

That's (the system used for the shown graphs) with a 3.8ghz OC'd i7-920. That's a 130W CPU with a ~40%+ OC.
What PSU do you have exactly?
If it's not a generic you can pull it off.
