Will lowering the clock on a graphics card decrease power consumption?

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

If i were you, i would stick t integrated graphics for now. 500w is nowhere near enough for a dual gpu setup.

There are 500w PSU that could support certain dual gpu setups.

Since so many power supplies are inaccurately labeled for power output, it would be helpful to know the brand and model number of your existing PSU.

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.

I'm not optimistic. I was able to find very little on that model, which is usually a bad sign.
