Power usage meter?

[Zerk]

Hay good friends! Its me again.

I just posted a topic on 9800GTX+ SLI.

Now I'm wondering about Power.

Is there a Program that I can use to see how much Power/Watts/Amps I'm using? Besides one you buy and plug into.

If you ever saw a trubritar Video on YouTube.com you'll see in some he has a Watt meter in the Upper right corner,Is there a way I can get that?

Goal,I would like to see how much power i'm using now to see if I have the power to go SLI.

I have a XIGMATEK NRP-MC751 750Watt PSU with 4 - 18Amp Rails ,, link ,, http://www.xigmatek.com/product/power-nrpmc751.php ..

I looked at SLIZone.com to check the power supply's that will work, 9800GTX SLI didn't have my PSU, But it had 600W's and even 550W PSU's.

So is 36A not enough? or the total of 72A on 4 Rails?

Or did Nvidia just not think about the NRP-MC751 or forget it or something? I know they don't have all the PSU's there.

Anyway!

I thank anyone Vary much for any Comments!

Thank you!

OK

I have bean looking.

Says 9800 GTX 512 MB SLI Load-419W Idle-168W

Also it says:

A second GeForce 9800 GTX installed is another ballgame though; on this system it requires you to have a 750 Watt power supply unit at minimum if you use it in a high-end system. That power supply needs to have (in total) at least 45 Amps available on the 12 volts rails.

I have 72A on all 4 Rails at 18A each, Right?

So am I good?

Also.

have a wattage monitor keeping a close eye on power consumption during our entire test-session. This device will register the maximum wattage pulled from the wall power outlet. You are not looking at the power consumption of the graphics card, but the consumption of the entire PC. We had a total system wattage peak at roughly 420 Watts with two 9800 GTX cards installed, which is quite a lot.

So that mean I need a Wall outlet right?

Ahh.

Check this out.

My PSU is 87% Efficient

Now At guru3d.com I found a PSU almost Exactly the same as mine.

They hooked up 2 GTX 295's in Quad SLI and a QX9770 OC'ed to 3.6GHz .

And at max load it hit 692W or so.

Here's a link.

Awesome stuff.

This surely means i can run 2 9800GTX KO's. with my E8400 or a Quad core.

Just posting for others.

Thank you guys !

I have 72A on all 4 Rails at 18A each, Right?

No. Each rail can put out a maximum of 18 amps. Total is 60 amps.

 

[Zerk]

Yes.

Thank you for correcting me.

I forgot to change that, You are correct.

Thank you!
