I just want to know how much power my computer is consuming roughly. These are my specs:

AMD phenom ii 720 @ 3.2Ghz (95 watts)
XFX GTS 250 (150 watts)
Corsair DDR2 PC6400 800Mhz 4GB 1.8v
2 x 92mm fans
1x 120mm fan

I'm guessing that it's 95 + 150 + 100 = 345. Or would the ram and other components draw less power then 100 watts.

I have a 500 watt cooler master silent pro psu.

I'm wondering if i get an ATI 5870 (188 watts) and if i overclock my phenom ii 720 to 3.4ghz whether the psu would be able to take it.
Not that i would leave the cpu clocked to 3.4ghz permanently just that i would do it for a one off time, and for the crack of it.

But my main question is how much power consumption is my pc configuration is currently using.

Thanks in advance.

lmao that is soo wrong, it said i need a 739 watt psu minimum for my current configuration. What does it want you to put in when it says Capacitor Aging and cold cathodes. i entered nothing for that. I'm not kidding i entered everything in correctly i didn't put dual graqphics cards etc.

the cathodes are uv lights?

Well, AMD recommends atleast a 500W psu with 2 6-pin connectors.
But your psu should be able to handle the system with a mild cpu overclock.

would that include a little voltage increase? I don't plan on going ahead over 3.4ghz. I have had 3.4ghz run with 1.45v from 1.35v before but i had a Tt 600watt toughpower since then. What do you rekon, and gpu overclocking, perhaps i am best to go for an ATI 5850, would give me guaranteed system stability and a bit of gpu and cpu oc? I wonder how 5850 overclock anyway would someone say they oc better for how much they can improve compared with 5870?

The power supply calculator gives a reccomended psu wattage, it doesn't tell you what the actual power consumption of the system will be.
There are footnotes at the bottom that explain capacitor aging and yes cathodes are uv lights.
You would have had to input much, much more than you've specified in order to come up with a 739 watt reccomendation.

Yes, even a slight voltage overclock shouldn't matter. At any case, the psu'l easily handle a 3.3 Ghz OC.
Going with the 5850 will undoubtedly decrease system power consumption. Also the 5850 is a good overclocker, & can almost match the 5870, when OCd. WIth that in mind, maybe, your system could even exceed 3.4 Ghz, with a stock 5850, or could run stably at 3.3-3.4 with an OCd 5850.

lol absolutely no chance for Nvida then. Is there any hope that they will produce a gpu that around 150 watts with good performance roughly equal to or more than a gtx 285.

so they're probably going to bring something out better than a GTX 480 but probably give it a power requirment of 300watts, instead or probably bringing out something more cleaner at least since they are already hanging on to best single fastest gpu anyway? Silly. They're not going to try to appear to the mainstream by at least making something about as fast as a GTX 470 and having it a bit more energy efficient. You've got to be kidding me you mean no more under 200watt graphic cards from Nvidia?

ATI is clearly better than Nvidia, regarding performance, their cards are smaller and less energy consuming, they aught to with the same wattage and same size of an nvidia card and easilly be able to produce the most graphical performance. I'm guessing a GTX 470 is about as good as an ATI 5870 which is 6 months out of date anyway, uses 188watts compared to 215?

500W PSU should be ok, the 5850 recommends 500W for single card, 750W for crossfire. The 5870 is a little more demanding, but I think you can get away with 500W, but it'll be pushed. After that your next upgrade should definitely be a 750W or higher PSU.

for one 5850!! A GTS 250 runs on 150 watt requirement, 5850 - 151, the GTS 250 asks for a 450 watt minimum psu. I have a 95 watt cpu and will stay on 95 watts as well, as my mobo supports up to 95 watts. 500 watts should be plenty, it should in my opinion be enough to power up to a 190 watt graphics card. So i want to know whether someone would agree with me to on that, obviously a 190watt tdp gpu will not go with overclocking.
