Re: wattage question

thats a good question... i always wondered how anandtech found out how they get their PC Power Consumption...

Re: wattage question

I thought they used whats effectively an amp meter, plugged that into the wall and then the computer into the meter, just a little more complex then your run 'o the mill one. At least that seems logical to me.

Re: wattage question

A 450w PSU is pushing it... but I suppose in theory it can handle it.
If I were you, I would shell out a bit for a nice 600w+ PSU.

Also, there are PSU calculators on the internet. Google wattage calculator or something. There are no programs that can monitor the power your computer is consuming. If anything, it'd have to be a piece of hardware.

Re: wattage question

this is what it says,dc output:=3.3v===22.0A(ORG),+5v===36.0A(red),+12v=== 18.0A(yel)=5vsb===2.0A(purp) and then it repeats the last one thre times, just diferent coulours, and finally fuse rating:8a,250v-(3.3v at +5v=220w max)

thats directly off teh side

Not necessarily, I'd say if there is 30+ Amps on the +12V rails, then it'll be good for the 8800GT. But to be on the safe side, looking towards for the Corsair 520HX or Xclio 500W/550W would be a good idea.

Re: wattage question

No, there isn't a software that can do that, TMK.

Wattage calculators are inaccurate, too.

Newegg.com - P3 Kill A Watt Electricity Load Meter and Monitor could be used

and you guys should know there is still more to a power supply than the amps on it's 12v rail.. it's definitely not the only thing you should be looking at.

Re: wattage question

Well some of us aren't that experienced to the other things in a PSU except for quality brands and AMPs.

*Me to be exact. But, my brain is still collecting info on Hardware Troubleshooting and such. :happy:
