Hello all,
I'm planning on doing a completely new build soon and today got my hands on a wattmeter, a nifty little device whereby it shows the instantaneous wattage going from the wall socket to whatever is plugged into it. So I decided to see just how much wattage my computer was using (i'd always been curious).
Now, it is to my understanding that a power supply only draws the amount of wattage the computer needs at any given time.
Here are my systems specs, as you can see, getting on a bit nowadays:
Intel Core 2 Duo E6700 (2.6GHz)
GeForce GTX 280
4 sticks of 1GB ram
2 traditional SATA hard drives
I have a 800W PSU in this thing.
Upon booting to the desktop the wattmeter recorded that I was pulling 130W. I decided to run Future Mark Vantage to strain the system (and it did), yet the wattmeter recorded that I was only pulling about 300W under load.
Surely something gives, I knew at the time I built the system that 800W was a bit of an oversight, but back then the GTX 280 was the most powerful card out and I wanted to play it safe.
But given that I'm only pulling less than half that wattage, is it true I could have well bought say a 400W PSU?
Thank you for your time!
