That's 750w at 12v. Big difference.shoot my gaming pc has a 750w power supply, 400 ain't enough to scratch your nuts over
Running a 400watt hid with 400cfm fan with filter and another fan blowing on plants. Is that to much for all bills paid in an apartment?
That's 750w at 12v. Big difference.
I'm pretty sure watts used is watts used, the power supply from my pc is going to pull 40-85% of that 750w's out of the wall to power my computer depending on what i do with it. a 400w light + a ballast is going to pull like 440 watts out of the wall. I'm not quite sure the volts have very much to do with it??? correct me if i'm wrong here
My understanding is that the PSU converts the power from 120 at the wall to 12v, 3.3v, 5v ect for the computer to function.
I may be wrong about the voltage. I did a quick calculation and at 12v, 750w would be 62.5 Amps. Clearly beyond the capacity of household electrical outlets. So i was wrong. I guess I have to give back my "expert" card.I'm pretty sure watts used is watts used, the power supply from my pc is going to pull 40-85% of that 750w's out of the wall to power my computer depending on what i do with it. a 400w light + a ballast is going to pull like 440 watts out of the wall.

Yes, but the rating is on the maximum number of amps that can be pulled by the PSU before it is converted/stepped down.
What most people don't realize though, that a 750w PSU, that's MAX the unit can draw. Most home computers don't have an array of 12 spinning hard disks, and are in fact never using nearly *close* to that rating.
I assure anyone here that a home computer, even a home server isn't going to be using as much energy as your 400w HID, unless the HID is in lights-off.

Exactly, the two can't even be compared....Yes, but the rating is on the maximum number of amps that can be pulled by the PSU before it is converted/stepped down.

Some of those "smart" meters can record data precise enough that they can determine what type of appliances are running.
