Hi all :)

 

This is old question and look like noob .. but i need to confirm from corsair and corsair users :).

 

My rig spend ~450W (i7 4790k - asus strix 980ti .. 7 fans 3hdd). I want to ask if i use Ax1200 i will pay double electronic's bill with RM650 both is 80plus Gold classs.

 

Few users said .. the psu draws as much power as it needs, so i wont be pay for extra. Meaning my pc need 450~, psu draws about 500-500W when i use AX1200 ?

 

Regards

PSU only puts out whatever the demand is. Doesn't matter if you use a 500W or 1500W.

 

What may vary is how much power it draws from the wall since efficiency varies across different loads, but you're only talking about a 1 to 2% difference when both PSUs are Gold rated.
