I am going to build a pc without a graphics card because I am going to wait for the perfect one for me and I will be fine with Intel core i5 4690ks hd 4600. I think my system runs about maybe 100~300 watts, I am going to buy a seasonic x-1250. It's 1250 watts and my question is: will this hurt my pc and will is take/use so much wattage?
not bad for pc. bad for psu and power bill.
ive seen videos on youtube and what they say is you should use 60 percent or over of what the wattage output is on the power supply. this is for efficiency reasons. You will only use about 15 percent of that 1250w so it will be very inefficient no matter the efficiency rating. However, 1250w may be a futureproof upgrade to your current pc.
All im saying is with your current rig you will draw more power out of the wall with a 1250w power supply than say a Antec VP-450.
