A:AnswerIt has a 300 watt power supply. I have several clients that let them run 24/7 and have no issues. If you are planning on putting a higher end video card in (say, for gaming,) you would most likely need to put in a higher rated power supply. I would note that if you are planning to put in an a higher priced video card, you might want to make sure to get the I3847 with the i5 processor instead of the lower end i3 processor.
