I looked at the power supply, the color is grey so and the back of it isnt powder coated (its not blacked out), but I can find a model number or figure out what the brand is. I usually use the computer for 1-4 hours a day depending on what day it is. On the weekend, I use it up to 4 hours and on the weekdays usually no more than 1 1/2 hours. Based on what cables other power supplies have, I'm assuming it is somewhere around the 300 watt range. A few weeks ago, I plugged a fan cable in, and the computer wouldn't turn on. When I unplugged it, it would turn on. I said when I replace it because im learning how to use photoshop, edit videos, and program and I dont feel as my computer can handle these programs. The computer parts are very good; I have a gtx 1050 low profile card, i5 760, 8gb of ddr3, a 240 gb ssd, and windows 10. Please let me know if I should provide any more info, and I would greatly appreciate if you helped me more, thanks
