  • “You got a 1kW PSU for your rig? Nah, just for the proc”

    I know these aren’t for home, but in the US/Japan/Canada/Mexico you’re gonna start seeing the need for dedicated breakers. A lot of apartments skimped and put in 10-15 amp breakers, which can (safely) support 960-1440 watts. A 20 amp breaker can do 1,900 watts at least, but again that’s usually for an entire room. Not just a single device.

    Edit: added a few more countries that use 110/120V to illustrate it’s not just a US issue.









  • The two red lines are at a right angle, you can connect them and solve for the hypotenuse using the normal a^2 + b^2.

    At this point you now have a second triangle that contains the X you want. Also, since the outer shape is a quarter-circle (assumed) you know that the corner in the bottom right is 90 degrees which makes the two side equal in length.

    Since it’s an equilateral triangle, and you know the hypotenuse, you can back it out with c^2 = 2a^2 and solve it that way.
