02 · THE BOARD
Twelve places you need to know
Numbered like the labels on the 3D model. Click one and the camera flies to it.
03 · MISTAKES
Three ways to ruin this build
Each one is a real first-build classic. Here they cost nothing, so make them on purpose.
Step 02
Skip the thermal paste
Metal on metal looks flat but is full of microscopic air gaps, and air is an insulator. The chip runs to its 95 °C limit in seconds.
Step 04
RAM side by side
Two sticks in A1 + A2 share one memory channel. The PC boots and nothing warns you. It is just slower, forever.
Step 07
Forget the GPU cable
The slot alone gives a graphics card 75 W. This one needs about 220 W. Fans spin, lights glow, the screen stays black.
