A Power Supply Lies Before You!
The number on the box (often in the title) indicates the wattage of the PSU. When upgrading parts in the future, keep note of the amount of power that they consume.
In a dimly lit room lies an ancient source of power: a power supply. Locate and take the PSU out of its packaging (marked H) and take note of the contents in the box.
D. Slide in the PSU with Fan Facing Down
With the fan facing downwards, slide in the power supply from the side opening of your H510 case.
E. Secure the PSU
Press the PSU against the rear of the PC and screw it into the case using four 6-32 Hexagon screws that came with the PSU (also in the white box from the H510 case).
