Techniques pertaining to powering multiple platforms with a minimum impact on air passage in a predefined environment are disclosed. Instead of connecting each of the platforms in a chassis to a power supply therein, embodiments of the present invention uses what is referred to as cascading powering to power all platforms within minimum cable delivery. According to one embodiment of the present invention, a motherboard is disposed between two power supply units that are used to power the motherboard. The motherboard has power connectors located towards or near the power supply units so that only short cables are needed to power the platform.
