Where Delta Electronics sits in the stack
Delta Electronics's placements in this catalog cover 18 parts, from layer 3 (networking & interconnect) to layer 9 (building shell, site & construction). None of them currently carries a sourced supply constraint tag. Across these parts it overlaps with other companies most often on the lines below.
What these parts are
- Switch systems & white-box ODMs — The physical switches — built by branded vendors and white-box ODMs — that house scale-out switch ASICs and connect racks into a cluster fabric.
- Board-level power: VRMs, power stages, PoL, power semis — The voltage regulator modules and point-of-load converters that step rack-level DC power down to the precise, high-current voltages each GPU and chip needs at the board.
- Power shelves & PSUs — The rack-mounted power shelves that convert facility AC or DC input into the regulated rail distributed to trays across the rack, built to the Open Rack V3 33 kW-class spec used in rack-scale AI systems.
- Fans — The axial and centrifugal fans mounted in server chassis and rack trays that move air across heatsinks and boards, still needed even in racks that use liquid cooling for the highest-power chips.
- In-rack busbar & power whips — The high-current busbar and cabling that carries power from the rack's power shelves to each tray, including Nvidia's specified ±48 V / 1,400 A busbar used in rack-scale liquid-cooled systems.
- and 13 more in the table above.
