1. A data center comprising:
N computing devices; and
T power modules, wherein each power module in the T power modules comprises a first power device and a bus; the bus comprises a first electrical connection end, N intermediate ends, and a second electrical connection end; the first electrical connection end is connected to the first power device; the N intermediate ends are respectively connected to the N computing devices; a plug-in node is disposed between an (I−1)th intermediate end and an Ith intermediate end of the N intermediate ends; and the plug-in node divides the bus into a first subline and a second subline, wherein T is a positive integer, N and I are positive integers greater than or equal to 2, and it is satisfied that I<N; and
for at least one power module in the T power modules:
before the data center is expanded, the plug-in node of the at least one power module communicates the first subline with the second subline, and the second electrical connection end of the at least one power module is idle; and
after the data center is expanded, the plug-in node of the at least one power module disconnects the first subline and the second subline, and the second electrical connection end of the at least one power module is connected to a second power device for expansion.
