PSC 7C20 covers hardware, software, and other equipment for tiered or enterprise data center facilities that house and protect critical IT equipment. The manual splits this from 7C21, which covers non-tiered facilities such as computer rooms and main distribution frame and telecom closets, along with the racks, cabling, and management systems inside them. That distinction, tiered facility against everything else, is the whole boundary. FY2025 obligations for 7C20 were $747 million.
Reseller-led, as usual for products
541519, Other Computer Related Services, took $340 million, about 46 percent. Electronic Computer Manufacturing (334111) took $228 million, Telephone Apparatus Manufacturing (334210) took $72 million, Computer Systems Design Services (541512) took $39 million, and software publishers 511210 took $31 million. The pattern holds across the entire 7 series: agencies buy IT products through solution providers, and manufacturer registrations sit second.
The two-code system in a sentence
The PSC names the purchase and the NAICS code names the seller's industry, which is why manufacturer codes rarely lead a product PSC.
Selling into data centers means tracking four codes at once: 7C20 and 7C21 for the equipment, DC01 for the support labor, and DC10 when the agency buys the whole facility as a service instead.
