Confirm the exact supply and installation scope
Request written confirmation of the exact model and condition, PSU, cables and accessories, supply voltage and circuit requirements, cooling interfaces, stock or lead time, delivery charges, taxes and warranty coverage. Catalog specifications do not confirm the contents or condition of an individual shipment. Have a qualified installer check the electrical circuit and heat rejection before connecting an ASIC.
