Totaly true. Many weird cables were attached to the motherboard that didnt fit in to my new build. Looked for some sources, some said it would be ok, so i took the chance. Well just got to buy a new one nowMake/model of prebuilts, especially 3rd party vendors such as Dell, Lenovo, Sony, HP etc basically require an exact swap since windows is tied to the specific motherboard as is other integrated software and such things as power or case switch connectors. Swapping out for an aftermarket motherboard may seem easier, but often opens up a can of worms most aren't ready or able to circumvent.
HP Omen 880-138. Tampa 2 motherboard.What was the make/model of the prebuilt?
Some used proprietary motherboards.
To avoid reactivation issues, a exact replacement is easier.
It also seems strange to have a 1200w psu in such a pc.
Was there a reason for that?
