is it the right sentence, i want to write an email to my server vendor.

1-"please make sure that the power supply you will send be compatible with our installed server machine"
2- " please make sure that the power supply you send be compatible with our installed server"

which one is correct or both are wrong :).

Please make sure that the power supply you send IS compatible with our installed server.

its a future tense why cant i write.
" please make sure that the power supply you send be compatible with our installed server"
