Do these FSP PSUs have a 20+4 pin connector?

I am currently completing a technical evaluation and would appreciate your assistance in confirming a specific detail regarding the following ATX power supply units:

FSP500-50ANB
FSP400M-70PD

Could you please confirm whether the 24-pin ATX motherboard power connector on each of these units is a separable 20+4 pin configuration (suitable for use with older 20-pin motherboards), or if it is a fixed 24-pin connector?

Hello,

From what I see on the data sheets they are straight 24 pin connectors.

I see, thank you
