Do you currently have password-based SSH access to the server? if so you can just copy from puttygen to the Windows clipboard, then right-click-paste it into the file over the existing connection - either by editing the authorized_keys file in nano/vim or just appending using cat
Code:
cat >> ~/.ssh/authorized_keys
<right-click-paste>
<Ctrl-d>
Remember to copy the key from the frame in the puttygen window (where it says "Public key for pasting into an OpenSSH authorized_keys file") NOT by saving the key to file (which will be in putty format)
