power supply cables question

[CD307]

Hello everyone, i have a quick question I was hoping someone here could answer.
Yesterday my wife picked up a new case, a NZXT H440. So i started moving her hardware over into it from the stock Asus case she had before.
Everything went well until it came to hooking up the power supply, and I noticed that the 8pin 12v cable cant reach the motherboard. Its a lower end power supply with all the cables attached directly to the inside of the power supply, so the cables cant be easily replaced.
So my question is, is it possible to find extensions that I can use to extend her current cable or does she need a new power supply all together?
This is an issue Im also going to run into in a couple weeks, as I have ordered an obsidian 900d and will be hooking it up in a couple weeks when it arrives
at my local computer store.

Any help will be greatly appreciated!
Thanks in advance.
