Yes, but personally i would just buy another powersupply.
Sounds abit silly i suspect however if your powersupply is Generic and has already run out of power connectors i’d just go out and buy a cheap Generic NEW powersupply.
www.ebuyer.co.uk - search for 600W - it’s a Generic PSU and is £18 LOL! - be more than enough for your 3 year old system, as a splitter is going to cost you around £9 or something stupid.

I agree with Procal. If your powersupply doesn’t even have enough to add the second HDD, then it probably sucks pretty bad. I’d just go with a new, cheap psu.
