If you are planning on hiding the PSU Cables using the Antec 1200 cable mamagement case system. Then yes you will need one. But if you do not mind the PSU 8-pin Mobo power cable running across the length (Bottom to Top) the no if cable length is 11" long.
You will also need this 8-pin Power Extension cable. It is needed on most Bottom mounted Psu cases. 1ST PC CORP. 12" 8-pin EPS extension cable Model CB-8M-8F - Retail $7.99
