cause i wanna make my gameplay hd, but when the hdmi cable is in, there not enough space for the power brick cable,
Seeing as the power cable gives the system the power it needs to run, no, you can't play without it. However, you are able to play with both the power cable AND the HDMI cord. There's enogh space for both to fit into the console, and the power cord plugs into a wall outlet while the HDMI cord plugs into your TV's HDMI slot. There shouldn't be any problem with room.
