Supermicro 1027gr-trf power consumption

Does anyone know what kind of power these draw? I got a free barebones one and want to know if it's going to be worth investing in it or if power consumption will make it not worth investing in. I'll likely be putting in 1 quad core e5 and ~16gb of ram with 2 1tb 2.5 wd reds and 2 500gb safe.
