I just had a quick question regarding my Meanwell PSU. If I have a sp320-12 does this mean that I cannot exceed the 320 watts that this psu is rated at? In other words, running 2x200 watt tec's would cause troubles? I just ask because I am looking at getting better tec's than I currently have and am wondering if I should get a separate psu for each tec? Thanks in advance!!
