Okay, so I installed some stuff. Like a lot. I'm thinking this is a power problem, but not sure. Out of 3 Speeze LED fans, two are tealish in color. Not sure if this is power or just crappy LEDs. Out of 4 Thermaltake CCFLs, two don't work. At all. The Nexus fan controller's LEDs light up, but knobs don't do anything. So I ponder if it's power or not. On Antec TruePower 550W: Power#1: DVDRW->DVDROM->HDD Power#2: CPU HS/F->ATI RADEON 9800XT Power#3: 4 CCFLs->2 Fans->Fan Control Power#4(FAN ONLY): 3 Fans.
Take everything out, then plug a few things in at a time and test as you go, should have been the way you did it to start with tbh. 'doc
I am running alot more than that on a antec 430( I think ) There might be some sort of a rail prob, or ....... are there dedicated fan lines on that psu, cause on mine, if I used those on anything but fans they just wouldnt work
