Hi guys,

I'm pretty new to pc building and modding and I can't seem to troubleshoot getting these uv ccfl bulbs! I contacted the supplier for help and he was a huge dick.

So here's the scoop: I have 2 uv ccfls that are connected to an inverter and have molex power (both a male and female split).

My psu is an evga 750w GS fully modular. No molex. Came with a molex (2) to 6 pin adapter. Tried multiple slots in the 6 pin. No worky.

Anyone got any suggestions? I think I'm not getting enough juice to the bulbs. Bulbs seem fine from what I can see but the inverter could be poop.

Help! Please and thanks

PCI-E supplies only 12V while molex supplies 12V and 5V. Rather than powering your lights off from PCI-E, power them off from SATA with this adapter,
amazon: https://www.amazon.com/15-Pin-Female-Splitter-Manhattan-308977/dp/B002LBROAA

SATA has 3.3V, 5V and 12V in it while 5V and 12V are supplied to the molex connector.

Though, when your UV bulbs need 12V then what's the point of the inverter? Inverter is used when the voltage needs to be changed, e.g 12V is supplied and UV bulbs need 8V. Or when your UV bulbs use AC power since PSU outputs DC power.

Are there any product page or part number of your UV bulbs so that i can search it's specs from the net?

Edit: CPU power connector, commonly known as EPS has 12V and ground wires...

I believe the lights need 12V. I tried the included molex that was split (2 male molex) on one end and 6 pin on the other and that didn't work.

Not sure if this is a dumb question since I don't know this stuff very well. But could I get a molex to 8 pin adapter (vs the included 6pin) and plug it into the empty "CPU 2" plug? Does that fuck anything up?

Edit: CPU power connector, commonly known as EPS has 12V and ground wires vice-versa compared to the PCI-E connector. If you plug your adapter to EPS connector, you'll fry the inverter and/or UV bulbs since you'd be supplying 12V current directly to the ground wires.

Here are PSU power connectors and their pinouts listed if you're interested,

The uv ccfl bulbs are from dazmode. I'd link the model but the owner was a real dick and banned me. I asked him for help and he sent a message explaining what a bulb was and basically said I was an idiot. I said he was really rude and then he banned me from his site. Nice guy yeesh!

They're just like these ones though:

You can try to use SATA to molex adapter and see if it helps.

You said that you're not getting enough juice to the bulbs, do your PC internals have UV reactive components in it or not? E.g UV reactive custom made water cooling tubing or liquid. If not, there's not much component glow to be expected from UV lights.
