Bugger. Time to buy another then I guess.

Thank you. Tried my PC's PSU, now I have a spinning pump but still no screen and now no lit up RGB ring as well ..

Yup everything is seated correctly. Like I say, the RGB ring lights up red but there's no other signs of life. It is external and powered by a phobya molex PSU. Its wattage rating should exceed the power draw of the pump and three fans I intended to use (Inc start up power draw).

Hi all, just finished my new build with remote rad and d5 next pump/Res however on the first power up it's giving me nothing other than red lighting. The pump won't turn and the screen isn't working. Any ideas? Thank you in advance.
