Recently got some parts for a new build, one of which was a new PSU. I got a Thermaltake Toughpower Grand RGB 750W. Out of the short time I've been using the upgraded PC (about 2 days) I haven't seen the fan spin once whether it be on boot or through a load. The RGB fan hasn't lit up once either. Sounds like an issue to me but thought i should ask if anyone knew about it. Cheers.
