Re: Mega Watt S700-12 50 Watt AMP

Yes I have this supply and it is the main workhorse in my base station. At first the fan noise didn't seem that bad but after about fifteen minutes it started to get under my skin. However, now that it's inside my base station I can barely hear it. Nearing the end of my base station build and throug...

If you can, stick as close to 100% and you shouldn't have any problems. If you are...
