Review: No Problems - Haven't had any problems with the FSP power supply so far. I build small Mini-ITX builds for my military pals (or whoever). When you are moving a lot, having a smaller form factor PC is really nice. The only thing I recommend is to purchase an 8Pin to 4+4Pin cpu power cable, the FSP comes with only an 8Pin, but that's not a negative, just be sure to check what your motherboard needs. The FSP power supply doesn't have an off/on switch, so be doubly sure you are powered off and unplugged when you want to reach inside your tower.
Review: It is really loud. - This is one of the cheaper flex psu for a good reason, it is really loud. The power supply fired up in good working condition, but I noticed a loud noise coming from my computer. I just swapped it out it a silverstone psu which hardly made any noise. When I installed this one it made a huge difference in ambient noise. I thought it was the Gpu fan, but it was at idle, my cpu heatsink fan is quiet too. But I put my ear next to the psu exhaust and clearly could pinpoint it. So first impressions is that it is cheap and works well. Con is that it is really loud.

I have used fsp power supplies for over 10 years and in my opinion one of the most reliable especially when used in diy applications or replacing old tired inefficient oem power supplies.
