Kingwin Lazer Platinum 550W Power Supply Review

Installation & Testing:
Now I hadn’t installed a Power Supply in sometime, so I was a bit anxious as to whether or not putting the thing in would go swimmingly. It did – Kingwin makes installation very straightforward, and I only had to plug in the harddrive’s modular cable to get my PC working right off the back. The cables are long enough so that I could easily plug everything in without much fuss.

The results we got were very good, with the biggest ripple being 1.43% on the 3.3V, which is well within the 5% threshold we look for. The 12V was the most stable with only a .72% ripple.
