Today we have the opportunity to have a look at a power supply being branded by KWI Technology Inc., or better known to most readers as Kingwin. Kingwin has been in business since 1992 manufacturing mobile racks and general storage solutions. Today though we find Kingwin branding, and in some product categories developing, a number of different components and peripherals including cases, CPU coolers, liquid cooling systems, and power supplies in addition to its core business markets. Today’s Kingwin offering is from another extension of its Lazer branding; the "Lazer Platinum." In particular, we will be reviewing the Lazer Platinum 550W (LZP-550) which is developed in conjunction with SuperFlower once more.
SuperFlower Computer Inc is a name that may not be familiar to most of our US readers, but as a company SuperFlower has been designing and producing power supplies, and chassis, since 1991. In 2006, it expanded with the establishment of a new subsidiary factory, Jing Hua Co., Ltd, now handling its increased power supply production. While SuperFlower has not been a high profile OEM in the US, some of its products can be found branded by TTGI, MadDog Media, Kingwin, and occasionally under it own "SuperFlower" brand. One of the distinguishing points spearheaded by SuperFlower units was the inclusion of some of the first 140mm fans, and while normally not found as the OEM behind "ultra high end brands," SuperFlower has typically made solid budget oriented offerings.
The Kingwin LZP-550 is the 4th power supply we have seen from Kingwin and is the smallest by capacity at just 550W. In addition to being the smallest capacity unit we have seen from Kingwin, the unit's Platinum branding gives us another clue on how this unit differs from other Kingwin Lazer products that we have reviewed before. This is not only the first 80Plus Platinum advertised unit we have reviewed from Kingwin, but the first 80Plus Platinum unit we have seen. To be sure though, efficiency is not the be all and end of all of a quality power supply. In addition to that obvious advertised advance, what else does Kingwin have up its sleeve with this new unit?

This time around we find the Lazer webpage just has a list of features and no real advertising or copy for the LZP-550. We do not consider this a bad thing either, as most of the PSU marketing it more story telling than product description. Moving on let’s see what we can expect when a user purchases the Kingwin LZP-550 supply in retail in terms of documentation, accessories, cable count, rail layout, output characteristics, and general build quality.
