Kingwin Lazer Platinum Power supplies have features and safety options that one needs to have a good, stable and reliable system. Many of these feature and safety precautions can be taking for granted when dealing with a good name brand unit. One of the units we would put into this category is the Kingwin Lazer Platinum 750, which we are reviewing here today.

Introduction to the Kingwin Lazer Platinum LZP-750 Power Supply

If you really pay attention to the PC DIY community you will find that there are just as many power supplies being pushed out on the market than just about any other component. We are just so many to decide from for those considering themselves builders and enthusiasts.

And for the not-so-well-informed buyer power supplies are the one component you don’t want to take lightly. You don’t want to have your rig and out for the count because you didn’t want to spend a few extra bucks on a better power supply. Getting a 800 watt power supply for $30 is not a good buy.

Closer look

To begin with this particular model is Platinum certified by 80PLUS approving authorities. This is the highest efficient level a power supply can achieve. And with such a certification, you are in for a better all-around running system with better operation when the system has a load and a better looking electricity bill at the end of the month.

According to Kingwin the 750W Lazer Platinum has a rating of 92%, 90% and 89% efficiency at 50%, 20% and 100% loads. These are the minimum numbers to obtain the Platinum status from 80PLUS.

The Lazer Platinum uses a large 140mm cooling fan with a maximum dBA rating of 24 to keep the internal components in the ideal cold environment. The fan is PWM controlled meaning that heat and load will determine how fast the fan will spin.  The ECO Intelligent Thermal Control System will allow the fan to spin only when necessary or not at all.

The permanent cable attachments are the ones that are commonly used which would include the main ATX with EPS plugs and dual PCIe connectors.

Here we have the rear section or cable section of the power supply. There are a total of eight plugs which Kingwin call Crystal Cubes for each of the cables that come with the unit. The connections are totally unique from others we have seen. And what else is a little different is the fact all the connections are the same, so it doesn’t matter each connector you plug into regardless of the extension.

We found many companies are starting to place the product sticker on the top of the PSU and it applies to the Lazer Platinum. It makes for a nicer and much cleaner look especially when looking at the inside of the system from an open side panel. We see the unit has a maximum of 62A on the single 12 volt rail.

The side panels consist of a sticker with the Lazer Platinum logo on it. I would guess being a sticker would keep the cost at a more reasonable level. And it can be removed if not wanted.

Here we have the cables themselves. They are carried in a black rubber solution making them flat and flexible.

Results

We know that testing a power supply on a loaded system is not the very best way to do so, but you cannot overlook real world testing. Other sites have methods that use thousands of dollars in equipment to provide them greater detail. We have a trusty digital multimeter. Those sites and the methods they use should be the true means of determining how good a power supply really is; however, we feel that showing you how it performs under real world conditions is also a valid measure of its performance.


Conclusion

Electing a high powered power supply to run your system is no easy task. So, we will try and make it easy for you. Go to your favorite PC parts store and tell them you want to pick up a Kingwin Lazer Platinum unit. In our simple test we find the unit to be pretty stable and quiet. These are two of the most wanted aspects of a power supply. The third would probably be price. The 750W version of the Lazer Platinum comes in at about $179. Not too bad of a price for a good Platinum rated unit.
