Kingwin Lazer Platinum 850 W Power Supply Review

Conclusions

The Kingwin Lazer Platinum 850 W proved to be an excellent power supply, with efficiency between 89.5% and 91.9%, voltages closer to their nominal values than required (3% voltage regulation), and extremely low noise and ripple levels. It also comes with an excellent price tag for what it has to offer. Other 850 W power supplies with the 80 Plus Platinum certification, such as the Enermax Platimax 850 W, are 20% more expensive. In fact, the Lazer Platinum 850 W is available in the same price range of high-end 850 W power supplies with the 80 Plus Gold certification, such as the FSP Aurum Pro 850 W and the Corsair AX850W.

The only negative we saw with this power supply was its cable configuration. We think a high-end 850 W power supply with the 80 Plus Platinum certification deserved more SATA connectors and a total of six video card power cables, allowing you to install three high-end video cards without the need of adapters.

In summary, if you are thinking of buying a high-end 850 W power supply with the 80 Plus Gold certification, you may want to consider the Kingwin Lazer Platinum 850 W, which is in the same price range and offers higher efficiency. However, if the relatively low number of cables and connectors is an issue for you, you will have to pick a different product.
