Introduction

We would like to thank Kingwin for supplying the review sample.

This is the third Kingwin PSU that we have had the chance to evaluate. In the past we have reviewed the Kingwin Stryker Fanless 500W and the LZP-550, both platinum units that obtained an Editor's Choice from us. Today's review sample, the Lazer Platinum 1000W or LZP-1000, also features Platinum efficiency and it is made by Super Flower, Kingwin's favorite OEM which as it seems tries to knock Delta and Seasonic off their thrones. The LZP-1000 is the flagship of the Lazer Platinum series which includes five units with capacities ranging from 550W to 1000W. All are 80 Plus Platinum certified, as the name of the series implies and feature a semi-modular cabling system with the characteristic crystal cube connectors on the modular cables.

According to Kingwin, whose products currently are available only in the USA, the LZP-1000 incorporates the ECO Intelligent Thermal Control System which ensures that the cooling fan will run as quietly as possible and efficiently on the same time. Also the LZP-1000 has a small red switch on its front side, through which the user can select between two operation modes: Eco mode which is preselected and up to a certain internal temperature deactivates the fan and normal mode where the fan is always working and adjusts its speed automatically according to the PSU's internal temperature. Basically the main difference of the ECO mode compared to the normal one is that it practically converts the unit to fanless up to a certain load level/operating temperature. Some more details about the ECO Intelligent Thermal Control System can be found in the following illustration (courtesy of Kingwin).

Specifications

Efficiency is the highest possible, 80 Plus Platinum, and the unit can deliver its full power continuously up to 50°C. The available protections are few and only the basic ones are provided while the cooling fan uses ball bearings so its lifespan will be increased compared to a sleeve bearings one. The depth of the PSU is longer than average (160mm) something that partially is justified by the 1KW capacity, however there are units nowadays with even higher capacities and only 160mm depth. The weight is significant since large heatsinks are used in the internals, to allow the semi-fanless operation at lower loads. The warranty is sufficient at five years and the price is very good for a PSU with these characteristics. However in Europe the Super Flower Golden King 1000W, which in essence is exactly the same unit with different badges, can be found in an even lower price.


There is only one, powerful, +12V rail which can output the full unit's power, something very convenient in contemporary PC systems that heavily utilize +12V. The minor rails are restricted to 100W, however you are not going to need more power from these two rails. On the contrary we would like to see a stronger 5VSB rail, since 2.5A are the minimum allowed power for this rail nowadays.

Cables & Connectors, Power Distribution

The total provided PCIe connectors are six and they are available at the same time along with the two EPS connectors. Also the number of SATA and peripheral connectors is sufficient for the capacity of the unit. The length of the 24 pin ATX connector would be ideal with 50mm more while the modular PCIe cables are kind of short at only 500mm. We would like them to have at least 600mm length. The distance among the connectors, in cables that have more than one of course, is 20mm less than the 150mm of length that ATX spec recommends.
The fixed cables are fully sleeved and use thicker 16AWG wires for decreased voltage drops while the modular cables use flat ribbon wires of 18AWG size, something that will make cable management a breeze.

Since this PSU features a single +12V rail we do not have anything to comment about its power distribution.

Packaging

The packaging has a large footprint and on the front it features an illustration of the unit with all modular sockets occupied. Under the "Platinum" word, in the top right corner next to the grey stripe, resides the 80 Plus Platinum badge and right under it, on the bottom side, there is the badge for the five year warranty. As it is used, on the rear side of the box we find many more details about the unit's features while a reference to its specifications is given on one of the packaging's sides. Here we should note that on the rear side we noticed a reference to an LZP-1200 unit, so we should expect in the near future a new 1200W Platinum unit from Super Flower/Kingwin.
