Kingwin is back with some more Platinum efficiency love but with much more power and a little extra something.

The new Kingwin Lazer Platinum 1000W unit offers excellent efficiency, modular connectivity, quiet cooling and lots of power.

Kingwin has yet to do anything but impress us in the past and we expect no less from their latest unit, the LZP-1000. Let's take a close look at it right now.

Specifications, Availability and Pricing

Just as we saw with the Enermax Platimax 1000W unit, the Kingwin LZP-1000 unit is only rated for 20A on both the 5V and 3.3V rails. It also has a single 83A 12V rail capable of 996W of power. A little bump up on the minor rails would be nice.

Kingwin makes sure you're taken care of with plenty of features in the LZP-1000. All your protections are present. The LZP-1000 has both native and modular cabling, all of which is fully sleeved. The LZP-1000 is also capable of delivering 100% continuous output at 50C.

Kingwin has an MSRP of $229 on the LZP-1000 1000W unit. We were able to find it cheapest at Newegg for $193.98 at the time of writing this article after shipping and a $20 MIR. That makes it at least $50 cheaper than any other 1000W Platinum unit on the market today. Kingwin backs the LZP-1000 with their customary five year warranty.

The Packaging

Kingwin uses the same design on the packaging that we saw with the LZP-550, albeit in a different box.

The back has quite a bit of information on it. Perhaps they don't stress enough that the unit has selectable fan modes (as indicated by the graph) so that the unit can operate fanless until it gets too hot. The unit will stay fanless until it nears 70C in temp. Once this happens, active cooling kicks in until the unit reaches about 50C and then turns off again.

No useful information on the top of the box.

Or the bottom...

One side lets us know it has "Crystal Cube Connectors." It's just a fancy name for modular connectors.

Finally, some specifications on the other side.

Inside the Box

Things are packed really well with foam all around the unit except for the front and back sides. It has the modular and native cables to protect it on those sides if needed.

The I/O specification label can be found on the top of the unit.

The Lazer Platinum logo can be found on one side of the power supply.

The other side only contains the serial number.

On the back we can clearly see something a little extra beyond the normal AC input, on/off rocker switch and honeycomb mesh grill. The additional switch is what lets you control the fan mode.

Towards the front, we find the eight modular connectors available.

Moving to the bottom we find the 140mm fan that cools the LZP-1000.

Eight modular cables are included with the power supply as well as four thumbscrews to mount the unit with.

Also included with the unit are a user manual, AC power cord and warning label that informs you about the additional fan switch on the back of the unit.

Cabling Arrangement and A Look Inside

Cabling Arrangement

As always, Kingwin does a good job of providing cables and connector availability. Natively wired we find the 20+4 pin Main, one EPS12Vcable, one ATX4+4 cable and two PCI-E cables with a single connector on the end. Also included are three more PCI-E cables, two of which have single connectors on them and one with dual connectors. This allows for up to three GPU's to be powered. Peripheral connectors come in the form of 3 SATA cables and one Molex+FDD cable. It would be nice to see Kingwin drop the FDD connector.

Rail distribution is as simple as it gets with a single 12V rail.

A Look Inside

Opening things up, we see that Kingwin has made sure there is sufficient cooling for the unit.

A pair of Nippon Chemi-Con caps adorns the primary side of the power supply.

More Nippon Chemi-Con can be found on the secondary side of the PSU.

Kingwin uses their own 140mm fan to cool the unit. Unfortunately we couldn't find a model number for this one.

Test Results and Final Thoughts

Test Results

Our load tests utilize a couple of FAST ATE active load testers and a variety of other equipment such as an oscilloscope, power conditioner, temperature probe and a power consumption meter. You can read more about our standard testing approach here.

The tests performed are based around six conceivable setups that are out there and progressively load down the PSU up to the power supply's limits or 1000W, whichever comes first. Since our test equipment's limits are equal to that of the Kingwin LZP-1000 1000W PSU, we can test it to the maximum.

Let's start by taking a look at the voltages to see how well this unit did during testing. Starting with the 12V rail, we see 2% regulation from with a total drop of .17V from start to finish. The 5V rail also stayed within 2% voltage regulation and displayed a total drop of .04V. Moving towards the 3.3V rail, we see that regulation was again within 2% with a total voltage drop of .04V.

DC output quality was excellent from start to finish. Starting out, we were barely able to see a ripple on the scope during Test 1 where we measured noise at a low 9mV peak to peak. This steadily increased as the loads also increased. By the time we had reached around 50% load, the unit ripple had crept up to 20mV. Under full load, we saw that the noise on the 12V rail had crept up to 32mV.

The Kingwin Lazer Platinum LZP-1000 is rated for 80Plus Platinum efficiency. This means that the power supply must perform at 90%/92%/89% efficiency at 20%/50%/100% loads respectively. As you can see, the Kingwin LZP-1000 1000W had no trouble achieving this while on our test bench.

Final Thoughts

Kingwin has produced another spectacular unit with the LZP-1000.

The unit has great voltage regulation, amazing DC output quality and platinum efficiency just as advertised. The ability for the unit to be nearly completely passive is a huge bonus, especially for those seeking silence.

Topping things off, the LZP-1000 represents an incredible value for a 1000W unit with Platinum efficiency, coming in at least $50 cheaper than the competition. Those seeking a 1000W unit would be crazy to not consider the LZP-1000W.
