Kingwin LZP-1000 1000W Power Supply Review
Kingwin does not bring a huge number of power supplies for review, but when it does bring one to our attention it is usually a very worthy competitor. Today is no different. This new 1 kilowatt computer power supply brandishes sought after modular connections along with a very efficient design that has very much impressed us.
Overview
The first thing we are going to look at with the Kingwin LZP-1000 is its packaging, accessories, and documentation. While normally none of these items is a make or break item for a power supply the packaging quite often contains a lot of information about the product we are purchasing. The inclusion of an owner’s manual that provides actual information about our product is also of great help. Accessories are almost unnecessary with a power supply as the unit is self contained, unless it is modular, but there are cases where a manufacturer can include useful accessories to make installation, routing, and use more efficient.
The packaging for the Kingwin LZP-1000 is very much like that of the first 80Plus Platinum unit we reviewed, the LZP-550. Once more, the packaging is large and trimmed in black and platinum colors. On the front of the packaging, we once more find the 80Plus Platinum seal, a 5 year warranty, and a little bit of information about the unit's "Special ECO Intelligent Thermal Control System." A quick check of the 80Plus website does indeed find this unit rated for 80Plus Platinum and we will look at this again in a bit. When we swing over to the back of the packaging, we don’t see any SLI or CrossFireX certifications and, at the time of writing, we don’t find the unit certified for either multi-GPU configuration on the respective websites. What we do find on the back, however, is a long list of advertising bullet points, and two interesting pieces of copy that we saw on the LZP-550. Indeed, this appears to be the exact packaging as we saw with that power supply with one exception. The blurb that was carried by the LZP-550 and STR-500 about "Overclock Version" and "Can be overclocked to 650W continuous at 80+ Gold Rating" is finally, and thankfully, gone. This previous statement was not exactly a true statement as power supplies aren’t "overclocked" like a CPU or GPU. So, thank you Kingwin for killing that idea with this unit. Let’s move now and take a look at the power label, pulled from the packaging, and the connector count below.
The paper specifications for the Kingwin LZP-1000 are very much like what we saw from the LZG-1000 previously. Both power supplies have a single 12v rail rated at 83A or over 99% of the unit's total possible DC output capacity if needed. Along with this 12v arrangement, we get a total capacity of 100W for the minor rails which is actually 20W less than what the cap was for the minor rails on the LZG-1000. This 100W cap is also significantly smaller than what we saw on the most recent 1000W 80Plus Platinum unit we reviewed, the Seasonic Platinum-1000. Indeed, this is particularly interesting as the unit has 12 SATA connectors and 6 Molex connectors. This very low 5v/3.3v rail capacity may be of some note to those users looking to run very large disk arrays. When we look back to the 12v side of things, we see that we have a total of 5 modified 8-pin PCI-Express connectors and 2 EPS/P4 connectors on the unit. For some reason we lose a PCI-Express connector on this unit compared to what we saw on the previous LZG-1000. Odd, but not necessarily a deal breaker unless you need 6 PCI-Express connectors.
Once we open the Kingwin LZP-1000 we see the power supply itself, the power cord, mounting screws, manual, an instruction card, and the modular cables in a pouch. The manual with this unit is 6 page long (in English) and provides some information about the unit including the basic electrical specifications, some troubleshooting steps, and basic features of the unit. Additionally, we find the same information we saw with the LZP-550 pertaining to the "ECO Intelligent Thermal Control System." Making a new appearance today in the manual, and on the instruction sheet, is the information pertaining to the "Two Way Thermal Control System." This information is as follows:
Two Way Switch Thermal control System
1. Dual voltage circuit with thermal control system (Switch to Left or Down, position 1) *Initial Fan RPM is in low RMP status, will adjust its RPM automatically according to the internal temperature.
2. ECO Intelligent Thermal Control System (Switch to Right or Up, position 2) *Fan appears to be stationary in the beginning is normal phenomenon
3. Default setting is at Position 2 (ECO mode) (May switch two different modes according to your demand)
4. Please refer to the product itself for the exact position and to the manual for detail description.
After looking at the manual there is no more detailed description of the switch operation which is interesting given that the same information is on both the manual and the instruction sheet it seems the inclusion of the instruction sheet is a bit redundant and unnecessary. What we can find additionally in the manual, as stated earlier, is a figure describing the "ECO Intelligent Thermal Control System." Lastly, the warranty information is once more not found in the manual or the inside of the package. Can we change that going forward Kingwin? Let's move on now and see what this unit looks like once we open it up.
