Greetings once again, good readers. The last time I looked at a Kingwin power supply was back in June, when they sent me a Mach 1 1000W to torture. Well, they've come up with something else they would like you to buy - the Lazer 1000W.
Like the Mach 1, the Lazer represents one of the highest powered units in the Kingwin stable. It too features 80 Plus Bronze certification. But this time, instead of those old fashioned round modular connectors, Kingwin is giving us some fancy new "Crystal Cube" connectors. One wonders if they did so in response to my earlier criticisms of the older connector style.
At any rate, I reckon I better start showing you some box shots so we can toss this unit at the load tester and see if there are any other differences from the Mach 1. This shot shows you one of the few informative sides of this box, featuring some specs, some graphics of the dual color LED fan functionality, and claims that all of these square looking modular cable connectors can be swapped around all willy-nilly without worrying about zapping something.
Aha! I knew I'd find the marketing bullet points somewhere. I'll just get started reprinting all this now:

Whew, that was a lot of shift key pressing. Stable 12V current, eh? I guess that beats bragging about unstable 12V current. Or unintelligent fan speed control. More than 87% efficiency at 230V? Hmm... too bad I can't test at 230V. I'll have to settle for the usual 120V tests on page two and three.
Our look at the Lazer box concludes by opening it. Time for some unpacking.
The usual affair is found in the box. A plastic container of modular cables, a power cord, some screws, a manual, and a power supply.
And here's the manual now, which as it turns out is halfway decent. But only halfway. There are no 12V rail assignments printed therein.
From this angle, the Lazer doesn't look a lot different from the Mach 1, if any different at all. There's a little switch on the rear panel next to the AC receptacle, and the fan grille is a bit different, but that's about it.
Now we see some differences. Where the Mach 1 had those circular connectors on the modular panel, this one now has a double row of square Mini-Fit Jr. style connectors. And a big "Lazer" sticker on the side.
That red switch there is the switch for the fan and modular connector LEDs. It's a three position switch so you can go from blue lights to white lights to off as you wish.
This would be the spec label for today's Kingwin. You say you're feeling some deja vu? Well, that could be because you read the Mach 1 review. See, the specs are exactly the same for both models. Same 80 amperes split six ways from Sunday for the 12V rails, same high 5A 5VSB rail, same 170W combined 3.3V/5V rating. I wonder if most of the 12V rails are actually combined, like the Mach 1.
Here's a better look at the modular connector panel. As you can see, some soft rubber caps are included for these connectors that proved impossible to find on a white background.
Of the hardwired cables, we get the usual ATX connector, one PCI-E chain, one modular 4+4 pin EPS12V/ATX12V cable, and one 8 pin EPS12V cable.
Here are the modular cables. Looks like we get four more PCI-E connectors to play with for a total of six.
Type of connector:
Kingwin Lazer 1000W
ATX connector (520mm)
4+4 pin EPS12V connector (560mm)
8 pin EPS12V connector (560mm)
6 pin PCIe (560mm)
6+2 PCIe (+150mm)
5.25" Drive (520mm+150mm+150mm+150mm)
3.5" Drive (+150mm)
6 pin PCIe (520mm)
6+2 PCIe (520mm)
Unit Dimensions(L x W x H)
160mm x 150mm x 86mm
Opening up the unit to verify the 12V rail distribution, I found it to be rather odd. Like the Mach 1, several of the 12V rails are indeed bridged together. Only 12V4 appears to not be combined into some other rail. So, we essentially get a triple 12V unit here.
