Good day to you fine people, and welcome to 2012. Fear not - I'm not going to sit here and make jokes in today's review about the supposed apocalypse at the end of the year, or the Mayans, or Planet X, or any of those loony theories. My reasoning is simple - the world actually ended some time in the nineties. Seriously, people... we have the entertainment industry buying new laws that favor them even as they sue their own customers into oblivion, Verizon had to be talked out of charging you a fee to pay your own bill, and the TSA is busy groping anyone who takes a plane to anywhere. I mean, the world has to have ended with all that stuff going on. It's just the only logical explanation I can come up with. And we have all these power supplies coming out at Platinum efficiency too, which was once considered darn near impossible.
So, for my fellow dwellers of the afterlife, I am reviewing yet another big bad mamma jamma Platinum unit. This time, it's from Kingwin. Who, thanks to Superflower's recent winning ways, should provide some strong competition to that big Seasonic I looked at not long ago.
But before we go any further, a list of features.
Support Intel Sandy Bridge /Core i7-980X /Core i7 /Core i5 /Core 2 Quad /Core 2 Duo & AMD Phenom II X6 /Phenom II X4 /Phenom II X3 /Athlon 64 X2 High Performance CPU -Uh, guys? You forgot a few. What about Athlons? Durons? Athlon XP's? Pentium III's? K6's? 486's? Seriously, any capable unit can power any modern CPU. I don't think we need quite such a long list on our boxes, do we?
Compliance with ATX 12V v2.2, EPS 12V v2.91, and SSI EPS 12V v2.92 Specification
Crystal Cube Modular Plug w/ Patented Power Connector Cable Management System (6 connectors for LZP-550/650/750, 8 connectors for LZP-850/1000/1200) -Patented by Ultra Products.
Hybrid Dual Voltage Automatic Switch System (Patent)
Superior Vertical Double Layer Main Transformer (Patent)
More than 2,000 Times ON/OFF Test
80 PLUS® Platinum High Efficiency Power Supply Certified -We'll see about that on the next two pages.
Full Range Design from 115V ~ 250V (Active PFC) -This is expected in anything this highly efficient. I'm not even sure a 1kW or bigger unit could be done without APFC in the first place in a modern 115V household.
50% Load (92% Efficiency), 20% Load (90% Efficiency), 100% Load (89% Efficiency) -Yup, that's what it takes to get Platinum.
Over Power/Under Power/Over Voltage/Short Circuit Protections
Stable + 12V Current -I should hope so. We'll see how stable by and by.
140MM Fan -Kingwin really needs to lay off the caps lock. Improper metric notation FTL. A small "M" means milli. A big "M" means MEGA. I'm guessing this does not have a 140 MEGAMOLAR fan.
Intelligent Auto Fan Speed Control
Compatible with Crossfire/SLI -Expected in a unit this size.
Two Way Switch Thermal Control System (please refer to manual for detail description)
ECO Intelligent Thermal Control System (Patent) (see diagram below): -Oh, no you don't. I'm not reprinting the graph. See the above picture.
Elsewhere on the box, we find this list of specifications. It's a bit hard to make out, but I can read it just fine so I won't reprint it. The cube connectors are a brand new concept, are they? I haven't been seeing them since the original Lazer, have I?
Here's the box all opened up. Let me just unpack, here.
We get a power supply, a power cord, velcro bag of modular cables, some thumbscrews, a user manual, and a warning sheet about the fanless mode.
And here's the relevant part of that warning sheet now. This info is indeed located in the manual, but a lot of people don't read that manual so it's probably not a bad idea to include this.
Speaking of the manual, here it is. Not the most comprehensive I've seen, but it has most of the basics in there.
And now, the power supply itself. Matte black - nice.
Another angle. Looks like we get more of the silicone connector caps on the modular connectors.
A look at the exhaust grille shows us the red switch used to enable the semi-fanless mode on this unit. In this shot, it is enabled.
Only one side of the unit has a sticker like this - the other side is plain old matte black.
And now, the load table.
Max Power @ 50 °C
I must confess, that 5VSB rating seems odd. Most units carry no less than 3A on that rail these days. This won't be an issue for most people, but you know what? Just give me that last half an ampere. Chances are the unit can handle that fine, so why stick it with a 2.5A rating when the rest of the competition is at 3A?
Another look at the modular connector panel. These connectors do not light up, by the way. Seems Kingwin is too serious these days to make stuff glow in the dark. Not that I mind - I have a windowed case in my bedroom rig, and I don't want the thing keeping me awake at night.
The modular cables.
And the non modular cables. I'd like to see that extra EPS12V moved to the modular panel, but otherwise this isn't too bad for hardwired cables. You're probably going to need both PCI-E cables anyway if you need a unit this big.
