Page 1 - First Look

Allrighty. I think I'm ready for this review now. I have my Platinum Blonde CD all ready to go, a couple of good speakers handy, and I have a lighter to wave in the air. No, I'm not wearing an 80's hair metal wig - that's my real hair. And now, to start this review.

Platinum Blonde is a Canadian band who had their heyday back in the 80's with hits like... wait a minute, I'm reviewing the wrong thing again, aren't I? Sigh. I was going to play air guitar and everything.

Originally, the 80 Plus program only went up to 80% efficiency. It was nice and simple. Power supplies that passed were better than 80% efficient at loads between 20 and 100 percent. The world cheered. Then came Bronze, a certification level that guaranteed 82% minimum efficiency. The world cheered. Silver followed, promising 85% minimum efficiency. The world cheered again, and clamored for more.

Enter Gold, which said we could expect 87% minimum efficiency. Again, the world cheered. Surely, people thought, that would be the end of it. We now had every Olympic medal level represented, and computer power supplies had gotten about as efficient as they could get.

Well, 80 Plus didn't stop there. Today, we have yet another new certification level to talk about - Platinum. And we have a brand new unit based on that certification to review: the Kingwin Lazer Platinum 550W.

Before I speak of the marketing on the box, you may be asking, "what is Platinum?" Why, it's a chemical element. Don't you remember your periodic table? Me neither. All kidding aside, the 80 Plus Platinum certification demands that the power supply in question be 90%-92%-89% efficient at 20%-50%-100% loads. It slides into the 80 Plus certifications chart in between Gold and the as yet unannounced Unobtanium certification levels. I'm sure that one is coming soon, and will require the unit to be, at minimum, 105% efficient.

Ok. Enough efficiency bibble-babble fiddle-faddle. On to the marketing:

  • Support Intel 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
    -What? No Cyrix MediaGX support? I'm shocked and appalled.
  • 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-550/750, 8 connectors for LZP-850/1000/1200/1300)
    -Very interesting - this implies that we're getting a whole line of Platinum units eventually. It will be interesting to see them pull this off, if possible.
  • Hybrid Dual Voltage Automatic Switch System (Patent)
    -Uh... huh? To be honest, I have no idea what they're talking 'bout, Willis. Does this mean these run on a different voltage in a Prius?
  • Superior Vertical Double Layer Main Transformer (Patent)
    -As opposed to all those inferior vertical double layer main transformers that are now choking the market, I guess.
  • More than 2,000 Times On/Off Test
  • 80 PLUSĀ® Platinum High Efficiency Power Supply Certified
    -Hooray for Platinum!
  • Full Range Design from 115V ~ 250V (Active PFC)
  • 50% Load (92% Efficiency), 20% Load (90% Efficiency), 100% Load (89% Efficiency)
    -Uh... yeah. You pretty much already said that when you said it was Platinum certified.
  • PCI-E 6Pin & 8(6+2) Pin Connector Satisfy High-End Graphic Card Requirement
    -But only one high end graphic card, right? Some of the more power hungry cards will be a little much for a 550W unit if used in pairs.
  • Over Power/Under Power/Over Voltage/Short Circuit Protections
  • Stable +12V Current
    -We'll let the SunMoon be the judge of that on the following pages.
  • 140MM Fan
    -140 megameters? Wowee! I've never seen a power supply fan that large! How did they get it into the box? Clearly, Kingwin got some help from Doctor Who. The box must be a TARDIS. Hey... that means I can go back to the 80's and watch Turbo Teen and The Wizard again! Then I can go forward to the year 5345 and see the final season of The Simpsons! It might even be funny again by then! This is going to be the best review ever!
  • Intelligent Auto Fan Speed Control
    -I'll administer an IQ test later. The fan controller must equal or better my own score of 153 for me to call it intelligent. Otherwise, I may have to break out the dumb platinum blonde jokes. Oh sit down, lady, and put the rifle away... I'm a strawberry blonde myself.
  • Compatible with Crossfire/SLI
  • ECO Intelligent Thermal Control System (Patent) (see diagram below)
    -I won't reprint the diagram here, but basically this means that the fan controller operates in fanless mode up to a certain point. We've seen this before, most often in designs based on the Seasonic X series units.

Here is a close-up of another graphic on the back of the box. It looks like Kingwin wants to slide us some extra power under the table, in the name of giving us Gold performance to 650 watts.

I have mixed feelings on this. I don't like it when I see peak ratings on units. There is never any guarantee that these ratings are attainable. But, on the other hand, this is a Platinum unit. I have no trouble believing that this efficiency level leaves at least some gas in the tank.

Usually, I don't test claims like this. But, if I can find a load table or something that indicates how I can do this safely, I suppose I'll make an exception and do it this time.

This side of the box details a few specifications, most of which are repeats of what I already showed you, and some pictures of the modular connectors and that 140 megameter fan. You know, if that fan is really that big, those connectors and the housing must be monstrously huge in comparison. I hope I can lift this unit without a crane.

Well, my bubble's been burst. There's no way there's anything like a 140 megameter fan in there. Let me unpack.

Attention. This unit operates fanlessly at times. Good to know.

Here's the manual. I've seen better, I've seen worse.

The contents of the box includes the fan warning paper and manual we already saw, a bag of screws, a bag of modular cables, a power cord, and a power supply.

Here's the power supply itself. The fan is actually a light gray, which doesn't really do much for me. It's kind of bland.

Another angle. Kingwin is still throwing in those silicone covers for the modular connectors, I see.

Another good look at the fan.

Here's the exhaust grille for you, with a couple of bright blue capacitors playing peek-a-boo with each other just inside.

Like the box promised, we have six of those crystal cube connectors on the front. They all interchange with each other, so there's no need to worry about plugging cables into the wrong connectors.

As you might surmise from the high 12V rating on this unit, we've got the VRM approach on this unit again. This means that the minor rails are all pulled off the one big 12V rail through the use of voltage regulator modules.

Kingwin LZP-550

+3.3V +5V +12V -12V +5VSB
20A 20A 45.5A 0.5A 2.5A
Max Power 100W 546W 6W 12.5W

Like most modular units, there are still some hardwired cables present. Normally, I get a little grumpy when I find duplicates on the hardwired cables. But, of the two PCI-E cables we can see, one is a 6 pin and one is a modular 6+2 pin. So, I'll let it slide just a bit this time.

All modular cabling is done with black ribbon cables. These can make it easier to route them inside one's case, but they also make it hard to see which wires are for what rail.
