Page 1 - First Look

If today's review seems a little bit rushed, folks, I apologize. You see, I'm writing this on All-Hallows-Even, and we all know how things go down when the candy starts a-flyin.' One minute you're sitting there watching scary movies munching on M&M's, and the next you're sitting in the back of a police car because apparently it's illegal to run around shirtless with chocolate stains around your mouth and a viking helmet on your head chasing trick-or-treaters while yelling, "Bow down to Zuul, subcreatures!"

So, in order to avoid such potential hassles this year, I'm going to get this review done early so I can plan for the worst.

Kingwin is no stranger to this website. Most recently, I took a look at a new "Lazer Gold" platform from them in a 1kW flavor. That unit scored pretty well, if I do say so myself. If I do say so myself... what does that even mean? "Here's my opinion and I am unanimous in this!"

After Kingwin brought down the house with that well scoring 1kW model, I then took a look at the NZXT Hale90 850W, also based on this same Superflower platform. And that unit also scored very well. So, here we are today, and Kingwin wants to see if their version of the same 850W unit also does well. And I'm going to find out, as long as the lure of candy doesn't override my sanity long enough to get this done.

Like big brother, this unit is 80 Plus Gold certified. It will be very interesting to see how the efficiency comes out on this unit, knowing that I have a more accurate (read - more expensive) power meter than I used to.

Now, before I get too far into this review, I came under some criticism last time for being annoying. All I can say to that is... does this bug you? I'm not touching you. I'm not touching you. Hey, what's this on your shirt? You will... not... make... this... putt.

As was the case with big brother, this here Kingwin has a list of features to talk about on this side of the box. And lucky me, nothing's changed about the box, so I can get lazy and do the cut and paste thing.

Let's cut right to the chase here and get this box unpacked.

And here we have the contents - a power supply, user guide, power cord, thumbscrews, and a bag o' modular cables.

If the user guide looks familiar, it's for a good reason - you've seen it before. It's the same as the 1kW model.

Again, the power supply itself isn't anything we haven't seen before. It's the same platform as the Lazer Gold 1kW, and so it comes in the same package. I don't know about you, but I still like the way it looks.

As was the case with past Kingwin models, they've provided some soft silicone caps for the modular cable connectors. A nice touch, if I do say so myself and am unanimous in this.

I'm not touching you.

A look through the rear grille of the unit shows us a circuit board crammed full of parts.

Load testing will be coming up soon. Imma start chargin' mah layzur.

The modular cable connectors are those same crystal cube affairs Kingwin has been using lately. Good. I like these. I wonder if the LEDs to illuminate them are present in this model, as they were in the original Lazer.

Here's the overhead fan shot for you. While I don't care much for the contrast of the blue with the gold on the fan hub, I've seen worse. This fan does light up blue, by the way, like big brother's did.

Once again, Kingwin has seen fit to plaster a rather useless sticker on the side showing the fan curve. This type of thing looks better on a box with the rest of the marketing than on the power supply itself.

The top of the unit holds the spec label for the unit, as well as a patent sticker showing that, yes, Ultra Products got paid for the use of modular connectors on this unit.

And here's the spec label itself. As you can see, almost the entire capacity of the unit is available on just the 12V rail if desired. This tells me the VRM approach is used once again to derive the two minor rails. This approach is becoming almost universal on big units like this.

Like big brother, some cables are hardwired. And the hardwired cables make sense. We have an ATX connector, a 4+4 pin 12V connector for the CPU, and a cable for one high power video card. If you need an 850W power supply, these are the cables you're probably going to need anyway.

The crystal cubed modular cables. I was a bit surprised that they didn't include an 8 pin EPS connector in here - at the 850W level, I could see a second one coming in handy for some people. Ah well - not a big deal... just a minor annoyance.

Hey... wanna hear the most annoying sound in the world? Eeeeeeeeeeeeeehhhhhhhhhhhhhhhhh!!! Oh, wait, you can't hear it. Nuts. Just watch an episode of Merlin - that'll annoy you far, far worse than I ever could. Let me tell you - John Hurt is laughing all the way to the bank and back again on that job.
