Page 1 - First Look

Well, well, well. Look what I'm dealing with today - it's a kitty cat. And a big kitty, too. I must confess that being highly allergic to cats, I'm not too sure how I'm going to get along with...

You know what? It's always good to put one's glasses on before starting a review. Turns out the above picture is not of a kitty at all - I'm looking at the box of the new Lepa G900 power supply. A lot of you may be wondering what a Lepa is. Why, it's obviously how you pronounce the word "leopard" during a root canal when your dentist asks you routine questions like "how often do you brush, are you flossing regularly, and by the way could you say the word 'leopard' for me?"

Lepa as a brand is completely new to the market. Many of you will have never heard the name before. How about Ecomaster? Know that one? Ecomaster is a distributor for Enermax. Recently, Ecomaster decided to fire up a brand name of its own, and that brand is Lepa. Make sense? So, what we're looking at here is really Enermax by another name, right? Well... maybe. See, there's this other new name coming out of the Enermax camp called NAXN, which are value Enermax units not actually built by Enermax.

Confused enough? Good. Let's move on. Hmm... NAXN... Lepa... that must have been a busy meeting at the dentist's office that day. "Give me your top five names for the new brands while I chisel some teeth out of your jawbone, please."

Our next stop in the circle of confusing brands is this look at the back of the box. Lots of features are bragged about. Let's take a look:

  • 80 PLUSĀ® Gold certified with peak 93% efficiency.
  • 13.9cm fan with thermal programmed speed controller providing silent cooling performance.
  • Active PFC universal switching circuit improves Power Factor value up to 0.99, reducing AC line reactive power loss to minimum level and automatic adopting AC voltage from 100-240V.
  • 8P PCI-E connector supplied supporting extreme graphic cards.
  • Protected by Over Power, Over Voltage, Over Current, Short-Circuit, and Brown Out protections circuits.
    -They don't say it on the box, but this unit also provides brown nose protection as well, for you wealthy CEO types out there. Simply take the unit and wallop the offender upside the head with it. He'll go to the hospital, and you'll go to jail, but at least you won't have any problems with people sucking up to you anymore.
  • CPU 12V connector rail with >18A output to support next generation > 6 cores processor structure.
  • Extending CPU connector cable to 60cm facilitates installation with bottom-mount-PSU chassis.
    -Ah, but is it really 60cm? I'll measure that a bit later on and see.
  • SATA power connector with 3.3V rail to support new generation SSD.
    -Funny how an intrinsic SATA spec is now a "feature." 3.3 volts was always intended to be at the SATA connector. Some SATA hard drives require it. Don't be amazed this unit has 3.3 volts at the SATA connectors, be pissed off if you bought a unit that doesn't. Because it has to be there if a unit has SATA cabling at all.
  • Modular design for easy cable management and flexible system upgrade support.

This side of the box is one big helpful diagram as to which connectors come in what numbers on both this unit and the 700 watt model in the series.

Like most power supply boxes, when you open this one you see power supply related items. Let me unpack so you can see them.

Included with our kitty cat themed box we have a power supply, some screws, some modular cables, a power cord, and a user guide.

Here's the user guide, which features a disappointing lack of information about the 12 volt rail distribution of the unit. Since this is a quad 12V unit, it would be nice to know which cables and connectors are fed from what rail. Now I have to take it apart so I can tell you what's what. Yeah, I was going to do that anyway, but now I have to do it sooner. I have been slightly inconvenienced! They're making me work! How dare they!

The power supply itself is finished in a matte black, yellow, and gold color scheme. That gold fan is a little bit tacky looking to me, otherwise this would be one fantastic looking unit.

Here you can get a glimpse of the modular connectors, which all have arrows so you can tell which way is up. Or down.

Uhhh... guys? You put this label on crooked. Nothing says "quality" like a crooked label. Maybe "quality" went to the same root canal happy dentist as the folks who came up with the names "Lepa" and "NAXN."

Looks pretty busy in there behind the exhaust grille. A lot of that grille space seems taken up by a big transient filter PCB at the AC receptacle.

Yeah... that's a tacky looking shade of gold there. I get it... you have an 80 Plus Gold unit here. Hasn't the novelty of drawing attention to that fact waned a bit now that I've reviewed Platinum units a couple times now?

Before I go on, see that warranty sticker up there? It peeled right off, leaving no residue at all. Heck, it was already peeling by itself. You folks at Lepa might want to get on that issue. I've heard of people gutting high power units and dropping in junk to RMA. We don't want to help them do that easier, do we?

Here's the label for the unit. As you can see, the combined 12V rating is also the full output power for the unit. This implies that the other rails have no minimum load rating. We're going to have to check that out in load testing.

The four 12V rails on this unit are rated at 30A. That means the overcurrent protection is probably sitting at more than 40A. More than enough to prevent shutdowns, if they designed the cabling right.

The modular cables plug in here. Since there is no helpful info on what 12V rail goes where, I opened up the unit for you to check. From left to right: 12V4, 12V3, 12V2, 12V2, 12V2, 12V2, 12V3, 12V3.

And now we see the cabling. Let's have us a table:

4+4 pin EPS12V/ATX12V (590mm) 1

Some interesting decisions were made with this unit. The unit itself has three red modular connectors for PCI-E cables, while the modular cabling only supplies two cables for those connectors. One of them will therefore never get used. And what do we have on the hardwired cables? Two CPU connectors. Some boards will use both, many will not. Why not make one of these two modular, and able to use that third red connector?

I don't get it. I mean, the two hardwired PCI-E cables make sense. A rig needing a unit this size will probably need both. But it may not need the extra CPU cable. Don't get me wrong, it's nice that they provided the extra CPU cable, but this unit could have been so much cleaner in the cabling so easily that I can't figure out why they didn't do it.

And see that? Huh? Those hardwired CPU cables are not 60cm like the box promised. They're 59cm. I want my 1cm of cable! And I want a hairbrush that doesn't pull out a single strand of hair! And I want all my speaker cables to be the same length! And my car must be parked exactly 10 steps away from the door! When I buy eggs, I expect them to all be the same shape and size, too. I'm not being too picky, am I? Well, I guess they are 60cm if you count the connector, but don't bring logic and reason into this party, man.
