Page 1 - First Look

As we look at the above picture, we can only come to one conclusion - it's time to get high on power once again here at Today I'm looking at a new entry into the 80 Plus Gold market from High Power in the Plus Gold one kilowatt model.

Let's get the albatross out of the way first. Yes, this is indeed a different way to package a power supply for retail. It's like a mixture of plastic blister packaging and cardboard. And I'll give them this - it stands out above the crowd. But there's one thing it doesn't do very well, and that's protect the unit within from shipping damage, whether it be of the cosmetic or functional sort. I don't know about you, but I'll take function over form any day. This packaging really wouldn't be so irritating, though, if it wasn't so big. Look at the picture again... that box is fourteen and a half inches long and eleven and a half inches tall, and a good fifth of the display area is dedicated to showing off those radioactive green connectors.

I just don't care for this packaging. The plastic over the power supply itself was already cracked in places. But let's have a look at the back and see if we can find some marketing to talk about.

Uh, yeah. There's some marketing stuff on this panel, all right. I won't reprint all of it, because a lot of it's not in English, but I'll try to get all the good stuff:


  • 80 PLUS Gold certificated unit provides typical 90% efficiency
    -Uh... hold on, now. 90% only applies to the 50% load level. It is required to pass Gold. Often, units will exceed 90% at this load level, just because they have to pass at 20% and 100% load levels as well. We'll see how this works out on the following pages.
  • The particular Golf Surface fan for the more airflow
    -I'm so glad our golf surface is particular. We wouldn't want that Shooter McGavin fella around here. You... do know what that guy eats for breakfast, don't you?
  • Ultra silent 2-ball bearing 13.5cm fan
  • Industrial grade components for better reliability and stability
    -Always a good thing, those industrial grade components.
  • Support multi-GPUs
  • Active Power Factor Correction(>0.99)
  • Advance double-forward circuit design
  • Full scale protection provided
  • Safety and EMI approvals

To the right, we see a few more features talked about:

  • Fan Delay off
    fan speed control and delay shut down by continue running after a system shut down and will turn the fan off approximately few seconds then for components lifetime extended
    -I... think they mean the fan runs after shutdown for a while to keep cooling the system. A nice feature to have.
  • Reliable Japan-made solid-state capacitors
    enhance your system durability and stability even under extreme conditions
  • All output cables with Nylon sleeve
    cable sleeve avoids cable clutter, allows neat and easy installation for an improved airflow
    -Yes it does, and I'm always glad to see it on any power supply.
  • Eight PCI-Express Power Connectors
    sufficient and stable current to fully support SLI & CrossFire Systems
    -Eight? Gadzooks! That might be a little too much load for a 1kW unit with...
  • Quad+ 12V Output Rails
    ensure safe and stable system operation under heavy operation
    -But only if you don't overload them to the point the overcurrent protection steps in and says, "nope, too much, I'm shutting this down now." We'll see if the rail distribution and current ratings make any sense a bit later on.
  • Advanced Double Forward Circuit and Double-Layer PCB
    more reliable, high efficiency and powerful power supply
    -Nothing new here... double forward topology has been around since forever now.
  • Golf Surface Fan
    for more airflow with less noise than standard
    -Will this help me land my very own Subway endorsement deal?
  • 100% reliable Japan-made capacitors
    longer lifespan than electronic capacitors
    -This just in... Japan made capacitors ARE electronic capacitors. I know, I know, that's quite a bombshell I just gave you readers. Sorry.
  • Cable Management
    freely select wiring harnesses as you need. Specific color connectors and infixed socket with sticker design can assist in the installation
    -I had an infixed socket once. Last time I go to that dentist.
  • Ultimate balance between cooling and noise level
    extreme low noise and level using Smart Fan Control Circuit. Increase silence, extend fan life and more reliable performance by eliminating unnecessary high RPM
  • Patented Easy Swap Connector
    quick and Easy installation
  • Honey Comb Structure with the best ventilation
    optimum structure for the best ventilation and maximize air flow tosolve potential thermal and noise problem. Reduce the air resistance to minimum

There's more to the box than features written in Engrish. On both sides, we get several blurbs about what 80 Plus is, what EuP is, and what RoHS is. I won't go into detail here... after picking on the Engrish on the back of the box, I'm more than ready to hack my way into the packaging and get at the stuff inside.

And here we have it - the contents of the box. A power cord, bag of modular cables, user guide, and a power supply.

The user guide is a so-so affair. It mostly sticks to the basics like installation and troubleshooting, but does go into a bit more detail than the box did on what protection circuitry is present: overcurrent/undervoltage, overvoltage, overtemp, short circuit, and overload. The manual is lacking when it comes to 12V rail distribution data... I had to go rustle up the downloadable mechanical drawing sheet on the High Power website to get that info.

Here's the power supply itself. Matte black and yellow seem to be the operative colors here today, with the fan and its grille done up in gold. I must admit, this fan is rather less tacky looking than the one I saw in that Lepa 900W unit last week. It still looks a little overly flashy to me, and the color doesn't really match the yellow label that well, but it's not terrible looking.

As you can see here, High Power did indeed color code the modular connectors. This should help us tell in a hurry which connectors go where. Wait... what's that sticker up top? Let me zoom in, here...

Aha. It's a warning sticker that tells us that the fan will be indeed operating after system shutdown for a couple minutes.

This would be our honeycombed exhaust grille. Lots of guts are packed inside this unit, it seems.

A better look at that side sticker for you. This is what you'd see in a windowed case.

Whoops! High Power has some cable grommet issues to deal with, for this one completely popped right out of there. It's not too big of a deal, as the metal isn't sharp and the cables are all sleeved (in fact, many companies wouldn't have bothered with the grommet at all), but still... if you're going to use a grommet, make it a good grommet.

Hey! Happy Fanmore! Drive it 400 yards!

I do like that fan grille. It's almost like the sheer torque of the fan below twisted it so hard it deformed the structure. Not that any fan I ever met could do that.

Here's the load table sticker. As you can see, this unit is good for all one thousand watts right on the 12V rails, which indicates that it's probably using the voltage regulator module (or VRM) approach to the minor rails again. That is what VRM stands for, right? They haven't changed it to "Viscous Rutabaga Marshmellows" or anything like that? Ah good. I was worried there for a second.

For a modular unit, this power supply comes with an awful lot of hardwired cables. Included is a SATA cable that starts at the power supply and stretches all the way to Kalamazoo. Unless, of course, you're in Kalamazoo; in which case it starts there and ends up on Mars. This really is too much length on this one cable. I mean, it's almost four feet from power supply to the final SATA connector!

Also among the hardwired cables are four PCI-E cables, each with its own connector, one EPS12V cable, and one 4+4 ATX/EPS cable. A little too much cable clutter on what's supposed to be a modular unit, says I. Let's at least get that long SATA cable on the modular panel, shall we?

Speaking of the bag of modular cables, here's what I found inside it: some modular cables, a case badge, some thumb screws, some zip ties, and some velcro ties. Let's have a peek at the cable table now.

Type of connector: High Power Plus
Gold 1kW
ATX connector (530mm) 24 pin 12V1
SATA (570mm+185mm+185mm+185mm) 4
6+2 pin PCIe (580mm) 4 12V1/
4+4 pin EPS12V/ATX12V (580mm) 1 12V2/
8 pin EPS12V (560mm) 1 12V4
Modular Cables
5.25" Drive (535mm+185mm+185mm) 6 12V3/

3.5" Drive connectors (+185mm)

SATA (485mm+185mm+185mm+185mm) 8
6+2 pin PCIe (585mm) 4
Unit Dimensions (L x W x H)
160mm x 150mm x 86mm

You will recall that each 12V rail is rated to 30 amperes. Based on what I see above, there really doesn't seem like there was a plan on what connectors to put where... everything's just kind of thrown onto the unit willy-nilly. Half the modular cable connectors are on 12V3, the others are on 12V4. The hardwired SATA cable shares 12V1 with the ATX connector and two of the hardwired PCI-E connectors.

It's fortunate that the overcurrent protection on the 12V rails is set high. Much lower, and we might have run into shutdown issues on this unit when using high power video cards. As it is now, however, you do have some options for moving stuff to other rails if you end up encountering a problem.
