Hey man! Welcome to today's review man! Today, I've got the power, man! More specifically, I've got the Inwin Powerman IW-P600CQ3-2 in front of me for reviewing. At one point in time, Powerman used FSP as a source for their units. Now, they've moved away from FSP and have started using CWT. But, in between these two OEM's, they actually made a unit or two themselves. This is one of those units, the CQ series 600W. Boasting two PCI-E six pin connectors and quad 12V topology, the unit promises to be a good budget unit.

We'll get things rolling, once more, with cardboard shots. In the above picture, you can see that this unit is 80 plus certified. A quick jog over to the 80 Plus website shows the unit to have passed standard certification with a typical efficiency of 83.54%. Well see how that shakes out on my load tester later on.

The box isn't too forthcoming with the details on this unit, at least on this side, but there are some interesting things up there to talk about. See that second picture up there that says "Thermostat SW?" If you're anything like me, you're probably wondering whether that means this unit can control when your household furnace turns on. You say you're not like me? Well, that's probably for the best.

Hmm... apparently, the Powerman 600W contains a small car engine. That list of features is too small to read in the picture, so I'll do some typing for you here, with me being a smartass in italics:

  • Fully-Automatic Thermostat Switch Control (Thermostat SW) - Automatically detect temperature, initiate exhaust fan operation, as well as control ultra low speed fan operation, provide more effective and completely silent operation - ah, so that's what it does.
  • High Efficiency Power - Four sets of 12V power outputs can concurrently power up motherboard, CPU, and two video cards. Supply 4 times of the regular power! - what quad 12V operation has to do with efficiency is unknown to me. Four times of the regular power? Okaaaaaay. I'll take "Snake Oil" for a thousand, Alex.
  • Ultra Powerful Thermal Cooling - Two ball bearing fan is highly durable to ensure smooth airflow in the unit. When paired with the automatic thermostatic switch control, the fan is automatically activated as needed in contributing to overall energy efficiency - that does it, I'm going to load test with that switch enabled, and watch the power consumption to see how much difference the fan makes.
  • Excellent Performance - Certified by 80 PLUS US energy efficiency organizations, which indicates at least an 80% or above power efficiency. In fact, the IW-P600CQ3-2 can achieve up to 85% energy efficiency. When integrated with the all-new power distribution system, it greatly adds to the computer's overall stability of operation! - sorry, guys, but 80 Plus has nothing to do with stability. Quad 12V operation has nothing to do with stability. Only the overall circuit design, in other words if it's independently regulated or not, will tell that tale.
  • User Friendly
    • The IW-P600CQ3-2's Full Range Active PFC design can be used around the world - this is true
    • With 600W high efficiency output, it offers extreme gamers the most reliable power source for their machines - must be an old design, for there are no 8 pin PCI-E connectors, and I seriously doubt two 280's will like this unit.
    • The unit also includes 6 PIN x 2 for PCI-E VGA Card, SATA x 4 for high-capacity SATA drives and motherboard, CPU, and other peripherals for up to 8 sets of power connectors for expansion and convenience - I reckon those SATA connectors will also work for low capacity drives as well.
  • High Reliability - This durability is based on the following statements:
    • ACTIVE PFC meets EN61000-3-2 Class D - means it meets IEC standards for harmonic current draw from the mains.
    • MTBF achieves 100KHR's @ 25°C per MIL-STD-217D/E - hands up, those who actually run their supplies at 25 degrees. You'll notice my own hand isn't up. The hot box is unforgiving... muahahahahaha!!!
    • Operating ambient +10°C minimum to +50°C maximum - we'll just see about that
  • Safety Features - Our built-in protection to prevent five major hazardous areas: overheating, over-current, over-voltage, over-power, and short-circuiting. With these safety features, there is one less thing you need to worry every day - I thought you said there were five major hazardous areas... what about the other four? But seriously, a full compliment of protection circuitry is a good thing, and I'm glad they threw it all in here.

Opening up the box, we see Power Man enveloped by the Foam Creature. Will our hero be able to escape in time to save our planet from certain doom when billions of Foam Creature minions (also known as styrofoam disposable cups) attack?

Why yes he will, in fact. As you can see, that little plastic bag has gotten sick all over the inside of the box, puking its contents of screws all over the place. And of course, I'm going to have to be the one to clean it up.

The contents of the box arranged for your amusement. We have a power supply, power cord, and an owner's manual that turned out to be a surprisingly thorough affair printed on a single big sheet of shiny paper and folded up into pamphlet form.

Looking at the back panel, you can see the thermostat switch itself sitting just below the AC receptacle. As it turns out, that little metal looking thing right above the power switch isn't a screw but a dual color LED that glows blue when the unit is in standby mode, and green when the unit is running.

I'm not seeing much sleeving here, are you? From the looks of it, the fan is a simple 120mm unit.

What'd I tell you? Is that little owner's booklet packed full of info, or isn't it? I won't go to the trouble of reprinting all of this in here, but the manual is done up in several languages and nearly requires the borrowing of a microscope to read it all.

Time for a label shot and a load table. There's not really anything out of the ordinary to talk about here, except the UL file number, which comes right back to Inwin Development. And apparently Power Man's superpower is the ability to throw huge wooden stakes at people. Lightning bolt, you say? Can't be that - Zeus already has that one taken.

Yeah, definitely not seeing much sleeving up there. Only the ATX cable, to be specific. The rest of the cables are done up in a tangled rainbow of color. Here's the connector count table, along with 12V rail designations for you. What's interesting is that they did something unusual with the SATA chains - namely, they added standard four pin Molex drive connectors to the ends of each. This is in addition to the one chain of four pin Molexes.

I'll see you on the next page.
