Let's talk about the exterior more.
Here we have the cables, and cost cutting is extremely evident. The wires are very thin, 20AWG, while the recommended gauge is 18AWG. The loadout is as follows:
x1 ATX 20+4 pin
x1 ATX12V 4 pin
x2 Molex
x2 SATA
x1 Floppy
The connectors are all different, colors, indicating that they were picked to come from the cheapest source. The SATA connectors are obvious modifications to an original design, being black vs. translucent or white like the original connectors.
The exterior casing is about as generic as it gets. Note that there is no sleeving on the cables at all, even a plastic sleeve where they leave the housing. That means that these thin wires with their thin insulation will be rubbing up against bare metal. Can anyone else say "inevitable short circuit"?
There is very little space for airflow. I forgot to mention earlier, the unit uses an 80mm rear fan. Ok, fine, but at least give adequate venting for air to enter the power supply. Instead it just has a few holes punched through the case metal, which is, by the way, 0.5mm aluminum that bends very easily.
Oh, and you can see where a zip tie holding an internal component comes through under the cabling. Whoops.
Here we have the specification table, which lists info on all kinds of LPJ2 models from 180W to 500W. I'm curious to look at the <250W models, because... Oops, spoilers.
Ours is the 430W model, which gives us:
+3.3V - 25A
+5V - 34A
+12V - 18A
Combined +5V and +3.3V - 190W Max
Remember those figures, folks, 'cause we'll be talking about them later.
Anyway, these amperage ratings are typical of a low-end power supply adapted from a Pentium 3-era design, when computers drew mainly from the +5V and +3.3V rails, instead of the +12V like modern machines. The +12V rail is beefed up a little, but really a "430W" power supply should have a +12V amperage of at least 32A, over half again what this claims it can do.
It also provides a service number which would be helpful for submitting an RMA when this garbage inevitably self-immolates, except that there's no warranty card in the box, no contact info on the outside of the box, and Linkworld's website is a ****ing turd. Wonderful.
Looking on the bottom of the unit we find--da da-DA! MORE COST CUTTING!!!! Rather than use, you know. $0.005 standoffs to lift the main PCB off the casing they just punch and raise sections of the case. Fantastic. This also gives the user an idea of how thin and flexible the casing really is.
Let's break the warranty sticker and see what's inside this piece of ****.
