A Look Inside
Next, we open up the power supply to take a quick look at how well things are built where it really counts. Please keep in mind that opening a PSU will void your warranty and can be dangerous.
The main board looks organized with good, clean soldering on the bottom side. There is some glue and plastic film to ensure no shorts occur. The heatsinks are made of a light aluminum and look decently sufficient to cool a power supply of this capacity. The UL code indicates the power supply is either a Magnell or ABS Computer Technologies unit, a division of NewEgg. Now, it appears this unit is based on the ATNG APL series power supplies. A quick review of the power supplies show that this is actually a 630W unit, not 650. It might explain the full load test results, but more on that later.
Here is a gander at the main capacitor in the PSU. It is Teapo branded and is common in value power supplies. Again, all standard items for this power supply category. Now, there is one interesting aspect on this power supply. All of the part numbers are rubbed off. I'm not sure why they would need to do that, unless they wanted to hide something! - I have seen other reviews note the very same thing, however, so I suspect that all retail versions of the PSU will be the same. Still, it makes you wonder.
Here is another look at the transformers. The large one at the top is the 12V source.
While I am inside the power supply, I like to trace back the rail mappings to see where things are sourced. Like many power supplies, it looks like we have four virtual rails shunted off the main 12V source. The power distribution is, as follows.
Now that we have a feel for the power supply, it is high time to run it through all the tests to see how it fairs. I am most interested in the hotbox test, especially considering the unit is rated at 30C and loses about 10% for every 10 degrees above that. Off to the torture rack we go.
