Connectors & cabling
OK, lets start with this ATX-350W tragedy. The wires are 20AWG of course but I am not even sure if that is true. The copper wiring inside the cables is so thin a couple of the cables already broke from the board when I examined it. The molex pins are completely loose in the plastic package, this is common problem with these cheap units, it’s quite fun to connect this to some device when all the pins point in different directions. The only lonely SATA connector has cheap pins which are not gold-plated. The SATA standard itself calls for gold plating, that is why all the connectors I have ever seen always had at least some gold on them. Not this one. Forget about 500 mA per pin. All the wires are also terribly short. Copper is expensive ya know!
In total, we have:
- 1× Main ATX (20+4pin): 32 cm
- 1× ATX 12 V (4pin): 33 cm
- 1× SATA: 1× 33 cm
- 3× peripheral molex: 1× 32 cm, 1× 47 cm, 1× 50 cm
- 1× Berg for FDD: 64 cm
Casing & cooling
I am not sure if the metal chassis of the ATX-350W is even made from steel as it is paper thin (0.6 mm) and only finished with basic grey coating. Notice the “BURN-IN OK” sticker, oh yeah baby…something will definitely burn here. Maybe the flames will even burn all the way in to my table…
The intake part of the chassis uses an ordinary hexagonal mesh pattern. It uses 8cm fan which sucks the air from the unit internals. Fan grill is made from the casing of course, just by punching pieces out. They even used four screws, oh man, such a waste, that had to cost at least a cent!
The fan is a “cooling fan” brand. This takes no end man…it uses sleeve bearing and they probably used the minimum possible amount of Vaseline to make it spin. God knows for how long. Its frame allows to be mounted only on one side. Who needs more? That costs money! Let’s move on…
