Cables:
The next image takes a look at the cables for the Rosewill RX630-S-B. You get all of the key connectors, but I would say that the quantity and length are a little on the light side. I was able to reach all connections in a mid-tower case, but I can tell that the 24-pin and 8-pin motherboard cables might be too short to allow for decent cable management in a full tower case.
The list below details the quantity of each connector provided:
» 1x 20+4-Pin Main Connector
» 1x 4+4-Pin ATX12V/EPS12V Connector
» 1x 6-Pin PCI-E Connector
» 1x 6+2-pin PCI-E Connector
» 6x 4-Pin Peripheral Connector
» 4x 5-Pin SATA Connector
» 1x 4-Pin Floppy Connector
Four SATA connections and two PCI Express connections may be enough for the typical user, but I know a 630W unit should be capable of more. The test system to be used for this review needs five SATA connections and three PCI Express connections, so I will be digging into my pile of adapters to make it work. Luckily the RX630-S-B has six 4-pin drive connectors, which aren't needed by me for anything but to power adapters for connectors that are lacking.
Internal Inspection:
I wasn't sure what to expect when I cracked open the Rosewill RX630-S-B Xtreme Series 630W power supply, but I didn't expect anything too exciting. The fan power lead has a connector which lets you disconnect it, and with it out of the way the internal lay out is easy to inspect. The heatsinks found inside are on the small to average side of things in terms of size, and the other electrical features such as transformers and capacitors seem fairly typical. Everything is rather neatly arranged, and the orientation will allow air from the fan to wash over everything with a clear path to the exit.
 
In case you didn't notice them in the images above, the next image shows something that makes this Rosewill PSU immediately much more interesting; a bank of four potentiometers. Having voltage rail adjustments is a much sought after feature with computer enthusiasts, but not something you find on many power supplies. The fact that there are potentiometers on a unit that sells for under $100 is pretty impressive.
