A Closer Look

The Spire SP-500W power supply is designed to comply with Intel BTX 1.0a & ATX12V v2.03 specifications and is rated for a combined output power of 500 watts (550 watts maximum).  In addition to the big, shinny power supply the large box also includes a power cord, mounting screws, package of colorful cable ties, six modular cables, and a printed Manual.

The SP-500W power supply uses passive Power Factor Correction (PFC) and the incoming line voltage must be manually set with a small switch on the back panel.  The following table lists the specifications for the Spire SP-500W Rocketeer V power supply.

Notice that the Spire SP-500W does not have two or more +12V outputs, which is required by the newer ATX12V v2.2 specification.  However, the single +12V output is rated for 29A (348 watts), which should be adequate for all but the most power hungry SLI setups.

 

The SP-500W Rocketeer V enclosure is coated with a Titanium-look mirror finish and uses two cooling fans — (1) 80mm on the back and (1) 120mm on the bottom.  Both fans incorporate blue LED lights.  The rear 80mm fan runs at a constant low speed all the time while the 120mm fan speed is controlled by the power supply’s internal temperature, which is a function of the ambient temperature (internal PC case) and the load.

The US version of the SP-500W power supply uses passive PFC so the standard small, red selector switch is present on the back panel to select the AC line voltage.  The green push button allows the end user to manually force the 120mm cooling fan to full speed.  An LED located between the rear exhaust fan and PSU On-Off switch glows blue when the fan is forced on.

The main power and +12V power cables that supply the motherboard are hard wired into the power supply (which is my preference).  There are eight 6-pin connectors on the front panel that allow connecting the various peripheral power cables of your choice.  Latching connectors are used to insure cables don’t come undone over time.
