PERFORMANCE

3.2 Short Circuit Protection

A short circuit on any DC output will cause the power to latch. The power supply will withstand a continuous short circuit to the output without damage or overseers to the unit. The +5VSB can be shorted indefinitely and will recover automatically when the short is removed.

3.3 No Load Operation

No hazardous conditions or damage to the supply will occur with all of the DC output connectors disconnected from the load.

3.4 Over Power Protection(OPP)

The power supply shall go shutdown when the total output load is over 110-160% of rating.

3.5 Over Current Protection

Overload currents applied to +12V1&+12V2 will cause the output to trip before reaching or exceeding 240 VA. For testing purposes, the overload currents should be ramped at a minimum rate of 10 A/s starting from full load.

4.2 Shocks & Vibration

The power supply will withstand the following imposed conditions without experiencing non-recoverable failure or deviation form specified output characteristics.

Storage -40G, 11mSec. half-sine wave pulse in both directions on three mutually perpendicular axes. Operating -10G, 11mSec. half-sine wave pulse in both directions on three mutually perpendicular axes. Vibration Operation-Sine wave excited, 0.25G maximum acceleration, 10-250 Hz, swept at one octave/mine. Fifteen-minaret dwell at all frequencies at which the device under test experience excursions two times large than non-resonant excursions.

RP500-2-S, RP550-2, RP500-2, RP550-2-S specifications

The Rosewill RP550-2-S and its siblings RP550-2, RP500-2, and RP500-2-S are notable power supply units (PSUs) that cater to a wide range of computing needs, especially for gaming and high-performance computing. These models, part of Rosewill’s reputable lineup, are designed with efficiency, compatibility, and reliability in mind, making them a popular choice for PC builders and gamers.

One of the standout features of the Rosewill RP550-2 and RP500-2 series is their certification for energy efficiency. Many of these models boast an 80 PLUS certification, which ensures that they deliver at least 80% efficiency at a range of load states. This not only translates into lower electricity bills but also helps in reducing heat output, leading to quieter cooling performance.

In terms of power output, the RP550-2-S offers a robust 550 watts of continuous power, while the RP500-2 and RP500-2-S provide 500 watts. This ample power capacity supports a variety of system configurations, allowing users to run mid to high-end graphics cards and processors without stability issues. The inclusion of multiple +12V rails provides better distribution of power to the components that require it most.

Cooling is another critical aspect addressed by these models. Featuring a 120mm fan, these power supplies ensure optimal heat dissipation while maintaining quiet operation. The fan’s intelligent design allows for efficient airflow, which is essential for keeping temperatures in check, especially during intensive gaming or resource-heavy tasks.

Connectivity options are generous across these models. They provide multiple PCIe connectors for graphics cards, SATA connectors for solid-state drives and hard drives, and plenty of Molex connectors for additional peripherals. This versatility allows users to build their systems according to their specific needs without running into compatibility issues.

Moreover, Rosewill places a strong emphasis on safety features in the RP series. With built-in protection mechanisms like Over Voltage Protection (OVP), Under Voltage Protection (UVP), Over Current Protection (OCP), and Short Circuit Protection (SCP), users can have peace of mind knowing that their components are safeguarded against potential electrical issues.

In summary, the Rosewill RP550-2-S, RP550-2, RP500-2, and RP500-2-S power supplies are designed to meet the demands of modern computing environments. With their focus on efficiency, reliability, and solid performance, these PSUs are ideal for both casual users and enthusiasts looking to build a stable and powerful PC. Whether you're gaming, working, or enjoying multimedia, these units deliver the necessary power and protection to keep your system operating smoothly.
