Introduction

We would like to thank PNL-tec GmbH for supplying the review sample.

RASURBO is a brand of PNL-tec GmbH, which is a German company founded in 2005 distributing cases, power supplies and cooling products. RASURBO products currently span into three categories: cases, power supply units (PSUs) and fans. As they state the main feature of their products is the unbeatable price/performance ratio, a very proud claim indeed that we will keep in mind while conducting this review.

RASURBO currently has three PSU series: REAL&Power, GaminX & Power and ECO&Power. The first of the aforementioned series includes four PSUs with capacities ranging from 350W to 650W. The test subject of today's review is RASURBO REAL&Power 550W (RAPM550 here after) PSU. This unit is 80 PLUS certified, EuP/ErP ready, features a semi-modular cabling system and is backed by two years of warranty. The unit's strongest point is definitely its price, 60€. If it manages to exhibit decent performance then, with this price, it will be a good solution for a small home/office PC.

Specifications

All protections, besides Over Temperature are present. Price is on the low side but unfortunately the same goes for warranty which is only two years.


There are two +12V rails with non-matchd power distribution. The combined maximum power of +12V is only 70W below the unit's max rated capacity. Strangely the 5V rail is rated much lower than the 3.3V one, at only 15A max.

Cables & Connectors, Power Distribution

The number of peripheral connectors is limited. Also we would like to see one or, even better, two more SATA connectors. We are a bit surprised that RASURBO did not include an additional SATA or peripheral cable in the bundle since one connector is left unused on the modular panel when all provided SATA/peripheral cables are connected. Cable length in general terms is sufficient and the distance between connectors is the recommended by ATX spec. Finally all wires have 18 AWG size.


Power distribution is not good since the EPS connector feeds from the same +12V rail with the two PCIe connectors, which normally should be on a different rail. On top of that 12V2 is weaker than 12V1 by 8A! This is really weird. Either the power specifications on the manual/label of the PSU are wrong or the manufacturer did not choose the optimum power configuration for this model.
