A Closer Look – The Box

The Rasurbo RAPM650 comes in a simple orange and black cardbox on which we find a photo of the PSU.

02 here are the voltages - Rasurbo RAPM650 Review

At the sides of the box we can find information on the voltages of the PSU, as well as the connections that are supported.  All the contents are nicely protected inside the box.

Included with the Rasurbo RAPM650 are:

 IEC connector
 Four screws to attach the power supply
 Five ties
 Modular Cable Assemblies


The modular cables come sleeved and the manual has installation instructions in case you encounter a problem. There are also four ties included to help you organize the cables, and of course, the power cable.


A Closer Look – The Rasurbo RAPM650 PSU

The Rasurbo RAPM650 has a nice black finish and feels well built.

At the back we find the power socket and an On-Off switch. We can also we see the mesh grill that helps on the ventilation of the PSU, combined with the 120mm fan.

There is a sticker at one side of the PSU that has an input,output and voltage chart. Under the modular connectors we find stickers that indicate the connection type to be used.

A Closer Look – The Rasurbo RAPM650 PSU Interior

Inside the PSU we can find very well designed high temperature capacitors and digital control circuits. Everything is well organized and carefully constructed, despite the fact that the interior is simple.


Test Setup and Procedures

The machine’s specs on which we tested the psu are:

Processor: Intel Core i7 920
Motherboard: Asus P6X85D
RAM: 6 GB Mushkin 6-7-6-18
VGA:Gigabyte GTX480 1536MB
HDD: Velocity Raptor 150GB
PSU: Rasurbo RAPM650
Case: Thermaltake Armor VA8003BWS
Operating System: Windows 7 64-bit

The tests that we ran included:


  • Idle Voltages (Rails)
  • Load Voltages (Rails)
  • Efficiency Test
  • Noise Levels


Test Results

The rail voltages proved to be stable and satisfying in both idle and load modes.

Pushing the PSU above its rated limits generates an  efficiency level of 80%. and it is very stable also. Noise levels are considered average for the category.



Honestly, we were surprised me with this unit. After examination of its simple internal design and small heatsinks we were not sure if unit will be able to perform well. But the PSU has exceeded our expectations! It delvered solid performance and worked well under idle and load conditions.
During our testing, the Rasurbo RAPM650 power supply was very stable and did not have any failures or other performance issues. The voltage fluctuations were minimal and the voltages stayed well within ATX standards.
The only downside to this PSU is the 2-year warranty, while other makers offer 5-year warranty. Costing around 70 euros, this is surely a PSU to consider.


(+) Single +12V rail with 52A
(+) Active PFC
(+) Efficient
(+) Good build quality
(+) All cables fully sleeved
(+) Good value for moneys


(+) 24 months warranty


Thus, we give the Rasurbo RAPM650 our Value For Money Award.
