The test system comprised of the following components:
Q6600 (overclocked to 3.5GHz)
Abit AB9 Pro
Powercolor HD 4870 512MB
2x1GB OCZ Platinum PC2-6400 DDR2
Antec 1200
Noctua NH-C12P
1x160GB Samsung Spinpoint HDD
7x case fans (6x 120mm 1x200mm)
The testing of the Signature PSU involved the investigation of the voltage stability using a Digital Multimetre. The voltages were observed whilst the system was completely idle and during a stress test with 3DMark06. This was done several times and the results were averaged out.
As you can see from the above graph. There was little to none discrepancy. The rails remained absolutely solid. You can be sure that this unit is extremely reliable and offers just what it says on the label.
As an additional test to discover the efficency of the unit I compared the Signature 650W against two other counter-parts. The Antec True Power Trio 550W and the OCZ Stealth XStream 600W. For this test I observed the idle and again 3DMark06 was run to obtain a full load on the system.
