OCZ Powerstream 420W Review - Results
(Page 4 of 5 )
The OCZ Powerstream was designed to be the ultimate overclockers' power supply. One of its key features is the ability to adjust the voltage. Since the Powerstream has adjustable rails, I am going to set up the voltages as close to the default voltage as possible at idle in BIOS: 12v will be at 12.01v, 3.3v will be at 3.31v and 5v will be 5.00v. To get my idle results, I let my system idle in Windows for 10 minutes, To get the load voltages, I ran Need For Speed Underground 2 to use the maximum power from the power supply unit.

- Abit AA8 Duramax (droop mod)

- 3x120mm Adda 80CFM Fans @ 12v
Considering the amount of overclocking, and the very low voltage drop, the power supply performs just as I expected: flawlessly.
