Tech Review - OCZ PowerStream 600W PSU with Adjustable Rails
Hello again, my name is Rodney Reynolds and welcome to another video review. Today, I am looking at the OCZ PowerStream 600W Power Supply. What is included in this package are a number of Velcro straps, some cable ties, a power cable, the user’s manual and the four screws for mounting the power supply. This particular product has a wattage of 600 peaking at 700 which is more than enough power for today’s fastest computer systems. Now how is this wattage determined?
Well to understand that, you need to know what rails are. Rails are basically well regulated transformers which convert domestic current into voltages that your computer system can use and there are essentially two different rails, the 3.3/5V and the 12V. In this particular case, the maximum output of the 3.3/5V is 322W and the 12V is approximately 450W which is essentially how the wattage of this power supply is determined.
The 3.3/5V rail is responsible for the motherboard, memory, PCI cards, AGP card and so on while the 12V rail is responsible for the hard drives, DVD, CD-ROM, fans, etcetera. Also, some might be interested to know the amps on each rail. The +3.3V is 28 amps and the +5V is 46 amps. Now this power supply has two +12V rails, one is 20 amps and the other is 18 amps.
Now let us have a closer look at this product. It has a very reflective surface as you can see. This is a nickel plated chrome finish and it does give it a very cool appearance. It comes with two 80-mm fans, one right here and there is a green LED fan right here.
Now something very unique to this product is the three adjustable rails. You could adjust the +12V, +5V and the +3.3V manually here at the top. Also right here is the on/off switch and the power cable gets connected right here.
Now let us get back to these three adjustable rails. This is called PowerFlex and this feature is for fine tuning, the +12V, +5V and the +3.3V rail and you can do this with a screwdriver. In LED, six below each of these adjustable rails, now a green light indicates it’s within ± 5% of optimal. A yellow light indicates under voltage and the red light indicates over voltage.
This power supply has all kinds of leads and they are all sleeved. But let me first go through the ones which get connected into the motherboard. You have a 24-pin but this is also a 20 pin. You can see how that works. Also right here an 8-pin or a 4-pin.
And there are eight standard 4-pin Molex connectors, six are just like this and there are two shielded ones. There are two Serial ATA, two for the floppy and one shielded for the PCIExpress video card. Now have a look and a listen
As you can see from the results, this power supply does perform very well. It has lots of power and it is loaded full of features. Overall this is kick-ass product.
