Hello again, my name is Rodney Reynolds and welcome to another video review. Today, I’m looking at the NZXT Precise 650W Power Supply.
Included in this package are four cable ties, there are five screws for them and an extra one for mounting the power supply in the case, a power cable, a user’s manual and the power supply.
This particular power supply has a continuous wattage of 650 which is certainly enough power for most of today’s 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 the voltages that your computer system can use, and there are essentially two different rails, the 3.3/5-volt rail and the 12-volt rail.
In this particular case the approximate maximum peak output of the 3.3/5volt rail is 170 watts and the 12 volt is 528 watts which is essentially how the wattage of this power supply is determined.
The 3.3/5-volt rail is responsible for the motherboard, memory, PCI cards AGP cards and so on while the 12 volt rail is responsible for the hard drives, DVD, CD ROMs, fans etcetera.
Also some might be interested to know the peak amps on each rail. The +3.3-volt is 24 amps and the + 5volt is 32 amps. Now well, many power supplies still only have one +5 volt rail. This power supply has two and they are both 20 amps.
This power supply meets all the new environmental standards the ATX 12-volt version 2.01 specification and today’s latest testing standards.
Now, there are a couple of important things to not when purchasing a power supply and that is efficiency and doesn’t have active PFC. It’s recommended to get a power supply that’s about 80% efficient or better under a typical load.
Also, APFC or Active Power Factor Correction is something that also assists the power supply in being more efficient and therefore, stable under load.
APFC, basically reduces total harmonics, corrects input voltage and it also allows for full input voltage range. Okay, enough for that techno bubble. Now, let’s have a closer look at the power supply. Right away you’ll notice the high glass paint finished and the 120 millimeter fan.
This blue LED fan will provide ample cooling for the inside of the power supply and there are also lots of ventilation holes. Here is the power switch, power cable connection and the combined LED. This is for the combined power technology. This enables automatic switching between the standard dual +12 volt rails and the combined power of both 12 volt rails.
This power supply has lots of lids. The dual PCI lids which by the way are excellent for in video SLI or ATI CrossFire gaming setups are shielded.
The main 20-20-24 fan motherboard lid has sleeving and the remaining lids are braided. Finally, have and listen to the 120 millimeter fan. This power supply well it doesn’t have any modular lids. It does have efficient power. It’s active PFC. It looks great, has a 120 millimeter fan. It’s quite. It has what’s important in a power in a power supply. Overall, this is a kick ass product.
