By now, most members of OCC should appreciate the importance of using a good quality power supply. Low end generics certainly have their uses and most will safely power a basic office/internet PC for years, but as far as the computer enthusiast is concerned ,that's really where their usefulness should end. Low end generic power supplies usually lack one or all of the following features:
- Sufficient filtering on the AC mains input, if at all.
- Safety features like OVP, OCP, short circuit protection, etc.
- Power factor correction.
- High efficiency.
- Realistic operating temperature.
Why risk hundreds of dollars worth of high end hardware by installing a poor quality generic power supply? You don't have to spend hundreds of dollars on a power supply and a little time spent on Google can pay dividends. There are numerous power supplies of acceptable quality at or around fifty to sixty dollars and many sites have frequent special offers and "deal of the day" promotions; you just have to find them!
A good quality power supply is essential. It will cost less to run, not to mention provide the good quality, stable rails needed for today's high end gaming and overclocked rigs.
The Xigmatek NRP-PC402 can be had for as little as £40.00 in the UK. So is it a high-priced "generic" or a good quality, entry level power supply? That's what we're here to find out.
Xigmatek Co Ltd was founded in 2005, making them relatively new to the market, with its R&D based in Germany and manufacturing in China. Specializing in cooling solutions, the company also offer a range of computer power supplies aimed at the enthusiast. This time, I am going to take a look at the Xigmatek NRP-PC402 400W "green" power supply and see how it performs.
"NRP-PC402, the latest Xigmatek high efficiency and eco-friendly power supply not only boots up your PC but makes efforts for our mother Earth. NRP-PC402 is the first Xigmatek 80Plus Bronze certified power supply up to 85% AC-DC switching efficiency with 0.99 active PF rate but we do more than other 80Plus PSU because we use recycled materials for our retail package to avoid felling any tree. If you use NRP-PC402 in your system, you can reduce energy waste, thermal release, your wallet, and CO2 emission, save trees for our Earth. When you are playing games, surfing internet, watching videos, you are saving our green world for your kids. "
No glossy photographs or colorful graphics adorn on this box, and to keep with the "green" theme, the packaging is made from 100% recycled paper. The top of the box further emphasizes this theme by showing a power supply with a forest growing out of it. The 80 Plus Bronze logo is there, along with icons to illustrate the safety and power supply features. The base of the box tells us how much energy/money you can save by installing this power supply when compared against a power supply of 75% efficiency, along with an illustration of the connectors and cable lengths.
The front panel of the box gives a full list of the features and the opposite face shows graphs of percentage loading against noise to illustrate the quietness of the Xigmatek NRP-PC402 power supply.
This box is also used for the 500W version of this power supply, which explains why the specification table for both power supplies is shown on the side panel. The opposite side panel carries a photograph of the power supply along with serial and model number information and barcodes.
Upon opening the box, you'll find a thin sheet of foam on the top and bottom that protect the power supply, which is neatly enclosed in its own black cloth, drawstring bag. The power cord and mounting screws are contained in their own box and all the cables are neatly wrapped with a Velcro strap and stored down the side of the power supply. You'll also find a warranty card and basic user manual.
Basic, but adequately packaged power supply. Let's move on and have a closer look.
