Enermax  EG375AX-VE Noisetaker

Testing

To see if this PSU could handle the rodeo burger, we slapped it in our test bed with the most power hungry components I had available, and then added some. Once the machine was powered up, we put it under as much load at one time as we could. With Seti@Home running in the background to put the CPU under load, I transferred the entire contents of a 20GB hard drive to another drive, and then to make things interesting, I threw a DVD into the mix.

Test Bed:

• ABIT IC7-Max3

• Intel P4 3.0GHz 'C'

• Lite-On DVD/CD-RW

• Diabolic Minotaur Case

• 512MB Corsair PC3200

• (2) 20GB Maxtor HDD

• CoolerMaster Aero4 Lite

• (1) 120mm case fan

• (3) 80mm case fans

• Chaintech 5700Ultra

• Windows XP SP1

• ABIT EQ

We used two methods to monitor the voltage. The first was the old fashioned method of plugging in our trusty volt meter, plus we also used ABIT's EQ monitoring software to give you guys a good visual. The two screen shots below record the results at idle and under full system load. 

 

You'll notice the small spikes in the monitor while the system was under load, and when I say small, I mean they were very small fluctuations. Some degree of fluctuation is expected whenever a system begins to pull power. But the size of the fluctuations determines just how stable the power output is, and this Enermax continued to uphold the tradition that Enermax has for strong stable power. The largest fluctuation recorded was less than .9 volts for the 12V line while under load. For the 5V the fluctuation hovered around .03 while under the 3 volt line we recorded only .02 fluctuation.

The Enermax Noisetaker certainly lives up to it's name. This is without a doubt, the quietest power supply I have seen. I unplugged the fans one at a time while the system was running (including the heatsink fan, don't' try THAT one at home) until only the OTES fan was running, and I still could barely hear the PSU fans running. 

Conclusion

To sum things up, this is one kicking power supply. Not only does it supply very stable power to all of your components, but it does so very quietly. The only drawbacks I see to this unit was the stiffness of the cabling, and the size of the PSU. Being only 370 watts, I would personally opt for a larger unit. With the power needs of the Intel Prescott CPU, I would definitely use a larger PSU. But the great thing is that Enermax also makes this same PSU in larger wattages, all the way up whopping 600W version. Now that is some serious power that even Scotty couldn't complain about.

Pros:

• Price

• Quiet

• Very stable power

• Separate 12V rails for clean power to devices

• Dual control fans

• Smart Fan

• Included SATA connectors

Cons:

• Wattage size

• Stiffness of cabling
