OCZ 420watt "ModStream" PSU
Page 3 Performance
Performance of this product will be looked at two ways. One the over all power usage dealing with fluctuations when under idle and load conditions. The second part is temperature and noise level. OCZ has proclaimed to be one the quietest PSU units made and we will see if this is true.
After running this unit for two weeks the first thing we noticed about the noise level is that OCZ pretty much is one of the quieter units available. We have over 15 different PSU units and there were only 3 that feel anywhere near the sound level the Modstream does and two of them are fan less. The problem with the fan less units is they do run a bit hotter making the ModStream a very good solution for noise and keeping it cool. The other unit competing with OCZ is a MGE product using the 120,mm fan as well. The low RPM with large air movement helps make for a silent running PSU. More then once I have heard PSU’s making enormous amounts of noise and OCZ has done a fin job making this quite and cool..
The second part of performance is based on the stability a unit provides this is measured using voltage spikes when put under a series of load and idle test scenarios. Bellow you will see exactly how well OCZ does when giving power to your PC. This is very important to know when picking out a PSU because if you do not have stable power there is a larger chance that the supply will cause damage to your system. I have said this before Wattage is never as important as a solid non fluctuating power source keep it stable and consistent.....
As you can see OCZ does a fine job keeping our PC running at a stable rate with very little power spikes under multiple situations. One of the most amazing parts of our results was the minute voltage fluctuation noted. The ModStream had a maximum movement of any voltage only in the .10 Volts or a 10th of a volt and that was only in the 5 volt and 12 volt. The vcore had a .05 volt variation during tests... You will also note that all the voltages are pretty much in the ideal range making this by far one of the best performing units we have seen to date... It is almost impossible to have a unit not change at all but the ModStream will perform superior to most in the same class. Well worth the extra money spent on this unit over some low end PSU that might cause hardware failures adding up to more money wasted in the future due to drastic voltage spikes...
