Performance, Performance Per Dollar And Noise Ratings
The following chart shows the total performance rating of the PSU, comparing it to other units we have tested. To be more specific, the tested unit is shown as 100 percent, and every other unit's performance is shown relative to it.Click Here To See More Products.
Thanks to its good ripple suppression, the VPF650 takes the lead from the rest of the Bronze-rated units we compared it to, with the exception of the CM G550M. On top of that, we shouldn't forget that this PSU uses high-quality capacitors, which allows it to retain good performance over time.
Performance Per Dollar
The following chart may be the most interesting to many of you because it depicts the unit's performance-per-dollar score. We looked up the current price of each PSU on popular online shops and used those prices and all relative performance numbers to calculate the index. If the specific unit wasn't available in the United States, we searched for it in popular European Union shops, converting the listed price to USD (without VAT). Note that all of the numbers in the following graph are normalized by the rated power of each PSU. Click Here To See More Products.
Strangely enough, in the U.S. market, Antec’s EarthWatts Green (EA-650) costs more than the VPF650 does in the E.U. For most PSUs, this is usually the other way around. Still, even with a $75 price tag, the VPF650 achieves a high performance-per-dollar score that's close to the scores of other Bronze-rated units. Xigmatek's PSU is the only exception.
The chart below depicts the cooling fan's average noise over the PSU's entire operating range, with an ambient temperature between 28 and 30 °C (82 to 86 °F).Click Here To See More Products.
In the noise output area, the Antec VPF650 is a lousy performer. Its overall noise exceeded 43 dB(A). Clearly, you cannot have it all—budget price, good performance, reliability and low noise output. So, if you want a silent PSU, you better look for a higher efficiency rating. You'll just have to pay more for it.
