Bij AnandTech is een vergelijkende test verschenen tussen een viertal voedingen. Getest worden de Antec 430W TruePower, de Vantec 420W Aluminum Stealth, de ThermalTake 420W Silent Purepower en de Enermax 460W voedingen. Gekeken wordt er naar de features, de voltagefluctuaties, de koeling en de geluidsproductie. Over het algemeen komt de voeding van Antec het beste uit de bus. Hij produceert weinig geluid, levert een stabiel voltage en is daarnaast ook nog eens het goedkoopste. Een goede tweede is de Enermax voeding. Deze voeding is wel iets duurder, maar heeft bijvoorbeeld wel de mogelijkheid om de snelheid van de ventilator handmatig in te stellen. Over de Vantac en ThermalTake voedingen is de reviewer iets minder positief:
Even though Vantec's Stealth supply has been generating a lot of hype, we were only mildly impressed with the unit. The presence of three fans might have made the unit a tad too loud. As we mentioned earlier, these fans generated positive pressure inside the unit, which resulted in a general increase in noise levels as air was trapped inside the housing. Furthermore, the line purity on the 3 main rails did not impress us at all; we found instances where interference peaked at 60mv along the +5V rail. For the 110USD, we expected a little more. We were very pleased that Vantec actively worked with us to clear up the issue about the misprint on the unit itself.
ThermalTake's Purepower ended up providing fairly decent performance, but not a lot of features. The performance benchmarks only put the Purepower ahead of Vatec, but Enermax and Antec were tough competitors. Since ThermalTake has been doing a great job of producing themselves as a competitor in the HSF market, we are fairly certain they are here to stay in the PSU market as well. We are very excited to see some of their future offerings.
