Nexus Releases Silent RX-6500 Modular Power Supply

By - Source: Nexus | B 5 comments

Nexus has released its RX-6500 power supply.

Nexus has announced the RX-6500 power supply. It is a modular power supply with a 650 W maximum power rating. This unit is aimed at users who want a silent experience as well as efficient operation. The silent operation is made possible through the combination of the efficiency and the 135 mm fan. The sound level should always remain below 30 dBA, and at a load up to 50 percent, it shouldn't even go above 20 dBA. This, of course, depends on the room temperature as well as the load.

Nexus claims that the power supply is at least 85 percent efficient, and with a medium-average load, the efficiency is even a bit higher. While Nexus hasn't mentioned any specific 80+ certification, a Dutch webshop, Azerty, has mentioned that it has an 80+ Silver certificate. 

The unit is built with a single 12 V rail and comes with a number of modular cables as well as fixed cables, all of which are sleeved.

So far, there has been no word on pricing or availability, although the unit has a street price of about €90 in Europe.

    According to the 80plus.org website, there's no certification for this PSU at all.

    Any claim by Azerty in regard to its 80-plus rating is bogus without a certified unit on file with 80-Plus.org. Azerty's advertisement is blatantly false. It should remove that claim, and either state the specs supplied by the manufacturer, or test a unit independently and claim that the unit tested within the specs required for whatever 80-Plus rating for which it might qualify. Claiming the unit is 80-Plus Silver is, quite simply, a lie and false advertisement.
    Nexus doesn't claim any 80-Plus certification because it's not certified. There's no mention of an 80-Plus rating at all on its website, but there is a link at the bottom of the unit's description that states "Bronze Certified."

    It's interesting to see a usually quality name mixed up in this kind of false advertising. mess...

    If it has a fan, it isn't silent. What's with this advertorial anyway?

    Under 30 dba is not silent. My modular 80+ Gold PSU would qualify as silent based on their criteria as I'm sure so would many others. Basically any high efficiency PSU with a large well made fan and good air flow should be this quiet. Namely because a high efficiency PSU should produce very little heat as it isn't losing much electricity as heat during conversion from AC to DC.

    I don't think it would be possible to make a silent PSU. Even if there was no fan you would still get the hum of electricity flowing through the components. Though it may not be audible to humans. Your dog and cat would still hear it and you likely could by placing a stethoscope against it.
