Introduction:

Rosewill may not be the first name you think of when it comes to Power Supplies, but as they've partnered with Newegg, they've certainly made a bit of name for themselves.  What I really appreciate about Rosewill is that they don't release products just for the sake of releasing products.  They release some pretty nice stuff.  Granted, some of it is heavily geared toward the value side of things, but they can and do produce some very decent products.  Their Power Supplies have been one of their products that have helped them stand out from the crowd.  In this segment, they have some 80 PLUS Bronze, Silver and Gold units as well as a few that have earned the distinction of 80 PLUS Platinum.  The Platinum PSU must be no less than 89% efficient at 100% load and 92% efficient at 50% load.  There are a few more distinctions of course, but these are some basics.  For all of the 80 PLUS specifications and information, make sure you check out this link.

Back in February, we looked at their Tachyon 750W 80 PLUS Platinum unit and today we are scaling back the wattage and beefing up the awesome with the SilentNight 80 PLUS Platinum 500W Fanless PSU.  That's right, this power supply has no fan or active cooling at all.  It relies entirely on efficiency and a passive heatsink that also doubles as the top of this unit.  What makes this unit awesome is that it is dead silent - and it still supports four PCIe connections for some dual-graphics card goodness.  Make sure you stay tuned as we take a look, tear into this unit and then torture it to see if it can deliver.

First Impressions:

The Rosewill SilentNight 500W PSU arrived just before I had a major accident that almost cost me my right eye, and it's been on my bench for quite a while and has stood up to months of testing and has been powering a test rig here at BCCHardware.  Often, due to time restraints we don't always get a chance to long-term test products for reliability, but this PSU has stood up very well under pressure.

While the footprint is standard ATX-sized, the PSU feels very hefty thanks to the large aluminum heatsink that provides all of the cooling.  It has a very conservative rating at 500W and many people will think that this PSU will be too small, but my experience with a Core i7-3770K machine and a NVIDIA GTX 660Ti graphics card is that it rarely goes over 290W, which means that this PSU can handle many mainstream gaming systems.  It has a somewhat modular design as you can see below.  Overall the initial quality of the unit is very appealing.  Did I mention that it doesn't have a fan and is totally silent?  Yeah, I guess I did.

The SilentNight comes with a few cables attached as you'll see.  The basic cables that you'll be using with pretty much any system come hard-wired to the box and they include the 20+4-pin motherboard cable, an 4+4-pin CPU cable as well as a couple of 6+2-pin PCIe connectors.  This should help you get going on most systems without having to add many extra cables.  This is a nice touch and I'm glad to see that they didn't also include an extra 8-pin CPU cable with is required for more powerful systems.  If you are using a motherboard that requires that much power, you'll probably want a higher wattage PSU.

On the next page we'll take a close look at the SilentNight 500W and dive into the features, and specifications.
