Product Description

High end PSU means high output capability, and therefore high heat generation and high noise level? It's not true when it comes to the Rosewill Silentnight PSU. On top of all the features you would demand on premium grade PSU such as modular cable configuration, generous +12V output and comprehensive protection, the SilentNight-500 employs a fanless design ensuring a complete quiet operation - your games, movies and music come to new life with every whisper and detail enjoyed the way it should be. A large heat sink with dense fins quickly and efficiently dissipate heat, while highly reliable Japanese capacitors and 80 PLUS Platinum Certification for lower heat generation contribute to the enablement of fanless design. Make the Rosewill SilentNight-500 yours today, and step into a new level of peace of mind.

Great PSU, runs silent works perfectly but...

Be careful when plugging in the modular sockets as the plugs fit upside down as well. I blew out my ssd before I realized it was the wrong way up. Seems like something that Rosewill should fix to prevent customers from installing equipment incorrectly.

Work almost silently, very low level singing.
I don't really push the overall power rating because it is for a Audio PC with a minimal video card.
Voltages are stable in mild over-clocking and fairly close to spec.
Excellent heat-sinking keeps temp. under control even in a minimal fan silent PC.
I had a cracked cable connector and the only way to get a new one was to RMA the whole supply because Rosewill has zero spare parts.
Zero downloadable documentation on the Rosewill site as well.
One star off for not caring.

Rosewill's product is called SilentNight for a reason. It operates in complete silence because it comes with no fan. How was this possible? Well the answer must be the excellent design, components and execution they put together. Platinum certified is probably the only PC power supply class that can retain (and thus dissipate as heat) the least amount of 110V input power, while delivering the highest output power to be used by your PC. I had the PC running continuously for a week at variable load without noticing heat coming out of the PSU, which basically remains at room temperature. Curiosity urged me to open up the PSU and admire the engineering, but knowing that would most likely void the warranty I held back.

GREEN-est cleanest energy class PSU you can find today. 500W is plenty enough for a home PC. Do the math if you use multiple power hungry, non-green components to verify your system demands less than 500W. Calculate yourself based on components' specs and add an extra 25% for safety. The generic statement "you need a 1000W PSU" thrown out by some vendors or manufacturers, especially related to video cards is too extreme to be taken seriously. That's why you need to do the math yourself based on your particular system.

If you use a very large (full/extended) PC case the provided cables are still long enough to reach to the CPU and MB, but you may have to run them on top of the MB, not around it; this would only affect the aesthetics, in case you care for it once you closed up the PC case. For normal PC cases the cables are long enough and easy to work with.

Good luck with your design!

Reading reviews, this power supply is identical to the Kingwin STR-500, which by those reviews, is one of the three best power supplies ever made for output power stability and voltage regulation. 500W is more than enough for all but the most extreme computers, so unless you have a high-end SLI setup, the Rosewill has you covered.

Most PC products that claim to be "silent" really need to buy a dictionary for their marketing team.
A component with any spinning fan is not silent, period.
This power supply is exactly that -- truly dead silent. In a quiet room, you can put your ear right up to it and hear nothing.

While advertised as 500W, it will actually output 600W, just at 80+ Gold efficiency once you get past 500W. 600W is enough for almost any PC. You can run a top of the like i7 processor and two video cards in SLI, as long as the video cards are not extreme energy consumers like the AMD Radeon 290x.

I run a gaming PC with a nVidia 780GTX overclocked video card, an overclocked i7-2600K processor, 32GB of RAM, 4 optical drives, two SSDs, two hard drives, and a half dozen peripherals (throttle, joystick, pedals, TrackIR, etc.) This PSU handles everything with only minor warmth coming from the unit. Of course, when the video card is under stress, its fan noise is louder than many quality fan-cooled power supply units. Remember consider noise from other components when buying your parts.

It is easy to build a completely silent, fanless PC using an SSD for storage, this PSU, and a fanless CPU cooler like the NoFan CR-95C. It only gets tricky when you add in high-end video cards, which typically do not have fanless options available.

NO COIL WHINE!!!!!! NO COIL WHINE!!!!!! NO COIL WHINE!!!!!! For all of you former/current Seasonic users with this issue, you know what I mean. Seasonic makes ultra high quality modular PSUs with great electrical management, but about 1/3 of them have a coil whine problem which can drive a person nuts! I tried every single power saving setting in existence in the BIOS and plugged more things in to use more watts or less things in and it just changed the sound of the coil whine, nothing more.

I am so happy now!!!!!!

Okay, so to actually review it. It is a good small size for small mini itx cases such as the Rosewill Legacy U2 that I have it in. I kind of like fully modular systems so I can mod the cables, but Rosewill did a good job with keeping the covering flexible enough to manipulate and tight enough so as not to be big and bulky. Also, I find it unnecessary to have one set of PCI-E cables not modular when they have all those modular ports for putting stuff but that is fine. I guess someone is going to use a bunch of heavy powered video cards with a fanless 500w PSU... Besides that miniscule annoyance, the flat cables are very easy to use and manipulate for cable management. Make sure you snap the cables in properly as installing it upside down (which some people claimed was possible on the side that connects to the PSU) could fry your SSD. Besides that, as others have noted elsewhere in their review the screw holes do not line up perfectly with standard cases (they seem to all be shifted to one side a bit) so you really have to push the PSU to one side to get them to line up in cases that have a side guide rail. If there is no side guide rail, you are good to go as all the holes are otherwise spaced correctly.
