5 out of 5 eggsThis is It!

Pros: No noise, None. Plenty of connectors, even legacy 4 pin.

Cons: A bit wider than typical power sources. Had to use more pressure than I thought I should to get it in. A minor issue.

Other Thoughts: Studio PC now dead quiet! Yippee!

Pros: 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 fully 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. Man, now I can day trade in PEACE!

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 buy custom 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 their review the screw holes do not line up perfectly with standard cases with a side guide rail (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 or cut the small side tab off it is not a rail. If there is no side guide rail, you are good to go as all the holes are otherwise spaced correctly. The power supply stays cool and with a fan pulling even a little air out of the case you will likely have no problems as long as you are using low voltage. (My computer uses only 60 watts so it will probably never get hot). For those of you using high powered video cards with it, I would assume better circulation may be necessary but I have no personal experience with that. The power tests done on benchmark sites show this PSU comes in very good only a little lower than Seasonic ss-520 and Silverstone NightJar (which uses the ss-520 from Seasonic anyways). The paint job is very thick and all a simple color which makes it look extra nice and sleek in cases with windows (like mine).

Cons: These are really not deal breakers but to put something here...
-Holes may not line up perfectly in your case, but that is easily solved.
-Tilts down and back instead of sitting flat (because of the slight misalignment of the heatsink panel)
-Not 100% modular
-Has a non modular set of PCI-E cables that are not needed for someone like me... (my personal con I guess)
-Ugly cables that people like me who use modded cables and window cases don't like to look at (I did get them pretty well tucked out of sight I must admit but did we really need to use cheapo looking red and blue plastic ends?) Anyways...

Other Thoughts: Basically, for those of you tired of having the PSU fan be the loudest one in your case and not wanting to break the warranty to switch it out with a Noctua fan (which I have done to those out of warranty), and for those of you who no longer believe the PSU companies when they claim to have "silent fans," and for those of you who have an old very good quality Seasonic x1050w with a Hybrid fan control that you used in a new 60w computer that never turns the fan on under 200w (which is good because the fan is loud) but has a very annoying hissing coil whine that drives you nuts no matter where in the room your computer sits, you need thin flexible cables and a small PSU for a tight fit in a mini itx case, THE ROSEWILL PSU IS PERFECT FOR YOUR NEEDS!

And I will admit, perhaps if I used 500w or 600w there might not be a coil whine, the thing is I did not want to spend another $150 for yet another PSU. Using it in my gaming computer is no big deal since it is full of noisy fans anyways.

Specs for the ultimate non gaming silent small computer: Asus Maximus VII Impact z97 Chipset, 16gb Patriot DDR3 2133, Intel i7 4790s, Noctua NH-L9-i, Zalman Fanmate controller, Rosewill case fan on low, Rosewill U2-S window case, intel 730 240GB SSD, and of course a Rosewill Silentnight 500.

5 out of 5 eggsIt's Silent :D

Pros: Does not make any noise.
Powers a system with a GTX 970 Strix

Cons: If you have a side window on your case you might not like that the PCI-E power cables are red and yellow.

Other Thoughts: My goal with my build was absolute silence and I reached it with the help of this PSU.

Specs: Intel Xeon 3.4-3.8Ghz (i7 4770 minus IGP)
ASUS Z97 Motherboard
12GB DDR3 1600 RAM

5 out of 5 eggsNever going back.

Pros: - Fanless.
- Fanless.
- Fanless.
- Did I mention...fanless? For those in pursuit of the ultimate silent computing experience, I am not entirely sure why you haven't purchased a fanless PSU yet. If you have, then you are in the know. If not, what are you waiting for?
- Seven year warranty.
- Sweet textile pouch with Rosewill badging that holds all the unused cables.
- Comes with rubberized caps that cover unused connections on the unit itself. I like this a lot, it's the small things that get me.
- Efficiency of ~93% between 300W load and up to nearly 400W. This is perfect for 99.999% single GPU solutions these days. Platinum baby!

Cons: - Tad pricey.


- Mounting holes for only one orientation.
- Would've liked black ribbon style cables for non-modular units.
- Employs annoying split connectors (20+4 ATX, 4+4 CPU, 6+2 PCI-E, etc.)
- Multi-colored connectors.

Other Thoughts: - Rebadged Kingwin Styker STR-500. Nothing wrong with that.
- Powers an OC GTX 970 and OC 4690K just fine.
- HEAVY. There is are massive heatsinks inside and out of this unit so this comes as no surprise.
- Since my PSU sits locked away in it's own compartment (Silverstone FT-03) I ended up attaching my own ultra-silent 80mm fan to the rear end of the unit as an exhaust. After being burned time and time again by lousy, ****tastic fans that come with supposedly reputable companies, I finally gave up and looked into fanless solutions. I do not regret my decision!
- PLEASE do research before purchasing a fanless PSU! Just because it is passively cooled, that does not mean it doesn't need any airflow. The reason why this thing has perforated mesh on 5 of its 6 faces is because companies design these things assuming that your case will supply some decent airflow. Take care of your baby!

3 out of 5 eggsWorks well, but only semimodular, and the VOCs...

Pros: No fan, no coil whine, and cables aren't too rigid.

Cons: I would have liked it more if it were fully modular, rather than only partly. The 12V/P4 connector, especially, is one that should not be integrated, to make routing easier.

The really bad part, though, are the fumes. A premium part like this should have those under control, or at least be packaged so that it can vent between the factory and your home.

Other Thoughts: If you already have a quiet PC, want that last step, and also want to avoid the Seasonic noises, it's hard to wrong for the cost.

5 out of 5 eggsAs silent as it gets

Pros: Completely silent, no noise, nada. It's great. Has plenty of modular connections if needed. I use it for my home server, so mostly it's just HDD's, so it doesn't use most of its power. But, no problems and the Newegg rebate made the price even better. Hasn't run hot at all.

Cons: None

5 out of 5 eggsA truly silent PSU

Pros: -Absolute silence. I went and stuck my head next to my PSU albeit under very little load and I couldn't hear a thing.

-Looks good and it comes in all black, the cables are decently sleeved too to hide those nasty coloured cables.

-It performs like a 500w PSU but it can act as a 600w power supply too.

I use this in my PC with a reference EVGA SC 780 and an i5 2500k, both at stock clock speeds. I've never had an issue with power.

Cons: -I would have liked the whole PSU to be modular but the only non-modular cables are the 24 pin, cpu power and one 2x 6+2 pin pci express power. Not really a bad thing since these cables cover all your bases if you plan to build a PC with a dedicated graphic card. Not going to deduct an egg for it.

-Price is a bit high on this PSU but you do get what you pay for, high quality silent operation and a sleek look to go with it.

-You won't be able to SLI (unless you're running some really low power GPUs) with this PSU, but that's a given considering this is a 500-600w PSU.

Other Thoughts: Probably the best PSU I've ever bought, I'd buy another one if I were going to build another PC in the future

5 out of 5 eggsNice and Quiet

Pros: Plenty of power for home server application. so it's not powering a lot of stuff. just a couple hdd that aren't always going full bore, a couple case fans and the cpu/mb. heat dissipates well. That's as much a function of the case, I suppose, but it takes two to tango. I'm very happy with this. Had the rig on 24/7 for a few weeks. temps are good.

Cons: more power options/output would be nice, but passive cooling has a price.

Other Thoughts: I bought some standard 120mm case fans to go with this because they were rated well (quiet) by newegg users. it was a mistake. I should have ponied up a few more bucks for fluid bearing fans. but that's no reflection on this PSU. :-)

5 out of 5 eggsFanless = DEAD SILENT

Pros: - I can't hear anything!
- Plenty of cables for your peripherals
- has a rough-metal feel
- tiny bag included? I guess that's neat.
- The heat sink never gets warmer than your hand. (I do know that depends on your load, but for me its never hot.)

Cons: - only 500W, but for a system that's pulling an average of 40W, that overhead leaves room for expansion

Other Thoughts: Seriously, why aren't there more fanless PSUs for sale?

Fanless PSUs are far superior to any LED flashing, whirlwind creating, dust magnet, PSU out there.
