5 out of 5 eggsbig quiet power

Pros: HUGE for passive power pc builds.
If you want a smoking HD video freak-station, like i have, and you don't want to hear a 747 in your living room, get this monster and be happy.

I run a 4x128g SSD raid-0 in my pc so I didn't need the 800-1200w power supply that the noisy "spinner" drives require. but i do have a massive fanless video card that needed 200w of it's own - problem solved with this bad boy!

5 out of 5 eggsSame as Rosewill SilentNight-500 ?

Pros: I do not own this Kingwin Stryker STR-500, BUT, just for the info, it appears to be the same as Rosewill SilentNight-500.

I own two of the Rosewill SilentNight-500 and I like them.

Cons: None.

Other Thoughts: When using a fanless PSU, always make sure all of the radiated heat from the PSU gets directly out of the computer case. The lowest cost way of doing this is to always make sure the case fan(s) blow air from outside the computer case direcrly into the case. Never, have fans "sucking" air out of the case, because, this will pull outside air into the fanless PSU and dump the heat inside ther case.

I do my fanless PSU setups a little different. I always locate the PSU in a separate chamber inside the computer case. I install a super-quiet, low-volume air flow fan to blow the heat out the back. This arrangement cost more, but, it results in the quietest setup, plus, I know 100% for sure all the heat radiated from the PSU gets directly out of the case. Some may say, why buy a fanless PSU if you are going to use a fan to blow the heat outside? Answer: None of the PSUs with fans are as quiet as the fan I use, plus, fanless PSUs are better designed to conduct & radiate heat away from the internal components.

Cost is not a factor with my designs, it is 100% about getting all of the heat directly out of the case with the lowest sound level.

5 out of 5 eggsTotal silence

Pros: - Silent PSU. My case fans is now the loudest component of my PC.
- It has connectors for two videocards.
- Modular connectors.
- It doesn't get hot even after many hours of usage. Though I will test it when I have time to play graphics intense games.
- Probably one of the best totally silent PSU out there.
- This is 80 plus certified PSU.

Cons: - Kind of heacy due to large heatsink.
- Price is still high, but you get what you paid for.
- For that price, maybe it should come with different color LED which you can switch on or off, like Corsair Gxxx series.

Other Thoughts: This PSU being totally silent with no fan at all, chances are it may need air flow coming from the PC case itself. For example, in my HAF922 I have the PSU at the bottom with 200mm intake fan cooling the hard disks and some air will also flow towards the PSU.
Then I have GTX285 videocard with updated fans pointing at the PSU below.
And last there is another 200mm fan on top of case for blowing out the hot air. Although even with heavy usage my system doesn't get very hot, just warm.

5 out of 5 eggsKingwin 500 watt fanless works great!

Pros: It's running two MSI R7870 Hawk CrossfireX video cards very well. Stealthily silent and runs fairly cool, even while running BOINC at 100% stress. So far, I'm very pleased with this PSU. It provides sufficient power for the AMD FX-6300 Six-Core CPU (and two CrossfireX cards). Also running 16 Gigs of RAM.

Cons: None.

Other Thoughts: It's an excellent addition to my fanless computer!

2 out of 5 eggsDied After 9 Months

Pros: It's silent, modular, and super efficient.

Cons: Mine died after about 9 months. I started noticing "random" reboots while my computer wasn't even in use with nothing in the Event Logs to indicate software/driver issues. The reboots became more frequent and while stress testing to try and pinpoint the problem, the power supply tripped my motherboard's surge protection feature.

Other Thoughts: I don't assume that my case is typical, but it's really annoying when a piece of hardware dies like this. I'm going to have to take my entire computer apart and redo all the cabling due to this failure.

I am RMA'ing the power supply with Kingwin (5 year warranties are nice!), but I will probably just sell the replacement and use a new PSU I just ordered.

5 out of 5 eggsForget the rest and buy THE BEST

Pros: Totally silent, designed beautiful, nice box and package, it's silent, runs cool as a cucumber, no fan to suck in dust. Nice silicone covers are used to cover the unused modular ports.

Cons: Not totally modular as the PCI-E cable is hard wired. Guess they figured most people use it so there's no reason to make it a separate cable.

Other Thoughts: They include thumb screws to mount the power supply to the case. Seemed a bit silly to use them, standard case screws are fine, it's not like I'm going to remove the thing on a regular basis.
