SILENT power supply for HTPC

Just bought my new HTPC, now all i need is a power supply. I want something as silent as possible... I heard about fanless power supply but i'm not sure if it is a good idea (overheating on high use?) and if it would be enough for my computer...

Other choice would be a SILENT power supply with only 1 fan... i heard about PSU with fans that turns on only when there is a lot of heat, maybe it would be a good idea for me...

The PSU needs to fit in my Antec Fusion Remote case (not the "max" version)


Here is my list of hardware in my HTPC:

Crucial M4 SSD Micron C400 64GB 2.5IN Solid State Disk Flash Drive SATA3 6Gbps

AMD A6-3650 APU W/ AMD Radeon 65XX HD GFX Quad Core Processor Socket FM1 2.6GHZ 4MB 100W

G.SKILL Ripjaws X F3-12800CL9D-4GBXL 4GB 2X2GB DDR3-1600 CL9-9-9-24 Memory

Gigabyte A75M-D2H mATX AMD FM1 A75 2PCI-E16 1PCI-E1 1PCI DDR3 HDMI DVI SATA3 USB 3.0 Motherboard

+ DVD / keyboard / mouse / remote / wireless mini keyboard / bluetooth adapter

I think your case needs a standatd ATX psu.
If so, look to the SeaSonic X series SS-400FL Active PFC F3 400W fanless psu.
Because it is gold rated for efficiency, it really needs little cooling.

Even the other gold rated seasonics have a fan controller that does not turn on the fan untill it gets a relatively heavy load.
You really don't need a strong psu unless you have a strong graphics card. A stronger gold rated unit with a fan would be the 560w unit:

You can try a FSP gold unit, which costs $71:

FSP is a good budget brand.

A bit off the wall, if you have low power requirements would be something like this:

Or, just get a good, low cost psu like the Corsair builder series 430w for $25 after rebate.
I have used it before, and it really is quiet, but not silent.

Unfortunately the FSP Aurum series is known for having fans which spin too fast. I have read of one person actually changing the fan on his unit because it spins too fast for him.
This is also confirmed by a review at Xbitlabs.

I got tired of replacing Power Supplies in my system. So I stretched for one that I wouldn't have any more problems with.

CORSAIR Gaming Series GS700 700W ATX12V v2.3 80 PLUS Certified Active PFC High Performance Power Supply

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

$99.99 after rebate.
