Streacom nano Power Supplies

The Streacom nano power supplies are 100% silent fanless DC-DC solution. No fans, no noise, just power for small and silent PCs.


  1. Very small, can built into ultra-compact PC enclosures and slim server enclosures
  2. Fits any motherboard equipped with 24pin ATX connector
  3. 100% silent, fanless, no moving parts
  4. Highly efficient design, does not produce a lot of heat
  5. Ideal for Intel processors as VIA C7/nano or AMD motherboards

Designed to provide silent ATX power in impossibly small spaces, the Streacom nanoPSUs are designed to fit perfectly into all Streacom cases but can also be used as a silent PSU solution for any case.

Here is our recommendation regarding which PSU to choose. If the system contains a motherboard, CPU (65W max), a SSD/HDD and an optical drive (or another SSD/HDD) then the 120W version would be more than adequate. If the system has more than one SSD/HDD and an optical drive then it is wiser to opt for the 160W version. Whichever one you choose these are the best power supplies currently available able to power a low wattage system in a tiny space.

160W nanoPSU
120W nanoPSU

So far pretty good


I bought this for my mini itx build that I am creating and while I don't have all the parts, I plugged this into my main desktop without the gpu installed and everything powered up.

I am so glad they support the regular IEC cable because it ships with it looks like a UK plug, while I am located in the US. So I just switched them out without a problem.

Nice and quiet (edit: updated review after six months)


My rig:

ASRock FM2A88x-ITX+

AMD A10-7800 (65W)

Thermalright AXP-200 Muscle (with Noctua NF-F12 PWM)

G.Skill Ares 2x4GB DDR3-2133 CL9

Samsung 850 Evo 250GB SSD 2.5"

Raidmax Atomic (mini-ITX case)

NEW: Gigabyte RX 460


Everything works ok.

The power brick stays surprisingly cool. Initially my system drew 40W on idle, and 85W under heavy load (gaming). After purchasing a Gigabyte RX 460, it drew 160W on load. Too close for comfort, so downclocked the RX a bit, and with a ~10% performance hit, I'm now drawing 140W under load, everything is good.


Not really an issue, but rather an inconvenience: the power brick's green LED wouldn't need to be so bright, or at least it could dim down when the computer is off. I think I'll have to put a sticker on top of it, or something...

A simple solid cover for the case's PSU opening would have been a cheap but useful addon. I used an old PCI slot ventilation bracket to screw the power connector into. Which would be another cheap addon. But considering these are tailored more towards the DIY cases (or otherwise more custom cases), this omission was understandable.

But in any case, those are minor details. No major issues so far, six months behind. (Though check the "Other notions")


All in all, it is indeed quite expensive. I can imagine Streacom making a nice margin on these. You could get a pretty high end regular ATX PSU for this cost. But, it's a niche product and Streacom is focused on premium products, and unless the competing manufacturers suddenly see miniature PSUs as a more viable market, then there's not much of a chance of Streacom lowering their prices in the future, either...

Other notions:

There was ALMOST an incompatibility issue with my motherboard. The problem was that the PSU's wires protruded straight towards the RAM sticks. Fortunately, I had fairly low-profile RAM sticks, so it just barely clears out.

From what I've gathered, AsRock is the only FM2+ ITX board manufacturer that places the RAM slot and ATX 24pin header so close and parallel to each other. All the other manufacturers have either the WiFi/BT card or some capacitors next to the ATX 24pin header.

But this will probably be an even bigger issue with Intel-based ITX boards, where it's VERY common to have the RAM slot and ATX 24pin header close and parallel to each other.

In other words, if you're using RAM sticks with bigger heatspreaders, always check your ATX 24pin header and RAM slots

Superb product


I bought this for a low-power storage server based around a Supermicro X10SDV-2C-TLN2F motherboard. I was a bit nervous as I had read some reports of Supermicro boards being a bit fussy about what PSUs they support, and I read an article where someone had some issues using SMC board with a PicoPSU, but with this Streacom product it worked perfectly first time. Very impressed. Completely silent and no heat inside the case. I had to source a PSU blanking plate from eBay, but no issues there.

great PSU for low power system


Simple PSU, fanless, seems very efficient (previous quality 500W PSU that should have been running at ~88% efficient drew 19W at the wall, this draws ~16W on the same setup - system is running a CPU @ 20W TDP, not stressing it yet).

Easy to fit - not really much scope to go wrong here.

An incorrect mains cable was included(?) but the power brick takes a standard PSU kettle lead so have a few spares. You may need to allow for an ATX blank plate depending on your case, don't think QuietPC sells them but not too hard to find in the UK.
