This review is from: SILVERSTONE SFX ST30SF 300W Small Form Factor 80 PLUS BRONZE Certified Active PFC Semi-Fanless Power Supply

Pros: Fits well in small cases and comes with a mount to fit in larger cases

Cons: Came dead short cables so only really useful in small cases. Over priced rather get a lepa 500w for a few bucks less.

5 out of 5 eggsGreat power supply

This review is from: SILVERSTONE SFX ST30SF 300W Small Form Factor 80 PLUS BRONZE Certified Active PFC Semi-Fanless Power Supply

Pros: Very small,leaves a lot of room in case.comes with adapter to put in atx cases.helps increase air flow.very quite.very stable.I will use these sfx power supplies a lot more I like the extra room in the case.

Cons: Adapter should be same color as power supply.

Other Thoughts: 300 watts may seem small but,I am running a a8-7600 with onboard video and works great.also running crucial ssd and a slim optical in a Silverstone sg05 case and love it.it works great.

5 out of 5 eggsGood choice for HTPC build

This review is from: SILVERSTONE SFX ST30SF 300W Small Form Factor 80 PLUS BRONZE Certified Active PFC Semi-Fanless Power Supply

Pros: For 65w i3-6100 cpu and on board video with SSD, the fan doesn't even need to run, making for a silent build.

Cons: None

Other Thoughts: Was a perfect fit to replace a 220 watt power supply of lower quality that came included with a mini-itx case and had some fan noise.

5 out of 5 eggsNot much to compare to

This review is from: SILVERSTONE SFX ST30SF 300W Small Form Factor 80 PLUS BRONZE Certified Active PFC Semi-Fanless Power Supply

Pros: Its great, 80+ and good price for it.

Cons: None so far

Other Thoughts: There is not a lot of competition in the SFX market, so this is probably the best rout to take. I trusted reliable time proven company.

5 out of 5 eggsGreat power supply

This review is from: SILVERSTONE SFX ST30SF 300W Small Form Factor 80 PLUS BRONZE Certified Active PFC Semi-Fanless Power Supply

Pros: Great power supply, very efficient. Fan doesn't run if the supply isn't warm, and the supply rarely gets warm.

Has enough connectors for small systems but for NAS need to add additional SATA power connectors.

Dropped idle power consumption for my NAS from ~80W to ~52W.

Cons: Only 3 SATA power connectors and two 4pin MOLEX.

4 out of 5 eggsIf you seek top efficiency, look elsewhere

This review is from: SILVERSTONE SFX ST30SF 300W Small Form Factor 80 PLUS BRONZE Certified Active PFC Semi-Fanless Power Supply

Pros: Light, small, cords are long enough, looks good, has been reliable etc.

Cons: I bought this power supply thinking that since my total power load ( at the wall ) was closer to 55w idle, 180w peak, that this would be more efficient than my 3 year old antec earthwatts.

Nope. I've increased my power draw to 60-65wa idle, and i'm sure the peak load has gone up. I'm rather disappointed in this, but i am keeping it in my computer because it is light and small.

5 out of 5 eggsgood psu

This review is from: SILVERSTONE SFX ST30SF 300W Small Form Factor 80 PLUS BRONZE Certified Active PFC Semi-Fanless Power Supply

Pros: smaller factor
fits in 2u rack mounts
supplies enough power for a render node (in my case)

Cons: slightly higher cost

Other Thoughts: this is a good all around power supply unit that i got because of the low wattage, form factor, and so as not to trip a circuit breaker with the most amount of render nodes possible per power socket.

5 out of 5 eggsSilent PSU: Good for office and HTPC

This review is from: SILVERSTONE SFX ST30SF 300W Small Form Factor 80 PLUS BRONZE Certified Active PFC Semi-Fanless Power Supply

Pros: Small, cool (temp), SILENT, great value.

Cons: None so far

Other Thoughts: I do not usually write reviews, but I was so pleased with this product that I thought it was worthy of one. I was very concerned with the noise of the new system that I recently built (an Intel, mITX). The hardest noise making item in the computer to evaluate is the power supply. I went through 10s of reviews, looking for decibel ratings and measurements of so called "quiet PSUs." I am an audiophile and require literal silence in my system (not just "quiet" fans that so often characterize so called "silent" components).
Complete fanless designs (from Seasonic and the like) are extremely high quality, silent but extremely expensive. I did not want to spend that much. The Silverstone, albeit rated for less and a hybrid silence (the fan kicks in if load is too high) is perfect for mini systems. My power requirements are minimum. This unit fits perfect for my needs and is SILENT, which was my biggest concern.
Some reviewers have noted that an electrical hum develops after a few weeks or months. I have owned this for four months and hear no such ring. I have put my ear right up to the unit and detect no electrical hum. I suspect that there is variation in the units and I was fortunate (although I cannot verify this, I have exposure only to my unit).
Great unit for the audiophile and HTPC user looking for a silent power supply for a small system. Excellent choice, cannot recommend it enough.

I have a small 54w Intel process, 64GB SSD, 2TB HDD, Bluray Drive, mITX motherboard, and 1 stick of RAM. Fan never kicks in the PSU, even under load.

3 out of 5 eggsGood product, not always silent

This review is from: SILVERSTONE SFX ST30SF 300W Small Form Factor 80 PLUS BRONZE Certified Active PFC Semi-Fanless Power Supply

Pros: One of only a few low cost, low wattage power supplies options for low power or low noise builds. So far, appears to have very good build quality. Variable fan control can shut its fan off entirely making it silent.

Cons: The variable fan control is not controllable by the user. Although it can run silent, when it is running it is the loudest component of my build. The other issue is that it only rarely runs in silent mode even in a cool room, and when it does go silent, it is almost always is for under one minute, then you clearly hear it turn back on and hear the fan.

Other Thoughts: For a low cost, low power build, this PS will be more than adequate. If you want a silent PC, this PS is not the way to do it.
