Features    [ Edit | History ]

After successfully expanding and leading SFF(small form factor) cases and SFX PSU into the DIY (do it yourself) market, SilverStone engineers have continued their push for advancement in these categories by releasing a true upgrade-worthy small form factor power supply, the ST45SF-G. Despite being half the size of a regular ATX power supply, the ST45SF-G can still produce continuous power output of 450W. Its 80 PLUS Gold level efficiency is a great leap from the previous SFX best of 80 PLUS Bronze and the full modular cables is also the first of its kind for this form factor. To enable users to easily take advantage of this excellent SFX power supply, an adapter is included to convert  ST45SF-G to mount in any ATX case in addition to ones that fit only SFX. For SFF users and for SilverStone, the ST45SF-G is more than just an upgrade, it is an important milestone for DIY desktop computer.

  • Support standard SFX form factor and ATX via included bracket
  • 80 PLUS Gold level efficiency (87%~90% efficiency at 20%~100% loading)
  • 100% modular cables
  • 450W continuous power output at 40? operating temperature rated for 24/7 operation
  • Class-leading single +12V rail with 37A
  • Strict ±3% voltage regulation and low ripple & noise
  • Silent running 80mm fan with 18dBA minimum
  • Single PCI-E 8pin and dual PCI-E 6pin connectors support
  • Active PFC

Pros
- Quiet
- Sufficient current to power a GTX970
- Enough connector cables for all my components. No need to use molex-to-PCIe connectors.
Cons
- Expensive (expected for SFX size)
- SATA power connectors are all on a single cord and depending on what case you have, it might not be possible to connect multiple HDDs without adding extenders due to physical length being insufficient, despite having enough connectors
Summary
I'm downsizing to a mini ITX build (RVZ01 to be specific) and this was a good fit that still provided enough current for a GTX970 plus two SSDs and one HDD.

While expensive (over twice the price of an equivalent ATX model), it gets the job done without being loud or overheating. Hopefully the cost of SFX models in general will go down over time.

Pros
80Plus Gold in a SFX PSU
Cons
Modular cables end up getting in the way
Summary
Had a previous SFX PSU die in my silverstone sugo (SG05B) but the modular plugs cause the cables to stick out the back of the PSU more than a non-modular PSU would. This prevented me from putting one of the brackets back into the case as the cables were in the way. So it fits, but it's more of a squeeze than a non-modular.

Next, also despite being modular, I needed one of each cable, since I needed one molex for the slim DVD drive power adaptor, one sata for the SSD, one PCIE 6pin for the GPU and of course the MB connectors. This one is kind of my fault for not closely looking into that, but the specs don't tell you exactly what peripheral connectors are on what cables.

Aside from this, it's a good high efficiency PSU from a trusted quality brand.

Pros
Quiet, small, decent price point, Gold Standard, modular
Cons
80mm fan, Rounded cables
Summary
Not much to complain about this product. It does what it was meant to do and that's to provide power.

If you're looking for an SFX power supply, this is pretty much the only one that's a Gold Standard. It's fairly quiet as I have version 2.0.

If I had to nit-pick on this, I would have preferred flat cables as working with an ITX setup, rounded cables makes it much more difficult to route the cables. The cables that come with it are fairly rigid making it difficult to work with.

The 80mm fan is decent, but time will tell how it will hold up. I wish it did come with a 92mm fan, but it may have been a space issue with the design.

If you're building an ITX system, this is the only way to go!

Pros
Modular wiring helps reduce clutter. Small size. Relatively low noise but could be better, see cons. Fits in ATX case with supplied adapter.
Cons
Fan is more noisy than it should be during idel useage. NCIX is shipping ver 1.1, while ver 2.0 has supposedly fixed the fan noise problem.
Summary
The model I received had a wire routed into the fan blades causing a terrible noise on power up. Luckily I was able to push the wire out of the way without voiding the warrenty seal, but it means that Silverstone is not testing these units before shipping since there's no way this unit would have passed.

I was dissapointed to receive ver 1.1, it really is more noisy than necessary during idel - see other reviews about this problem. If you buy this power supply, make sure it's ver 2.0 or greater. The noise is faint, but could be annoying for an HTPC build. In another type of build it probably would be silent.

I tooks away 1 star for quality (improper routing of a wire into fan blades) and 1 star for the idel noise levels. Note this is for ver 1.1, ver 2.0 is supposedly better.

Pros
Small, tiny, modular, powerful
Cons
Modular cables are too snug, fan rattles initially
Summary
Got this for a SG05 case and I found that some of the modular cables are so snug that they don't "clip" into the thing they should and just dangle at the edge of it. Beyond that it works perfectly. When I first got it I had issues with the PSU because it made ticks but I shook it and the obtrusive fan noises stopped.

Pros
80+ Gold Rating
Small cables for small cases
Adapter included which allows you to install it in standard ATX power supply cases.
Cons
VERY tight fit in an ft03 mini but it was expected.
Cable sleeving could have been better, but only corsair really gives premium cables with their power supplies so its not a big deal.
Summary
This is the best SFX power supply you can buy. Amazing for mini itx builds.
