A Detailed Look
The SilverStone SX700-LPT power supply enclosure is painted with a satin black finish. The power supply measures 130mm deep x 63mm x 125mm. The back panel includes an On-Off switch, AC receptacle and open honey-comb grill.
The power supply features semi-fanless operation (does not spin at lower power loads) and uses a 120mm x 15mm fan made by PowerYear for cooling.
The thirteen blade fan (PY-12015H12S) is rated for 0.22A at 12 VDC and features sleeve bearings for quiet operation. The ultra-quiet fan with intelligent RPM control is designed to provide cool performance and quiet operation.
The front panel on the 700W PSU incorporates eight modular cable connectors, all nicely labelled and color coded. Each blue connector supports a cable with two PCI-E 8/6-pin connectors.
All of the modular cables are flat ribbon-style to assist with neat cable routing and to help maximize airflow. Note that all of the cables are intentionally rather short as this power supply is designed for use in small-size cases.
Under the Hood
Here are a few pictures showing the layout and components inside SX700-LPT power supply. SilverStone is one again using High Power as the OEM for the SFX-L Series 700W PSU. The overall layout, soldering, and build quality all look good.
The power supply features a modern circuit design to meet the 80 Plus criteria for high efficiency and uses DC-to-DC converters on the secondary to produce the +3.3V and +5V rails from the +12V output. All of capacitors used inside the PSU are Japanese made with a mix of solid polymer and electrolytic caps used throughout.
SFX-L seems like such a
SFX-L seems like such a pointless standard, you can get SFX PSUs at 600W, no small system is gonna pull more power than that.
First off, they clearly laid
First off, they clearly laid out the advantages of having a 120mm fan for lower noise.
You also lack imagination. SFX and SFX-L now make ATX sized units seem ridiculously big and unnecessary. Silverstone is coming out with a 800W 80+ Titanium rated SFX-L unit later on this year that could power an overclocked HEDT processor and dual Titan X rig easily (a lot of people over estimate the power needs for a system by a lot).
I have an R9 Nano in an SFF
I have an R9 Nano in an SFF build which has a recommended PSU of 750W.
I bought this PSU for that build. It does just fine, even when the GPU and CPU (which is a 6600K) are both overclocked.
The 450W PSU which I had with the case originally wasn’t enough for the GPU at peak load, let alone with a 95W TDP CPU + overclock. It had two 12V rails. This has one 12V rail with 58A. More than enough.
There’s nothing wrong with meeting the recommended specs *and* having some additional headroom.

i will be running 2x gtx 1080 hybrids off one of these with a i7-6700k all overclocked using every drop of power this thing has to offer
A gem of a review once again.
A gem of a review once again. Why did Silverstone only put a 3 year warranty on this? That makes no sense. It should indeed have at least an 5 year warranty.
I would advise caution when
I would advise caution when buying this PSU do to quality control. I bought one off Amazon for my ITX build, but the PSU would randomly shut off as if the power cord was unplugged. This would happen at random times like while installing Windows, watching Youtube, or just idling. I would have to unplug the power cord from the PSU to be able to restart my PC.
I returned it and bought the SX500-LG and so far it has worked perfectly.
I’m not saying you’re wrong.
I’m not saying you’re wrong. I’m just saying that one faulty OCP circuit does not indicate a QC problem, it indicates one faulty OCP circuit.
There’s a lot of that
There’s a lot of that happening, people are complaining on forums and reviews on neweeg.ca points that same issue, which is very sad. To be fair my corsair sf600 is having the same issues,It has to do with power surges.
There is a bug with the
There is a bug with the semi-fanless mode on the SX700-LPT: The fanless mode is triggered by dropping below a certain power draw only, rather than by power and/or temperature. But the unit still has overtemp protection. This means if the unit is heated up while under low-load conditions, it can become warm enough to trigger overtemp shutdown without the fan ever kicking in!
Whether this is an issue depends on PSU orientation (opening-down = bad), inlet restriction (e.g. fan filters), case airflow (if any), and ambient temperature.
