Specifications
The SX800-LTI power supply is rated for a combined, continuous output power of 800 watts at 40°C (850W peak). The PSU incorporates a single +12V rail that can deliver up to 66A (792W). The PSU includes universal AC line input (automatically adjusts the AC line voltage) and active PFC, which makes the unit more environmentally friendly to the local power grid.

Packaging and Parts
The SilverStone SFX-L Series 800W power supply arrived packed inside a standard retail box showcasing the unit’s features and specifications.
In addition to the power supply, the box contains a power cord, mounting screws, a User Manual, Product Manual, and eight modular cables (plus a 4-pin Molex to HDD adapter).
The flat ribbon-style modular cables handle the power distribution (see table above for lengths and connector count).
I do not quite get it. Who
I do not quite get it. Who needs 800W in SFF PC? 800W is required for top/overclocked SLI or Crossfire configuration only.
Perhaps if Corsair comes out
Perhaps if Corsair comes out with something like the TWO…..which I would do an SLI config on to play on the name or something….
Works well with an ATX
Works well with an ATX adapter and would be perfect in an mATX case (which supports SLI) meaning you have more breathing room. Also, more options is never a bad thing.
So, overclocking your CPU and GPU can tax a PSU, and therefore that extra headroom is good to have.
Finally, it’s Titanium rated. Perhaps they didn’t want to put their best components in a 400W PSU, so they are doing more of a “one size fits many” configuration here.
You just don’t see a lot of good quality PSUs in the lower end of the scale, and that’s in part due to a consumer education issue, but also, it costs more for each SKU you pump out. In other words, it’s an efficiency thing on the manufacturing side as well.
I will buy it, not because I
I will buy it, not because I need that extra wattage, but I need to push the silentness to the limit. With only use 200watt on my ITX, means with 800watt psu, It will be in 40% of its fan envelope, which sometime even the fan still not kicked on. Problem with psu without fan, is the hizzing sound
Quite obvious, the sweet spot
Quite obvious, the sweet spot is 50% usage on a PSU. When you get closer to 100% load, there is a chance that capacitors will pop. Also caps lose capacitance over time. I suppose it won’t matter if you upgrade every year though.
I always enjoy your power
I always enjoy your power supply reviews. Very insightful and thoughtful. It almost seems like Silverstone was trying to cut corners a bit on cost here. Using sleeve bearing fan, and cheap Rubycon capacitors is very unfortunate. I agree they should have used a much higher quality fan, and a much better Japanese capacitor. And that warranty is not good either. Very surprised Silverstone did this. They have always had such a good reputation for quality. An otherwise nice SFX power supply though.
This PSU proves there’s no
This PSU proves there’s no need for ATX PSUs anymore, which saves wasted space. You can run two 1080Ti cards and a high-end CPU from this PSU, which already is quite over the top. With more sensible hardware there’s even a lot of room for overclocking.
Some brands have already started releasing mATX and ATX cases that support SFX PSUs only, like Silverstone, Lian-Li and Thermaltake, with more to come.
