SilverStone TechnologySX1000 Platinum, 80 Plus Platinum 1000W Fully Modular SFX-L Power Supply, SX1000-LPT-X V1.1

I write this review after 2 years of heavy use of 500W SFX-L in my Mini-ITX machine.Recently the power supply cable was slightly pulled and not all the way in which caused some blue sparks coming out of the back of the power supply. Like an idiot, it took me a while to process what was happening, and before I knew it I smelled hot copper and the system shut down. It wouldn't boot back up, not even after 20 mins.I assumed the pc died. Either the PSU blew up or the MOBO was fried. But the next day I when I tried to turn it on again, it was working and just like new! Turns out it was some sort of safety mechanism by the the SilverStone PSU that prevented the system from booting if the temperature is too hot and it prevented the system from being fried when it sensed a large electrical discharge.On top of all that, after 2 years and this incident, it still runs smoothly and silently and keeps the system cool.Worth. Every. Penny.**UPDATE**It's 2020, 4 years later, in a hotter climate with worse electrical current and still going strong.

The Silverstone SST-SX700-LPT-USA is a great 700W power supply. Its a completely modular power supply and the cables are easy to work with. I used this particular model in an ITX build paired with a 10700k and 2080 Super graphics card. The power supply was able to handle the power requirements of the cpu and gpu just fine. One thing the buyer needs to note is the fan within the power supply will not spin on turn on. The fan only comes on when a certain temperature is reached within the power supply. So its very silent. And only comes on when I game. But then I can not even hear it. Everything was in the box i needed and came very well packed.

This fully modular power supply is very tolerant of warmer temperatures and as a results rarely needs to operate the fan. In fact when I say rarely, in my case it is pretty much never. I thought perhaps my fan was not working, but it simply does not need to operate within normal operating parameters. I have a Ryzen 3900x, 1080 GPU, four DDR-4 modules, a Vive Wireless adapter, M.2 WiFi, NVME, and SATA SSD running on an Asrock x570m Pro4 motherboard in a Sliger Cerberus case and, even under heavier loads, the power supply fan simply does not need to operate. The only fans I hear running are the CPU and chipset fan. I am extremely happy with the purchase and would more than likely look to purchase this again in a future build. The smaller size of this SFX-L power supply gives me a lot more flexibility in mounting it and has really opened up the space to work inside the case. Due to the extreme flexibility of the Sliger Cerberus (best case I think I have ever purchased) I have the power supply mounted in the front of the case drawing outside air in and exhausting out the top of the case. The natural convection in this orientation assists in the silent operation. If I had to buy another power supply today, I would get this exact same model.

Hi, I want to write my first review on Amazon for this product because it is not like what people commented here or on Reddit last year and it is not noisy now. Maybe they have fixed the issue and updated to a new version (v1.1).Update: Coil whine / squeaking appears for some games. For me, I hear the high-pitch sound when playing Cyberpunk 2077 and Warframe. Other power-intensive games or mining are fine, running without such noises. I got a replacement but still get this sound. Not sure what is the fix cause it only applies to some softwares, but the PSU works fine, the only 1000w SFX! Hope the noise fades away.

So far this power supply has been super solid. No issues after a couple of power outages, and seems to put out consistent power. Easily powers high end hardware with no unexpected shut downs. Only negative I have with this thing is the whining. You can here it depending on the power draw, a high pitch whine coming from it. It doesn't bother me, because I usually have headphones on most of the time, but just something to be aware of. Overall, happy with my purchase. I have always trusted Silverstone power supplies and actually have one 10 years old that's still going strong.

Well, this has been a disappointing product from SilverStone AND the first time I have received sub-par service from Amazon. When paying 2 to 3 times what you would for a typical component you expect something top-notch and trouble free. The whole purpose of this power supply is to provide a larger fan with less noise. The first one I got made a ticking noise when starting up (it cycles on and off based on your system load) and then would occasionally make a moaning noise while it was running. I ordered a replacement after the first day. I received the replacement quickly but I could tell from the beat up packaging that this was most likely also a return that was being shipped out as a replacement for my defective unit. It even had a bracket from a prior system still attached to it. I installed it and once I got the load up to where the power supply would turn on it starting making a whining noise but wouldn't spin. I gave it a little nudge with a screw driver and it started to spin but would again make occasional noises. Needless to say I'm requesting another replacement and will keep doing so until they make it right.
