SilverStone SX800-LTI PSU Review

Protection Features

Check out our PSUs 101 article to learn more about PSU protection features.  Our protection features evaluation methodology is described in detail here.

Protection Features
OCP12V: ✗
5V: 35.9A (239.3%)
3.3V: 32.2A (201.3%)
5VSB: 5A (200%)
OPP1024.5W (128.1%)
OTP✓ (180°C @ secondary side)
SCP12V: ✓
5V: ✓
3.3V: ✓
5VSB: ✓
-12V: ✓
PWR_OKDoes not function correctly
NLO
SIPSurge: MOV
Inrush: NTC thermistor & bypass relay

OCP on the minor rails is set high; the same goes for the 5VSB rail.

Over-temperature protection is also set higher than expected. At least all rails are protected against short circuit.

Finally, the power-good signal is inaccurate. That's a great shame for any PSU, especially one that costs so much.

    I know a guy that used to work for SLM at one time in his life. On one of the products for the company brands owned, he could mod it (it was a musical instrument amplifier) for just a couple of pennies and could have saved the company large sums of money on warranty work and improve reliability. He proposed the change, and it was denied because it broke the price-point, and warranties would cover any issues anyway.

    When bean-counters run the show, products will suffer, just so the price-point isn't exceeded and (now days particularly, immediate) profits are maximized. Makes me wonder if Silverstone listened to their bean-counters a little too much.

    The thing I appreciate in SilverStone is that they didn't follow the marketing war in the warranty periods. For me it is really weird to see 10-12 years warranty in PSUs. Now with the mining craziness many companies are trying to find ways to get out of this.

    why did an ad leading to this article popped up automatically on my windows 10 screen? I don't like being spammed, and even less so, when it comes in as sneaky as this.

    It is Tom's way of encouraging you to block ads.

    Adblock+
    Custom Hosts File
    Adguard DNS

    Any of those 3 can make Toms ad free.

    If bean-counters had their way, a PSU like this would have never been released in the first place! It's a very niche product that will not sell in significant quantities. Implementing sleeve bearing fan was not a cost-cutting move, it was out of necessity to keep the PSU noise low for the intended applications. At the time of development, FDB version of this fan was not yet available to us.
