SilverStone SX1000 1000W SFX-L Power Supply Review

SilverStone SX1000

SilverStoneTek is a company best known for its high-quality cases but its product lines extend into other components such as cooling, power supplies (of various model lines that range from 300W to 1350W in DC output), fans, and storage solutions. SilverStone has built up this impressive product repertoire since its founding in 2003. For this review, we are looking at the SX1000 (model number SST-SX1000-LPT) which is one of SilverStone’s SFX (small form factor)-L products. It is produced in conjunction with Enhance.

Enhance Electronics Co. Ltd. was founded more than 30 years ago in 1986. While a major power supply OEM Enhance is not nearly as well known to most users as some other OEMs as its core business focus has been outside of the desktop market in areas such as servers, embedded, and telecom markets. However, its products have started to surface in the US consumer realm in the last year or so under the likes of SilverStone, Silverpower, Antec, Cooler Master, and GIGABYTE, as well as the occasional Enhance branded model.

10lbs In A 5lb Sack? How About 1000W’s In A SFX-L Sack?

The SilverStone SX1000 is the first SFX-L unit we have seen from SilverStone. However, we have seen three standard SFX units from SilverStone before here at TheFPSReview. So, while we have seen small units with huge capacities from SilverStone before, we have not seen this slightly larger SFX-L form factor before.

This particular unit is probably a bit more interesting than the most recent SFX unit we saw from SilverStone on that basis alone. However, there is a second big surprise from this unit; 1000W of power! Now, since this product is coming to us from what is SilverStone’s wheelhouse, we have great expectations from this tiny power supply and what SilverStone can wring out of it. However, before we get too far ahead of ourselves, let’s first see what SilverStone has to say about this unit:

■ SFX-L form factor for use in small form-factor computers

■ 1000W continuous power output rated for 24/7 operation

■ Class-leading single +12V rail with 83.3A

■ High efficiency with 80 PLUS Platinum certification

■ Silent running 120mm dual ball bearing fan with advanced semi-fanless operation

■ 100% modular short cables with flexible flat arrays

■ Strict ±3% voltage regulation and low ripple & noise

■ 24/7 continuous power output with 50℃ operating temperature

■ High-quality construction with all Japanese capacitors

If you have never heard of the SFX-L form factor before, this special form factor has a longer depth than SFX power supplies.

Let’s move on now and see what we can expect when a user purchases the SilverStone SX1000 power supply in retail in terms of documentation, accessories, cable count, rail layout, output characteristics, and general build quality.
