SilverStone SX1000 adalah satu-satunya dari jenisnya sejauh ini, sehingga dengan mudah mengambil mahkota dalam kategori SFX-L berkapasitas tinggi, dan akan disertakan dalam artikel pilihan PSU terbaik. Jika Anda membutuhkan catu daya super kuat namun ringkas, Anda harus memperhatikan SX1000 dengan baik. Ini dapat dengan mudah mendukung sistem permainan yang kuat tanpa kompromi, dan selama Anda menjaga beban di bawah 700W, output kebisingannya tidak akan mengganggu Anda kecuali Anda sangat sensitif. Satu-satunya, utama, downside adalah harga tinggi, yang di pasar AS melebihi 300 dolar.

Silverstone baru-baru ini memperkenalkan lini SX PSU-nya, yang terdiri dari dua unit SFX-L dengan kapasitas 750W dan 1000W. Sangat mengesankan melihat PSU berdimensi kompak menghasilkan begitu banyak tenaga. SX1000 memiliki kerapatan daya 969W per liter, yang merupakan salah satu yang tertinggi yang pernah kami lihat sejauh ini. Untuk memastikannya dapat memberikan kekuatan penuhnya tanpa masalah, Silverstone melengkapinya dengan dua konektor EPS dan enam PCIe. Untungnya, semua kabel sepenuhnya modular, jadi Anda hanya dapat menggunakan kabel yang Anda butuhkan.

Because of the high power density the temperatures at the internals will be high, so Silverstone decided to go with a double ball-bearing fan, which might be noisier than a similar spec FDB fan, but it is able to withstand much higher operating temperatures, without sweating. Besides capacitors, the cooling fan is among the most important parts inside a power supply, so you should pay great attention to its quality. If the fan fails early, the PSU will get high stress and it can even fail, if there is no over temperature protection.

There are plenty of cables and connectors, including two EPS, six PCIe, and eight SATA connectors. There is even a Berg connector, which should be replaced though with a 4-pin Molex. Very few users need a Berg/FDD connector, and the ones who need it can get an adapter. So why waste a 4-pin Molex for a rarely used FDD connector. 

Cable length is short since this is a small form factor PSU, destined for an equally small chassis. Nonetheless, the distance between the peripheral connectors is impressively long, showing that Silverstone took into account any possible cable management and root issues.

The platform’s design is interesting and clean, despite the high power density. Enhance Electronics, the OEM, used quite large heat sinks on the primary side, with perforations on the APFC heat sink to allow airflow to the components installed below it. In addition, there are two main transformers, installed in parallel, to handle the unit’s increased power output. 

It is impressive to see a full-bridge design in a small form factor power supply. An LLC resonant converter is also used for higher efficiency. We find synchronous rectification for the +12V rail on the secondary side, and the minor rails are generated through a pair of DC-DC converters.

The first part of the EMI filter is on the AC receptacle and consists of two Y caps. The second part, on the main PCB, includes two Y and four X caps and a pair of CM chokes. There is also an MOV for protection against voltage surges. The unit’s large inrush currents are suppressed by an NTC thermistor and bypass relay combo. 

SilverStone SX1000 Bridge Rectifier

The PSU uses a single bridge rectifier which was impossible to identify without completely removing the heat sink that it was bolted on. So we left this fight for another time.

The APFC converter uses two Infineon FETs and a single boost diode (USCi UJ3D06520TS), among the strongest we have seen so far. The bulk caps are by Rubycon, and their combined capacity is high at 940uF. Finally, the APFC controller is an AT6103ZSPC IC.

The main FETs are arranged into a full-bridge topology. An LLC resonant converter is also used to boost efficiency. The LLC resonant controller is an AT6301ZTSF IC.

Eight FETs regulate the +12V rail, and four FETs handle the minor rails. Infineon provides all, so they are of high quality. The common PWM controller for the DC-DC converters is a uPI Semi uP3861P IC.

There aren’t many electrolytic caps on the secondary side, but the ones that Enhance used are of high quality. Lastly, the increased number of polymer caps is by Unicon.
