Silverstone Technology ST1300-TI 1300W 80 Plus Titanium server chassis

SKU CH-9KJA-H3Q3K

A 1300W 80 Plus Titanium fully modular power supply with Japanese capacitors, ±3% voltage regulation, and a 135mm semi-fanless fan for 24/7 operation at 50

  • Chassis TypeDesktop
  • Titanium efficiency rating delivers at least 90% conversion even at 10% load
  • Japanese electrolytic capacitors ensure reliable long-term operation under continuous 24/7 use
  • 135mm fan with semi-fanless mode runs silently at low loads
  • Strict ±3% voltage regulation and low ripple provide stable power delivery
  • 1300W continuous output at 50°C ambient supports demanding multi-GPU systems

1300W Titanium power supply for multi-GPU builds

This 1300-watt ATX/PS2 unit carries 80 Plus Titanium certification and delivers continuous output at 50 operating temperature. Japanese electrolytic capacitors and a single +12V rail with ±3% voltage regulation keep ripple and noise low. Fully modular cabling includes dual EPS 8-pin and multiple PCI-E 8/6-pin connectors for dense GPU configurations. The compact chassis fits standard desktop cases without crowding other components.

Replaces lower-efficiency or lower-wattage units

The jump is worthwhile when a system draws sustained heavy loads from several graphics cards for folding, mining, scientific calculation or machine learning. At 10 percent load the supply still exceeds 90 percent conversion efficiency, cutting waste heat and electricity cost over bronze, gold or platinum alternatives. Builders staying with one or two GPUs and lighter workloads will not see the same return on the higher certification tier.

Straightforward ATX installation

Mounting uses standard ATX screw pattern and the fully modular cables plug in only where needed, reducing clutter. The 135mm fan runs silent until internal temperature demands active cooling, then ramps intelligently. Common issues are forgetting the second EPS connector on dual-socket boards or leaving PCI-E daisy-chains unused on high-draw cards, both avoided by checking the connector map before first power-on.

Questions about this item

What form factor and connector layout does the ST1300-TI require for server chassis installation?

The unit follows the PS2 / ATX form factor with fully modular cabling, dual EPS 8-pin connectors and multiple PCI-E 8 / 6-pin leads for direct GPU power.

Which step is most often missed when fitting the 135 mm semi-fanless unit into a tight server chassis?

Installers frequently forget to leave clearance for the intelligent fan curve to spin up at 50 °C, so the fan intake must stay unobstructed.

How do the Japanese electrolytic capacitors affect long-term service intervals in a 24/7 workload?

Japanese capacitors are rated for continuous 24/7 operation at 50 °C, extending replacement cycles well beyond standard designs.
