Server Power Supply for Multi-GPU Systems

The iStarUSA TC-1200PD8G delivers 1200 watts through an ATX form factor that meets ATX 12V 2.3 and EPS 2.92 specifications. It targets server deployments and high-end workstations that require eight 6+2 pin PCI-E connectors for multiple graphics cards. Modular cabling includes six Molex and ten SATA connectors plus a floppy lead for legacy devices. A 120 mm thermal-controlled ball-bearing fan keeps acoustic output low.

Capacity and Headroom

Rated output reaches 1200 watts with an 80 percent efficiency rating that reduces waste heat and lowers operating cost. The eight PCI-E connectors support multi-GPU configurations while the single 4+4 pin 12V and one 8 pin EPS 12V feed modern motherboards. Over-current, over-voltage and short-circuit protection guard connected components. MTBF exceeds 100,000 hours for continuous operation.

ATX 12V 2.3 and EPS 2.92 Compliance

The unit follows ATX 12V 2.3 and EPS 2.92 standards, so it fits mainstream server chassis and workstation boards that implement those revisions. It does not address newer ATX 3.0 or ATX 3.1 power-excursion requirements that some latest-generation graphics cards demand. Buyers needing the 12VHPWR connector or higher transient response should verify motherboard and GPU compatibility before purchase. Physical dimensions are 3.40 by 5.90 by 7.10 inches.

Questions about this item

Will the 24-pin and dual 4+4-pin 12 V connectors on this 1200 W unit plug straight into an older ATX 2.3 motherboard?

Yes, the supply is ATX 12V 2.3 and EPS 2.92 compliant, so the 24-pin main connector and the 4+4-pin 12 V cable fit legacy boards that follow those specifications.

How can I confirm the 120 mm thermal-controlled fan is running correctly once the PSU is installed?

Listen for the ball-bearing fan spinning at low speed under idle load; the thermal control ramps it up only when internal temperature rises, so quiet operation at rest is normal.

Which cables come pre-attached and which modular leads must I add for a build needing eight GPU power plugs and ten SATA drives?

The unit ships with modular cables including eight 6+2-pin PCI-E leads, six Molex, ten SATA and one floppy connector; attach only the PCI-E and SATA cables your build requires.
