Server Power Supply for Workstations
The iStarUSA TC-700PD8B is a single 700W unit built for ATX12V and EPS12V platforms. It delivers four independent +12V rails at 16A each alongside +3.3V at 24A and +5V at 30A. The design targets servers and high-end workstations that need steady multi-rail distribution.
Connector Layout and Cooling
A single 80mm fan handles airflow while an active PFC circuit manages input across the full range. The cable set includes one 20+4 pin main connector, one 4+4 pin and one 8 pin EPS 12V, two 6+2 pin PCIe, five Molex, four SATA and one floppy. Over current, over voltage and short-circuit protections are built in.
Upgrade Path and Limits
This unit replaces older supplies that lack dedicated EPS 12V headers or sufficient PCIe connectors for modern add-in cards. The 80% efficiency rating and 100000 hour MTBF suit continuous operation, but builders needing redundant hot-swap modules or higher efficiency certifications should look elsewhere.

Questions about this item
What does the ATX12V / EPS12V standard mean for the 700W output on this unit?
The supply delivers 700W across four +12V rails at 16A each plus 3.3V at 24A and 5V at 30A, meeting ATX12V and EPS12V power-distribution limits.
Will the 5.91" x 3.39" x 5.51" chassis fit a standard PS2 mounting bracket?
Yes, the dimensions match the PS2 form factor used in many server cases, so it mounts with the usual four screws on the rear panel.
Which cables must be connected first to avoid a no-post condition?
Seat the 20+4 pin main connector and the 8-pin EPS 12V cable before powering on; missing the EPS 12V lead is the most common cause of a silent boot.
