400 W single server supply

The Sparkle Power SPI400W7BB is a 400 W single unit built to the ATX12V and EPS12V standards for rack servers and workstations. It accepts a universal 90–264 V input at 47–63 Hz and fits a 2U form factor with 200x100x70 mm dimensions. The supply targets integrators who need a straightforward, non-redundant power source for standard server boards.

Capacity and headroom

The +12 V rails each deliver 16 A while the +5 V and +3.3 V rails combine for a maximum of 140 W. Peak output reaches 400 W, so configurations drawing near that limit on the 12 V lines will leave little margin for additional drives or expansion cards. Systems with multiple high-draw GPUs or large drive arrays would exceed the available headroom.

Thermals noise and power draw

An internal 12 V DC fan cools the unit across an operating range of 0–50 °C at up to 85 % humidity. Efficiency exceeds 85 % under typical loads, and active PFC meets EN61000-3-2 with input current of 6.3 A at 115 V or 3.0 A at 230 V. Hold-up time is at least 16 ms, and MTBF is rated at 100,000 hours at 25 °C full load.

Questions about this item

Will the SPI400W7BB fit and power my older ATX12V or EPS12V server board?

The unit complies with ATX12V and EPS12V standards and delivers up to 400W through +3.3V@18A, +5V@20A, dual +12V rails at 16A each, -12V@0.5A and +5VSB@2A.

How can I confirm the SPI400W7BB is running correctly once installed?

The internal 12V DC fan spins up on power-on, the unit meets >85% efficiency with active PFC, hold-up time is 16ms minimum, rise time is under 20ms, and leakage current stays below 3.5mA at 264Vac.

What comes with the SPI400W7BB and what must I source separately?

The 2U form-factor supply measuring 200x100x70mm ships with the installed 12V DC fan and a standard IEC C14 inlet for your AC cord; mounting screws and the mains cable are not included.
