PWS-1K43F-1R 1400W redundant server supply

The PWS-1K43F-1R is a 1U form-factor AC-DC unit rated for 1200 W at low-line input and 1400 W at high-line input. It targets administrators upgrading or maintaining validated Supermicro platforms that require hot-swap redundant power with 80 Plus Platinum efficiency.

Installation notes and common issues

The supply slides into a 1U bay and mates through a gold-finger connector; no screw-down cables are needed. Verify the chassis backplane matches the gold-finger pin-out before insertion. A frequent mistake is powering the unit from a 100–140 Vac circuit while expecting 1400 W output — the higher rating only activates at 180–240 Vac.

Pre-order compatibility checks

Confirm the target system appears in the validated list such as SYS-1017GR-TF, SYS-5018GR-T or SYS-8048B-TR4F. Check that the facility can deliver 180–240 Vac at up to 10.5 A for full 1400 W operation. Ensure the rack provides a 1U slot with 298 mm depth clearance for the 298 x 40.4 x 104.5 mm enclosure.

What comes with the PWS-1K43F-1R and what must I source separately?

The supply itself with gold-finger output and 5V standby at 6.0A; you must provide compatible server chassis rails and AC cables rated for 14.7A at 100-140Vac or 10.5A at 180-240Vac.
