1000W Redundant 1U Server Power Supply

This 1000 watt redundant power supply fits a 1U server chassis and delivers up to 83 amps on the +12 volt rail. It accepts a universal 88 to 264 volt input at 47 to 63 hertz and is rated for 100,000 hours MTBF at 25 degrees Celsius. The unit weighs 10.00 lbs and measures 1.63 by 4.17 by 15.75 inches.

Who This Suits and Who Should Look Elsewhere

It suits administrators building or repairing a redundant server platform that requires dual EPS 12V 8-pin connectors and PCIe 6+2 pin power for add-in cards. Buyers who need higher total output or a non-redundant single-module design should look elsewhere.

Deciding Specification — Connector Complement

The fixed cable set includes one ATX 24-pin, one P4 4-pin, two EPS 8-pin, two PCIe 6+2-pin, three SATA 15-pin and three Molex 4-pin connectors. Verify that this exact combination matches the motherboard and drive configuration before purchase.

Questions about this item

How much heat and noise does the 1000W redundant unit produce when running continuously at full load?

The supply is rated for 0°C to 50°C operating temperature at full load with an MTBF of 100,000 hours at 25°C, indicating sustained thermal performance.

What existing server chassis and cabling are required to install this 1U redundant power supply?

It fits a standard 1U rack bay measuring 1.63" x 4.17" x 15.75" and connects via a 24-pin ATX, one 4-pin P4, two 8-pin EPS, two 6+2-pin PCIe, three SATA and three Molex leads.

Will this power supply work with older motherboards that only have a 20-pin main connector and 4-pin CPU power?

Yes, the 24-pin ATX connector splits into 20+4 pins and the two 8-pin EPS connectors each separate into 4+4 pins for legacy boards.
