Server power supply for 1U rack builds
The Seasonic SS-500L1U is a new 500W EPS12V unit built for single 1U server installations. It delivers +12V at 40A with +3.3V and +5V each at 20A for balanced rail loading. Active PFC and a DC-to-DC converter design keep efficiency above 87 percent at typical loads.
Practical limits of the EPS12V standard
The form factor measures 235 by 100 by 40mm and fits a single 1U slot with an input range of 47 to 63 Hz. Modular cables are customised for the chassis rather than following a universal pinout, so cable routing must match the server layout. MTBF exceeds 100000 hours with protections for short circuit, over voltage and over power.
Upgrade from lower-efficiency or failed units
Replacing an older supply that lacks 80PLUS Gold certification cuts waste heat and improves rail stability under sustained loads. The jump is worth it when the existing unit shows ripple above one percent or when fan noise becomes intrusive in a quiet rack. Builders needing redundant power or higher wattage should look elsewhere.

Ερωτήσεις για αυτό το προϊόν
Is this the only capacity available for the SS-500L1U?
The SS-500L1U is offered as a single 500W model with no alternative wattage versions listed.
What does the 500W rating mean for my server build?
It delivers up to 500W total, with the +12V rail supplying a combined 40A for CPU and GPU power.
Does the EPS12V interface limit the 500W output in any way?
The EPS12V design supports the full 500W across all rails, with Active PFC correcting the power factor to 99% typical.
