Power supply
●
600W Gold, 90% efficient, wide-ranging, active Power Factor Correction, two
auxiliary dongles on two separate 12V rails, ERP 0.5W, Built-in-Self Test (BIST)
Memory technology
●
Dual in-line memory modules (DIMMs) based on DDR3 1600 MHz technology
●
Error checking and correcting (ECC)-protected
●
Four direct-attach memory channels enable low-latency access and fast data transfer
for improved performance
●
