A Look Inside

Taking the TVS-472XT apart is not hard as long as you shoot some photos of which screw and part goes where.


This is the disassembled NAS on our photo-shooting bench.


This huge heatsink cools down the CPU and its VRMs. It is supported by a pair of small fans which are installed on a small bracket.


This is the bracket with the two 60 mm fans.


The CPU has enough thermal paste. Right next to the CPU socket are the VRMs that feed it with power.


The unit's flash memory with a capacity of 4 GB.


Both RAM slots are occupied by 2 GB SO-DIMMs.


The Thunderbolt 3 card utilizes an Intel JHL6540 Thunderbolt 3 controller; it was launched in Q2'16 and costs $8.55, so we can't help but wonder why Thunderbolt cards are so expensive.


The SATA expansion card is powered by a 20-pin connector.


The HDDs are cooled down by a Y.S. Tech FD121225LB fan.


A pair of Intel Ethernet controller with model number WGI211AT.


An ITE IT8528E is used on the mainboard.


This is a Lattice LCMX0640C; it is a programmable logic IC and, more specifically, an FPGA (Field Programmable Gate Array) IC.


Here are the two PCIe slots of the mainboard. One is already occupied by the Thunderbolt 3 card.


The power supply is powerful in terms of this unit's needs and of high quality since it is made by Delta Electronics, one of the best PSU manufacturers around. Its model number is DPS-250AB, and it can deliver up to 250 W of power.
