THE TVS-873E INTERIOR

To access the interior of the TVS-873E you will need to remove the 3 rear screws holding it in place.

QNAP has used a 250W switching power supply unit by Delta Electronics to power the TVS-873E.

Here we see the two PCIe 3.0 x4 slots and a temperature sensor located right in the middle (here you can mount 10GbE, M.2 SSD and WiFi PCIe cards).

Unlike other models you will need a small screwdriver to remove the PCI covers.

The sound card placed in the TVS-873E is none other than the ALC262 4-Channel High Definition Audio model featuring two 24-bit stereo DACs and three 20-bit stereo ADCs.

For all the SATA III drives in the TVS-873E QNAP has used the Marvell 88SE9215-NAA2 SATA host controller.

On the right side of the NAS we find the 4 SODIMM slots two of which are used by 2GB modules by Apacer (2400MHz / CL17), the 512MB flash DOM by ADATA, 60mm intake fan and the two M.2 2260/2280 slots with their temperature sensors.

It's been a while since we last checked the SSD cache feature offered by QNAP so to test it out we'll be using the MX500 500GB M.2 2280 SDD by Crucial.

Also since our X540-T2 10GbE card is not compatible with the TVS-873E (faces on the opposite side) QNAP provided us with the brand new X550-T2 10GbE card for this review.
