TP-Link TL-SG108S-M2: the 8-port 2.5G closet default
The roundup says buy an 8-port fanless unmanaged 2.5G. This is that SKU. The letter in the middle matters: buy the S-M2, not the older SG108-M2.
Fanless metal, eight 2.5G ports, 40 Gbps fabric, 29.76 Mpps, 4K MAC, 12 KB jumbo, Cat5e 2.5G. Maker max draw 9.11 W. External 12 V / 1 A brick. 158 × 101 × 25.4 mm. Unmanaged: loop prevention, IGMP snooping, 802.1p. Plug it in. Wall-mount holes in the chassis.
Amazon listing MRP $79.99. pricehistory.app printed $54.99 on 19 Aug 2026. SpecPicks still had $79.49 on 26 Jul 2026. PC Guide logged a June 2026 Prime print at $49.99 against a $129.99 strike. That is sale weather, not a $130 box. Count ports first: 8-port vs 5-port. Five endpoints and a spare: TL-SG105S-M2.
The short list
| Box | What it is | Street, 23 Aug 2026 | Buy if |
|---|---|---|---|
| TP-Link TL-SG108S-M2 | 8× 2.5G, fanless, unmanaged, 40 Gbps, 9.11 W max. ASIN B0CMFX748Y. MFR TL-SG108S-M2 V2. | Amazon $54.99 (19 Aug snap) against $79.99 MRP. Prime-week prints $49.99. Ignore $129 strike-throughs. | The closet default. NAS + desktop + AP backhaul + a couple of 2.5G NICs, and you counted past five. |
| TP-Link TL-SG108-M2 | Older 8× 2.5G sibling. Same job, worse street. ASIN B08ZHZL5Q7. | Often $100–150. Do not buy this because the title also says 8-port 2.5G. | Only if the live S-M2 listing is actually more expensive today. Check the model string on the box photo. |
| TP-Link TL-SG105S-M2 | Five-port sibling. 25 Gbps, 5.81 W. See the 5-port note. | MRP $59.99. Sale street $35–39. | You counted under six and you will not grow this closet this year. |
Skip
Skip the older TL-SG108-M2 when the S-M2 is the $55 box. Skip 8-port toys with two 2.5G uplinks and six leftover 1G ports. Skip SODOLA / HASIVO no-names. Skip a managed Omada PoE chassis until you have APs that need that budget. Skip used 1G Catalyst for this job. If one flow already fills 2.5G, you want SFP+ — that is the 10G uplink note, not this SKU.
