If you ended up here because you typed one of those long Tripp Lite part numbers into Google—especially tripp lite p164-000-kpbk8k hdmi keystone coupler—you're probably not looking for a full product review. You're looking for the right answer for your setup. I manage purchasing for a 250-person services company, and I'm the person who writes the POs for this stuff. I've ordered these components for conference rooms, training spaces, and a small network closet. After doing this for a few years, I can tell you: there's no universal answer. There's a right answer for your scenario.
The good news: these problems are easier than the part numbers make them look. Here's how I sort them out.
Four Scenarios, One Brand
The keywords tripp lite vertical rack, C300, UPS, and NXP vs point to four different jobs. Decide which one matches first.
- Wall plate job: You need to pass HDMI through a wall. That's a keystone coupler, not a rack.
- Under-desk job: You have a tower PC taking up floor space. The tool for that is the Tripp Lite C300.
- Rack job: You need power distribution inside a rack. When people search tripp lite vertical rack, they usually mean a vertical PDU.
- Power job: You need backup runtime or PoE. A UPS if you need to survive outages; an NXP injector if you just need to give PoE to a couple devices.
Scenario 1: Wall Plate HDMI — Tripp Lite P164-000-KPBK8K
The Tripp Lite P164-000-KPBK8K HDMI keystone coupler is a simple piece: it turns one HDMI cable into a permanent wall connection. The KPBK8K part means you get eight couplers in one box. I ordered this for a three-display training room and had two left over as spares. So glad I didn't buy a smaller pack—almost did, and would have paid a second shipping charge.
What surprised me: the couplers don't include keystone wall plates or mounting screws. That's a hidden cost nobody mentions. Before you compare prices, ask what's NOT included. A vendor that lists all the accessories up front—even if the total looks higher—usually costs less in the end.
As of January 2025, the P164-000-KPBK8K is listed as an 8-pack HDMI keystone coupler on Tripp Lite's site. Verify current specs before ordering; part numbers occasionally change.
Scenario 2: Under-Desk Tower PC — Tripp Lite C300
The C300 is one of those purchases that feels too simple to matter, until it solves a problem. It's a vertical CPU holder that mounts under a desk. We started using them when staff moved to sit-stand desks and didn't want towers on the floor. The C300 holds the PC vertically, keeps air vents clear, and makes the under-desk area easier to clean. (Mental note: we should have ordered these in the first desk rollout.)
One caveat: the C300 ships with hardware for wood and metal desks. If you have a glass desk, you'll need a different solution. I'm not 100% sure, but I don't think the package includes a template for a glass top. Ask before you buy.
Scenario 3: Rack Power — Tripp Lite Vertical Rack PDU
When someone searches tripp lite vertical rack, they usually mean a vertical rack PDU—the power strip that runs along the rear vertical rail of a 19" rack. That's the product I'd pick for a standard 4-post rack. It keeps power off the floor and doesn't use up a horizontal RU. In our network closet, we mounted one on the rear left rail and left the right rail for cable management.
Don't assume a horizontal PDU is always better. A vertical PDU is often cheaper per outlet and easier to route cables. The tradeoff is access: if your rack is against a wall, you'll need enough depth to reach the rear. The most frustrating part of PDU ordering is that depth isn't always in the product title. You'd think written specs would prevent mistakes, but interpretation varies wildly.
Scenario 4: Backup and PoE — UPS, and the NXP vs. Switch Question
For UPS sizing, the conventional wisdom is "buy as much VA as you can." My experience is the opposite. We have two closets where a 1000VA line-interactive UPS covers the network stack because the actual load is around 400W. A bigger 1500VA unit would have added cost, weight, and battery replacement expense without buying us real runtime—the remaining runtime at 400W is already enough for a graceful shutdown. Take this with a grain of salt: your load may be different. Get a load meter or add up the nameplates.
If you need PoE for a camera or access point, the NXP vs. PoE switch question comes down to growth. In our case, two cameras and no plan to add more meant an NXP injector was the honest choice. If you think you'll add devices later, a PoE switch saves you from a pile of injectors. Either way, get the total cost with cabling and mounting, not just the box price.
How to Decide Which Scenario You're In
Use this quick test:
- Are you putting HDMI through a wall? → P164-000-KPBK8K, plus wall plates and cables.
- Are you mounting a tower PC under a desk? → C300.
- Are you distributing power inside a rack? → Tripp Lite vertical rack PDU.
- Are you protecting gear from outages? → UPS sized to actual load.
- Do you need to power two PoE devices and never expand? → NXP injector. Not sure? A small PoE switch is the safer bet.
The part number can be long, but the decision doesn't have to be. Write down the actual job, measure the space, and ask what's included in the quote before you sign anything.
