One hundred amps,
continuous.
Built for the big 5V installs: 100A continuous at 5–24V, from 500W at 5V to 2,400W at 24V. Same 16 fused outputs as the Power-7, fed through M5 bolt terminals, two 60A MIDI fuses and thicker copper planes.
In production since 2022-11, with a small 2024-10 revision adding extra LDO protections. Same layout, same terminals, same ratings. Changelog in the version history.
Same outputs. Double the current.
At 5V the amps pile up fast: one 300-LED strip can pull up to 13A. The Power-7HC keeps the Power-7's 16 fused screw-terminal outputs and rebuilds the input stage around M5 bolt terminals, two 60A MIDI fuses and thicker copper planes that keep voltage drop low. The red display shows what actually arrives at the board.
Built for the 5-volt math.
Megatrees and prop farms outgrow 50A quickly at 5V. The 7HC doubles the ceiling: everything new sits on the input side, everything downstream works like the Power-7.
Bolted in, properly fused
Power lands on 2× M5 bare bolt terminals taking ring, fork or lug crimps only: no bare wire, no ferrules. Each input runs through a MIDI bolt-down fuse (2× 60A included, 60A max), and both terminals come from the same supply for the full 100A.
Thick wire, non-negotiable
Feed it with at least 2× 10 AWG; 8 AWG and 6 AWG are highly recommended. The reason is blunt: thin wire can melt before a 60A fuse pops. Size the copper for the fuse, not the other way around.
2,400 watts, one board
100A continuous: 500W at 5V, 1,200W at 12V, 2,400W at 24V. Thicker copper planes than the Power-7 keep voltage drop low, and the board is rated for roughly 25 °C above ambient at full load.
Sixteen familiar outputs
Outputs are identical to the Power-7: 16× 7.62 mm screw terminals in four banks, max 10A ATO fuse and a blown-fuse LED each, cable up to 12 AWG. The SV5.5-5 double-up trick still applies: two terminals, two fuses, 20A.
Happiest on top
Same trade-off as the Power-7: terminals sit higher than the fuses, so fuses are unreachable beneath another powerboard. Run it as the top powerboard or pre-wire it. A brainboard above obstructs nothing.
Feeds the brains too
QPowerPost sends protected power up the standoffs to every brainboard above (1.5A PTC-fused), plus a spare pluggable brainboard-feed terminal if you skip the posts.
Every terminal, labeled.
Quindor's annotated power-flow map of the Power-7HC. M5 bolt inputs with MIDI fuses, sixteen screw-terminal outputs in four banks, QPowerPost in the middle.
Both terminals, one supply
Each M5 input carries up to 60A through its MIDI fuse; the full 100A needs both wired. Always feed both from the same power supply, never from two.
Front 4A, middle 8A
Even with 100A on tap the per-run rules stand: about 4A through a front feed, about 8A through a mid-strip injection. Interleave heavy and light runs, and map the feeds with the ultimate power injection guide.
One PSU per board
Never wire two power supplies into one powerboard; behind 2× 60A fuses a load-sharing fault gets serious fast. One big PSU can feed several powerboards, but each board gets exactly one source.
The numbers that matter.
| Continuous power | 100A recommended max: 500W @ 5V · 1,200W @ 12V · 2,400W @ 24V |
| Voltage | 5–24V (one voltage per board, one PSU per board) |
| Inputs | 2× M5 bare bolt terminals, ring/fork/lug crimps only (no bare wire, no ferrules); MIDI bolt-down fuse per input, max 60A each; both terminals from the same PSU for the full 100A |
| Input cable | At least 2× 10 AWG; 8 AWG and 6 AWG highly recommended (terminals accept up to 6 AWG with the right crimp) |
| Outputs | 16× 7.62 mm screw terminals in 4 banks, identical to the Power-7; fuse socket per output, max 10A ATO; cable up to 12 AWG with ferrule |
| Double-up | One SV5.5-5 fork crimp across 2 adjacent terminals parallels 2 fuses: up to 20A per combined output |
| Fuse type | LittelFuse MiDi bolt-down on inputs (2× 60A included), ATO blade sockets on outputs; blown-fuse LED per output |
| Capacitors | 2× 1,500 µF 35V bulk + 1 µF 50V per output |
| Copper | Thicker copper planes than the Power-7, keeping voltage drop low at full current |
| Monitoring | Onboard 7-segment voltage display (reads true board voltage, drop included) |
| Brainboard power | QPowerPost via standoffs + spare 5.08 mm feed terminal, both PTC-protected at 1.5A |
| Stacking | Fuses sit lower than the terminals: unreachable beneath another powerboard. Run it on top or pre-wire; a brainboard above obstructs nothing |
| Thermals | ~25 °C rise above ambient at 100A continuous |
| Mounting | 4× M3 holes (GND); 5× M2.5 QPowerPost positions; board height 30 mm; components on the back, so always use the included standoffs |
| Advised PSUs | Mean Well HRP-600-5 (125A @ 5V), LRS-600-5 (100A @ 5V) or SE-1500-12 (125A @ 12V); run PSUs at ≤80% |
| In the box | 2× 60A MiDi + 16× 10A ATO fuses, 6× M5 8 mm screws, brainboard feed connector, full standoff and screw kit |
Revisions, documented.
| Version | Released | What changed |
|---|---|---|
| v1r1 (2024 batch) | 2024-10 | Small revision: extra protections around the onboard LDO. Layout, terminals and ratings unchanged. |
