1U Industrial PDU -- built for a rack that's actually working. Same wiring shape as the standard/heavy-duty tiers (one grid "in" port, switched outlets) at four times the heavy-duty tier's power budget.
12 outlets, 1000W total capacity -- comfortably covers a NAS or Game Server near its real ceiling (both can climb to 500W under heavy load) alongside a router, switch, and other everyday gear, without needing to daisy-chain two or three smaller PDUs just to keep the lights on.
Still a shared chain: every outlet's load stacks against the same 1000W ceiling and the same grid slot. A bigger tier moves the wall further out, it doesn't remove it.
The same sustained-overload fire hazard applies here too, and at this power level a runaway chain is a genuinely bad day -- with up to 12 outlets in use, a fire here risks spreading to everything plugged directly into it.
Its 12 outlets aren't limited to feeding devices in its own rack -- cross-rack cabling lets this chain power devices racked in a second, physically separate rack over a real cable link, treated identically to local power everywhere it matters.
Tip: if you're chaining two Heavy-Duty PDUs just to keep a NAS or Game Server online, this is the upgrade that actually solves it -- one unit instead of a chain.
