1200W modular power for a modern black ATX 3.1 build
1200W rated outputATX 3.1 / PCIe 5.180 PLUS PlatinumNative 600W 12V-2x6
The ENERMAX Platimax II 1200DF Black is a 1200W fully modular desktop power supply, identified by EPS1200P-NPX. It combines ATX 3.1 and PCIe 5.1 support with 80 PLUS and Cybenetics Platinum certification. A native 12V-2x6 cable supports up to 600W GPU power, while the black enclosure and modular cables suit coordinated PC builds.
Best For: High-power desktop builds that need a black ATX PSU, native modern GPU connection and flexible cable routing.
Before you order: Check the complete system power requirement, case clearance and connector count. Use only the supplied compatible modular cables. Seat the 12V-2x6 connector fully and allow at least the manual-recommended 35mm before bending the cable. The 600W GPU cable rating is not additional power beyond the 1200W PSU total. Fan-stop operation depends on load and temperature.
What's in the Box
- Black ENERMAX Platimax II 1200DF PSU.
- Modular cable set: 24-pin motherboard, two CPU 4+4-pin, three PCIe 6+2-pin, one 12V-2x6, two four-connector SATA harnesses and one four-connector Molex harness.
- Four mounting screws and AC cord; regional plug varies.
- Datasheet states a cable comb kit is included.
- PC case, motherboard, processor, graphics card and drives are separate.
What It Means in Practice
- Connect only the cables needed for the installed components.
- Use the native 12V-2x6 cable for a compatible GPU and verify full seating and bend clearance.
- Account for 150mm PSU depth plus modular plugs and cable routing room.
- Use the D.F. switch for the manufacturer dust-clearing rotation cycle and keep normal ventilation clear.
What Will Not Work
- Not an external AC adapter, UPS or redundant server power module.
- Do not interchange modular PSU cables merely because a connector appears to fit.
- Up to 235% power excursion is a 0.1ms transient condition, not continuous 2820W output.
- The fan can run below 60% load when temperature requires cooling.
- Manufacturer warranty terms and regional handling apply; no change to shop warranty fields is implied.

Frequently Asked Questions
Is this the black version?
Yes. EPS1200P-NPX is the black model, with EAN 4713157728579.
Does the 600W GPU cable add to the PSU rating?
No. The PSU has 1200W rated total output; 600W is the supported capacity of its native GPU cable.
Is the fan always off below 60% load?
No. The manufacturer also uses a temperature condition, so cooling demand can start the fan.
Can I reuse modular cables from another PSU?
Use only the supplied compatible cables. Matching connector shapes do not establish matching PSU-side pin assignments.
Singular Expert Insight
Plan the power path and physical routing together. Total system demand, the GPU connection and the space between the PSU, case and side panel all matter. Keep the native GPU connector fully seated and avoid forcing a bend immediately at the plug.
Buyer’s Guide
✓ Buy it if You need a black 1200W ATX 3.1 modular PSU with native 12V-2x6.
✕ Skip it if You need a compact SFX unit, external power adapter or redundant hot-swap server module.
→ Also consider Case depth and cable clearance, actual system load, GPU connection requirements and regional warranty service.
