Ruth's sister 800W internal power cable

SKU CH-KE5V-78N3M

Delivers 800 W via a non-modular ATX design with Active PFC, 20+4-pin main connector, 8-pin CPU power, two 6-pin graphics connectors and three SATA ports

  • Delivers 800 W for demanding builds
  • Active PFC corrects power factor across 90-264 V input
  • Non-modular design keeps all cables permanently attached
  • Three SATA connectors power drives and peripherals
  • 20+4 pin and 8 pin CPU connectors fit standard ATX boards

800W non-modular ATX supply

This 800W ATX unit delivers 12V power through a fixed cable set that includes a 20+4 pin motherboard connector, an 8-pin CPU plug, two 6-pin graphics connectors, three SATA ports and three D-type connectors. Active PFC operates across a 90-264V input range making it suitable for desktop and server builds. The non-modular design means every cable is permanently attached.

Suits single-GPU desktops and basic servers

Builders running one graphics card and a handful of drives will find the provided connectors adequate. Systems that require modular cabling for cleaner routing or need more than two 6-pin PCIe plugs should look at a different unit. The fixed cable bundle also limits flexibility in compact cases where only specific leads are wanted.

800W rated output

The 800W rating is the headline figure that determines whether this supply can handle the combined load of your CPU, graphics card and peripherals. Check the total system draw against this number before purchasing.

Questions about this item

How do I connect the 20 + 4Pin main power cable to the motherboard and which step is often missed?

Align the 20 + 4Pin connector with the motherboard socket and press firmly until the latch clicks; the step often missed is seating the separate 8 pin CPU power connector near the socket.

Which cables or connectors on this non‑modular 800W unit are most likely to need replacement after extended use?

The fixed SATA power leads and the two 6 pin PCIe cables can develop loose crimps or brittle insulation over time; they are the only removable‑type wires on a non‑modular design.

At what load does the Active PFC circuit on this 800W supply hit its thermal limit first during sustained operation?

Continuous draw near the 800W rating causes the Active PFC stage to reach its thermal ceiling before the main output rails, especially at the upper end of the 90‑264V input range.
