Black 10 cm Molex breakout cable splitting into 12V 7V 5V lines

Phobya

Phobya 4-Pin Voltage Reduction Cable 5V 7V 12V 10cm Black 87490

SKU CH-JWEY-487BK

Molex breakout cable splits one 4-pin connector into 12V, 7V and 5V lines, 10 cm long in black

  • Cable length3.94 in (10 cm)
  • Product colorBlack
  • One cable delivers three voltages from a single Molex connector
  • 10 cm length keeps cable routing tidy inside the case
  • Black finish blends with dark-themed builds
  • 4-pin Molex input works with standard PSU leads
  • Provides 12 V, 7 V and 5 V outputs for varied fan or accessory needs

Product Identity

The Phobya 4-Pin Voltage Reduction Cable is a 10cm internal power adapter that splits one Molex connector into three separate voltage lines. It delivers 12V, 7V and 5V outputs for components that require lower voltages than a standard supply provides.

Suitability

This cable suits builders who need to run low-voltage fans, LED strips or legacy devices from a single Molex header without adding a separate power supply. It is not for systems that lack a free Molex connector or for installations where a 3.94 in. reach is too short to bridge the distance.

Deciding Specification

The fixed 10cm length and three-voltage breakout are the critical details; if your routing path exceeds 3.94 in. or you require only a single voltage rail, this adapter will not fit the build.

Questions about this item

Will the 10 cm cable length limit where I can route the 5 V, 7 V and 12 V leads inside my case?

The 10 cm length is short, so the three voltage leads will only reach components close to the Molex source; plan routing before installation.

What is the first limit I hit when running all three voltage lines continuously?

The single 4-pin Molex input caps total current to what that connector and the PSU rail can deliver, so combined draw across 12 V, 7 V and 5 V cannot exceed that rating.

Does the cable add noticeable heat or noise when powering fans all day?

The passive cable itself generates no noise and minimal heat; any warmth comes from the powered devices and the PSU, not from the 10 cm wiring.
