The StarTech.com PYO2LP4SATA is a 12-inch LP4 to dual SATA power Y-splitter that turns one legacy 4-pin Molex line into two SATA power feeds. If you are reviving an older build or running a modern drive off a vintage-era supply, this is the adapter that bridges the gap: one male 4-pin internal power connector on the input side, two female SATA power connectors on the output side. StarTech.com lists it as compatible with its own ATXPOW330HS, ATXPOWER300B, and ATXPOW400DF supplies, which makes it a straightforward pairing for retro PC power projects where the PSU predates SATA entirely.

Frequently Asked Questions

What does this cable actually connect?

One male 4-pin internal (LP4/Molex) power connector on the input side to two female SATA power connectors on the output side, so a single Molex header feeds two SATA drives.

How long is the StarTech PYO2LP4SATA?

12 inches. That is enough to reach a drive in an adjacent bay, but plan a longer extension if the target drive sits across the case.

Will it work with my power supply?

It works with any PSU that has a standard 4-pin internal power connector. StarTech.com specifically lists P/N ATXPOW330HS, ATXPOWER300B, and ATXPOW400DF as compatible units.

Is there a warranty?

StarTech.com covers this cable with a limited lifetime warranty. Check the product listing for current warranty terms and claim details in your region.

Is it good enough for a build I care about?

It is FCC and RoHS compliant. For drive load limits, check your power supply's rating for the 4-pin rail you are splitting.
