What this cable does and who needs it

This OwlTree two-pack adapts a single EPS 12 V 8-pin female connector into both an ATX 12 V 8-pin (4+4 detachable) male and an ATX 12 V 4-pin male. It suits builders whose motherboard requires 8+4 pin CPU power while the power supply only provides one 8-pin EPS lead. The 10.6 in length keeps routing tidy inside compact cases.

Behaviour under sustained load

UL1007 18 AWG conductors use 34 strands of 0.178 mm tinned copper each, reducing resistance during continuous CPU draw. Braided sleeving protects the insulation from abrasion and helps dissipate heat along the full 27 cm run. The Y-splitter design maintains stable delivery to both motherboard headers simultaneously.

Limits of the EPS/ATX interface

This adapter only works with motherboard CPU sockets; plugging it into a PCIe graphics-card connector will cause damage. It cannot convert voltage or add current capacity beyond what the single EPS source supplies. Builders needing independent 8-pin and 4-pin feeds from separate PSU rails must use dedicated cables instead.

Questions about this item

Does the 18 AWG wire run warm when the CPU draws full power all day?

The 18 AWG conductors with 34 strands of 0.178 mm tinned copper are rated for the current a CPU 8-pin socket can deliver, so they stay cool under continuous load.

My power supply only has an 8-pin EPS connector — will this cable plug straight in?

Yes, the female EPS 8-pin end mates with any standard PSU EPS cable, while the male 8-pin (4+4) and 4-pin ends fit motherboards with 8-pin, 4-pin or combined 8+4-pin CPU power sockets.

Can I keep my older motherboard that only has a 4-pin CPU power header?

The splitter includes a dedicated 4-pin ATX 12V male connector alongside the 8-pin (4+4) male, so it works with legacy 4-pin headers as well as modern 8-pin or 8+4-pin layouts.
