Athena Power CABLE-P4EPS8 7.75 in. P4-4pin to EPS-8pin Adapter Cable

Pros: Does what I needed it to.

Cons: would like to have seen the wires wrapped, but I knew that before I bought it.

Overall Review: kinda worthless writing a review on an extension cord lol.

Pros: Solves a nasty problem -- currently, it's hard to get a power supply that isn't huge, yet has dual 8-pin EPS-12V. My specific issue was a TYAN S7010 motherboard. I had an Antec Titan case with a built-in TruePower Trio 650W power supply (which only has a single 8 pin EPS-12V). The alternative was to get a power supply that was way too big for my needs (plus it was another $109). This splitter was a cheaper & easier solution.

Cons: The length of the arms of the "Y" was too short for my motherboard. I ended up getting some 18 gauge molex wire & electrical tape, and spliced in a few more inches. I would have given this product 5-eggs if I didn't need to do that (or if Athena made another version of the same product with longer arms).

Overall Review: Here's how I figured out that my splice job was a safe thing to do:

18 guage molex is rated at 5Amps.
I've got dual Xeon E5520 cpus with a thermal design power of 80w.

Given: 80W * 2/12V= 13.33A, and TPW is usually 20%-30% peak,
we're talking at most 17.33A peak (13.33A * 1.3 = 17.33A).

Each limb of the Y is made out of 4 strands of 18 guage molex wire,
so that's 4.33 A / wire, which is still below the conservative 5A/wire rating.
Each rail of the PSU is 19A, so that worked out too.

The extra voltage drop was tiny -- not a problem.
