How many PCiE 8 Pin connectors does an HX 1200 Platinum have?

Like the title says, I'm trying to figure out how many PCiE 8 pin connectors are on this specific power supply: HX Series™ HX1200 — 1200 Watt 80 PLUS® PLATINUM Certified Fully Modular PSU (corsair.com)

The product page says 8 total PCiE connectors and it appears there are 2x 6 pin connectors and 6x 8 pin connectors, but the actual PSU is labeled as if there are only 3x 8 pin PCiE and the other 3x 8 pins are CPU. It's my understanding that PCiE and CPU 8 pins aren't interchangeable, hence my confusion. Are those 6x 8 pins actually interchangeable and the cable does a conversion for the correct output?

Uh extra context I guess, I'm asking because I need a 12VHPWR cable and I'm trying to figure out if I can get a 4 way connector, or if I have to settle for a 3 way.

Referencing the screenshot you provided...

The 6-pin connectors on the PSU are used for the SATA and Molex cables. The 8-pin connectors on the PSU are used for both the EPS12V cables and the PCIe cables, as they are both 12V power cables and it is the pinout at the device end that conforms to the specific connector standard.

If possible use a 12VHPWR cable that connects direct to the PSU. that will only take two sockets on the PSU and look less messy in the case. those squid adapters were really a (unelegant) workaround, while manufacturers got their 12VHPWR cables on the market 🙂

Corsair makes a few already

Thank you for the confirmation!

Less cable clutter

This was already the plan. Unfortunately Cablemod in their infinite wisdom chooses January/February for factory upgrades every year, so I'll have to get a Corsair 2x 8 -> 12VHPWR until I can get a 4x 8 cable that I'm more comfortable with.

But why a 4x8? ^^

the 2x8 does the same job. ATX 3.0 power supplies even have a single cable for it.

the only reason behind the 4 cables is the 150w limit on the old 6+2 pin PCIE connector. it's not a cable limit. if you take a cable with no 6+2 PCIE, you have no need for 4 cables. The wire gauge is more than fat enough to take 600W
