Default Question about Seasonic platinum 1200

https://imgur.com/gallery/hwJYR

I just ordered this power supply. It has 6 ports on the left side for pcie. However, despite the fact that it has 1200 Watts, it can only use 5 gpus and it only came with 4 pcie cables.

Here’s my question... can I get a 6 pin to 6 pin cable and plug it in the peripheral side and connect another graphics card? It’s a single rail psu, if that makes a difference.

Next time, ask your questions before making your purchase.

I’ll return it. Which model should I buy? I’m looking for 1200 Watts with support for 6 graphics cards.

What graphics cards are you planning on mining with?

By the way, thanks for your time sir.

They will all be running under 150 Watts each. Currently 4 cards measure at 575 Watts using a killawatt meter.

Can you be more specific? There are a lot of different versions of each graphics card with different requirements. Also which risers are you gonna use and which motherboard?

Prime 1200 chart says 5 GPU support, it isn't that you look for a 6pin Periph cable, it's that u contact Seasonic & ask for the details on how to buy a loose 5th GPU cable, or, using platform compatibility, which other models of Seasonic GPU cables could be purchased & find a loose one on eBay etc. Resources like the CableMod Compatibility Chart help explain which models can interchange cables, which when I look at their list, it amounts to 'every' model since 2014 can interchange Grfx cables ... Seasonic Rep is a forum member here, which is nice

The new Seasonic 1300w has a full front panel, comes with x6 cables, possible support of x7 GPU (chart 1 top lists 1300w, but may be a typo; full front panel means it probably deserves to be listed in Ultra Ti chart 2), available newegg

Anything coming from Seasonic Corsair EVGA @1000w + gets my vote, with the exception I felt the new Prime 1200 needed a full front panel as found on the new 1300. Good luck

So, the Seasonic PCIe cables are one-to-one and that's where you're running into an issue. You can get pig-tail cables, but I don't know what the pins Seasonic uses on the modular interface support. So it's probably best to find a PSU with either enough modular connectors on the PSU, or is made to support pig-tail PCIe cables.
