Question 1

Just installed in a new system. When I hit the power button on the motherboard the CORSAIR HX1200 PSU just "clicks on for a few seconds, clicks off, clicks on for a few seconds, clicks off". It is on just long enough for the CPU and GPU cans to start turning. Is this DOA?

Accepted Answer

Make sure you also have the additional 4  or 8 pin connected on mother board, for CPU. Don't use older or other manufacturer cables on this psu, some  modular cables have different pin out. Those are most common things that cause this issue. Less common on hook your ssd, some ssd have thin shell and close tolerance to internal parts, have seen them ground out. Without more information that's my best guess for right now hope it helps

Question 2

Is this ATX 3.0 and PCIE 5.0 ready?

Accepted Answer

The provided product information does not indicate that the CORSAIR HX Series HX1200 CP-9020140-NA 1200 W Power Supply is ATX 3.0 or PCIE 5.0 ready.

Question 3

How many PCIE cables come with the 1200w model?

Accepted Answer

The full cable breakdown is listed under the Specs tab. In this case, "4 x 2 x PCIe Cable (6+2)" to answer your question. This means, 4 cables with 2 connectors each, for a total of 8 connectors. Each connector is the (6+2) style which means it can be used as either 6-pin or 8-pin.

Question 4

How many PCIE cables come with the 1200w model?

Accepted Answer

I'm too lazy to remember the number of cables. But you'll have enough cables at the end, and some more than necessary, don't worry about it.

Question 5

What cables can I purchase to have additional cables? I need compatible 8pin to dual 8pin etc

Accepted Answer

These power supplies are pretty limited, suggest contacting corsair. I had to use a million adapters to get the connections I needed. By the way periodically check cable temps at power supply, have several friends have these melt down.good luck
