What should I do if my PSU has 1 CPU power port but my motherboard has 2 headers

[SetSakara2]

I purchased a Segotep 650W SFX PSU for my build and I want to use the ASUS ROG Z690-E as my motherboard. There are 2 headers on the motherboard but I only have 1 CPU power cable and 1 CPU power port on my PSU. Should I use a splitter or can the system run with only 1 motherboard power header plugged in? I can't return this PSU as I bought it open box online and is no longer returnable.

If you trust the PSU, often times it works when you only put in a 4 pin instead of 2 (or one 8 pin)

There are 2x8 headers on the board and I have only a 1x8 setup with my PSU, will it work with only 1 header plugged in?

there is a good chance it will but i cant guarantee it, bi cause i only tried it with one 4-pin instead of the 4+4-pin

What GPU though?

Edit: I could have sworn, the original post said 560W PSU. 650W should be good for most GPUs.

What cpu you want to put in it?

Most of the time it will work, but it will limit the amount of power that can be used for OC.

It should "work" but it is not the best solution

Depends on what processor you're going to be running but those Segotep PSUs are pretty meh, typically you only need to have one plugged in for normal CPU function, the second 8-pin is usually just for overclocking. However, if you have an i7 or higher I'd recommend being safe and plugging them both in anyway. 

 

A list of your full specs would be nice.

 

If I could, is there a reason you went for a more of a budget PSU and an open box at that? Clearly from your motherboard choice you had a decent budget as that's a fairly overpriced board.

A single 8-pin EPS CPU power connector is rated for up to 336W.

Unless you are doing some sort of INSANE CPU overclocking, a single 8-pin is plenty.

 

Board manufacturers have 2x 8-pin EPS connections for those 5% of people who WOULD need it. For day-to-day, there is no need.

 

A few of the Segotep PSUs are actually decent quality / performance.

It depends on WHICH "Segotep 650W" you bought.

 

What are you trying to power?

What CPU?

What graphics card?

etc, etc?
