question Will my PC now get drunk with power? (from 1x4 pin to 2x4 pin CPU)

[Steven P. Administrators]

You may remember me from the rate my 2023 build thread.

Well I should receive the new build today (will post pics etc once I am up and running) but before I switch to the new build I want to make the old PC worth selling. I managed to find an unused (new) EVGA 750 BQ PSU for sale for only €45 so I ordered it and fitted it today.

One thing I was unaware of (and because near the top of the board is impossible to see properly) I saw that the 550W Be Quiet PSU only has the 1x4 pin connected to the board for my i9-9900K, this would have been fine with the i5-9600K (just about) with its 95W TDP but the i9-9900K has a PL 2 profile of 119W. Lol!

So I have fitted CPU 1 & 2 now

And with PSU fitted.

This is the PC I will be selling:

• Be quiet! Pure Base 600 ATX (black) with tinted glass and optional metal side panel
• EVGA 750 BQ, 80+ BRONZE 750W
• Gigabyte Z390 AORUS PRO WIFI (with Gigabyte TPM Module 2.0)
• Intel Core i9-9900K
• Cryorig H7 CPU cooler
• 64 GB G.Skill DDR4 Ripjaws-V 3200Mhz (4 x 16 GB)
• KFA2 RTX 2070 SUPER (8 GB DDR6)
• C:\ Samsung 980 1 TB PCIe 3.0
• D:\ Intel 660P 1 TB PCIe 3.0
• E:\ Samsung 870 Qvo 2TB SSD
• F:\ LG BH10LS38 (CD/DVD/BluRay writer)

Boxes and receipts for all of the above.

A 1x4-pin can run a 9900K as well but the extra juice (if and when the CPU needs it) is always a good thing.

Dude, we had similar build threads at the same time, and I had the exact same thought while building.

Hello,

It will be fine.  The CPU will only draw the amount of power it needs over the connector.

Why sell the PC? Use it as a lab machine, learn something that's more than scratching the surface of client operating systems.

Mine has this as well.

I tried plugging in both when I first fired up the machine... she had a Ryzen 7 3700X. Wouldn't post.

I tried plugging in both when I fired it up with the 5800X. Wouldn't post.

Seems the board may only post with both if it detects the 5900X/5950X. So... with a 65W or 105W, my board just runs on the 2x4.

+1. Stick some more RAM in it and use it for loads of VirtualBox machines.

That's what I thought it would take back in the day, for the boards hosting the twin AMD FX-74s. If memory serves, both of those 125W? Coughing up at least 250W just for the pair of chips alone.
