Hello all!

I'm building a new system for the summer. Here are the specs:

Motherboard: ASRock B450 Gaming-ITX/ac
CPU: AMD Ryzen 5 1600 AF (12nm)
GPU: GIGABYTE RTX 2060 Super Gaming OC 3x
Memory: 2 x 8G DDR4-3600
PSU: Corsair SF450 80+ Gold
Storage: 1TB Samsung SSD

I checked some websites to determine how powerful my PSU should be. All of my sources mentioned something around 430-460 W.

I bought a Corsair SF450 thinking that was all the power i needed to use my new system. After installation, nothing would show up on my screen, none of the fans wouldn't start spinning, and all i would hear from the PSU is some clicking sounds after I pressed the start button. I checked to see if the PSU works using the "paperclip method" (http://support.antec.com/support/solutions/articles/1000015319-is-my-power-supply-dead-the-paperclip-test), and sure enough it does. Now I'm thinking the power supply is either to weak or i have a faulty motherboard.

Luckily, I could borrow a working 850W EVGA PSU from my brother's system to see if my system would boot, and sure enough IT DOES! Motherboard works.

Now I order a Corsair SF600 with the hopes that everything will work fine with the higher wattage. I installed it, but now I'm having the exact same issues as that I did with the 450W unit. Checked to see if the new 600W PSU works (paperclip). It does...

Now I'm stuck and don't know what else to do. I did not change any of the cabling since the successful boot with the 850W EVGA PSU, and I'm positive my systems shouldn't require more than 500W at a given time.

Is there anything I can do? Any help would be much appreciated.

What speed are you trying to run your RAM? Any speed above 2667 MHz on your motherboard with a Summit Ridge CPU is considered an overclock.

- AMD Ryzen series CPUs (Summit Ridge) support DDR4 3466+(OC) / 3200(OC) / 2933(OC) / 2667 / 2400 / 2133

I heard somewhere that I would be able to run an XMP profile and achieve the advertised speeds of my ram. I assumed that the memory would automatically run at a lower clock until I activate this profile.

Also, the CPU im running is one of those refresh 1600 AF variants, the ones on a 12nm process.

The processor in your pcpartpicker list is specifically identified as 14nm.

Boots how? Mean has power or goes to windows.

Have latest bios since the 1600AF requires that?
Hi!

I have an update on the situation. I may have withheld dome information about how I set up my new system.

The stock cables that came with the Corsair PSUs we’re too short and so I used the spare cables of the EVGA PSU mentioned.

I did not think this would cause any issues. But after a 10 second google search and a video by Gamers Nexus (
View: https://m.youtube.com/watch?v=SDsC_PNo84I
), it makes complete sense that the system would boot with the EVGA psu and not with the corsair ones.

I‘m installing windows while writing this up, and I wanted to say that I appreciate you willing to go out of your way to help a newbie with his pc problems.
