" rel="nofollow - I am building a new computer with an ASRock AB350 Gaming-ITX/ac with an AMD Ryzen 5 1600 chip. I can not get any of the system fans or the power supply fans to spin up after everything is plugged in. I have rechecked the front panel cable connections to the motherboard three times by disconnecting and confirming the orientation of the cables per the motherboard manual. I have also disconnected and reconnected the 24 pin and 8 pin CPU power cable to the motherboard and the power supply. My concern is that I don't even see the blades on the fan to the power supply spinning. Would this lead you to believe that I have a bad power supply (EVGA 750 B3, 80 Plus BRONZE). I'm trying to figure out what should be returned first, my motherboard or the power supply? All components purchased as new from Newegg. |

wussery, please see here: http://support.antec.com/support/solutions/articles/1000015319-is-my-power-supply-dead-the-paperclip-test" rel="nofollow - http://support.antec.com/support/solutions/articles/1000015319-is-my-power-supply-dead-the-paperclip-test Disconnect all power supply cables and use the paper clip. If the PS does not power up, it is dead. Several people here have had problems plugging the 4-pin or the 8-pin CPU and PCIe power cables in the wrong socket. Make sure they are all plugged correctly.

I was told to look at this video from Corsair to rule out a power supply issue. I have confirmed that my power supply is not the issue as the fan on the power supply and one connected fan did work when connected to the power supply. I will follow-up with Newegg to get a motherboard replacement. |

Just a little note of caution. Not all PSUs use the same pins for manually jumpering them with paperclip. Most manufacturers/vendors do give instructions on which pins to put your paperclip into for which models. Some units require a load (a case fan will do) whilst others are happy to work without a load, and will show they are on by spinning their own internal fan. I panicked when I had to check my old Corsair HX520, so I spent a bit of time looking around for instructions. When I got the new Seasonic Prime PSU, the instructions are were quite the same. ------------- X370 TaiChi | 1700X P3.10 stock clocks | (2x 16GB) 32GB FlareX 2400MHz. https://valid.x86.fr/ikadaa" rel="nofollow">

thermaltake do a psu tester that acts as a load as well for running thru tests circa £20/$20 working isnt actually a sign its a good one so to be honest the paperclip test just shows its can start up it dosnt test the ability of the psu to perform as required i went thru my spare psu;s when i got this tester and two 'working' ones failed the tests .......... ------------- [url=https://valid.x86.fr/jpg250]  [/url]3800X, powercolor reddevil vega64, gskill tridentz3866, taichix370, evga750watt gold |

^ That's absolutely true too. Although, if you are handy with a multi-meter you could probably check things yourself - I am not, so I would by a tester. When I got the new PSU I just did the paperclip test to make sure it wasn't completely D.O.A. I chucked it into the old system to get that up and running before I had parts for this one. It was tested in the old system. ------------- X370 TaiChi | 1700X P3.10 stock clocks | (2x 16GB) 32GB FlareX 2400MHz. https://valid.x86.fr/ikadaa" rel="nofollow">

Whenever you have an issue where a freshly built system won't even power on for the first time, check to make sure the Clear CMOS jumper is not set to the clear position. If it is (sometimes left that way by the reseller if they check boards before sale) the board will not allow the system to power up, this is to protect the BIOS ROM. It isn't the case very often these days but I have run across the issue a few times. -------------
