New PS, Dell vostro will not boot

BGroves · Sep 4, 2014

I have two Dell Vostro 220 that are dead. I installed a new Diablotek 500watt ps in one. I installed a diablotek 600watt ps in the other. Neither unit will boot. The fan in the PS does not spin, The CPU fan does not spin. the case fan does not spin. The led on the case power button is yellow so there is some power. The green light on the ps is lit also. Not sure what I am missing. There was a ATX12 4pin connector on MB. The ps have 6pin ATX12. I just positioned that plug so it is inserted with two ping hanging off side. Any ideas what may be going on for no boot?
Thanks,
Brian

Diablotek 500watt is one of the worst on the planet , using one puts your PC at risk.

Replace right away.

Solid amber light on the power button is indicative of either a power supply or motherboard problem. This is a known issue with that line. Cut your losses and scrap 'em.

ATX12 plugs are ether 4 or 4+4 pins not 6 pins, you are using a pci-e 6 pin plug for a GPU. Magically the dell computer knows this and wont boot up. look harder at the bundle of wires coming out of the PSU and find the ATX12 4 pin cable.

Thanks folks. I may have two problems. A. Both Dell Power Supplies pulled from the dead units check out good with the cheap powers supply tester I had. I brought them home to test them. B. I did find the 4+4 ATX12 plug in the new ps, so I was incorrectly using the using pci-e 6 pin plug. I'll correct the plug issue and see if that changes anything . If not should I assume it is a MB issue and do as suggested and scrap them. Thanks, Brian

When I plugged the correct ATX12 4pin in MB rather than the pci-e 6pin the pc lit up. Both units were the same cure. The two Dell power supplies may have tested ok but they were not. My power supply tester is not reliable. Thanks for the help.
