i upgraded my power supply to a corsair rm1000e now my computer will not post, only thing i can go by is the error lights on the motherboard which are on for the cpu and the dram.
i have checked everything is seated properly and that the cables in side are pushed in correctly. i am at complete loss as to why it is not working any help please.

I replaced all of the old cables with new ones. i am going to put the old psu back in i got a feeling my new one is not compatible with my PC, thanks for all your help guys much appreciated.

i have reset the cmos (took the battery out) was going to use the jumper but i could not because there appears to be no little plastic bit, i have reseated the ram and tried one stick at a time still the same. have not reseated the cpu yet, all with my old psu inside.

thanks for the information on clearing the cmos but unfortunately the pc will still not post, not sure what to try next? don't really want to reseat/replace the processor.

i have reseated the cpu and installed a spare air cooler that i had also removed all my rgb lighting from the case to narrow the problem down a bit, still the same lights on the motherboard also noticed the hdd light stays on at startup maybe i should reseat my nvme drive? any suggestions welcome.

i was just reading a post that was in the power supply's part of these forums and it talked about using the right cables (new ones) then i realized that i completely forgot to say that when i installed the new power supply i used a corsair custom cable starter kit (type 4 cables) along with some of the new cables that came with the new power supply, witch has led me to think that maybe i have accidentally fried something assuming the cable kit was not compatible.

yes i did check the corsair compatibility chart before i purchased the cables they are type 4 that match the psu the only problem was the RMe 1000 was not on the chart just the RMe 750, 850, and 1200 :confused:
