Help psu replacement gone wrong

[R1vAL5]

I bought a Lenovo m900 from Kijiji a year ago and I finally got around to upgrading the psu. While changing it out my self I unplug the 2 cables and plugged in the new psu (for the main one I did have to use an adapter for regular power to a 5 pin) but when I plug it in it made the beep it normally makes when it turns on but when I click the power button it doesn’t light up and my keyboard nor monitor show anything and my cpu fan isn’t spinning. I’ve tried so many different things and it’s not working, any advice on what to do?

Can you be a bit more specific? Do you mean the 4/8-pin CPU power (ATX12V) and the 24-pin ATX cable? Maybe take a picture of the setup.

 

5-pin sounds weird, is this a pre-built with a proprietary motherboard/PSU? What type of PSU did you have before and what is the motherboard?

The prebuilt does have a proprietary psu and motherboard but when I bought it I was given a 24 to 10 pin adapter (when I said five pin I actually meant 10 pin sry) so I just used that and the other thing i plugged in was the 4 pin cpu power. @Eigenvektor

So something like this: https://www.amazon.com/dp/B01NBRR9E1?ref=ppx_pop_mob_ap_share? — My first suspicion would be that the PSU detects that not all of its cables are properly connected and therefore refuses to power on.

 

Why are you upgrading the PSU in the first place? Did you add additional components that require more power or something? If you added a discrete GPU, most likely it also needs power. If that's the case, you also need to connect the required 6-/8-pin cables into the graphics card.

Yes that’s what the cable looks like, the thing is that the fan in the psu works but nothing else does, I upgraded because the other one was starting to fail and I wanted to put in a stronger gpu but I haven’t installed it yet ( that’s a different problem of its own).

Ok so after looking I think the adapter I’m using isn’t correct since Lenovo has a proprietary 10 pin connection so not just any adapter will work and my computer was beeping from the dvd drive just getting power I think…

does that sound right?
