XFX 550 TS Power supply not working?

[Xennox70]

Just bought a new psu to replace my faulty old one and after turning everything on it doesnt boot up no fans nothings, however the graphics card's LED turns on any ideas?

I connected a 24 pin to the motherboard, pci e to the graphics card, 4pin to the cpu and 2 power cables to the hard drives.

best to test the psu then if you've got everything connected properly. Did you get a jump starter with it?

you can test your psu with a paperclip and see if the fan spins like in this video: https://www.youtube.com/watch?v=5FWXgQSokF4. if it doesnt then then your psu is bad.

Its a bit weird for both of them to stop working? could the power button be loose or something?

ita unlikely but you could check the front panel headers for that. I'd still recommend testing the new one. You should always test a new item before using it. What went wrong with your old PSU?

it was restarting my pc at times I posted about it and went to buy a new psu and now both dont work :\

id recommend testing the new one. And if that does work then I'd move onto testing individual components to see which one is the problem

just tested the psu with the paperclip and the fan started spinning what could be the issue then?

Its time to move onto individual components. okay so if the PSU fan spins fine, take the mobo outside of the case and place it on something safe. Next connect the 24 pin plug to your motherboard as well as the system fan. Don't install your cpu or cpu fan. Turn on the power supply and note if the psu fan as well as the systems fan spins. If it doesn't then it's likely your motherboard is busted. But if the systems fan does spin, install the cpu and cpu fan. Power it up again and see if all the fans spin, if they dont spin then you know your CPU/ cpu fan is the issue. However, if all the fans spin, next place your RAM, power it up and if the fans don't spin then the RAM is the issue. Continue to do this for the rest of the components. I am afraid that your old PSU damaged some components but im hoping thats not the case. Out of interest, what make and model was the old PSU?

unfortunately that PSU is one of the lowest quality PSUs out there. It has the potential to kill your system and they are unsafe. Follow the steps I outlined in the previous post to see if its a component but i fear that your old PSU has killed your components
