What did I do wrong?

Hello!

About a year ago, I decided to venture into upgrading my computer. I bought a new PSU (Corsair 450W) and graphics card (nVidia GT 610), both were not top of the range because I didn't want to spend so much so early. I installed both parts and they were all looking correct, so I turned the computer on, and the monitor didn't work and the PC would not work with the graphics card in.

I want to modify my newer computer now with a new 750W PSU (http://www.amazon.co.uk/XFX-PRO750W-Bronze-Energy-Certified/dp/B0045L4BJ6/ref=sr_1_6?ie=UTF8&qid=1432806723&sr=8-6&keywords=xfx+psu) and a new graphics card (http://www.amazon.co.uk/Nvidia-GeForce-Graphics-GDDR5-PCI-Express/dp/B00ICUGOP0/ref=sr_1_1?ie=UTF8&qid=1432806853&sr=8-1&keywords=nVidia+GTX+750+Ti) yet I am scared that I will have the same result again.

My system is this: http://h20564.www2.hp.com/hpsc/doc/public/display?docId=emr_na-c03536888 in case you want to have a check.

Many thanks,

Jack

Sometimes when you install a new graphic's card, it'll only work with the drivers installed. It also says on your PC's site that the integrated graphics will stop working if you put in a graphics card so you could of plugged the monitor in the same slot as usual.

You don't need to replace your PSU. It'll handle just fine.

Ahh, that makes sense now, I was very amateur to the whole thing, but I think I know what to do now. Also, I was told that I would have to buy a new PSU because my system currently uses 250W of my PSU and the grpahics card needs 150W aswell which is why I thought I would need a new PSU. Could you explain why please? I'm not disagreeing with you, I just want to understand.

Thanks,
Jack

Well 750 watt is totally overkill. A 550 watt should be fine mate.
