I want to upgrade the power supply in my computer.

[Moog]

I'm using a crappy Dell Inspiron 660(even though it was around 700$). At the time I got it and with the crappy graphics card I put in it, I could run a lot of games, but now that I want to play games like bioshock infinite and skyrim on medium-high graphics, I need something better.

 

After doing some research, my power supply in this computer is most likely 300 watts, and I need at least 400(my friend is telling me just to get 600). I plan on getting a AMD Radeon HD 7750 at least.

 

 

How do I accomplish installing a new power supply without blowing up my computer or house?

 

 

(sorry if im being dumb)

Depends on the card that you use and the other hardware in use. A Radeon HD 7750 or GeForce GTX 650 draw very little power really. The HD7750 draws 75W max and the GTX 650 draws 64W max. What are your full specs? Depending on your current video solution (if you're running another discrete card), you may not need a new PSU. Wouldn't be a bad idea really, but it's not always necessary. Also, are you really sure you want to blow up your computer or even your house? That sounds more like something you'd want to avoid. Just sayin'.

What other info do you need on my system?

 

I am running:

Windows 7 SP1

Intel core i5-2320 3.00 GHz

8GB RAM

GFX: Nvidia GeForce 210

With a Radeon HD 7750, you should be fine without a new PSU. Your system is already pretty low power. Since you'll have to remove the GeForce GT 210, you'll free up another dozen or two watts

 

That said, the sweet spot for GPU performance is closer to a GeForce GTX 660.

It's about $200 for a card, but they're more than twice as fast as a Radeon HD 7750. They'd also be simpler for you to install: installing an AMD graphics card requires a couple extra steps to strip the system of nVidia's software and drivers--so to prevent future issues.

In that case, then, you'd need a new power supply.

I'm still thinking a power supply upgrade would be a good idea, just to be safe.

 

Last time I installed a graphics card with a power supply that was below the requirements I killed my computer(you might remember that post).

 

 

Thank you for the help, I'll post any more questions I have on the subject in this thread.
