Need help finding new PSU

by MrSlayer531 / April 8, 2014 1:33 PM PDT

I recently installed a Radeon HD 5450 on my desktop and found out that it needs at least 400W. I have a 250W PSU and I'm having trouble finding the right PSU. I want a PSU for at least 30 bucks and not something crazy like 90 bucks. I have a Compaq Presario SR5250NX. If anyone can help that would be appreciated. I'm really noobish at finding the stuff.

The 5450 should be fine.

The 400 is to indemnify the company. It should be fine.

Doesn't work still

The 5450 won't display, it runs but it won't display cause I need a better PSU. Like you said the 5450 is fine but it won't display at all.

Does the card work in other PCs? Why I ask is the 5450 is such a low power draw that when it doesn't work I'm looking for other issues.

Keep in mind I didn't start shopping for any PSU for a few reasons. You could be anywhere in the world. In the USA try Newegg.

on this one. I had the 5450 in an old Dell 530s for a couple of years with a 250 watt PSU and it ran fine.
When the Dell eventually died I installed the 5450 in a friends computer with the same 250 watt PSU and it it still running great.

OK so you guys were right about the PSU, the card is not working still, won't display and my computer won't detect it. Any ideas?

So I need to install drivers first?

When I insert the disc, it trys to detect the 5450, but it doesn't so it leads me to nothing. Should I look for it online?

Maybe a bum GPU

or cable. Have you tried a different cable or tried the GPU in another computer?

turn off any onboard video
by James Denison / April 18, 2014 2:17 AM PDT

and I'm assuming you have your monitor plugged into the back of the video card and not to the onboard video, if it exists?

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
