Need a new PSU
#1
Okay so I bought a Radeon HD 6750 card to upgrade and installed it in the pci express slot, turned the pc on and then nothing... The card doesn't even turn on at all but my old radeon x 1650 pro works just fine in the same slot.
So I figured I don't have enough power to run this new card so I need a new power supply. My question is does it matter what size it is (physical dimensions) because I've seen several different height*width*depth specs (although they only differ by a few tenths of an inch) Still the last thing I want is to get one and then it doesn't fit in my computer. Also it says on the card that it requires at least a 450W power supply with one 75W 6-pin pci express connector.

Also i hope this psus come with an instruction manual that tells you where to plug in all the cables because right now there are probably 10 different things plugged into it from the mobo , the fans, etc. I don't think I'll remember where everything was plugged in...

Given all of that what are your recommendations? Thank you for your feedback.

Check my PSU recommendations on this post.

The things you'll need to plug in are:
  • The mobo's power (20+4 pin)
  • The CPU's power (a 4- or 8-pin)
  • The power for HDD, SDD or optical drives (either SATA or 4-pin molex)
  • The power for the GPU if necessary (6- or 8-pin PCI-E)
  • The power for any fans or LED lights
Can't think of what else your PSU might be powering. That should cover everything. Smile

hmm maybe you just need to put a 6/8-pin into your GPU ...

buy a 4-pin to 6-pin cable and you should be good to go Smile

but if you are in the first place don't have enough W buying a new PSU is better Smile

He means something like this. Some GPUs come with them.

So, you're deciding to stick with your current PSU? You might wanna ask yourself a few questions before doing so.

How old is it?
What wattage is it?
Does it have sufficient amperage on the 12v rail?

Also, consider that it's overall quality can and will reduce it's effectiveness, as well as it's age.

i think i'll just get a new psu just to be safe. also no one answered about the size of it does it matter or are they all basically the same (so it will fit into my computer)? I know that's a silly question but I'm really new to this whole upgrading computer parts thing...

All those I recommended will fit the standard ATX12V type.

I guess the question is: What do you have?

300W !

you definitely need a new PSU
it was working fine on your old GPU and CPU

but now you need to upgrade to 500W or more

use the post Rezard have gave you
to decide which one to get

your PC was like 7 years old you basically need to change everything !

well it was manufactured in late 2008 ( AMD 780G motherboard and 8GB DDR2 RAM, Phenom 9650 Agena Quad Core at 2.30 GHz with an integrated Radeon HD 3200 256MB RAM) As you can see I upgraded the cpu to the Phenom II and got Radeon HD 6750 1GB DDR5 RAM so that should be a huge improvement.
