Yes, but it is not just the PSU wattage you need to look at, you need to make sure the various power rails supply the amperage required.
I had a similar problem a few years back, and although the PSU was technically sufficient, there were a number of 12 v rails and they weren't rated to supply the juice to the gpu plugs.

How nice it was
I'm almost sure it should work as I've seen somebody with the same problem for a GTX750TI card which is a little bit better than my inlaw's one mounted in the same computer than my inlaw's... I truly hope this will do it. Crossing fingers here...
Thank you Dave!

As I read the first sentences of your issue I thought immediately that it was the power supply.
I've experienced this same issue with 300W and needing more powerful one. Same thing fans seem to turn, lights up but nothing from computer.
I believe that really is the issue.
Good luck.

This is what it looks like... let's see what will happen after this weekend...

Don't know if anybody has said this, but it might be the graphics drivers from the old card?...try booting in safe mode by multiple pressing the F8 key while the computer boots, you should see a Dos style menu come up that will let you choose Safe Mode (choose no graphics drivers if it gives you the option).
If you can get in safe mode, un-install the old graphics drivers and reboot back to normal mode, then install your new graphics drivers and software for the new card.
Not 100% sure that's what it is but if you have tried all the hardware things, it might be it.

This is not the current reason as the computer is not passing the BIOS POST screen... Probably this is what will happen after the HW issues will be solved...

If there are components that you can unplug to temporarily lower the power draw, then try that.
Additional hard drives, DVD-ROM etc.
If that works then you will know that the PSU isn't beefy enough and you need another one.

If there were lots of things there I would test it but only disconnecting the DVD probably won't make any difference...
Anyway I'll make some testing before getting the new PSU.

Yeah, disconnecting the DVD probably won't make any difference if there's no DVD in it.
Good luck.

Ok those are my ideas:
- Can you try this card in another PC, it could be a damage Video Card.
- I smell that you can have a compatibility issue, try to check if you main board chip-sets are compatible with this Video Card. Not sure how old is the main boards, it could be just a setting in the Bios. (do it before plugging the Video Card)
- Try the 400Watts +, maybe that is all you need.

Hi!
I won't be able to test the card in any other computer, and it looks like there is a compatibility issue between the motherboard and the card itself plus not enough Watts from the PSU... so I'll have to change the PSU and then do some tricks I've seen in a youtube video where they explain how to make it work with his motherboard...
Thank you for your post!

Simple Advice: NEVER help friends or family with their computers! ))
Honestly, it sounds like putting a new Power Supply in there will work fine.
The Wattage is the maximum output, not the amount of power FORCED into the system.
It will simply let the video card draw the extra power it needs. ($30-$60.00)
Considering your time and what the adapter costs. The power supply is probably the fastest simplest way to wrap this up.
I jumped into this thread because after Microsofts Update, a few programs started misbehaving and I had to install 7 different versions of my AMD RADEON driver to find a stable one... I was thinking I was not alone... LOL

Probably. Its likely drawing so much current at some voltage that its drooping too low. If it has a connector for the power supply to directly connect to it, you'll want to connect that too -- sometimes the traces on the motherboard just can't supply the kind of current a graphics card needs.
Even if you can get the card to work with his current power supply, you probably want to upgrade it. When he pushes the thing really hard, it could draw enough to cause the system to be unstable.
FYI, a graphic card's power supply specs are not because it needs that much power itself, its usually because PSUs of that class have sufficient amperage at some needed voltage. That's too fiddly to be worth the trouble, but if you know how to check it, its worth doing -- not all PSUs of a given wattage class have the same voltage/current capacities.
We can program with only 1's, but if all you've got are zeros, you've got nothing.

Yes, after reading a lot of posts here I've become aware of how the PSU's work +/-.
Thank you for your recommendations!

THE...PROBLEM...IS...THE...PSU. REPLACE...IT. PERIOD. END...THIS...PAINFUL...THREAD.

As far as I've seen, the PSU is one of the problems.
It looks like the GPU needs at least 400W and the current PSU has only 300W. This is clear. Now, after some nice posts of other members I've known that there are other details that are important regarding the PSU capabilities which I'll double check at the shop this weekend.
But, there's always one but, this is 100% sure not the only problem.
After receiving some answers, I've seen that the motherboard installed in that computer has strange compatibility problems and that I'll be forced to update the BIOS from 7.13 to 7.16A which is the latest version from 2012 and even after doing that I'll have to make some extra steps to make it work.
Now, I'm curious: why you are shouting? why this was a painful thread?
This community is great to get help and again it has proven that it works wonderfully well to provide it...

Probably I won't need that amount of Watts, but let's see what we can find at the shop this weekend.
Thank you!

It's been a while since I have done a lot of work with graphics cards (and I don't have time to read all the posts, maybe this was already suggested.)
Have you tried putting the old graphics card in, firing up windows, and switching to the generic VGA driver (can you still do that with newer versions of Windows?) and then putting the new card in?

Nope, this will be the second set of problems (software ones) now the computer is not capable to go after the BIOS POST screen, therefore the OS drivers are still not the issue...
Thank you!

This guy has the same problem as you and he's got a 600w PSU. It seems to me to be an incompatibility between the HP bios and the nvdia card.

Without prolonging the thread too much I just wanted to mention that I have an nVidia card which requires an additional plug from the PSU; however if you do not plug in the extra plug, the system will still boot into windows just fine. You then get a friendly reminder/warning when you log in from the nVidia driver that the card cannot achieve peak performance without the extra power. But it works just fine for non-game stuff. So I'm putting my money on Paul's theory.

Yes Paul!
You are the second one to post the same video here and it looks like there's an incompatibility issue here... I'll test it and see what would happen if I would select the PXE network boot in the BIOS settings as the default option, if that mitigates a little bit the issue and my inlaw is happy I'll be happy too, if he is not happy then it will be time to get another motherboard and some thermal paste for the processor...
Thank you for posting!

No problem. I've had similar issues on an older HP mobo and nvidia card. One particular machine ground to a near halt after adding an nvidia GT8800 card. On the post screen you could watch it take a second or two to draw each individual character. Boot time was something like 30 minutes!!
