I want to uprade graphic card for HP Compaq Presario SR1650NX.

I was told that pcie 2.0 x16 will work since it is backward compat. with pcie x16.

Will this card work http://www.microcent...uct_id=0328301?

If not, than what other card from microcenter or bestbuy stores could I get that would be good?

NO online sites since tigerdirect is having a problem processing my card for some reason.

Your motherboard has a PCIe slot (it looks like x16) and 3 PCI slots. That GPU has a TDP of 61W. Your power supply is 300W, so that should work fine.

Hi. That MOBO has an AMD 939 Socket so is an older machine ( probably came with XP installed ). The PCIe X16 slot is 1.0 ( if in fact it is an X16 slot as it looks like it rather than the x1 as it is labeled ). The Card, although x16 2.0 is backwards compatible. As long as you have a 300w PSU, you should be fine. I don't know if that card takes an extra power lead or just works off of the Buss.

[LiveBrianD]

I couldn't find any clear labeling on exactly what kind of PCIe slot it is, x16, x4, x1, and what rev, but it looks like a PCIe x16 one from the pictures, and besides, the different revs. of it are all compatible.

So I have to worry about the power supply as well? I though that I just had to worry about the connection.

I noticed that the require power suppy is 400 according to Microcenters page spec. Will the 300 work with the card?

I know you mentioned it should so I just want to check before I go get.

Edit:
Yes it has Windows XP. I might upgrade to Windows 7 if the graphic card work on Windows Xp.

Hi, Probably not or not all that well. Best to upgrade the PSU for that card.

[HG]

What card should I get from microcenter or best buy that will work with 300 power supply that is similar to that card?

I do not want to upgrade the PSU at this time.

[LiveBrianD]

I think that power supply will work just fine. http://extreme.outer...n.com/PSUEngine told me, even when I used 100% TDP, that your CPU, that GPU, a dvd burner, 2 sticks of DDR, and a hard drive, that 240W was recommended and 190W was the minimum. In reality, it will be lower than that. (For mine, I drew 300W from the wall, probably 250W from the components, and yet that psu calc recommends 300W minimum, 350W recommended.) Basically, I'm pretty sure that you're fine with that psu.

The PSU is old so it does not have the same watts as a new one It might work with that card or it might not. You can try it and see.

[HG]

What is the worse thing that can happen if I use that card and the 300 PSU? And how can I minimize it?

What other card can i get to use with the 300 PSU?

[coastie65]

In all likelyhood the performance of the card will be seriously diminished, if it works at all.

Doubtful. The 5670 could be run on his pc with a 200 watt powersupply. As long as his unit will supply at least 200 watts, he is good.

[Dellinsp531]

The worse things could be:

• Card works without any problems
  
• Card does not work and no harm to componets
  
• Card works but your componets get damage

Most power supplies do not give full 300 watts so like waldojim said. If you get 200 watts it might work, but 300 let say is running at 80%. 300 *80% is 240 watts. Since the computer is a few years old, than take off another 20%. 240 * 20% is 192 watts.

If you use the 5670 card and it works, do not run any major stress test on the computer.

I would go with Gefore 9500 or 9800 card. Those should work with your PSU without problems.

The power supply is rated based on what it can deliver, not what it draws from the wall. a 300 watt PSU @ 80% efficient draws about 375W from the wall. The 9800GT will draw considerably more power than the 5670, both at idle, and at load.

Man, don't you hate it when people spread misinformation... Even though his 300W PSU, being cheap and a few years old, probably can't provide 300W anymore, it's still enough. That power supply calculator said you need 240W. AND those often say more than you need. As I said, for my PC it says 350W recommended, 300W minimum, and I measured 300W FROM THE WALL when torturing the CPU and GPU simultaneously. Given that my PSU is 85% efficient at 50% load (520W unit), that's about 250W from the components. And nvidia claims you need 400W for that card, which is way more than you need obviously...

The rating is less than what it draws. The PSU never operates at 100% of this rating. The rating has a safety factor in it. It would overload the PSU if it pulled that many watts. Just like you can not put a 100W bulb into 60W light fixture since it will burn the light ficture. How can a PSU take 375W and work with a rating of 300W? It would not.

"300W power supply" means a power supply that has a 300W OUTPUT. Of course, the INPUT will be higher due to inefficiency in the unit. Also, even though the power supply can't necessarily provide it's full 300W anymore due to age, it can still provide enough for the graphics card in question. What don't you get about this?

Please, pretty please, take a basic electronics course. Or better yet, find a book on power supply design.
Power supplies are rated on output power. There is ALWAYS loss in the process converting from 110 (or 220) to 12V. As such, the INPUT stages are over-engineered to make up for this loss. For example, MY 750 watt PC Power and Cooling has input stages designed for up to 1100 watts to be pulled from the wall. When fully loaded, that PC Power and Cooling is actually KNOWN to pull up to 950 watts from the wall.

My PSU is 375W. Did the label it wrong with 300W?

Hmmm, That's interesting. I don't think I remember seeing a 375w PSu. I have seen 300w, 350w, & 400w. If it is in fact 375w, it should handle the card though.
