    It may work with the 280w PSU but in the system requirements I posted It states 400w min. ,500w suggested. You can upgrade the PSU quite easy. Your machine specs suggest that has a few miles on it, The CPU, Memory will be a weak link in the chain. I added a Graphics card to a older machine with a 250w PSU, it started to give me trouble, and finally the PSU quit , I replaced it with a 400w PSU. That PSU worked until I retired the machine.

    That the good thing about a desktop, easy access, you can upgrade, With Limitations dictated by your Motherboad, the CPU. Memory, other components with relative ease. Do some research, what your Motherboard will allow, there are parameters you can install the Max hardware the Motherboard is compatible with.

Ideally, I would opt for at least 400w PSU. Sometimes It will stipulate on the Graphics Cared box or the website. Look at the specs/System Requirements here:

    I think it will work, maybe not to it's full potential, but it should work.

SOURCE: Hello, I have a T5500 with 2 x Nviida Quadro FX580


3 cards, all from Nvidia, will work together in a system without big conflicts. If you had Nvidia card and one ati card then you would have problems.

It depends on the motherboard, of which I haven't found details yet. But you can place the new card in the X16 slot, the 2nd card in the 2nd x16 slot and the 3rd will work on the x8 slot aslong as the connector fits.

Can you see a model / brand on the motherboard when you open it? I couldn't find its details from dell so far to confirm.

Try contacting Gateway, their technical documents do not specify. There is a lot of cross compatability in PCI-E, most of the issues come down to power requirements.

I wanna know what video cards will fit my DC7600 convertible minitower

Your PC has a PCI-e x16 slot available for upgrading graphics cacapabilities. Any PCI-e x16 that is not double-slot wide or that requires a pcie power plug should work. If you take a look at the images at you can see which NVIDIA (Geforce) and Radeon based cards are double wide. Your PC just doesn't have the physical space for a fit. For Radeon cards 3000 series and below with the exception of not higher that an HD 3650 in the 3000 series. For NVIDIA based cards in the 7000 series and lower with a couple of exceptions. 8000 series: nothing higher than an 8600 model. 9000 series is a no go.
Your PSU is not capable of running the cards I mentioned as exceptions. Your PSU is less than 300W. Powerful video cards require more wattage and extra PCIe specific power connectors. Read the specs to ensure that the video card you are considering does not have any additional power requirements.
You can link to the cards you are considering and we will let you know if the will fit and work and why they will not if they are exceptions.

I have dell optiplex 755. Does my system support ati radeon 3650?. Also recommend me any else card which is suitable for my computer

what model is this small form factor ? mini tower?anyhow, here are the things that you may consider .
if its a small form factor unit then you may need to get a video card that is Low Profile
and also consider the power supply :
The ATI Radeon HD 4650 512MB Low Profile PCIe x16 graphics card should work fine with the 275w PSU.
Max power draw is 48 watts

I have gigabyte m68mt-s2p mother board can i install amd radeon hd6670 2gb ddr3 graphic card on my mother board

The Radeon HD6670 should work in the PCI-e x16 2.0 slot. The 2.1 card is backwards compatible with the 2.0 slot.

The only problem could be your case configuration (you need about 8.8" of clearance). You also will need to check if your power supply gives enough power to run the card and the other components. AMD recommends a 400W continuous output power supply for a single HD6670 card.

I hope this helps.

New motherboard GA-p67x-ud3-b3 no video on boot

  1. 1 x PCI Express x16 slot, running at x16 (PCIEX16)
    * For optimum performance, if only one PCI Express graphics card is to be installed, be sure to install it in the PCIEX16 slot.
  2. 1 x PCI Express x16 slot, running at x8 (PCIEX8)
    * The PCIEX8 slot shares bandwidth with the PCIEX16 slot. When the PCIEX8 slot is populated, the PCIEX16 slot will operate at up to x8 mode.
  3. 3 x PCI Express x1 slots
    (All PCI Express slots conform to PCI Express 2.0 standard.)
  4. 2 x PCI slots

HIS radeon HD 6750

Are you certain that your mainboard is PCIE 2.1 and not PCIE 2.0? PCIE 2.1 cards like yours will not work on a 2.0 mainboard (2.0 cards will work on a 2.1 board, however) If this is the case, you will need to get a compatible card.
If this isn't the case, have you tried this card in a different PC? It could also be that the card has a problem.
The last possibility is that there are power issues. A couple of possibilities:
  1. An external power connector (6-pin PCIE direct power to the video card) is unplugged. Check and re-test.
  2. Your power supply (PSU) doesn't provide enough power to your graphics card & the rest of your system. Check your PSU's specs against the specs for your card. HIS recommends a minimum 450W PSU, and I would recommend a good quality Antec, Corsair, or PC Power and Cooling or Cooler Master product in the 500W range for this card.
  3. You got a bad card, or else it shorted out, etc. during setup or installation.

Need a good video card upgrade for my HP a6658f... one that will fit in the space provided and not require too much power (300 watt power source). The original is starting to go, and I would like to...

Your system has, from factory a Benicia #IPIBL-LB motherboard and has a PCIe x16 slot. You could go with any card PCIe x16 that is within your power range. I personally like the Gigabyte, Asus, Radeon HD cards because you can get sound and audio out of the card, unlike the Nvidia cards. The card you would more than likely be looking for would be a midrange card going anywhere from 40.00 to 90.00. There are many to chosse from but, I would get one that is Windows 7 or at least Windows Vista ready. This AMD's site and this card would work for you. It requires
300w supply and would do a good job.

Is the video card PCIe compatible? I just assumed that by its age that it would be a standard PCI. I was wrong. Allan

System features of HP xw4400 Workstation on official HP web site state:

Expansion Slot
6 slots: 1 PCI Express (x16) Graphics slot, 1 PCI Express (x16 mechanically, x4 electrically), 1 PCI Express (x1) and 3 full-length legacy PCI slots

So it should work fine with modern PCIe graphic cards
