    It would be very tight. What brand of PSU do you have? Is it a stock one that came with your computer?

    Might just want to drop about $65 or so on a new PSU just to be safe.

    Edit:
    Wow, here is an OCZ StealthXStream OCZ600SXS 600W for $55 and it comes with a free 4 gig flash drive.

    And any reason you want that exact card? I am really considering one of the just released but hard to find HIS cards with the ICE coolers:
    it is the blue ones, and there are 4 different models:

    One of them is even $176.99 after rebate

        I had that very same exact card (and in fact, my 4850 is for sale in the Buy/Sell/Trade section... ;) ha!) on a 450W stock Antec PSU. It ran just fine. However, I tend to agree that 420W is really pushing it. I would also recommend a more powerful PSU.

        Especially considering I tried the 4870 on the same PSU and it would konk out. So I needed to buy a new one. I only bought (felt I needed) a 500W PSU but there are better deals out there than the place next door to my apt. I was going to go for a CoolerMaster 520 (or so Watt) one, but the two 12v rails the 4870 needed didn't have enough combined amps to run the card reliably. This one had the necessary AMPs

        That's just me relating my experience. I don't have a PSU recommendation that's what everyone else here is for ;)

            Dead_Meat, could you post what the amperage on the +12V rail(s) is on your PSU?

            Amperage is what you need to concentrate on more when you try and decide if your current PSU can handle a new card.

            Use the eXtreme Power Supply Calculator to help you get your possible amperage needs on the +12V rail(s). It's fairly accurate if you select the right settings.

              if i get a 600w power supply will that be big enough for me to upgrade my system to a quad core with vista and 8 gigs of ram here in about 6 months or so?

                    I'm not one to gamble with them but my brother is running an AMD 6000+, 4GB of RAM and 2 8800GTs on a 550 watt Antec so you might manage to get by. Just don't get too upset when your PSU goes out and takes half of the rest of the computer with it.

                      Re: power supply needs for a video card

                      I am running a quad with 4 gigs of ram and an 8800GTS on 620watts Corsair PSU, so I think a 600watt OCZ should be good.

                      As far as the card at newegg, I posted the link to ZipZoomFly because they have all 4 models to choose from, and actually have them cheaper than Newegg. ZZF is a very good company right up there with Newegg. Newegg did have all 4 models, but for some reason they cut it down to 2 models now.

                        I forgot to mention that the "free" version doesn't give you amperage for the +12V, +5V, and +3.3V rails.

                        If you can jot down in a post the exact parts you want in your new rig, I can post the amperage and wattage you need for that particular rig. I'd be calculating based on a worst-case scenario (100% system load and 100% CPU load).


                        I can say right now that 18A on the +12V might not cut it especially if you get a X2 card or SLI/Crossfire. (Those rigs can draw somewhere from 19A to 30+A on the +12V rail(s).)

                          now i'm pretty sold on a new power supply i just want to make sure its big enough i dont have to replace it again to soon
                          need a new video card now i just bought the new stalker game and this card wont run it

                          later i may go to vista and a quad core processor (which i may buy a new mobo when i do) and go for the 8 gigs of ram but i probly wont do this for at least another 6 months (i want to get a 24in monitor first)
                          so if that 600 w will be enough its a good price or should i get a 750 w supply

                          here is a 750w psu i was looking at

                            As Bamboo said, the Corsair PSU's are very nice. I have the same 620w version in a Quad core system.

                            The one you linked to is nice and will run most moderate to high end systems fine. It has a nice big fat 60amps on the 12v rail. The 620w I believe has 48amps and has been shown to be able to handle 8800GTX's in SLI. The difference though is the 620 model is modular where as the 750 is not (cables detach that aren't used). Not a big deal though.

                              LongBow is correct, the Corsair you linked to is pretty popular.

                              Thing is, you are thinking about getting a 24" monitor soon? The native rez on a 24" monitor is pretty high. You might really want to be looking at a 4870 or 260 gfx. card, or you are going to be hurting when you get the 24". If you do end up with the 4850, you might want to consider getting the 1gig memory version of the card, as running a high rez screen is the only time it shows what the 1 gig is helpful for. If you stay with like a 22" or smaller, the 512mb ver. is fine.

                              There is a 1 gig version of the HIS ICE card we talked about above.
