    Default Buying new Power supply

    So, I'm a first time poster, been reading many of the reviews here and it just makes choosing a power supply that much harder.

    My current power supply is an Antec SP-500, the one that came in that TX1050B (Yes, that's my case). But I have been looking at getting a new graphics card, notably a 4870, 2x 4870, or 2x4850 (Already tried one 4850 and felt I could use a little more with my 1680x1050 screen). Now, while the 500W might be enough for just one card, I want to leave myself the option of two even if I don't get two now. This is where my dilema comes in, I have no clue how much wattage I really should get, or what would be most worth it for me to get. I was looking in the 750-900W range, but I wonder if that's more than I need. I'd like to have this power supply last me possibly until they change from the ATX format, or when the PSU itself dies.

    So basically, I was wondering if anyone has any suggestions for me to look at. I was looking at mainly Corsair, Cooler Master, and Antec so far, but if there are any other suggestions for me, I'm all ears. If you need any of my specs in specifics, just let me know.

    What are you trying to power? What's your budget?

    A single 4850 is not enough for you at 1680×1050? That's..interesting.

    The single 4850 probably would be enough if I didn't like turning all the shiny features on...I was having a huge drop of frames in TF2 when i had settings up if I went to a firefight of like 8+ people.

    I also didn't really like having a card that ran at 80C, I could settle back to a 4850 in the end, but at least a non-reference cooler.

    My budget, not entirely sure there, extreme roof will probably be $300.

    I don't think the SP-500 has enough power for your system with the 4850. It may be running it for now but the card is unable to reach its full potential. You really need to get a better quality PSU. As odd as this sounds the Antec EA 480W will be a better PSU and should easily support your system. While its total wattage is lower then teh SP500 it puts more of its power to the 12V rails then the SP does.

    I was hoping to go with modular cabling, it is something I like from my SP500. My case has room for extra cabling to be laying around, but it would probably force me to add a second case fan again.

    The 620 sounds like it could be the best for me. How well would it handle if I ever decide to go with a 24" monitor and a second 4870. I also wonder if there is a newer version coming out soon, I know this supply was Corsair's first and wonder if as soon as I buy it an improved version comes out and I kick myself until the thing burns out (okay so the bruise will be large where I do kick myself...)

    The HX620 is a two-year old design, true, but it still stacks up well against all the competition when it comes to voltage regulation, noise levels, etc. Also, I can't comment on unannounced products of course, but I wouldn't worry too much. The HX620 is one of our best sellers, we'd be stupid to kill it anytime soon.
