    Default What PSU for 4870 x2? (long read)

    Maybe I am not smart enough to grasp the inner workings of a power supply or maybe I am trying to cram too much knowledge into one day but I am completely confused in regards to upgrading my power supply.

    In the past, I simply went to newegg.com and sorted by top purchased power supplies and went with that but that doesnt guarantee me what I actually need.

    As such, I am trying to understand what I need but believe its just going over my head.

    Here is my question and a paste from another thread I made on a different site before being suggested to come here.

    Question:

    Which PSU would you recommend for the new 4870 x2's + a little overkill for the next generation or two of cards (I know its hard to guess because we dont really know what kind of leaps and bounds GPU's will make in terms of power consumption)?


    Was looking at getting this PSU atm...

    http://www.newegg.com/Product/Produc...82E16817139007



    From the other thread:



    The questions:

    Do I need a new power supply and if so do you have any suggestions?

    Even though extremely new, would any of you advise against the follow card?

    http://www.newegg.com/Product/Produc...82E16814102768

    The Background:

    Was looking at getting one of the new ATI 4870 x2's from newegg but will more than likely upgrade my power supply, which I have been looking at doing anyways.

    However, based on the following link it doesn't seem as if I actually need to upgrade the power supply. If there is one part or aspect of a complete that I could say I have the least knowledge it would have to be the power supply. So any information is helpful.

    http://extreme.outervision.com/psucalculatorlite.jsp

    It tells me I will need a 499w with 20% aging. However, I have already had my power supply for a year or longer. Dunno how that equates into it. As well, there isnt a current selection for the newly released 4870 x2 cards, just the standard 4870.

    This is my rig as it stands now:



    The rig has 6 onboard USB ports and an additional 2 in the front totaling 8 ports. I only use the 6 in the back atm.

    • Port #1 - External 60 gb 2.5" HD (Powered through USB)
      Port #2 - USB 8 Port Hub externally powered (Mouse, Wireless Keyboard, Headset, Flash Drive, 360 Wireless Gaming Receiver)
      Port #3 - Digital Camera USB (Only used to upload pictures of course)
      Port #4 - USB Cable for Harmony Remote (Only used to download new settings or firmware)
      Port #5 - UPS
      Port #6 - Think this one might be empty, not sure.


    It has two Ethernet powers but only one is turned on and in use (the other is turned off in the bios various IDE functions since I only use SATA).

    Additionally, this is all hooked to my Samsung 46" TV via DVI-HDMI and through the X-Fi front bay to my 5.1 home theater.

    As far as the card is concerned, I play a lot of FPS's and MMO's. Currently playing WoW, AoC, CoD 4, Unreal 3, TF2, soon to be CoD5 and hopefully PWI, WAR Beta and or Live. I ALWAYS keep the resolution at 1920x1080 and generally max everything out which I why I am looking to upgrade, just need something more powerful. Although with AoC and its completely bugged/poorly coded software I have to keep things a smidge below max.




    Last, sorry for the long read but a huge thanks for any help. Also, any articles out there that you all may be aware of that can help educate me in regards to power supplies would be great. Am googling info but some of its just flying over my head.



    Edit: Btw, I am not on a budget as far as the power supply goes. If I get anything, I might as well "future proof" it as power supplies doesn't see drastic changes from year to year.

    In addition to that wall-o-text, I am trying to wrap my brain specifically around rails. I have read a couple articles on this page two or three times and am still confused. So at this point I might as well just get PSU suggestions and try again to read the articles at a later date.

    That HX520 should do the job, but it gets too loud during load, it might be a good ideea to change it.

    Yeah, read that first thread a couple times. Think I am trying too much, which I know nothing about, into too short of a time span. lol

    I guess my real question is...

    Whats the best bang for the buck in terms of overall quality for someone who will never run SLI or Xfire but does want something that is going to last for at least the next 1-3 generation of GPU's?

    I think a future flagship GPU won't consume more power than an R700(HD4870X2).
    It's been a hard day's night and I've been working like a dog.

    Hrm, if that is the case and I cannot see myself ever using xfire. Maybe it would be easier and cheaper to go with something around 850w.

    Any suggestions for a high quality 850?

    I don't think any CWT PSH based PSU over 800w is a great unit.

    Oklahoma Wolf seems to disagree. He gave the Hiper a 9.5 Performance score.

    It isn't like the OP will ever run the PSU even near its capacity in the first place.
