    Linking two XFX power supplies?


    Hey guys, my mate has bought one of these:

    http://www.amazon.co.uk/XFX-Limited-...s=xfx+pro+1000

    He is planning to make a 2500 system, and he realised 1000W might not be enough (Tri SLI, a few hard drives).
    We're both wondering if you can link two of these supplies together, as you can with (I think) the Corsair AX1200?
    Any help would be appreciated,
    Dom

    You can, but it is not an easy "just plug it in" affair. You need to do some re-wiring and understand certain circuit functions.

    If you google it you will get many how-to sites. Best to read up and determine for yourself if you are up to it.

    Wouldn't it be easier (and cheaper) to buy a, lets say 1500w psu? 2000w is pretty overkill too if you ask me, unless you are running with 3 very high end GPU's like GTX Titan.

    You cannot simply connect the appropriate wires together and expect the PSUs to automatically share the load. They will not. The typical result will be that one PSU supplies virtually all the load and the other essentially nothing. I won't go into the details of why this is so but it will be understood by anyone who understands how regulated PSUs work.

    To make this work you need special external hardware or PSUs specifically designed to work this way.

    Be sure you understand that even high end computers become obsolete very quickly. That high end gaming computer will soon become quite ordinary and sub-standard not long after that.

    Go plot your friends specs into this calculator and see if 1000W is enough, it might be.

    The point is, he has already bought the power supply. He wants to keep it, and having the ability to just buy another and link them together would be more appropriate.

    Buying a different power supply could be an option though, if amazon are willing have it returned purely because the guy doesn't want it.

    Anyway, thanks for the suggestions. Will show him this thread :)

    (Background story: Was originally going to upgrade his current PC, and bought the power supply. Decided he might as well start from scratch and use the power supply he just bought instead of buying something like an AX1200)

    You're welcome mate.

    I'm pretty sure that they will take the PSU back if 14 days haven't passed since he bought it :)

    And yeah show him this thread, and make him try the PSU calculator that I linked, it is quite accurate and with some luck a 1000W PSU might just do the trick.

    Take a look at this (there's also a video to show you how it works): Add2Psu | Connect two power supplies easily and safely


    However, the best solution still remains and that is to use a unit that is powerful enough in the first place.
