    I hope you are going to get three of those HD7950, else I would just go with a SeaSonic X series 460 watt fanless.

    I plan on doing a 2x Crossfire eventually, however not at the time of initial purchase no, and seeing as how I am not really interested in dishing out a ton extra for a 3 PCIe 3.0 lane motherboard just to do triple Crossfire, I'd be happier with not gouging my hydro bill when using my computer

    Besides, dual 7950's in Crossfire will be more then ahead of the pack for graphics performance for quite some time, I am not too worried. And if eventually I choose to triple Crossfire, the prices will be a lot cheaper by then.

Eventually when I Crossfire two of those Windforce 7950's, I will want that case to deaden the noise of the fans, something my Define Mini does exceptionally well for my 6870 overclocked with a cranked up fan speed.

    Then you won't need anything more than a 550-650w PSU.

    Fair enough. I have a 750 watt Thermaltake Comet but I am going to sell it with my current rig when I upgrade. Odds are I will go for 650 watts just to be on the safe side then with this one:

    http://www.newegg.ca/Product/Product...82E16817151088

    I know it costs 10 bucks more then the HX650 from Corsair, but I would rather have the silent fan that the SeaSonic has.

    Yeah but it depends on the price differences whether I shop there or not. Some stuff is cheaper, and I probably will pick up the case from the NCIX store in Mississauga rather then have one ship from Newegg. Some stuff is cheaper even after shipping with Newegg, especially graphics cards. What it costs in shipping for most parts I will have to pay for in gas though so things like the case I will probably pick up. Since the prices are the same for the case, I will no doubt pick it up, cause 42 dollars for shipping is a lot of wasted money.

    I don't think I've ever paid more than $10 for shipping from NCIX.

    It honestly depends on whether any or all of these components will be overclocked.

    OC'd HD 7900 series ~250W
    OC'd Sandy Bridge ~130W

    That's already 630W without taking into account the rest of the system, and you really shouldn't be running a PSU at near 100% capacity for endurance and efficiency reasons. If he really plans on getting two high-end video cards, then I would suggest a 750W PSU minimum and more likely find him an 850W like a Seasonic X, Corsair AX, Kingwin Lazer Gold/Platinum, NZXT Hale90, etc. Or honestly because 80 Plus certification doesn't really matter that much, a Corsair TX850-M or NZXT Hale82 are absolutely fine.

    Nah. Using PSUs rated that high will reduce the expected lifespan, since it won't be at a significant enough load% while loading.
    650w is fine.

    Many high-wattage PSUs are less efficient at ~10% load, that's true, but that really won't reduce the overall lifespan of the unit. Let's use a generic 750W 80 Plus Gold PSU as a baseline.

    10% load = 83% efficiency = 75W DC and 90W AC ... 15W power --> heat
    20% load = 88% efficiency = 150W DC and 170W AC ... 20W
    50% load = 90% efficiency = 375W DC and 417W AC ... 42W

    Now a 550W:
    13.6% load = 85% efficiency = 75W DC / 88W AC ... 13W power --> heat
    27.3% load = 89% efficiency = 150W DC / 168W AC ... 18W
    68.2% load = 89% efficiency = 375W DC / 421W AC ... 46W

    The difference in heat output is negligible, so that cannot really effect component endurance.

    What can effect component endurance though is how many components are in the PSU. A PSU with bigger or more capacitors, transformers, filtering coils, VRMs, etc. puts less stress on each component. A PSU also tends to have its best voltage regulation and ripple suppression at lower loads... Voltage regulation is pretty much the most important factor for ensuring system stability while ripple suppression is important for ensuring the lifespan of those components.

    All in all, I want something that is modular, fairly to very efficient and gives me a certain amount of breathing room. Modularity and efficiency have a ballooning effect on the price of PSUs. On Newegg the Seasonic X-560 is $135. A Corsair AX750 is $150. They're both based on the same platform...

    I'd rather buy the same PSU at 650 for more money than the same at 750 if it fits the build better.

    If you are at or close to 50% in load, you will put long term stress on the PSU even though you will achieve less efficiency.
    The sweet spot for lasting is between 70-80%.
    That's why I recommend them.

    Of the two you linked, I'd rather pay 150 for the x-560 than 135 for the ax750 for my current build.

    @tetrisGOAT and how would one know if he is using his psu at 50-60 %?

    http://www.coolermaster.outervision.com/PSUEngine fill in values. 90% system load (only FurMark CAN make it 100%, and only if it runs a CPU-benchmark at the same time, ie, unlikely).
    Select GPUs with equal TDP-value if the ones you're using isn't there.

    Thank you very much.

    Edit. It seems that the minimum would be 350 w and im using a 650 W, guess its quite good :-?

    @Gottie4u amin to that brother but, as i can see you got a pretty nice gaming rig, why dont u invest some $ for a better case ( btw is that a thermaltake v9?).

    What is the basis for this 'sweetspot' of yours? 50% load is almost always more efficient than 70-80% in 80 Plus certified PSUs and more current = more wear and tear. Given that the current / power that is being utilized is the same regardless of PSU (other than differences in efficiency,) the 'stress' on the PSU is basically the same. Because higher-wattage PSUs of the same platform typically use more/bigger caps, transformers, coils, etc. the 'stress' on each component will be lower.

    I made a few modifications to my setup today:

    1. I got tired of my Air Penetrator intake fans noise and the fact they weren't PWM so ran at the same speed all the time, requiring resistor adapters to keep the noise down.
    To remedy this, I got a few Cougar Vortex fans (3x 140mm, 1x 120mm) and a Sunbeam Rheosmart fan controller that will take the PWM input from the motherboard and use that to control the voltage sent to the fans plugged into it.


    (wire management looks kinda messy but that's about as good as I could do without getting unnecessarily anal about it, mounted it in the back of that bay so the 120mm fan will still fit in the front)

    2. I finally jumped on the mechanical keyboard bandwagon. Got myself a Corsair K60, and I can't go back to rubber dome style keyboards for gaming again I will say I do kinda miss the backlighting from my G110 (which was starting to have problems with the "W" key not registering), but I wasn't gonna pay more for the K90 when that's the only extra feature I would have wanted and the different texture of the red WASD 1-6 keys help me find where they are just fine.

    (oh yeah, I also wall-mounted my monitor for more desk space)
