    Re: PSU Question

    Peak load is not what I am looking for here, its sustained load. Its more high 12v Amps really.

    Re: PSU Question

    I think the point here is... ZOMG1000TW/h PSUs are simply not needed, they never were. Even a HX620 is overkill for 99.9% of users.

    Can you point me at a decent branded modular PSU that doesnt "give each component the proper power"?

    The two are directly proportional given the same voltages.

    well the corsair has 18 amps per rail and the Enermax has 28A to 30A per rail.

    Re: PSU Question

    Yes, over n +12v rails. This doesn't change the fact that Wattage and Amperage are directly proportional given the same voltage. Also, I find it highly unlikely that you would have a set of devices plugged in that uses more than 220W in 1 rail.

    Re: PSU Question

    aidanjt why are you arguing with me about amps?

    lol

    I am just saying that the way the PSU pushes the amps over the 12v rails is not directly proportional to voltage as this is to do with how they split the voltage across the rails.

    I am just thinking for SLI or maybe the next gen of DX10 cards the more guts the PSU the less the chance I will need to upgrade again next year. I hate pulling PSUs after doing all that work on sorting the mess of cables and wires.

    The HX620w looks like a very good PSU but in my eyes the 720W Enermax Infinity looks fantastic.

    there is also the SilverStone SST-DA750 that has a single 60A 12v rail

    Re: PSU Question

    I wonder how much of the information posted here is educated/factual/researched or just hearsay.

    There have been a number of good brands mentioned here. Pick one you like, don't worry too much about it, but do make sure you have a good surge protection or preferably a proper UPS between your PC and the wall.

    Your previous power supply was more than enough for your system, so would not have been stressed and should not have failed. Make sure you protect you power supply! I am starting to get the impression that most power supply issues are not related to a poor choice of supply, but lack of filtering/protection from your AC source.

    Getting an uninterrupted power supply (UPS) to plug your PC into will give it a nice clean source of AC, and I would not be surprised if it stops you having problems in the future.

    Good luck anyway

    No one else seems to be worried about the future, maybe all the experts, giving advice on buying corsair PSUs and similar, should review what they are saying......eh
    But if you have the money buy the best.

    Re: PSU Question

    Look, it doesn't matter if a PSU can output 200A on a 12V rail, you'll simply NEVER use that much on a single rail, the most powerful GPU on the market doesn't even use 18A, and if they start using that much then we should be seriously be thinking about not purchasing such inefficient beasts. This is the exact same thing that's been plummed to death on threads elsewhere about Wattage.
