    Not really, the Enermax Galaxy 1000W failed spectacularly when hooked up to Zardon's Skulltrail 8-core Triple SLI rig. The Corsair HX 1000W still runs it to this day.

    perhaps it was a faulty rig? The one review it has, says their quick to remedy the situation. So now you would say that corsair is better than enermax? Just an opinion. Im open for it LOL

    OK, now I think I misunderstood you. You specifically said low quality engineering(enermax)

    Yes, as the Galaxy 1KW is not the only unit that failed the test. The Corsair HX 1000 is a very good unit, but very loud. The Zalman ZM1000-HP wasn't tested with this rig, but I expect it can do the job, as my ZM850-HP can run a PSU stress test (not that I like to run it for more than a few seconds) drawing 1100W off my system. The HX1000 made some rather strange noises when I opened this.

    Would I be right in assuming the Zalman 850(128amps 6Rails) HERE
    would be a better value/price purchase
    than the corsair 1000(80amp 2Rails) HERE
    Wow, the zalman is looking VERY tempting!!!

    Hah, 128 Amps? The numbers add up, but the max output of the PSU as a whole will be about 66A. Either way, this PSU has no trouble powering two 4870X2s, and does it without making any perceptible noise. Most PSUs that can run graphics cards that powerful can be noticed as an extra frequency quietly audible in the background, or in the case of the HX1000, are louder than the graphics fans, clearly audible when both are at 100%. There's no noise I can detect as the ZM850-HP even after two hours of Left 4 Dead with 700W load. The thing is incredible. Make sure it fits though, it's more than 50% longer than a Corsair HX 520!
    As a product it only gets a 9/10 though, as the place where a power switch should be is instead filled by a pointless LED.

    Im not interested in Dual or quad Sli/Crossfire. I simply want a powerful single card that will last me a couple years like my 8600GT has. As ive said, im not an avid gamer. I just want a SHARP ENOUGH vid quality card. The 4870 seems to be the most talked about on the web!
    It looks like ATI recommends 500W for a single card. I should be safe then. if it takes 2 6 pins, and mine can offer 36amps combined, surely that'll be fine! Especially considering im not a heavy gamer! LOL

    A 4870 can really be run off a 450W PSU, but you'd need an adapter, which I am not fond of using.

    Yah...I dont even know about modular, let alone running adapters. Sounds like mickey mousing to me LOL! Besides, there has to be power loss there, if only a minor one. Probably not much but...

    Well, efficiency loss, it'd be very minor, but my main concern is the abysmal quality of the manufacturing in most power connectors like those.

    Yah...the very word adapter makes me cringe anymore! Most of my USB -->IDE adapters have taken a **** I'll be extremely selective in the future!

    sammorris I agree to an extent on the Corsair the 520 I received the fan was just hanging in it ,no big deal to repair but their rebates suck to high heaven.But you are definitely right for money and quietness they are hard to beat.

    I know maybe 10 people at my LAN party of 40 that I see regularly at the events that all use the 520HX, apart from one with a faster than usual fan, none of them have experienced any issues.

    That's the only Corsair I've had a problem with and I took that as something that slipped through. I seen a couple of other reviews after I bought it for fan problems including a yahoo who left some packing plastic in the fan.Not knocking the Corsairs for quality but their rebates are taking 3 months or more.That 520 is used on the new build that's being converted to home theater as soon as the price of quads come down a little more.Right now the tower sits next to my left ear and is playing movies with the only sound being heard is the movie and a little drive noise from the LG.The rebates should be illegal here in the states to!

    Corsair never were any good at rebates. The way I see it, they're a bit of a farse, which is why they're illegal in the UK.

    Thanks DDP!!! This calculator(http://www.extreme.outervision.com/psucalculatorlite.jsp) says I should be way good with my current PSU. I realize this is simply a guidline though. And that does mean that im running at 75% of load. When I upgrade to 4870 Video card anyway :)

    I might wanna consider going better in the fairly near future though. I dont like running over 50% load. Especially on a PSU that others think is garbage :(

    its only 1.5! I thought that was within reason. And the line size is proper as well.

    100 high and 3 lines. I didnt think that 148 and 1 line was extreme. Ive seen others with larger. Dont remember where. If asked however, I will acquiesce LOL (RULES)

    Sam, Wattage is more heat handling than anything, right? The thermaltake may have less power, but more Heat handling, correct? Ive read that more than once somewhere.
