    Well, you don't seem to understand fully.
    They don't really consume more power than the connected hardware demands. On the other hand, they have an amazing efficiency rating, meaning that they use a minimum of power, and are therefore better for the planet. ;)

    I respect mother earth and her well-being; I will never hurt her by accepting these gluttonous monstrosities in my gaming builds. Low budget/ low power/ high efficiency FTW!

    Where is the EVGA Supernova P2 series? Would have been nice to see it included. :)

    Much better PSU review than usual for THW.

    However, none of these PSUs are as interesting as the SF Leadex.

    Agreed! That's why I wanted to see the P2 here.

    Pity the Thermaltake Toughpower XT Gold 1475W wasn't included, I've obtained
    half a dozen of them recently, excellent PSUs.

    Cooler Master really stepped up their quality in PSU's, can't ignore that.

    I still like the interior of my Antec TruePower Quattro 850w. Massive heatsinks!

    About that Antec 1300w PSU, according to their site, it says that has a "20+8-pin MBU socket for the needs of tomorrow."
    Do you guys have any info on this?

    "At the time of writing, the website Plugloadsolutions.com only lists 7 Titanium-grade PSUs: Six models from a company called ‘Super Flower’ and the Corsair AX1500i"

    Wow, way to discredit yourself completely. You're reviewing power supplies and you've never heard of Super Flower?

    Not so sure about that. What they did was order a top model from Seasonic for their flagship power supply. No guarantees the rest of the product line will come from Seasonic. If they don't, as they never did in the past, then they will have no relation whatsoever with the flagship product. This is why I never buy power supplies from brands, only from the actual manufacturers.

    True, but i was saying that compared to their other series, like the SilentPro and GX series. But still even if it's not from seasonic they bench pretty good.

    I just don't get the idea of including a drawstring bag with the PSU. What's the point? It's not like we often pull them out of the case and carry them around. I buy one, I install it in the case, and it stays there ( usually for years, ) until either it dies or I move it to a new case for a build. You want to include a bag or case for the modular cables, that makes perfect sense.

    the charts for typical use should be adjusted tfor these psus. they are not meant to be run at 500w and i dont think they are tested for such.

    If you only build simple systems, sure, but many people build something very different. Max RAM, many
    drives, oc'd 6-core, 4-way SLI/CF, etc. Mine is like that, and it's not even a particularly way out example.
    Also depends what you're using it for. My quad-580 is for CUDA research, whereas my gaming PC is
    just a 4-core i7 with two 580s. I use the top-end PSUs for custom video editing systems so they can
    support 4+ GPUs for lots of CUDA power, etc.

    I thought the same thing. Then I read this:

    "Using multiple graphics cards in a gaming PC is, however, a rare occurrence, as modern graphics cards are sufficiently powerful even for the most demanding games – there is simply no need for combining graphics cards via Nvidia’s SLI or AMD’s CrossFire."

    and the article went from suspect credibility to no credibility. Ignorant author is ignorant. Find another website to get a legit look at high wattage PSU's, apparently.
