Seasonic was kind enough to send us a PSU in for our expanding list of testbeds. They shipped us their latest member of the M12 II line: a 620W modular unit. It's got three modular cables for SATA power (9 connectors), two for molex power (6 connectors), two for PCIe (1 x 6-pin + 1 x 6/8-pin) and one for floppy (2 connectors).

The unit itself is 80 Plus Bronze certified which means that at 20%, 50% and 100% load the PSU will operate at a minimum of 82% efficiency. Expect to see it used in some of our reviews going forward!

    Don't be ridiculous - you're arguing for LESS content !

    If you don't wanna read the Just-Ins, then just ignore them - it's not a complex task...

    Well that's far from new... Its the original Corsair HX620W... Corsair buys this model, puts their stickers on and sells it overpriced.

    Uh no, this is a group regulated design. The corsair is an older independent design.

    So, um, are you going to review this PSU or are you just going to use it in reviews for other parts?

    This is 8* the power you need for a non-gaming PC and 4* the power for a gaming PC. (It's not marketed for servers.)
    Stop this nonsensically huge market for overpowered PSUs.

    Sorry, but that's completely wrong. An average gaming PC idles at around 120W, but at full load you can easily hit 250W. (That's with something like an HD5770.) If you want a more potent gaming PC with an HD5870, load power draw can reach 400W. 5870 CrossFire or -- Green-mongers help us -- the GTX 480 SLI will tip the scales at over 600W (or 850W in Furmark for GTX 480 SLI).

    Since ideally you get maximum efficiency at around 50% load, that would mean you should grab a 620W PSU for a typical gaming PC, or one of the crazy 1000W+ units for GTX 480 SLI. Is it a small portion of the overall market? Sure, but these days you wouldn't find me buying anything less than a ~600W unit.

    My relatively modest machine can use up to 300w on its own, more when I had my 2900XT and several other cards for multiple monitor outputs

    But, I have to comment. I LIKE the "Just In" articles.
    -- It's part of what is new (reviews don't happen instantly)
    -- It let's me know what reviews are coming
    -- It is a snapshot in time of the reviewers interest and thinking; sometimes most revealing

    It's odd that so many IM and Tweet and Facebook etc but they don't like more instant information here.
    It's not like Anandtech stopped doing reviews, it is just more timely updates along the way. Kinda like technological "road signs".

    And I guess if you don't like them, don't read them. They are, after all marked "This Just In" as the first three words....
