    Default Is the Thortech Thunderbolt Plus 1200W really that bad?

    Overclock3D Review >> http://www.youtube.com/watch?v=MCuKM6Ux4B4 (Check 4:30 sec's onwards - 2 PSU's failiures in the video, terrible ripple)

    Kitguru say otherwise >> http://www.kitguru.net/components/power-supplies/zardon/thortech-thunderbolt-plus-1200w-psu-review/7/

    Techpowerup say otherwise >> http://www.techpowerup.com/reviews/Thortech/TTBPK20G/9.html

    Not the worst unit ever, certainly, but still pretty mediocre for the price.

    Overclock3D isn't exactly the brightest, they overloaded the 5v & 3.3v rails on a NZXT Hale90 750w unit, and originally failed the unit because it wouldn't operate properly under those conditions.

    I Agree with Tator Tot.

    You shouldn't care about OC3D, they don't really matter. And I don't think they get as much samples as other sites do...

    The Thunderbolt isn't a really great unit or even the best in the world. But it's not total crap that will fry your Computer either (well, if there is a short, than maybe)...

    Buttom Line:
    If you already have it, it's OK but if you don't already have it you should go for another unit.

    It's not a good 1200W, but you probably don't need a 1200W so it's fine if you like the iPowerMeter gizmo.

    Use it if you already have one. Get away from it if you are buying one.

    Not going to buy one, I just came across it out the blue while on youtube.

    I just found it somewhat bizzare, when other reviews say it was okay, I guess Overclock3D got a couple of dodgy ones, maybe they pressed a few wrong buttons.

    The latter is more likely. Their PSU tester guy doesn't seem to know how to work the load tester correctly, as seen in many of their videos.

    I meant the Thunderbolt Plus is OK but better choices are available at this price.

    Like what you found in several reviews, it's not the worst at all.

    I have one of these in my hands now.
    Pretty bad ripple on all rails. It originates on 12 V, around 235mV at 1.1kw. It feeds right through the DC-DC bits and comes out the other end of them. 5 V is also at around 235mV while 3.3 V is at right about 250mV.
    Even at low loads it's over spec. All transients. This is my first unit we're talking about, I imagine it'll be going back (after I take some pics of the guts). I'll let y'all know when I get another or if the company says "Meh" to my request for another (like the Tt Smart-M 1kw, for instance...).

    Previously I had a non-Plus thunderbolt. It had extremely similar issues to the Smart-M's, though only the 12 V rail, it hit 260 mV at mid range loads hot. At full load it was ~10% over spec on all three rails. They took it back and sent the Plus that they had meant to send in the first place (PR is in Taiwan, shipping is in california)

    I think the bottom line is that I wouldn't buy a 1kw+ Sirfa unit. Three for three on too much ripple. Like I said I'll post further results when I have 'em.
