Thortech Thunderbolt Plus 1200W PSU Review


The Thortech Thunderbolt Plus 1200W box is large and heavy. The top of the package has two carry handles which are made from a felt material.

The top of the box opens up to reveal the power supply underneath thick foam padding.

The contents are extensive. The modular cables are stored inside a felt bag. There is also a regional specific power connector, the iPower Meter, mounting screws and a bag of cable ties to help with the installation phase of the system build. The company also supply a ‘quick installation guide', which is a basic user manual.

The iPower meter can be installed inside a 5.25 inch drive bay and offers read out values for power consumption, voltages and efficiency. It can also list temperature and the speed of the fan in RPM.

iPower Meter also can adjust the fan to one of two speeds, ‘quiet' and ‘full'. Quiet mode is based on PWM, and related to internal temperatures. Full mode spins the fan at 100% all the time, regardless of internal temperature.

We would advise to leave this on the standard quiet mode. We think this is a cool addition to the bundle.

Thortech supply a felt bag which opens up to reveal the modular cables.

Above left are the modular cables, and above right – the hardwired cables which emerge directly from the power supply chassis. We would have liked to see less hardwired and more modular cables however.

All of the cables are sleeved to high quality (18AWG).

Cable Amount
MB 20+4 pin x1 (530mm)
EPS12V 4+4 pin x1 (580mm)
EPS12V 8 pin x1 (580mm)
PCI E 8 pin (6 pin +2) x4 (hardwired – 580mm) &
x4 (modular – 580mm)
Sata power connectors x4 (hardwired – 580mm + 150mm)
x8 (modular – 480mm + 150mm)
Peripheral 4 pin (molex) x6 (530mm + 180mm)
Floppy connector x1 (180mm)
iPower Meter 6 Pin x1

There are no shortage of cables with the Thortech Thunderbolt Plus 1200W, much as we would expect in this price range. This supply can cater to the most demanding of systems with up to 4 high end video cards. The 20+4 pin cable is a little short for such a high end 1200W power supply however, as are the EPS connectors. 650mm would be an ideal length for super tower cases.

  1. Not bad, but yeah its outclassed by others, so the price needs to drop to reflect that.

  2. If anyone is buying this, I recommend AMAZON as they have a great returns policy,. I dont know how the warranty would work in the UK

  3. for those who dont know, this is under the ‘GEIL’ umbrella……

  4. This is one of the worst power supplies ever made it literately has so much ripple it will ruin all your components. You have lost any credibility with me saying this is worth considering. Look at what TTL customs / overclock3d said on this for actual honest indepth review.

  5. James – seems to get quite a lot of good reviews on some sites too. Techpowerup reviewed it and it did well.
    http://www.techpowerup.com/reviews/Thortech/TTBPK20G/

    Looks like a decent PSU to me.

  6. James you are using overclock3d as a guideline for PSU reviews? wise up dude. Techpowerup reviewer is much better than them. havent read an OC3D PSU review in some time as Tom talks shit.

  7. Look if you overclock alot ripple is the one of thoses things you must totally avoid otherwise components get wrecked. Iv seen it first hand its totally observable its based in standard electronic engineering. If you wanna buy it go ahead but if you need 1.2kw psu you shouldnt cheap out because you going to have alot of tech on it. I have a 1.2kw enermax platimax for very good reason.

  8. My friend has this and its fantastic, had it since March this year. two 580s in SLI and rock solid!

    People dont understand the results in many PSU reviews, thats the problem. then we get a guy making a video who maybe had a bad one and everyone thinks they all blow up.

    I trust techpowerup and Kitguru over that.

  9. I agree this PSU has problems, techpowerup recorded fairly high ripple, like this review but its well within the rated specs listed by the industry. thats not an opinion, its a hard cold fact by the industry who set out ripple ratings.

    It is possible to get a bad power supply, ive had 2 corsair AX units fail on me, but they get great reviews and I haven’t stopped buying them.

    ive been reading techpowerup for years and CRMARIS is very good. his results are different to Kitguru, but close, especially with ripple. its all within spec.

  10. ENERMAX? I wouldn’t trust them to power my toaster. THEY ARE A NIGHTMARE TO GET REPLACEMENTS TOO!. don’t believe me, check out some threads http://www.google.co.uk/search?client=opera&q=enermax+failures&sourceid=opera&ie=utf-8&oe=utf-8&channel=suggest

    They are a disaster.

    Seasonic for me all the way, Enermax suck.

  11. @ James “Look if you overclock alot ripple is the one of thoses things you must totally avoid otherwise components get wrecked” – are you for real or having a laugh?

    Where did you read this? if it came from your preferred websites then you need to get a new reading source, because its total bollocks. EVERY power supply will emit some level of ripple. they have yet to make a power supply to produce 0 readings at full load on all +3.3V, +5 and +12V output rails.

    The rated parameters for safe ripple readings are

    +3.3V – no more than 50 mV
    +5V – no more than 50 mV
    +12V – no more than 120mV – applies to all, if there are more than one.

    So even if a power supply produces 90mV on +12v, its safe long term. its not ideal, sure, but things won’t suddenly ‘blow up’, unless you get a crap unit and it pops to 180mV. Most top class PSU’s are generally under 20 mV for +3.3V and +5 V at full load and +12V under 50 mV, but just because its a little more, doesnt mean they are dangerous. only if they break the tolerance guidelines set out by the industry listed above.

    In regards to this review, several sites have quoted very similar mV/ripple ratings which while far from ‘awesome’ are fine in everyday use.

    Before you start spouting crap best to get your facts right, otherwise you just sound like a total munchbucket.

    So much misfed nonsense in the power supply industry, such as people thinking a huge single +12V rail is the only design to buy etc.

    the only problem I have with power supply reviews is that these units are tested across a few days. ideally we would like to see 5 month long term tests in everyday use, b ut thats not logistical
