Greetings once again, loyal readers. As you can see by the above picture, I'm taking on another power supply for review today. This time, it's Thermaltake's brand new Toughpower XT, a line of units featuring things like single 12V rails, 5 year warranties, and 80 Plus certification.

This particular model is the W0230RU, an 850W unit that comes in with 80 Plus Bronze certification.

With the Toughpower XT line, Thermaltake appears to have spared no expense on the packaging with the front of the box opening up to reveal marketing the likes of which I haven't seen before here at the site. It's almost like a new Lego set, except instead of looking at all the cool Lego pieces under the lid all you get is marketing, marketing, and more marketing. And what do all these marketing blurbs say? Why don't I just reprint it all here:

  • 12Vin1:
    As the +12Vrails deliver the major power to many of the components in a modern PC system, it is important to ensure each +12V rail provides adequate current for the relevant components. Inadequate current in any rail or poor distribution of current among the rails may lead to serious compatibility problems. Thermaltake understands your worries of the compatibility between PSU and your system, so we implement a pure and powerful single +12V rail to provide the best compatibility for your PC.
    -oh, man... where to begin. Friends, a properly designed and well built PSU is a properly designed and well built PSU, regardless of 12V rail topology. I know single 12V designs that suck lemons, and I know sextuple designs that utterly rock the house. The key is to do your homework beforehand and buy a unit appropriately sized to your hardware needs, and you will find that for the most part the unit's designers have done their job properly, whether your target PSU is single 12V or not.
  • High Quality Japanese Capacitor:
    Capacitors play very important roles in a power supply unit. Poor capacitors may lead to shorter life time, system instability, voltages fluctuating, and even damage the power supply unit. Toughpower XT series, built to the highest standard of quality, has implemented the high quality capacitors on the primary side and also the secondary side. All the high quality capacitors in Toughpower XT power supply units are Japanese-made and have the highest level of workmanship.
    -while this is all pretty much true, they left one out here. Failing capacitors can also increase ripple and noise, because they can no longer suppress it properly. But you'd have to be running a poorly built unit with "out of the back of a white van" capacitors to worry about that much these days. Many second tier capacitor brands like Teapo and Samxon actually do pretty well in computer SMPS use.
  • S.P.T. Indicator:
    Traditional power supplies tell you nothing about the status of your PSU so users find no way to protect their PSUs against failure. To help you monitor your power supply, Toughpower XT series utilizes S.P.T. indicator to indicate the standby mode, the power good signal, and the temperature of your PSU, bringing you the real-time monitoring over the power supply.
    -I expect this is somewhat more useful than the less common S.P.I.T. indicator, which only tells you if you're suffering from dry mouth.
  • S.F.C. Quiet:
    Noise can be annoying and even harmful to human health. To bring the best comfortability to users, Thermaltake's designers minimize the noise generated by our products to the lowest level. All Toughpower XT power supply units' 14cm dual ball bearing cooling fan is equipped with S.F.C. Quiet technology so that the fan always operates at optimal speed (according to temperature inside the power supply unit) for the quietest performance.
    -I don't know about you, but I'm hoping those letters don't stand for Super Fighting Chicken. I'd hate to have a Peter Griffin moment up in here. I already have too many moments like that. Ladies and gentlemen, Mr. Conway... no, wait, on second thought, I don't think I should complete that sentence if I want to keep what's left of my sanity.
  • FanDelayCool:
    Thermaltake lab, after years of careful tests and experiments, has discovered many of the PSU failures are caused by the fan's immediate stop after powering off. To better protect your power supply, FanDelayCool, derive from high-end projector's cooling fan, enables users to control how long the 14cm fan should continue to operate (up to 30 seconds) after system shutdown. This is to assure all components inside the power supply to be thoroughly cooled off.
    -Whoa, whoa, whoa, whoa, whoa. Years of tests? Many failures? Projector cooling fans? Give me a break here. This feature is something I like, because the primary side of the unit along with the standby circuits is always up and running on most of these things, but this blurb is stretching things just a bit. If this unit is built on the platform I think it is (we'll see on page four), this little feature has been present on it already for years. You just couldn't turn the feature off, like this one claims, and more often than not it was undocumented. Moreover, the most heat susceptible components are the capacitors. A unit like this, using the good stuff from Japan, would never ever have to worry about a significantly shortened life span just because the fan didn't stay on after shutdown. It's a nice feature, but you won't trigger the End of Days if your next unit doesn't have it.

Moving down just a bit, we have... oh great. More marketing to type out.

  • High Quality
    As a new generation of ultra enthusiast system, Toughpower XT series has been built to the world's highest standard of quality, providing users with Thermaltake quality 5-year warranty for parts and labor. Besides, all the high quality capacitors in Toughpower XT power supply units are Japanese-made and have the highest level of workmanship. Engineers at Thermaltake lab have made every effort to ensure each Toughpower XT Series power supply unit satisfies our severe requirements for quality, durability, and performance.
  • Performance
    Toughpower XT Series power supply unit features a number of cutting-edge innovations that set it above the competition. New features such as FanDelayCool for thorough cooling, S.P.T. indicator, and 12Vin1 will all bring users the best performance. Besides, using exceptional quality materials and components has even made Toughpower XT Series qualifies for higher 80Plus efficiency standard.
    -just a quick note here... high quality and high efficiency are two different things. You can have one without the other.
  • Quiet
    To deliver a whole new user experience to users, Thermaltake's designers minimize the noise generated by our products to the lowest level. All Toughpower XT power supply units' 14cm dual-ball bearing cooling fan is equipped with Japanese 8mm bearing system and S.F.C. Quiet technology so that the fan always operates at optimal speed (according to temperature inside the power supply unit) for the quietest performance.
    -I'm getting deja vu all over again a second time twice. Seems like all we're doing now is repeating stuff from the top half of this thing here.

Sigh... at last, I'm done with the marketing, and can... aw, maaaaaaan!

  • High-quality Japanese-made capacitors provide superb performance and reliability
    -we'll see about that performance thing soon enough, as long as my fingers aren't cramped into painful useless clawlike appendages due to excessive feature re-typing
  • S.P.T. indicator indicates standby, PG signal, and temperature status of the power supply
  • FanDelayCool: FDC cooling function can be selected to adjust the amount of time the cooling fan keep running after after system shutdown
  • 12Vin1: single +12V rail provides the best compatibility for the latest components
  • Gold-plated connectors for superior conductivity
    -what is this, marketing by Monst... no, wait, I don't want to get sued... Mont-Starre Cable? We're looking at a power supply, not a $600 audiophile electrical resonance flow facilitator (AC wall outlet) here. The reality is... your hard drives and motherboards in all likelihood do not have gold plated connectors. Why? Because it's not necessary. Like putting $5k rims on your lawn tractor.
  • Meet 80PLUS efficiency requirement: Eco-friendly design for the highest efficiency, least heat, and also lowers energy bills
    -sooooo... highest efficiency? You mean 80 Plus Gold status? Let me look at the box aga... nope, just Bronze. I know, I know, I'm nitpicking now. I get like that when I have to type out the whole Encyclopedia Thermaltakica word for word in a review.
  • TT5Years Warranty: Thermaltake quality 5-years parts and labor warranty
    -five year warranties are good
  • 14cm ball bearing cooling fan with Japanese made 8mm bearing system

Whew... now I'm done.



This is a computer Power Supply. Please refer to our official website for detail product information.


Dies ist ein Netz... you know, I'm just going to stop right here and get on with the review. Hope you folks don't mind. You, uh, can all stop cheering now. You, there, put down the pitchfork, noose, and torch.

Another box shot.

Another box shot. This time with a bunch of cool graphs, tables, and pictures. Can you believe we still haven't gotten out of the box shots yet by now? They're really marketing the bejeezus out of this new line, aren't they?

Oh goodie... the box has another box inside. I wonder if this is the Thermaltake equivalent of a Russian stacking doll.

Ah, at last! We're finally getting to the actual power supply!

As was the case with other recent Thermaltakes I've looked at, this one comes with a bunch of cool stuff in the box-within-a-box. Power supply, modular cables, "Key 3 Spirit" warranty thingie, a "thanks for buying this" flyer with yet more marketing hype for the XT series, a user guide you could use as a child's booster seat, a rubber gasket, three cabling adapters, some screws, a power cord, a velcro bag for the modular cables, velcro cable ties, a packet of silica gel, about a billion wire twist ties on the modular cables, a plastic bag, another plastic bag containing the modular cables, a bubble wrap bag for the power supply, two Ziploc bags, two big pieces of foam packing material, a box for the power cord, several motes of dust, and an extra molecule or two.

That should about cover it.

Oh, and a case badge.

You know, I'm not sure I see the logic for that marketing flyer being in the box. I mean, if you're looking at it, haven't you already bought this thing? 80 Plus certification is a good thing, but so is saving trees. All this marketing is more than a little over the top, methinks.

Here's the actual power supply itself. It's got that same off brown color Thermaltake likes that doesn't do a lot for yours truly, but the huge metallic sticker on the side looks pretty cool. And it was cool, until I realized I'd have to peel it partially off to get at the housing screws. So, you effectively have two warranty stickers to worry about on this unit.

Apart from the intake fan, there's only this little grille here for ventilation. It corresponds to where the capacitors are for the output.

Here are the modular connectors. Four 8 pin red ones for the PCI-E connectors, four 6 pin black ones for the peripherals, and one black 8 pin for the EPS12V/ATX12V cable. Although, why that one had to be modular I do not know.

Over there on the right you can see that S.P.I. indicator, which is really nothing more than a trio of LEDs.

And here's that FanDelayCool switch. You can disable the feature entirely, or set it for 15 or 30 second durations.

At last, the load table label. At a total 12V rating of 62A, this isn't the most powerful 850W unit I've had my hands on, but it'll do. The combined 3.3V/5V rating, at 180W, is powerful enough however to run that old 5V based A7N8X mainboard you still use for folding. Hey, maybe that's why they made the ATX/EPS cable modular, you think?

The UL file number, e303666, tells us nothing about the OEM for it runs back to Thermaltake. But it didn't take much peering through the grilles to figure that out - it's Channel Well Technology, or CWT for short.

Thermaltake W0230RU 3.3V 5V 12V -12V 5VSB
30A 30A 62A 0.8A 3A
Max Power 180W 744W 9.6W 15W

Yes sir, the only hardwired cable on this unit is the main ATX connector cable.

Here are the modular cables. Pretty standard CWT stuff. The PCI-E cables all have those ferrite beads on them that have never really proven they actually do anything.
