Thermaltake ToughPower XT 775w PSU Review

Introduction & Specification

For me the toughest part of any review is the introduction. So much so in the case of Thermaltake that I actually wrote the entire review before coming back to write these few paragraphs you're reading now. But why? After all, Thermaltake are probably one of the best known manufacturers for enthusiast PC components worldwide, and if we're all honest we've probably owned something made by Thermatake at some point in our enthusiast lives. So it should be easy, right?

Nope. I'm still stuck.

You see, I think the problem here is that I can't delve into Thermaltake's past as a PSU manufacturer without sounding like I'm starting the review by ripping them a new one. Some of their early power supply's were quite frankly atrocious, and nipping in to your local enthusiast forum and letting slip that you had one inside your PC provoked a similar reaction to admitting you fancied a family member.

However, when Thermaltake released the ToughPower everything changed. For the very first time, you could openly admit to having a Thermaltake PSU to your online buddies and still retain your reputation for being a hardcore enthusiast. Thermaltake had woken up, got their act together and pushed out a PSU range that could give some of the best names in the industry a run for their money.

Today I'm going to be checking out the latest model in the ToughPower range, the 'XT'. So let's start by looking at the specs...

• Compliance with Intel ATX 12V 2.3 & SSI EPS 12V 2.91 standards.
• 24/7 @ 50 ℃ : Guaranteed to deliver 775W continuous power.
• Double-forward switching circuitry: compared with traditional circuitry, double-forward switching circuitry offers low power loss and high reliability.
• Unparalleled DC to DC converters for 3.3V and 5V outputs to reach high efficiency.
• High quality Japanese capacitors: ensure superb performance and reliability.
• 105 ° C (221 ℉ ) solid state capacitors: great stability at higher operating temperatures, frequencies and currents.
• 80 PLUS Bronze certified – provide up to 89% effective power conversion to cut-down electric cost.
• S.P.T. Indicator: PSU status monitor with 3-mode LED ( standby / PG signal / temperature).
• Fan Delay Cool Technology: allows 14cm fan to continue to operate 15-30 sec after system shuts- down to ensure all components are properly cooled.
• 2Vin1: single +12V rail design providing up to 64A.
• Multi-GPU ready: 2 x PCI-E 6+2pin & 2 x PCI-E 6pin for PCI-Express graphic cards.
• Active Power Factor Correction (PFC) with PF value of 0.95 at full load.
• Auto switching circuitry for universal AC input from 90-264V.
• High reliability: MTBF>120,000 hours.
• DIMENSION: 5.9"(W) x 3.4"(H) x 6.3" (L);150mm(W) x 86mm(H) x 160mm(L)
• Built-in industry grade protections : Over Current, Over Power, Over Voltage, Under Voltage, and Short- Circuit protection.
• Safety / EMI Approvals: UL/CUL, FCC, TUV, CE, BSMI, and GOST certified.

Looking at the specification list it's fair to say that the Thermaltake ToughPower XT has some pretty impressive credentials. There's the guarantee of 775w at 50°C 24/7, ensuring that the PSU wont drop below its rate output when the ambient temperature inside the PC case starts getting a bit toasty. The mention of DC-DC converters along with Japanese 105°C capacitors that should help provide clean, stable power. And the promise of up to 89% efficiency backed by an 80PLUS Bronze certification.

Furthermore, a full set of safety features is also listed for the unit with OCP (Over Current Protection), OPP (Over Power Protection) and SCP (Short Circuit Protection) all being be areas that will be tested for problems during the review today. Normally most units pass without any issue, but as I've often witnessed, even the most respected of manufacturers can sometimes get things wrong.

Thermaltake ToughPower XT 775w Rail Layout
DC Output +3.3V +5V +12V1 +12V2 +12V3 +12V4 +12V5 +12V6 -12V +5VSB
25A 25A 64A - - - - - 0.5A 3A
Max Power 150W 768W 6W 15W

Thermaltake have also followed the trend as far as rail layouts go by kitting the ToughPower XT out with a single 12v rail rated at 64A. This essentially means that the XT is capable of delivering almost all of its 775w output on the +12v rail alone. Additionally the +3.3v and +5v rails are capable of delivering a combined 150w with an OCP cap set at 25A on each rail.

Now the paper specs are out of the way, let's take a look at the actual product...

The XT may have 25w more power than its 750w competitors, but does it have what it takes to impress OC3D?

Stefan, I've been hearing mixed things. Apparently the website says silver, but the box most definitely says bronze

Maybe they re-submitted after the first batch went out. :/Quote
