Here we have a closer look at the 140mm cooling fan as well as a general shot of the internals. Thermaltake touts Japanese made electrolytic capacitors and solid state capacitors with low ESR which they claim greatly improve the durability and offer higher stability and reliability. It's also worth noting that there are two +12V rails. Most of the power supplies we have looked at either feature one large rail or several smaller rails.

Looking up the UL File Number E303666 points to "Thermaltake Technology Co LTD" as the manufacturer. Further research at Whirlpool reveals that this unit is actually manufactured by CWT, or Channel Well Technology. CWT has been making power supplies since 1993 for various "branded" manufacturers like Thermaltake, Corsair and Antec. CWT is generally considered as one of the better OEM manufacturers.

Thermaltake advertises the Grand 1050W as being 80Plus Gold certified for efficiency, which means they must meet a minimum of 87%/90%/87% efficiency at 20%/50%/100% of its rated load. The 80 PLUS Verification and Testing Report on the Grand 1050W reveals 89% / 91% / 88% with an overall average efficiency of 89.74%. This is a very efficient power supply; one of the most efficient we have tested, just behind the NZXT HALE90 750W.




Thermaltake includes a wealth of modular cables to use with the Grand 1050W. Rather than explain each one, I have included the chart above that shows the complete breakdown of each cable. The chart below shows each cable and its length.


Let's move ahead and get this unit installed in our test system.
