We would like to thank Thortech for supplying the review sample.
The initials GEIL stand for Golden Emperor International, a really traditional and at the same time classy name for an IT company. GEIL is a large memory manufacturer that desired to enter the Power Supply Unit market but didn’t want to include the new products in their traditional memory related brand. So they used Thortech, a company with over 15 years of experience in this field, as a trojan horse to step into this market. Currently Thortech has only two PSU series and both of them include only units with high-end characteristics. The main difference between Thunderbolt and Thunderbolt Plus units is that the latter include a device called iPower meter, through which vital information about the PSU can be obtained. The Thunderbolt Plus series consists of four units with capacities ranging from 800W to 1200W and in this review the test victim will be a Thunderbolt Plus 1000W or TTBPK00G.
The TTBPK00G is 80 Plus Gold certified, has a single +12V rail which can deliver up to 83Amps, it uses a semi-modular design with rather many fixed cables, all of its capacitors are Japanese and the cooling fan uses ball bearings so it enjoys a longer lifespan compared to a sleeved bearings one. The unit shares the same compact dimensions with its 1200W big brother so it will not face any compatibility problems with most chassis/cases. Finally, like all Thortech Plus units its most fascinating characteristic is of course the iPower meter device which provides lots of interesting information including Watts drawn from the unit, efficiency, current, voltage readings per rail etc.
