Thortech Thunderbolt Plus 1000W Semi-Modular Power Supply Review

A Closer Look – Interior


The OEM for Thortech’s Thunderbolt Plus 1000W PSU is High Power/ Sirfa. The PSU is based on a slightly old design that doesn’t feature any advanced new power delivery topologies – like LLC resonant converters for example.

The provided fan is 135mm in size and made by the OEM Globe Fan. The fan part number is RL4Z B1352512H-3M.

The two main hold up caps are both made by Rubycon and are rated for 390 uF and 400V each up to a maximum operating temperature of 105 degrees celsius.

Transient filtering starts at the AC receptacle with one X cap and two Y caps.

The transient filtering continues onto the main PCB with one X cap, two more Y caps, two CM chokes and an MOV.

Large black heatsinks provide cooling for the two parallel bridge rectifiers hidden beneath.

There are no additional filtering capacitors provide on the modular PCB but there are Japanese Chemi-Con capacitors scattered all across the main PCB, rated for 105 degrees Celsius operation.
