Common Applications
The TBBZQ is an expansion backplate that fits behind Intel LGA1150, 1151, 1155 and 1156 motherboards to spread the clamping load of a heavier brass or copper CPU water block. The plate is stamped from 1.5mm carbon steel and is supplied with double-sided insulation pads that sit between the metal and the rear of the PCB, preventing contact with solder joints and traces. It replaces or augments the stock plastic backplate so that screws torqued through the block do not flex the board over time, which keeps cold-plate contact even and reduces stress on the socket area. Mounting hardware from the matching CPU block is reused; this part ships as a bare reinforcement plate.
Frequently Asked Questions
Q: Which sockets does it fit?
A: Intel LGA115x: LGA1150, LGA1151, LGA1155 and LGA1156. It does not fit LGA1200, LGA1700, LGA2011 or AMD sockets, which use different hole patterns.
Q: What is the backplane made of?
A: 1.5mm carbon steel, supplied with double-sided insulation pads to isolate the plate from the back of the motherboard PCB.
Q: Do I need this if my CPU block already came with a backplate?
A: Only if you want extra rigidity for a particularly heavy block. Stock plastic backplates flex more than steel, so an expansion plate is mainly useful for brass full-cover blocks or vertical-case orientations.
Q: Are screws and standoffs included?
A: No. The TBBZQ is a bare reinforcement plate; you reuse the mounting hardware that came with your CPU water block.
Q: Will the insulation pad prevent shorts?
A: Yes, when fitted correctly. Peel the backing, align the pad over the steel plate so it covers the side facing the PCB, and check that no bare metal touches solder points before tightening the screws.
