A huge number of them. You can even buy an uninterruptible power supply (UPS). I advise you to choose from quite well-known brands such as AEG, APC.
Most consumer surge protectors (at least for the US) are not rated for more than 1,800 watts and given the 80% rule it wouldn't really be a good idea to max one out. If you have a lot of mining rigs, it is not really need to use UPS devices as you will likely never break even on them unless you have power outages all the time. The only UPS devices that handle 2000 watts require 30A circuits.
OP - What country are you in and are you looking to hook up multiple rigs to a single power strip or a single rig consuming 2000w?
Also - You can't 100% rely on a whole house surge protector. They work, I have one... but if a device on a circuit causes a surge it can impact other devices on the same circuit as the surge doesn't get shunted before it gets to the panel.
240v - If you are in the US and running 240v... you will need to find 240v power strips. For example:
