i need more power LOL

Any powersupply can be run in series. You just need to take some simple precautions

First the obligatory WARNING: do not attempt if you are at all unsure. Following this advice is at your own risk. 80v is deemed a dangerous voltage and should not be worked on without assistance [its one reason why phone systems are 50v - so they can be worked on by a single engineer]

The key to stacking supplies is to ensure that the output of the supply is totally isolated and floating with regard to the chassis ground and mains earth. The lowest supply in the stack may have (arguably should have) its -ve rail connected to chassis ground.

Take the supply you wish to use as the upper one in the stack and make sure it is isolated from the mains supply and that the output capacitors are discharged by putting a low value resistor across them. Now measure the resistance from the each output rail to the casing and to the mains E terminal. if that is open circuit (at least >1Mohm) then it is ok to use. If not then you need to dismantle the supply to find where the connections are and isolate them. This is usually through hold downs for PCBs.

Once isolated it is simple them to attach the +ve output of the lower supply to the -ve output of the upper supply in the stack. The final output voltage is between the -ve of the lower and the +ve of the upper.

Be careful - safety first. High current DC supplies are more dangerous than AC!
