I have an old power supply with the following characteristics:
PORSCHE Model: P4-450W, 20+4 pin connectors
Recently I am assembling a new PC with the following parts:
GPU: Gigabyte GTX 1080
CPU: Intel Core i5-6500
Motherboard: MSI z170A
RAM: DDR4 2800-16GB
Is my old power supply enough for my new PC or I should buy a new one? What are the possible effects of using the current old power supply?
