I recently bought a new computer consisting of an i5 3550, gtx 550ti, Intel spur lake z77 and 8gb 1600mhz ram.
My father bought the PSU and I would just like to know if it is big enough.
It is a Acabel 500w.
Is that 500 Watts continuous power or 500 Watts peak power?
For a system
using a single GeForce GTX 550 Ti
graphics card NVIDIA specifies a minimum of a 400 Watt or greater power supply that has a combined +12 Volt continuous current rating of 24 Amps or greater
and that has at least one 6-pin PCI Express supplementary power connector
Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Total Combined Continuous Power/Current Available on the +12V Rail(s) is the most important factor.
