A corsair gs500 psu wouldnt be eough for my system
The corsair CX 600 would be more than enough
For a system with a single GeForce GTX 550 Ti NVIDIA recommends a minimum of a 400 Watt or greater power supply with a minimum +12 Volt continuous current rating of 24 Amps or greater and with at least one 6-pin PCI Express supplementary power connector.
Select from reputable name brands like Antec, Corsair, Seasonic and XFX and you will be ensured that the all important +12 Volt continuous current rating requirement is met.
hey a corsair 500 psu would tht be a eoungh for my spec
amd phemon x4 840
4gbs of ram
i hecked how much i need says 477 watts so would a 500 w psu be ok
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) @ 50°C ambient temperature, is the most important factor.
The Corsair Builder Series CX500 V2 (CMPSU-500CXV2), with its combined +12 Volt continuous current rating of 34 Amps and with two (6+2)-pin PCI Express supplementary power connectors, is more than sufficient to power your system configuration with a single GeForce GTX 550 Ti.
Thermaltake's various Tough Power series are the only ones I would, maybe, consider. Although only certain models that have undergone a test review by a reputable review site are the ones I would evaluate.
I would stay away from the Lite Power series because the shorter than industry average warranty serves as an indication of its expected reliability. Their combined +12V continuous current capacity is also less than that of a reputable name brand PSU of the same wattage, hence the series name Lite Power.
