Corsair CX500 or EVGA 500B

Recommended Posts

i dont think that either is more reliable than the other but they are both from great brands. if one has a better efficency rating or one is more modular than the other one get that one. other than that you should be fine

Are you looking at the CX with the grey label? Those are better and around the same price.

Check for S12II seasonic. How much you want to pay for PSU?

Both are rather mediocre choices. You're better off with the Corsair CX450M/550M or the Seasonic S12II 520W if possible.

Be nice to each other boys and girls. And don't cheap out on a power supply.

Which one is more reliable in your opinion? Both are at the same cost. 


Both are OK, I'd personally get the Corsair. Is the CX450M not an option for you?

Thanks for the input, trying to keep 500W to power a GTX 670

Corsair cx power supplies get a bad rep due to their cheap construction. psu reviewers like Johhnyguru commented on their poor holdup time, but in other metrics, it was average. The biggest letdown is the temperature rating, these psus are only rated at the specified wattage at 30 degrees celcius, which is way below the operating temp in most pcs. As far as I can work out, at  the higher temps, it cannot reliably output the advertised wattage. I am running a cx600m on a rig that should only draw around 450 watts max so i hoping I'll be fine. It's been like this for over a year and I haven't had any problems. These are budget units and you get what you pay for. For low to medium price bracket systems, these will do fine but it is advised to spend more on a psu on higher systems and in general as they are one of the most crucial components in your pc.
