Really cheap generic PSUs won't be able to handle the wattage that they're rated at, and normally cannot deliver much amperage on the 12 V rail.

Also the voltage stability is often poor and sometimes out of ATX specifications. If overloaded (which applys for below there rated power as meow said) some lack over current protection and will thus smoke up instead of just shutting off. They often have a much shorter life than branded PSUs also and can more likely take the whole system with it.

Always buy a good PSU, even if it means sacrificing some performance. Hope that helps.

There are good PSUs.
There are average PSUs.
There are bad PSUs.
And below that there are Coolmax PSUs. (and a few other brands, to be fair).

You may not have any problems though, especially if you're PC isn't drawing more than 300W DC.

If you list all your parts we can make an educated guess for you.
Or you can try one of the online PSU calculator like this one.
It's going to calculate a recommend SIZE of PSU - not it's actual power draw. So subtract about 40% and you should be in the ballpark.

Can you list the specific model? Coolmax has quite a few different models.

NewEgg is showing 4 models of Coolmax PSUs ATM. Including a $55 model with a $20 rebate.
Did you have any trouble getting a rebate from Coolmax?

That Coolmax V-600 is actually a 581.5W PSU.
Not a lot of customer reviews @ NewEgg but it's considerably lower than you like to see the ratings.


The good news is that your system is using less than 250watts DC power, probably closer to 200watts under load.
The PSU calculator recommended a 292watt minimum reqd PSU and a recommended 342watt PSU.
