Rosewill universal power adapter for Studio 1558?

Anyone purchased this one?
Rosewill RNA-U100PRO from Newegg is only $40 right now.

I have the Dell Studio 1558 i5 setup.
Thanks!

 

there are a few things you should be looking At when purchasing an aftermarket psu
1) voltage--- can or is the new psu the same as your old?
2) amperage, the new psu *must* be ratted as high or higher than your old. do not assume that 100w is *enough*. the amperage ratting is right next to the voltage ratting and is measured in amps, not watts.
3) polarity, although usually if it fits it works, sometimes the plugs positive and negative side may not be the same as your laptops. A multimeter is required to check for this.
then you just have to consider that you get what you pay for. there are good brands and not so good brands. when I get back to my computer I think I still have my *naughty and nice* brand list from another forum.

 

I wouldn't recommend aftermarket power adapters, as a OEM Dell adapters can be found on Ebay for less than $40. Aftermarket adapters are usually of lower quality and could cause issues that will void your warranty.

 

using an aftermarket power supply will not void you warranty...in-fact I think there are laws that protect against that.

 

I doubt it, a poor power supply can fry the motherboard, therefore voiding your warranty. The BIOS might also not recognize it and reject it in POST as well.

 

the only way you're going to fry it is if you don't use the correct voltage or polarity plug. Even then You'd have to go out of your way to find a PSU that isn't FCC and UL listed, and certified in half a dozen specifications these days. after the voltage, the worst case scenario is amperage drops which might lead to premature shut-downs, but that's about it. Laptop PSU's are built to a much higher quality than Desktop PSU's just because of their nature and design.
