Ac Power adapters vs ATX PSU

[Midghost 7]

Can anyone tell the difference and which is best and safe and reliable.

ATX PSU is a power supply unit inside a typical desktop PC. An AC power adapter, or AC/DC adapter, is a external power source--similar to a PSU--to power a device. They are similar in usage but, very different. A custom desktop uses an ATX PSU while a laptop using an AC adapter.

 

As far as your question, manufacturer-branded AC adapters for your product--i.e. a Dell laptop--are the obvious choice if you want safe and reliable. Universal chargers are okay but, some devices prefer their own charger, specifically Dells. If you want brands for power supplies, it's hard to say. I, personally, use a 750 Watt EVGA gold version and it suits me just fine. Researching the product you're interested in is always the best approach. For starters, cheaper is never better, especially when it comes to a part that allocates electricity in your PC.

this especially. Never buy a used PSU. The PSU is the scariest possible point of failure in your machine. If you have a bad PSU, you could end up frying everything connected to it (aka everything in your machine). 

 

You can use a site like pcpartpicker to get a rough estimate on how much wattage you need for your build. Take that and buy something at least 100W higher (if not more) to be safe and to have room to upgrade in the future.

there are many other good options but i wouldn't know your regional market to be more specific. 

 

550w is fine for most cases and can handle even the most powerful gpu and a good number of disks. 

not for sli obviously.

you might be fine with 450w depending on your parts, if you gonna have a $200-300 gpu then its fine too
