How do you know how much wattage you need?

post #1 of 8
Thread Starter 
Tried googling for this but can't find anything, for Christmas my family put together for a bunch of parts for my dad to build a new computer but we didn't get a power supply. We still haven't gotten one and with all these sales Newegg keeps having and that we got to check that the parts are working obviously soon, I'm just wondering how much power it should need.

It's going to have a Phenom 2 1055, 4 gb of corsair DDR3 RAM, a few SATA hard drives, DVD burner, graphics card eventually but for now just going to use the onboard unless it's really horrible, several case fans, external hard drives(it's work computer and he needs lots of storage) etc, typical stuff, just wondering if a 500W would do it because I saw one on Newegg and it seems about the right price. Thermaltake is good right?

500W is more than enough.

I'm personally a big fan of corsair power supplies. If price is an issue i would get this one
http://www.newegg.com/Product/Produc...82E16817139019

$45 after MIR for a 600W (the 500W is only $5 cheaper before MIR and is $5 more expensive after MIR)

It is more wattage than you need but that just means you have room to grow and the PSU isn't working as hard.

those builder series arent good from what i hear

to make this easy i would say to grab anything you see in our PSU FAQ between 400-600w.

Thermaltake is a negative.
http://www.newegg.com/Product/Produc...82E16817371029 will easily power your system and any GPU up to a GTX 460 or Radeon 6950.
http://www.newegg.com/Product/Produc...82E16817371030 would be fine for pretty much anything.

I'm running a 550W Antec Basiq right now, and it's running my setup just fine. Won't be overclocking until I get my CP-850 in, though. After my experience with this build, I'll be going to Antec from now on. The one I bought for my dad a while back is going strong, too. Basically, just get yourself a reliable one, from a good brand. I recommend Antec.

Thermaltake is good if you get one of the CWT Toughpowers.

The first one linked for $35 after MIR shipped is perfect for your needs.

Should support a very nice midrange GPU. If your thinking dual midrange GPU's or a single top of the line GPU then the second one linked will definitely do the job.
