Is a 550W 80+ Gold PSU Enough?

Looks to me like their is a $100.00 sticker put on a $10.00 power supply.
A quality outlet to computer cable cost $10.00.

Bryan I think your underwear are safe from destruction. Try a ham and cheese.

You have got a ton of information from all the post. I will keep it simple.

Do not, I say again, DO NOT put a junk $10.00 power supply even close to a computer let alone install it into your computer. A junk power supply can cost you your entire computer or at best your computer just won't work.

Yep well Rain08 that is what you get with those bundled case buys - there are some that come with better known brands ie Antec Coolermaster etc but even then the PSU is still at the economy end of their ranges.
Always best to get a decent case and fit the better PSU because as Scott Mueller states the PSU is more often the problem than people give credit to and why when I start looking at problems I always begin with testing the PSU because if you think about it without it performing correctly - nothing is going to work properly.
Don't know if I posted it earlier but this is a good article

I changed my mind on my GPU, I'm currently thinking of getting the Gigabyte Xtreme Gaming GTX 950. AFAIK, it needs an 8-pin PCI-E power cable. Will the 6+2 work on the G-550? I don't have experience yet on GPU's needing PCI-E power cables.

A 6+2 connector is made to work with 8 pin PCIe power sockets, so no worries there.

If you like Seasonic and that`s what you can get, that`s fine, but I would always get something above what you think you need.

I would go 650 to 750, whatever Seasonic makes, and always stick to at least Gold certification.

The thing is, with that 550 watt Seasonic, it leaves you very little for future expansion, and you`d end up buying another PSU anyway, just something to think about.

Whatever you definetly decide on, post us the link so we can advise again.

Looks like there's not many choices in that price range :/

Not sure what hard core gaming is ?
You're either playing new games or old games
New games aren't getting easier on hardware :)

That's a good PSU. Above link is a review. That's a pretty good price for it too, considering the exchange rate.
