So, I have a budget gaming system that has been running for about six months with an Antec Earthwatts 380w PSU. Here are the specs:

-Pentium Dual-Core e5200
-2GB Memory
-4850
-1 SATA HD
-1 DVD burner
-Earthwatts 380w

There are 2 small upgrades I want to make. I used an online PSU calculator and it looks like the PSU can support what I want to do, but I thought I should look for advice. The calculator said the system with 4890 would only need about 260w.

1) Overclock e5200 to 3.0Ghz and add 2 GB memory

2) Add 4890

Will the Earthwatts 380w be sufficient? Keep in mind it has 27A for the dual 12v rails.

the HD4890 uses about 50 watts more power than the GTX260, so you'd be up at 340-350 watts. I sure wouldn't recommend using your 380w PSU with the build.


Excellent link. Thanks for responding.

My question now: will the Earthwatts 380w be enough for overclocking the CPU to 3.0 Ghz for a little above?

I plan on waiting for the Radeon 5000 series to come out anyways, so I'll just buy a better PSU then, and either get a cheaper 4890 or a 5850 if the price is right.

It should be alright. Unless it is more than 2 years old, then I'm really not sure.

I'd have no problems using it with the overclocked E5200 and a HD4850.

Awesome. Thanks for all the help!

I'll upgrade my PSU when I upgrade my GPU.
