New System - Older PSU - Enough Juice?

For gaming under full load, I think my current Antec 550W PSU might be pushing the limits on this config. Just wanted to get other opinions though...

CPU: Intel Core 2 Extreme QX6850
RAM: 4GB of DDR2 1066
Video Card: Radeon HD 4850
Motherboard: GIGABYTE GA-EP35-DS3L LGA 775
Drives - 2 Hard Drives and a DVD Burner

Misc. Crap - iPod dock, GPS dock, Cell charger, Wireless mouse, etc...

  1. Most likely. They degrade over time, especially older ones. How old is it?

    A newer Antec 550W looks like it would work on paper. They list like 60A total on three 12V rails... Which should equal more than 550W and so something smells.

    If it is the new Antec I would suspect it based on that. Looks more like total amps for all three rails is really 25. 4850 needs... 28? not sure.

    So anyway while some 550s might power that rig, best to choose very carefully.

    PC Power and cooling has a nice 610W on sale I think.

    Corsair has the 750TX also on sale and a real good PSU.

    Thanks for the response. Time wise, the one I've got is under a year old.

    Specifically, it's the Neo HE 550W

    If you don't overclock it should hold perfectly. Not much headroom, but not above specs. If you ever go another PSU, Go Corsair TX750. Excelent PSU in its price point.

    Your Qx6850 uses about 2 amps more power than a Q6600
    Your HD4850 uses about 2 amps less power than a GTX260
    Look for posts by invisik, as a test, he's running dual GTX 260's and an overclocked Q6600 on a 500 watt Antec, there is no way you're pushing the limits of your year old Antec HE550 psu.
  5. You should have much more than enough. Here are the system requirements for the 4850:

    The power requirements for your other parts are fairly typical.
  6. Thank you all for your replies. I'll hold off on a new PSU unless I run into problems. It's good to hear that the odds are I'll be saving some cash. :) :bounce:
