    An Antec 380w would be enough for around $40 but here is a higher watt PSU on sale.

    Thank you. Just hope that rebate ends tomorrow later in the day and not early, because im buying tomorrow
  3. The SEASONIC G is a better PSU.

    Better as in reliability? or just Watts? Because i think the 550W is just a waste of money since im probably not using more than 400
  5. Most give you 2 weeks after purchase. Long as your order is with in the time on your receipt.

    Still, if the rebate were to end at say 2am id be SoL. Because im probably only ordering after 3PM due to circumstances
  7. Better Platform and Gold Efficiency.

    Other is still a good value. But based on the GB Bronze.
  8. If you cant make the rebate time this one is good for your system.

  9. I would still take the Semi-Modular G.
  10. Great. Thanks for all the answers guys. Really appreciate it.
  11. Whomever recommended you the G , was right on it's a great PSU. Most SEASONICS are.

    It was actually another person answering a build list question I had. He recommended it over a EVGA 600W i think
