Antec TruePower 550W PSU?

I'm running an Antec TruePower 550W PSU which is drawing at peak loads 280Watts @ 3.03 Amps. I'm thinking of adding a 2nd water cooler (for chipset and graphics card) that will draw power from my existing Antec 550W.

What are the safe load numbers I can take my PSU upto before I need to start thinking about upgrading (to something like a Silverstone 600 Watt PSU)?

    Ok thats a TrueControl, and its and older model(maybe 1 year older than yours). They say stable operation at 495W
    I dont expect your water cooler to draw more than the 200+ you have left...I guess you will check the peak power consumption before buying your 2nd water cooler!

    Anyhow I'm getting<A HREF="" target="_new">This case</A>
    Its a good 30-50$ cheaper than the 1088AMG and it comes with a 500SP. Reason of the upgrade is I made a deal and ill receive a 6800Ultra in exchange of some work. Im sure my TP380 wont handle the extra power!

  2. thank you for the link, very good article -- I'll stay with my Antec 550 TruePower.

    Nice case choice and I like the option to add power lines as need to the PSU.

    Have you looked at some of these cases?


    I've built a couple of systems using these cases and I was VERY impressed with them, and very lightweight too :) They're about $100 less if you buy from other sources.

    I did have to modify the first case to make a Silverstone 600 Watt PSU fit -- but it was a simple task and clean. I'm also very impressed with Silverstone 600 Watt PSU, be warned it is long and HEAVY!

  3. Thanks for the link but I already have the case =)
    I like the antec brand never had any suprise.
    The case is really roomy and well designed, modular PSu is cool, a little easier to do cable management hehe.
    Also the "Thermally advantaged chasis" like intel likes to call it worked pretty well! That and the fact that the case is bigger and has a 120mm fan helped reduced the temp of almost 5c!
    My cpu is idle at 25c and havent try really tortured the system yet but around 35-38 under full load pretty impressive(NorthWood power!).
    And my new GF6800U is running at 53c(in heavy 3games havenet benched yet) wich I think is really acceptable! Im still burning in the card cant wait to OC some and unleash some more poer =)
