550 watt psu with asus GTX 470. is there any risk?

Hello,
i bought a new psu thermaltake tr2 rx 550 watt link (http://www.thermaltake.com/product_info.aspx?PARENT_CID=C_00001555&id=C_00001556&name=TR2 RX 550W&ov=n&ovid=). gpu requires minimum 550 watt and 38 amps on 12v rails. Am i safe?

  1. the TR2 550w is on the low-end, and it has a combined 33A on both rails which is less than the recommended 38A needed for a GTX 470.
  2. huh? there is a new TR2 550w?
  3. thanx for the replies. what GPU is best for this PSU thermaltake TR2 RX 550 watt.
    should i go for ati radeon 5870? or NVIDIA GTX 460? .. theres no way to chng my psu.. i just want a stable and long lasting system..
    my current system is:
    PSU : thermaltake tr2 rx 550 watt
    CPU : intel core 2 duo E6420 3.00ghz(OC)
    RAM : 3gb DDR2 800 (945mhz oc)
    MoBo : gigabyte G31 S2L
    HDD : wd cavier black 1tb and hitachi 250gb
    GPU : help me to decide :)
  4. The HD 5870 would be quite a lot faster than the GTX 460, although it is nearly twice as expensive.

    I suggest you go for the HD 5870 if you can afford it/fit it into your case as the TR2 550W should deliver enough power.

    Also a CPU upgrade from a Core 2 Duo to a Core 2 Quad would be good as well if it's within budget later on.

    +12v1 19A
    +12v2 19A
    total 38A(456watt) continuous power ... is that safe to run GTX 470..

    to be honest, pairing up a 470/5870 with your current hardware is going to cause a nice bottleneck. If your budget is around 400.00$ I would do some research and upgrade the mobo/CPU/GPU. This way you will have a more balanced system with better upgrade path options. If this is not an option then I guess I would opt for the 5870.
