Will my Power Supply Unit support an HD 6670?

Hi friends, I am first at Tom's. Please do guide me through the problem!

First I will give you the info-

My system specs---
# A GA-M61PME-S2P motherboard
# 2 GB kingston DDR2 RAM( will upgrade to 4 GB)
# An AMD Athlon 2 X2 245 CPU
# An Intex 450 W PSU (bundled)
# A PCI-E x16 slot
# LG Monitor with max 1400 X 900 resolution.

More info about my PSU....
This is exctly what is written on my PSU..

Smart IT-2045S+
450 Watt, 20+4 Pin , 1 SATA , 3HDD , 1 FDD, 1 FAN.
AC INPUT: 220V 50Hz 5A
DC OUTPUT: +3.3V: 30 A +5V: 29A+12V: 18 A -12V:0.5 A +5VSB:2A
ATX 2.03

Now the question is if my PSU will handle an hd 6670 or not. If it will, which brand should I buy( Sapphire, XFX etc.). Also tell me if the card will be compatible for my PC or not!

I don't want to upgrade my PSU so if my PSU will not handle 6670, please suggest me another card!

Any help will be greatly appreciated! I have been using an 8400GS which has a TDP of 45 W and the HD 6670 has a maximum TDP of 63W. So, I think that it won't make such a difference!

  1. AMD specifies a minimum of 400watt power supply, so technically yes, if your PSU can deliver it's rated power you'll be fine. Usually the bigger concern is a cards demand for amps on the 12v rail, but as the 6670 has no requirement for a separate PCIe power connector, that's not really going to be an issue for you, as the most you can draw from a PCIe x16 slot is 25 amps.

    I say technically as I never recommend bargain or budget PSU brands. If you've not a had a problem than good, but the quickest way to kill a PC is to use a dubious power supply.

    Oh and for brands of 6670 Sapphire and XFX have always been safe AMD brands to go with.
  2. AMutedScream is right, but i would suggest to buy same power 450W PSU like..

  3. Yes, I totally agree with you...
    But can you tell me how much amps I am having on the 12V rail??And also, the PSU I am having now is a generic one...So.????
  4. Does that PSU have the 6-pin cable for video cards? If not, it's a sign it won't be able to take any decent video card.
  5. The 6670 doesn't need a 6 pin cable, your psu is enough for the 6670 but if its a generic one, it might not last long.
  6. You have 348w on the 12v rail so I would bet the 6670 would be able to handle that. the 6870 use's a 168w on full load. I would say even if your PSU is a bad one you will still be able to run the 6670
  7. So, you all say that I should go for it....?
  8. I will once agian give a more detailed info so as to make it easier for ya all....

    Can you tell me how much amperes does my PSU render in the 12V rail!!!
  9. your psu give 216w at 12v rail
    a athkon 2 x2 250 needs 95w and 6670 needs upto 70w , equals 165w and thus you can easily use that 6670 without any problem,
    your cpu and 6670 needs around 15A rating on 12v rail

    When you first posted your PSU Info you left out the 18 A and now I see you put it in. Your total on the 12v rail is 216w. Your 6670 on load uses 68w And What ever your CPU uses which I know is around 90 to a 100w on load.

    Your 450w PSU is peak power so at peak power it will be 216w You throw in the 168w it leaves you 48w to spare. I wouldn't try OC'ing of anytype. Yes you are good to go with what you have.
  11. i am guessing thats the psu that came with your pc case. if so, best to upgrade it if u can afford it. try a corsair

    or the coolmaster from new egg, those psu that come with the case was not made to handle load, it was made cheaply to pass the standards. [ a simple weight test would suffice to prove this] hope this helps
