Will my build support an HD 6670?

Hi friends, I asked some people about this and all of them gave me different answers. So please, do help me out of this! Look, I wanna buy a new graphic card , an HD 6670(preferably a Sapphire HD 6670 100326L). I have a PSU that came with the cabinet bundled. I do not have much power hungry parts, look for yourself!

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. Your psu might even be an overkill for an athlon 2 x2 245 with a 6670, so no worries :)
    According to newegg your system should consume around 293 watt (with 6670).

    The 6670 should work ok.

    The new 7750 is faster than the 6670 but uses about the same amount of power.

    It's a old power supply. Most modern power supplies have most of the power on the 12 volt rail, this one has a 29 amp 5 volt rail and a small 18 amp 12volt rail.

    Before the pentum4 and athlonxp used lots of 5 volt power to run.

    am3 cpus use 12 volt power to run, so that 65 watt cpu is running off the 18 amp rail.

    18 times 12 = 216 watts. Basically you have a 250 watt power supply.

    antec and corsair rate their power supplies at 100% 24/7 load, but most oem's and cheap brands have a 80% duty cycle. meaning it can run peak at 216 watts but 24/7 at 80% of that.

    =172 watts. It leaves you with 72 watts to run the card with.

    The 6670 or 7750 is still cutting it close, really close.

    You should have a look inside for leaking and bulged capacitors, since that will cause ripple and can damage your board and memory.
  3. It seems to be fine, but do not overclock.

    The 6670 doesn't require a external power connector so it limits power at about 75w, which the 6670 doesn't usually run at.

    AMD recommends 400w but it'll run fine with even a quality 300w.

    I prefer the Antec because it has just the right amount of power, not to much- but not running 100%
  5. So you all say I should go for it? Coz I am not gonna overclock it!
  6. As long as you have a pciex16 slot you are gtg have fun
  7. I run almost identical specs-
    GA-MA785GM-US2H
    3.5 gb ram
    AMD Athlon II X2 240
    450 watt psu
    HD 6670 gpu

    Runs Crysis on "very high" with minimal lag

    By the way, go to tigerdirect and get the Asus card. it's almost the same card as the sapphire but for $75
