can i run xfx hd4870 1gb on fujitsu siemens m460 workstation's power supply???

its an branded power supply from fujitsu workstation m460 called NEWTON POWER LTD model= NPS-400AB B rev 05.

ac input 100-240v ~8A 50-60hz
main output +5v=26A max, +3.3v= 24A max, +12v1 =15A max(18A max 10sec), +12v2=15A max(18A max 10sec), -12v=0.5A max, +5vaux=2A max.
max continous output power is 410w.
max combined output power on =+3.3v &+5v is 190w.
max surge output power is 470w for 10 sec

that PSU had one 6 pin connector and i have one 4 pin to 6 pin connector in my gpu's box.....

so, that means i gonna have both of the 6 pin connector one is built in in the supply and one i gonna connect with 4 to 6 pin connector.....

so the above mentioned specs of the PSU is good for running hd 4870 or not??? plz let me know guyzz.... thanx in advance :)

That is a 400w PSU and fails to meet the minimum requirement for the HD4870 (min of 500w). See this link:

You can certainly try to use your existing PSU, but if you do, DO NOT OVERCLOCK the GPU. Doing so would put too much stress on an already minimal PSU.

I recommend you install a quality Seasonic or Corsair 500w (or so) PSU to meet your needs. The HD4870 is fairly demanding in terms of power and it will generate a fair amount of heat (which will also stress your PSU and system as a whole).

Good luck!

I think it will work just fine.

Lets do the math. Rail 1. 12volt x 15amp = 180watts
rail 2 12volt x 15amp = 180 watts

So we have 360watts of solid 12 volt power to use.

The 4870 has a max draw of 150 watts.
Im going to guess you have a core 2 at 66 watts, or a i5 at 77 watts, or an athlon at 95 watts. Add in 50 watts of 12 volt power of the board, fans, and stuff and you have a 150 watts, of cpu and board power.

Total it up and we have an ESTIMATED max draw of aroun 300. A good bit below the 360 that the PSU is good for.

Here we see a 4870 and a core 2 quad qx6850 pulling about 280 watts. That CPU is a monster with a max draw of 130 watts. Chances are your CPU will draw less.

In reality you complete computer will draw much less when in normal use, and only big numbers like 280 watts when gaming.

I think it will be fine.
Q9550 95 watts
HD4870 150 watts
Fans, hdd, board, around 50 watts. Your computer will have a similar draw as the one in the link around 280.
PSU should be good for around 360.

I would do it.

Just keep on eye on your system temperatures after installing the HD4870, particularly for the GPU. Over-stressing the PSU will generate more heat than normal and could lead to unstable power. Good airflow to keep the system cool will help mitigate the heat.
