Question about my 250w PSU.

Recommended Posts

Posted · Original PosterOP

Hello, I plan on upgrading my PC but im worried about my power supply. Here are my specs

  • Computer- Optiplex 390 DT
  • CPU- i3-2120 @ 3.30 GHz
  • RAM - 4GB DDR3 

I plan on upgrading to 8GB of RAM and an i5-2400 with either an AMD Radeon HD6450 or something equal.

 

Now if i keep my i3 processor and just upgrade my RAM and get a graphics card would the 250w PSU be good enough? Or should i just get a new PSU and upgrade the RAM and get the graphics card?

At least 400w to avoid any future issues

I would probably recommend upgrading the PSU.  With all the upgrades you are interested in, you will approach 250 Watts, and you should always leave some extra power headroom as well.

Upgrade the power supply so that you'll have a 6 pin PCI-E connector so that you can get a "real" graphics card. 

 

EDIT : Optiplex DT means you'll have a difficult time upgrading the power supply unless you're willing to go all ghetto and just place an upgraded power supply outside of the tower and leave the side pannel off.
