480W Power Supply enough for Nvidia GeForce GTS 450?


I have been wanting to upgrade to an Nvidia GeForce GTS 450. I'm getting bored of running Battlefield Bad Company 2 on low settings with my XFX ATi Radeon HD 4670. I wanted to know if my PSU is good enough for it. According to tigerdirect.com, it says that the minimum PSU requirement is 400W. I just want to make sure that I'm not cutting it too close or anything. Here are my computer specs:

Windows 7 Home Premium (64-Bit)
AMD Athlon II X4 620 @ 2.6GHz (not overclocked)
4GB DDR2 memory (2 sticks @ 2GB per stick)
XFX ATi Radeon HD 4670 (not overclocked)
480W Black Steel PSU

If this helps, these are the numbers on the 2 rows of my PSU:

Row 1: |+3.3V| |+5V| |+12V| |-12V| |+5Vsb| |Total|
Row 2: |28A| |34A| |18A| |0.8A| |2A| |480W|

This is the card I want to buy: http://www.tigerdirect.com/applications/searchtools/item-Details.asp?EdpNo=6680906&sku=E145-0452&SRCCODE=WEM2413C&cm_mmc=email-_-Main-_-WEM2413-_-tigeremail

I was hoping to buy the card this weekend, so any help would be great ASAP!

Thanks -- gotsupra1337

  1. It needs 22 amps on the +12volt rail you have 18
  2. The GTS450 uses 20W more than the HD5770, no a bigger no.
  3. Alright guys, thanks for the reply's! I probably buy a new PSU then.
  4. get a high quality unit from corsair, nzxt, seasonic, antec, etc. do not buy a cheap psu, like huntkey, raidmax, okia, coolmax, powmax, basically you get the point :)
  5. Better get a HD5770 or even better wait for a few weeks for the new ATI 6 series to hit the stores. The 450 is a new arrival, the price is not set yet and definitely it will be cheaper soon. The 5770 is getting cheaper by the day.

    If you want to upgrade now here's a sweet deal:


    Price After Mail-In Rebate(s): $144.98
  6. yeah, really, get a 5770 - faster/cheaper....unless you plan to SLI down the track.
  7. I know this is old thread but since 450 card drops in price recently it's good to consider other choices like this: http://www.newegg.com/Product/Product.aspx?Item=N82E16817139026&nm_mc=KNC-GoogleAdwords&cm_mmc=KNC-GoogleAdwords-_-pla-_-NA-_-NA

    BTW no power supply should be bought based on paper spec; solid manufactures are indeed the only way to go.
  8. ...although that particular model maybe not a good example of Corsair's quality which I still trust more than a bargain brand.
