PSU Confusion

[MonkMan]

Hey there people,

 

I've been wanting to upgrade my graphics card for a while now, but i know that in order to do so i will first have to upgrade my power supply. But how do i go about choosing one? Does it have to have the same dimensions? :confused:

 

I currently have a GTX 460 and would like to upgrade to this: http://www.amazon.co.uk/EVGA-GeForce-Graphics-3072MB-Mini-HDMI/dp/tech-data/B0052HJFWK/ref=de_a_smtd

 

According to the Nvidia website i need a minimum of 600W

 

For example would this PSU work with my PC?: http://www.scan.co.uk/products/850w-psu-corsair-enthusiast-series-9020004-modular-85-eff-80-plus-bronze-sli-crossfire-eps-12v-quiet

 

 

Current PSU Spec:

• Form Factor: internal ATX
  
• Total wattage: 460W
  
• Nominal input voltage range:
  
  • 100-127V/3A (50-60Hz)
    
  • 200-240V/2A (50-60Hz)
    

  [*]Dimensions: 150mm x 140mm x 86mm (5.9 x 5.5 x 3.4 inches)

Any Additional Spec Details are here: http://h10025.www1.hp.com/ewfrf/wc/document?docname=c02681931&tmp_task=prodinfoCategory&cc=uk&dlc=en&lang=en&lc=en&product=5059357#N1399

 

Any Advise would be much appreciated,

 

Thanks guys,

Hi and welcome to ExTS

 

150mm x 140mm x 86mm - dimensions of your present PSU

150 x 86 x 160 (WxHxD) - dimensions of the new one.

 

If your present PSU is 140 mm deep ( i.e. goes into the case 140 mm ) then the new one could fit.

It is 20 mm deeper.

If you have space behind your present PSU then the new one should be OK.

 

I found this review on your card:

I can't see anywhere that refers to it as a "dual slot" - in other words .......a wide card.

This does look wide and your tower is a "midi" which may restrict space.

Just make sure that there is enough room around the PCIe x 16 slot for the card width.
