psu's are very easy to fit just replace the wires as you unplug would be the easiest way for you, you will be needing at least a 500w
how about this

Is it definately a regular sized ATX psu slot? It might be micro-ATX (or worse still proprietary...)

9600GT draws 95W max so a true 400W PSU will certainly be adequate (look for something which gives over 28A combined on the 12V rail - many cheap PSU's lie completely about the power rating and are woefully underequipped on the 12V line where the power is needed!) Something like this 460W coolermaster would actually be a lot more appropriate than the 700W monster above, although if you can afford I'd spend a few more quid and look for a high-efficiency PSU (something 80plus certified)

As said easy to fit + don't skimp on a PSU. Go for a quality make.

Can you take a photo of the back & inside of the case? Should be obvious from that if its a regular ATX PSU...

Not related but I've just found out my 125Watt laptop only uses 35watt when its sat downloading stuff to an external USB drive. Thought it would be more.

BTW that's a regular PSU get a good one

Yeah, thats regular ATX and you've room behind it so your options are vast. That one puts out 15A on the 12V rail - the new card might consume upto around 9A more so anything rated above 25A or so on the 12V rail will be okay - that should be pretty much any reputable, branded PSU above 400W...

The one you're looking at on ebay would do, but personally I'd just get it retail from an online store like ebuyer, scan etc.

Probably not I'm afraid, OEM PC's generally don't have much room for maneuver when it comes to the PSU and that graphics card draws quite a lot more than the old one...

with a 9600 you should have at least a 600w

On what grounds? It draws 95W max, where are you getting your figures from?

The PSU in the case at the moment gives out 15A on the 12V rail - its safe to assume that a PSU that gives out over 26A on combined 12V rails will therefore power the system and the card. Maybe if it was a real cheapo '500W' PSU that actually only could supply 350W you would have problems, but a true-rated PSU wouldn't have to be anywhere near 600W.



Not quite, its one of the cheapo PSUs I'm refering to above. The ratings for it are:
Model 450U DC Output:
+3.3V - 20A
+5V - 30A
+12V1 - 10A
+12V2 - 13A {12V combined - 23A (276W)}

See how its only 23A combined on the 12V rail (and stupidly over-specified on the 5V/3.3V rail) - this is a common trend with cheap PSUs. You better buying one from a more reputable brand, but if you really want a cheap one get the '500W' model...

If you compare the above outputs to, for example, the Antec Earthwatts 430 (so supposedly 20W less...)
+3.3V - 20A
+5V - 20A
+12V1 - 17A
+12V2 - 16A {12V combined - 33A (396W)}

Have a look at the reputable list over at :

You will spend more on a good PSU, but it is worth it.
