this is the only compatible unit I can find producing 400watts.....but it's quality is rather questionable....

Your Dell Studio 540S Slim uses a TFX form factor....and TFX compatible power supplies.

Here's a review on that unit: http://www.jonnyguru.com/modules.php...Story&reid=281

Bit of a mixed bag, it should be efficient enough for the OP's needs. Build quality seems to be pretty bad, that said there doesn't seem to be any competition in the area. The reviewer mentions Seasonic selling 350w TFX units, but I can't find any.

I thought you wanted a 400w unit, that one is only 250W.

If you want to power a basic system, yes. If you want to power a system with a dedicated graphics card, no.

That's actually a stock unit for the OP's model on Amazon...

exactly, so....not an upgrade.

well... the 7750 will draw around 45w under load all by itself, which is small enough to not require an external power connector:

http://www.guru3d.com/article/amd-ra...-7770-review/7

However, you still only have a 120w PSU, a lot of which will be taken up by the rest of the system. You can probably shoehorn in the 7750, but just know that AMD recommends a 400w PSU for the 7700 series.

guys i just spoke to dell and they said that my psu wasnt 120 but 250W
which now changes the question
which card will be the best for it?
or should i just upgrade the psu which will cost me to much money?
i dont know what to do
please help

The wattage is of little concern.....so long as enough is available. However, Dell PSU's are generally overrated and produce the minimum possible amperage. While being rated for 250watts may provide enough wattage to run a system + HD7750, it's extremely unlikely that it produces the amperage necessary to do so.

Can 7750 run a 250w psu?
psu is 250w with 12v-16 amps
i had 4650 dat consumed about 55W , the same thing that the 7750 consumes
so can it do it?

I Say yes^Hd7750...Give it a Shot...Please check back and let Us Know how it works....Thanks......

[automaticman]

the 7750 is roughly double the performance of the 6570 for just a few more watts of power.

will do
hopefully

[beyonder]

i feel really silly now
ihave the slim computer
theres no low profile for that card yet
sigh
6570 it is then

[automaticman]

one last option is to just get yourself a new case. While this will cost a bit more (not too much depending on teh case) it has several big advantages:

1) Now you can buy any ATX (standard size) power supply you want and get more power/better quality for less money.

2) Now you can also fit any video card you want (although case selection will play a big role here, but most cases will fit all of the popular cards - certainly everything we've mentioned here)

3) Now that you have a case and power supply you own the two components most likely to be kept when you upgrade your computer and won't need to be bought again. Pick up a new motherboard/CPU/RAM combo, drop them into your case and you've pretty much got a whole new computer - and one without all of the restrictions you get with an HP (or any other OEM) PC.
