Dell Studio Dell XPS 435 Power Supply

[watcherjcs]

Hello,

Where can a guy find a good 500+ power supply to fit this Dell XPS 435MT factory case?
I want to upgrade my video card (ATI 4850) because of overheating shutdowns.
I want to get a decent video card, but am concerned that the power supply will take a dump shortly after I upgrade the card.
I am looking to possibly install a Nvidia GTX 550-560, anybody have experience with these cards running in a XPS 435MT?

Being a minitower any std size PSU should fit http://www.newegg.com/Product/Product.aspx?Item=N82E16817371030
The std PSU is not enough for the cards in question.

Thanks for the great suggestion, yes I did check out the Antec 520 watt PSU.
It would easily do the job of powering a Nvidia GTX 550 ti.

Looking a little further into it I realized I could get the Antec 620 watt for a better price with rebates and promo code. =) And that would give me a little more room to work with on video cards that draw more power.

I talked to Dell about an upgrade to the ATI Radeon 4850,
they only offered ATI Radeon 4350 given my power supply size of 360 watts.
They gave me the power rating on this PSU by the "service tag number" which if you look at the label on the PSU it says 300 watt max output.

Due to the PC instability (hard crashes) I was dealing with, running the ATI Radeon 4850, I decided to change out the graphics card and PSU with the Nvidia GTX 550 ti.
and an Antec 620 watt power supply. I got a little bit stronger psu in
case this GTX 550 ti does not work out, I can easily move to a more powerful card.

I am currently running the new Nvidia GTX 550 ti on the factory 360 watt psu.
Although I would not recommend anybody try that.
(very odd, the label on the psu says 300 watt)
I know it sounds crazy, but I'm waiting on the new Antec 620 watt PSU to be delivered.

I was really glad to find more powerful power supplies for the Dell 435mt easy to get.
I am not running any games or graphics software (such as Adobe) at all, sooo.
Hopefully this PSU will hold together for a couple more days till the new PSU arrives.
fingers crossed

In researching power supplies, it seems confusing to determine by looking at the boxes in the store for specs, and matching the DC power output required by the graphics cards.

Example: 750 watt PSU, 4 x 12volt rail output 20amps each rail for SLI configurations,

a graphics card that requires DC output of 12volts and 30amps on 1 PCI-E connector.

Question: Is it possible to draw the required current for the card of 30amps given the 20amp restrictions of the power supply rails, or do you look for a PSU that has less rails and higher amp output, say 2 x 12volt rails at 40amp DC output each?

Thanks.

I am currently running the new Nvidia GTX 550 ti on the factory 360 watt PSU that came in the Dell 435mt new.

I wanted to add that I have not added any of the software that came with the
Nvidia GTX 550 ti other than the basic driver that came on disc.

I would go with somethign bigger than what you need power wise - youll never know when you want another card that takes more juice then youre in the same situation all over again .

Is the size of the graphics card an issue given the size of the case? We have the same system and I'm considering the same card, but worried about the fact the video card fan is only a 1/2" to 1" away from the bottom of the case.
