Studio XPS 435MT and the Dell ATI Radeon 4850

 Thinking of changing out my 4850 for a Radeon 5770 to up performance a bit and for DX11, but mainly to deal with the heat from the 4850. From all the reviews it seems the 5770 not only uses less power but generates quite a bit less heat. Anyone see any issues?

I don't know about the 4850, but I swapped out my 4670 with a 5770 and it is DEFINITELY quieter and generates much less heat.

 Thanks Domer! This is in a 435MT, yeah? Good news. :)

Hi

When installing your hd 5870 did you have any issues with space? I want to install the sapphire hd 5850 toxic and wondering if it will fit due to it being a similar size?

Also assuming you have no extra cooling system other than the original 435mt setup, have you had any problems with overheating or air circulation?

Also a small matter of interest to me concerning power usage

I currently have a dell studio xps 435mt using a 350W power supply. If I upgrade it to a 750W power supply but keep the rest of the system the same, will it use the same amount of electricity because it only uses what it needs? or will it use more because of the greater wattage?

I dont really know about such things

Much appreciated

On the space issue, I did have to remove my second hard drive, as the Radeon 5870 extends into the 2nd hard drive bay space.  It was also a little difficult to connect the two power cables, because they are underneath the metal frame (that forms the side of the drive bay chambers).  But it does fit.  Also, be very careful about the cables that connect to the motherboard on the very bottom of the chassis - when you plug in the video card, they tend to get in the way and may get stressed or unplugged.  One of them is the interface to the USB module on the front panel.

I made no changes to the tower other than to install the new supply.  It runs much cooler and quieter.

Regarding power consumption, using a larger power supply generally won't increase your overall power consumption because as you say, it will only use as much as it needs.  But no supply is 100% efficient and there is always some amount of power that gets wasted in the conversion process.  A larger supply may have a little more "overhead" consumption, but if you get a high efficiency supply, this will be negligible (and maybe even better than the stock Dell supply).

I'm installing an Antec "Truepower New" 23652 TP-650 power supply in my Studio XPS 435MT to go with an Asus EAH 5850 video card. Can I use the 2 6-pin plugs that are built into the cable or MUST I use an additional modular cable for the second plug?

Hi

Installing an antec truepower new tp-750 psu into my 435mt and was wondering which graphics card to upgrade to. Was going to go with the 5850 toxic, changed my mind and was just about to go for the 5870, and now Nvidia have finally released their gtx 480/470. From what I have seen the 480 KILLS the 5870 so was going to ge tone when they come into stock.

My question to anyone knowledgable about such things is does the 435mt support these new Nvidia cards? I have no experience with Nvidia so would like your opinions on whether this card would be suitable?

thanks

Chris,

I bot my Dell XPS 435T i7 920 (now the 9000) back in Sept/Oct of 2009 and it had the Radeon 4850 with 512mb with 475PSU.

Can my machine handle the newer Radeon 5770 or 5870 cards that Dell current sells with the a similarly equipment XPS 9000 with the Dell stock 475w PSU?

Also, can I upgrade the processor as well? If so, do I also need to upgrade the fansink?

Thank you!

I have a Studio XPS 435MT that I added an Antec Truepower 23652 TP-650 power supply & am using an Asus EAH 5850 video card. I was able to use the 6 6-pin plugs supplied with the PSU (no additional cables) so he should be able to use a 5770 card with no problem (the 5850 uses more power than the 5770)..

 I've got a 435MT with stock PS and recently installed a 5770 (XFX HD-577A-ZNDC) and it's been fine. Performance isn't a big leap but the card and the whole case (even the CPU as a result) run much cooler than with the stock 4850 which was my reason for the switch.  Everything I'd read showed lower power consumption than the 4850 so I thought it worth a shot.

Turn the PSU over. The fan goes on the bottom, facing the heat sink.

Hi again

One more thing, there looks to be a lot of cabling for such a small case, how did u keep good airflow?

Thanks

 This'll seem like a silly question, but what do you guys do about the fan I see on the top of these power supplies?
