Hey there!

So yeah I will be buying a Geforce 9600GT soon (don't know what make yet) and I know the psu I have won't cut it, 305W. I have an Optiplex 745.....just need to know what kind of psu I can buy for pretty cheap that will handle it. I alotted all my money for the video card itself so I need to get something cheap....Thanks!

If memory serves, most Dell P/S units are proprietary. So, if that's still true and you use the same MoBo that came with it, then you'd have to go with Dell or a 2nd-source manufacturer for a sturdier power supply (which may or may not exist and would likely be pricey if it does)...

Another consideration is the ATI HD4670...it's made to work with OEM power supplies and pretty close to the performance of a 9600GT.

I agree with Skip. Both him & I have been hawking the Radeon HD 4670 as the best gaming card you can get without needing a PSU upgrade. It's the ideal choice for OEM systems with lower wattage PSUs.

What is proprietory?

Any way I can get a hold of one "proprietory"?

T-R-A means that you may not be able to use an "off the shelf" power supply. A proprietory psu could have different dimensions or be wired differently.

The Optiplex comes in 4 flavors...I assume you have the Mini Tower.

What's the exact model number or better yet, the Service Tag Number of your machine?

Apparently the HD4670 isn't an option that interests you?

The 9600GT isn't all that much better & will force a PSU upgrade, so you're gonna be looking at $125-150 vs about $60.

Well an ATI card was going to be my first choice, actually, but I will be switching to Ubuntu frequently and there is a lot less support for ATI chipsets versus Nvidia.....

Appears to be a dimension difference between the Dell psu and a standard psu...

5.9"x3.4"x5.5" vs 5.9"x3.4"x5.9" (WxHxD)

The Mini Tower you have appears to have a release mechanism at the back that might interfere with a deeper psu.

PC Power and Cooling makes psu's to replacae the Dell units.

35A on the +12v rail...

not cheap...

Linux drivers are available from ATI for the HD4670

I'll just bet there's a right and wrong procedure to install 'em depending on whatever flavor of Linux you're using too. Some distros might require installing in text mode...hell, I don't know. I have problems with lots of drivers in the various Linux flavors. This is worth a read though.

A couple comments

9600GT is gonna draw and additional 7-9 amps (~85-105 watts) of +12vdc power.

PC Power and Cooling builds outstanding psu's.

Good luck with whatever choice you make.

Well that is not too bad considering if I do go with the Hd6 card I should still be able to afford the video card. Thanks for the help!

Well, I will definitely take the suggestions and go ahead and buy the ATI card. It has a rebate offer and a free game of some sort on Newegg right now.

Sounds pretty good. Thanks for all the help, folks!
