Lousy Dell PSU...

I have an Optiplex GX620 SFF tower. I don't think I can replace the PSU, so what's the best graphics card I can use with that setup? Currently, I've got a P4 3.4, 2GB of RAM, and a Radeon x600 SE.

Keeping my first post short and sweet. Sorry 'bout that.

According to Dell, the mini tower has a 305Watt PSU...Which is the bad news. The good news is that Dell PSUs are actually quite good, particularly on the importaint +12v rail.
The best you can put in without messing around with the PSU is the HD4670, it only draws 48Watts under load so needs no external connector, taking all its power from the PCI-E slot.
And it`s no slouch at lower resoloutions for games either!

You have 22amps @ 305w continious power, not so lousy for what you have.

February 27, 2009 8:06:41 PM

I meant lousy more in the sense of not being able to put a bigger one in. It may be getting up in years, but I still love this little thing.

People have run 8800GT's with that same psu.
February 27, 2009 8:17:01 PM

If you are limited to low profile that makes it a bit tougher. The nvidia 9500gt is a decent card without a power connector. Newegg has a couple low profile versions.
February 27, 2009 8:18:50 PM

since your cpu will be holding you back quite a bit, i'd suggest the sparkle 9600gt. anything more will just be a waste
February 27, 2009 8:24:24 PM

The 9600 GT is tempting. Maybe I could finally play Fallout 3...

Thanks everyone!

The GX620 "SFF" uses a 275 watt 17 amp psu, the mini tower uses the 305w.
February 27, 2009 8:29:49 PM

I can never keep those acronyms straight! I have the mini tower then. thanks for the clarification!

If you have the mini tower you can upgrade the psu with almost any standard unit, and you don't need a low profile video card.

+1 for the 4670. you should be able to run it without problems.

That's the desktop model, no psu upgrade and low profile video cards
February 27, 2009 9:20:39 PM

Ah gotcha. So am I still good for a Radeon HD 4670 or GeForce 9600 GT?

Should be able to run the 4670 with no problem, not so sure about the 9600gt though.
February 28, 2009 12:36:27 AM

9600gt requires a 6 pin PCI-Express Power connector so I dont think you can run it :: looking at one right now to make sure::


also dont think it matters but there is no such thing as a low profile 4870 even thought newegg says they have one lmao

9600GT will be fine. That PSU has >20A on the 12V, which easily will run up to around a 9800GT/4830.
February 28, 2009 1:12:13 AM

most 9600gt come with 6pin pcie power adapters. so either a 4670 for lower power or 9600 for better performance...

you should get one of these for your graphic card

it can power a gtx 260 and i heard it can even power a gtx 280 which is good

He would then have to remove his optical drive, or mount it outside and cut a hole in the case in order to wire it up.
February 28, 2009 1:53:05 AM

I don't think I want to go to that extreme a level. I'm just looking for a better card than what's in there now. Truth be told, the computer will be passed down to my preschool age niece in a year or so.

According to SLI zone the 300w version of that product (FSP x3) can handle a gtx295 :p .

The 450w could handle two gtx 260's

What is it that make's you sure ?

February 28, 2009 12:04:46 PM

a 300w can power a 295 but a 450w can power sli'd 260 (which basically is a 285 on one card.) that makes no sense and screams bs.

Hello TINKY, sorry, did n`t spot the SFF part of your spec:( 
I can`t see any useful low profile cards for gaming apart from this;

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

It`ll draw a maximum of 60W at full load (5A) while the 4670 draws 48W (4A) so I`d say you r`e good to go with the 275W PSU.

How is this BS ?
The GTX295 uses about 214 watts of power, shouldn't be a problem for a 300 watt dedicated graphics psu.
The GTX 260 uses 156 watts or less depending on the model, when run in SLI the power consumption does not double but for arguements sake let's say it does.
2 x 156 = 312 , how would that be a problem for a 450 watt dedicated graphics power unit ?
February 28, 2009 2:50:47 PM

thats probably the old 65nm 260s and phased out already. the 55nm should have a lower draw

The 55nm's do have a lower draw, which is why I stated that consumption was dependent upon the model and used the highest power draw as an example.
Xbit labs put the GTX 260 55nm at 104 watts, two of them would run on a 300 watt graphics power supply.

Why is this BS? Max load with SLI 260's will certainly not pass the 450w break point. Full 3d load on a single 260 is 191.2(according to http://www.tomshardware.com/reviews/geforce-radeon-powe...)

I know the 450 wattage seems low but you have to remember that this is a dedicated GFX card supply.

One last question and I'll be done (I think): Which card do you recommend that won't be overkill coupled with my P4 3.4 and 2 GB of RAM? I keep thinking that a card like a 9600 will be bottlenecked too much with my other components.

Again, thanks for all your advice!

Does the PCIEx16 in your motherboard has max power limitation?
Mine is optiplex 320 and it limits my PCIE to be <25W.
I don't know if it will work with some graphic card which draws current only from the PCIEx16 only (i.e. HD4670.)
March 18, 2009 5:00:38 PM

How would I check that?
