Dell Optiplex GX280 PSU

Hi,

My Dell Optiplex GX280 (Small Mini-tower) has got 250Watt psu and i am going to install Nividia GS8400 (512MB) in that machine. I can see 400, 450Watt PSU available online but these PSU have got either two holders or one holder + on/off switch which would not fit into that machine I believe. (http://www.dell.com/html/us/products/optiplex/GX280_3d_model.html)

Can anyone recommend some workaround or some place to buy Dell compatible PSU at GOOD price?
Thanks

Get a new PC, The rest of the system will be holding the graphics card back so you won't get the best out of it


Thanks! that would definately be the last solution.

TBH you probably be fine with the one you have. But if you have not bought a GPU then look at some of the newer designs. If you want nVidia look at the G210 or ATI look at 4350, 4550 or 5450. All require less watts at peak and 5450 only requiring half of the 8400gs at load.

Here are some benchmarks that include both the 5450 and the 8400gs. HERE.

If you do go with the 5450 make sure its a DDR3 version and there are a few slower DDR2 versions around.

Before doing anything, I'd suggest checking the capacitors on the motherboard that are near the CPU. There's a huge issue with those capacitors where the electrolyte solution is bad, which causes them to swell and eventually burst, which can kill the motherboard, CPU, and harddisk too, if you're particularly unlucky. You can swap the caps over for new ones if you posess the requisit soldering and electronics skillz, although if you can't, and the caps are already starting to bulge, you're living on borrowed time.

It might be okay, though. Give it a check and see. If the capacitors are flat on top, they've probably already been replaced, and you should have no trouble. If they're starting to bulge, I hope you have a Maplin nearby.

It's the GX270 that suffered badly with the capacitor issue, I've not seen any 280's with that problem whereas pretty much every 270 has- the company I work for has hundred of both machines.

I'd go with Gavin's recommendations, Dell tend to be fairly conservative with their power ratings and graphics card manufacturers have their recommendations fairly high to be on the safe side so any of the lower power graphics cards as mentioned should be fine.

The 270 series had it worse, but the 280 certainly did suffer. It's so common a flaw that during my time at Dell, I used to get people calling up (maybe even you - do you ever speak to the Glasgow office?), reading out the service tag, and then encouraging me to try and guess what the problem could be.

No, never Scottish from what I recall - usually Indian and they'd always insist on going through full diagnostics every time even though the fault was obvious. All the 270's were replaced by 280's but despite every single 270 failing (usually 15-20 would fail within a day of each other), not a single 280 ever did. I think if the caps were going to go on the OP's machine, it would have shown itself by now.

Ah. Sympathies.

It might be an idea to speak to your account manager and IT department buyer and see if you can become a Relationship customer, with Glasgwegian support. In Glasgow, we're far less stringent on diags. You've still got to do the contractual minimum of the Dell self-test and report beep codes and status LEDs, but we're happy enough to accept all your diags being done on your own time, providing they're conclusive enough to satisfy. I used to crack through those generic GX270 calls in under five minutes, including full service call booking. Used to do some five or so per call sometimes, too, all within minutes. I was one of the most efficient workers on the team usually, but there's still loads of people in Glasgow who can sort you out very quickly, so it might be an idea to have some words and see what you can sort out, since it could potentially save you a tonne of time.

We changed to the DCDE program (or whatever it was called) so we could order the parts ourselves which made it much less of a hassle, unfortunately changed to Lenovo last year though.

DCSE? But, ey, nevermind. Hope your Lenovos turn out more reliable than than the Dells. Just out of curiosity though, how do you rate their tech support?

Thanks very much for all this support. I have checked ATI cards which have very low power consumption but poor 3D performace. Although I am not looking for great 3D performance yet i got a 8400gs 512MB card so i thought of changing power supply.

Not sure if they've changed the name, Dell Certified Diagnostics Engineer. The Lenovos are nowhere as reliable as the Dells, many machines haven't made it to the one year mark before failing. The machines are poorly designed, poorly built, compatibility is poor (docks aren't compatible across their laptop range) their software isn't optional and it's rubbish and their tech support is poor. The machines seem to be on a downhill slide from their original IBM days.
