Radeon 9800/GF 5900 on a 200 watt PSU?

  [DELETED] 02:29 29 Dec 2003


I have had my Hewlett packard Pavilion 434.uk pc for about 10 months now, and I would like to upgrade my radeon 9000 cards that sits in it - to a radeon 9800 - or a geforce FX5900. It is a Pentium 4 2.66, and it has worked well so far, "7584" is my 3D mark 2001 SE.

Anyway I have a 200 watt PSU fitted, click here to see the model I have (1956F). WOULD THIS 200 WATT PSU run a radeon 9800/G-force FX5900 without any probs?, because I have a Micro ATX case (with the Micro PSU too, I can't seem to find any Micro PSU (mATX) on the web anywhere that go up to 300 - and beyond, anyone know if they make them?. Failning that, would it be possible to fit (one way or another) a conventional PSU into my micro case? - and would the power supply be the only problem (IE: - would i need more fans etc)

Is there anyone else around here running an "high-end" Graphics card on a PC like mine (Hewlett packard in my case, but could be Compaq, packard bell, etc.

Hope someone can help!:)

TIA (Thanks in Advance)

Micro ATX PSUs are difficult to find. I know as i have to try and replace the Tiny ones that are no failing left, right and centre. Two solutions. 1) Buy from USA for best part of $100 or 2) New case and (at least) 350 watt PSU.

Personally with a P2.4 and that G Card i would get a new 400 watt PSU first. Micro ATX cases can't be (easily) modified to take a newer PSU so i would look at a new case and PSU.

It is a 2.66 and has a Radeon 9000, plus CD writer, 5400 60 Gig hd, 512 MB Ram, DVD, and the 200 watter I had came as standard. I was going to get a new PSU - and maybe just make it "fit" the best possible way!. Would everything be ok if I got (say) a 400 watt PSU in - and not have to worry about anything else (fans etc)

The FX or Radeon would have its own fan so you will not need anything else other than the upgraded PSU.

I am surprised the machine came with only a 200w PSU with that spec and you most certainly would need the upgrade for either of the two cards you mention.

Well don't be too surprised bremmer, only the biggest computer company (HP) in the world dishes em' out in there millions! I got it from PC world (online) and there are Radeon 9800's on sale in pc world, so I wonder what would happen if i ordered one from the same place as my PC - and put it in - and it didn't work??? - would I be eligible for a return on it i wonder? - afterall, it doesn't say "300 watt power supply required for this item"

So then, If I ordered one from here, would I have perfect rights to send it back?? - or maybe not so easy to do with an online purchase?.

Thanks all for the replies

use this little calculator to find out the power you need click here

i would say at least 300 - 350w minimum

"afterall, it doesn't say 300 watt power supply required for this item"

Funny you should say that

Have a look at the ATI site
click here

"Consult your system builder or OEM to ensure your system has an adequate power supply. Otherwise, ATI recommends a 300-Watt power supply or greater to ensure normal system operation where a number of other internal devices are installed"

It seems I've been running my pc PERFECTLY for 100 months on 100 watts less than required. (doh)

Forget I'll sort it myself

Yes Bremmer, on the ATI website yes, at PC world no.

its only a rough guide AnthonyB.just though may help.

Thanks Huggy, its just that a computer I configured that would be say 4 years old (Duran), no Cd writer, 32 GFX etc, still requires you need over 200 watts!.

Anyway, i have 200 watts, and according to that guide, it shouldn't even boot up my specs again:

Pentium 4 2.66 533 bus
Radeon 9000 64MB
56K Modem
MOBO (6577 I think)
Fans (here and there:)lol
Floppy drive
DVD Drive 16X
CD writer (48x12x48)
512 MB DDR RAM 2700 (1 stick)
Some other things I've probably missed!

My monitor is powered seperatly though, and the Radeon 9800 on the Guide chart only need 19 watts more (35 for my radeon 9000, and 54 for a 9800).

I also ran some tests. I scanned my disk, Burned a CD, and opened as many programms as I could, I then run 3D mark 2001 - but no crash. I wonder if it has something to do with the power supply quality rather than quantity? - don't these "Shuttle" systems that have 200 watts in a small case run Radeon 9700/9800 too (iv'e seen people with them in on the web that is).

I've been to other forums only for them to recommend me a 5 bedroom house for a single workin mother!
