Experience with R9500PRO, R9700 and 300W anyone?

[eden]

So, I am here now considering a new card in the next months, but I am also stuck wondering which will do justice in time, without me resorting to a new PSU.

Has anyone experienced OK if not stable useability with a Radeon 9500 PRO or 9700 standard under a 300W PSU?
Mine is an Antec Solution series, P303X.

My system is really light as well:
AthlonXP 1.4GHZ (Palomino)
512MB DDR PC2100
Epox 8KHA+
geForce 3 Ti200
1 80GB WD JB
LGE 16*10*40 CDRW
SB Live
One D-Link NIC and one AOpen FM56P 56k modem.

Unless the monitor draws from the PC, this has got to be light enough no? I feel that at maximum power, it would be drawing 200W, not more.
So what do you guys think, and if you also have been through this, please share!

I could as well for the RV350, hopefully if its performance is up there with the Ti4600 or 4400, as it's 0.13m and therefore no worries there (prolly have Ti4200 power draw), but suppose I could look at the R9500 PRO or 9700 standard.

I installed (at the end of December) a 9500 Pro in my Compaq Presario (pentium 4 1.7 Ghz, 512MB Sdram, cd-rw, dvd, floppy, 80GB Maxtor HD) which has a 250W PSU (which I think is rated based on continuous output, not peak, then again I don't know much about PSUs so I may be wrong) and the card has been pretty stable. I had some graphical glitches about a week after I installed it, but it was nothing that a reboot didn't fix. The glitches have happened a few times since then (once a week or so), but like I said nothing that a reboot didn't fix.

Hmm, it's not a PSU's usual to make graphical glitches. A PSU symptom usually is reboots.

In your case, graphical glitches seem to be a problem of heat. Usually when a GPU is overclocked, artifacts appear, which are caused by a too high clock speed, often overheat. I wonder if that's why. Then again maybe it's only in one game?

It actually happens after the Windows start-up logo on the select user screen.
I haven't had problems in any games. (which include: MOHAA, NOLF 2, Unreal Tournament 2003, et al.)
Also, the computer isn't rebooting on its own, I'm the one restarting it. Rebooting it just seems to solve the glitches.<P ID="edit"><FONT SIZE=-1><EM>Edited by CorpusBiscuit on 03/06/03 00:28 AM.</EM></FONT></P>

Doesn't the Presario have pretty bad case cooling? I saw one while I was taking a work experience in a computer shop, and I can say I think it needed better airflow. That might be the problem, I had also heard that minor variations in power can cause graphic glitches too, but those are sometimes caused by power regulators on the computer's boards and not necessarily the power supply. At least that's the impression I got.

If you remember back to the thread in the other section, I put a 9500Pro with a generic 300W and it seems to do ok. My brother hasn't complained about anything at least.

It's luck of the draw.

50+24+32+110+25+20

Just what you have listed COULD be using up to 261W. The 9500Pro will make that closer to a reality. Generally you only want to use 70% (210W in your case) of a powersupply's possible juice.

Where did you pick up the 110W?!

Ok, checking myself on that list, I have to say it's really screwed up!
I got a total of about 225W, and did times 1.8 as they asked. Lol, the thing got me at 405W, 105W over my limits lol!
I don't recall a PSU of 300W not being enough for such system.
I dunno why multiply by 1.8, but it's giving me a draw of over 300W easily, and it makes no sense.

110W is the motherboard and CPU.

Those are max values. I'm simply pointing out that a 300W powersupply will be cutting it very close. I can't give you an exact answer without putting WAY too much time into this. You could look up the values for each component and break down which rail they use. Then look up how much power your PSU supplies to each rail. Then check motherboard monitor and see if each rail is as strong as they claim it is.

Or you could just try out the 300W and buy a new PSU if necessary.

What was your brother's system anyway, and his PSU brand?

Also, I wish I could know if my PSU's doin' good in the rails, I honestly don't know margins that are good. I tried looking once for such info on the web, but couldn't. So here are them, and perhaps someone can tell me if they're ok: (they are all averages assuming they fluctuate +/- 5% from their current)

-CPU core: 1.78
-+5V: 4.87
-+12V: 12.22
- -5: 0.69
- -12V:2.12
There is a weird meter that I know not of what it is about, and reports 0.03V on the dashboard of MBM5.
I also have a UPS to back my system up in case of failure though that is not relevant.

Correction: My Antec is not a Solution Series but an old PP303XP model.
Here <A HREF="http://www.antec-inc.com/specs/p303xp_spe.html" target="_new">http://www.antec-inc.com/specs/p303xp_spe.html</A> you can find info on it.
I still don't get what combined output is. Why is the combined output of the 12V, 5V and 3.3V 278W?
