Hi,
If your Pentium 4 is Socket 478 and between 2.4 and 2.8 GHz, it is most likely a Northwood, although there is a slight chance of it being a Prescott(The 2.8 GHz version was produced for the 478 socket). (You can run for example CPU-Z to determine its exact type)
The 185W PSU is on the lower side of what I expect a P4 class machine to have, I generally like at least a 200W or above PSU for them, although if it hasn't aged badly it is possible to live with it, but careful consideration needs for the power usage of the video card as high-end cards with a P4 on that PSU will put the system over the power limit.
Without knowing more about the system and having a possible small power margin by the PSU, I would recommend a Radeon 9600(The one without the Pro or XT postfix as those might put the wattage of the system above the PSU limit especially considering the possible ageing of the PSU), but better recommendation can be made if you check the exact CPU type, the amount of RAM in the system and whether you consider upgrading the PSU or not, as anything more powerful than a Radeon 9600 paired with a P4 will most likely overstress a 185W PSU.
Unfortunately, the power supply is the original IBM one for its case and cannot be replaced, but it is of excellent quality and could hold up well even over the years.
Doing some research myself, I found either the Radeon 9600 or the NVIDIA 6600.
But the NVIDIA is incredibly expensive; for that price, I'd buy a 3060 8GB!
The Radeon 9600, on the other hand, is available for a fraction of the price on eBay or local sites.
Which Radeon 9600 variant would you recommend? And why?
Sorry for answering a bit late, but IRL issues have kept me away from this forum for a while.
Just to not overstress the PSU I would recommend the base variant or maybe the one with the PRO suffix, while the XT version is more powerful I think it might put the system over the PSUs limit at full load especially the 256 MB version. The only one that I don't recommend is the 9600 SE, it is basically the same as the base version, but they have reduced the memory bus width to half 128->64 bits and only slightly increased the memory frequency, it is not as good of a performer as the other 9600 cards.
An interesting one is the TX variant(Not a typo, it is called like that, so don't accidentally mix this and the XT 😁), this is, in my experience more rare than the others, and unlike the other 9600s it is based on the R300 chip not the RV350 or RV360, it has more cores but a bit older and it also has lower clocks, so it has a different "performance profile" than the others.
For the manufacturer, as this is a mid-range (Or in the 256 MB XT version case a mid-high tier one), I don't think that the manufacturer is that important as long as it is not some no-name unreliable one, I had 9600s of various editions from multiple manufacturers and they all performed without problems. One thing to note is that these cards are available in both active cooling and passive cooling variants, and sometimes the passive cooled ones are under-clocked a bit, generally not by that much that you feel the performance difference however.
