The 4500S has a "slim" power supply, and it was 180W. It is their Dell Part# 1N405.
There is a company which sells "slim" Dell 1N405 replacement PSU's with 200W being the standard size.
Priced at $40, for an extra $20 they will upgrade it to a 270W version. If it really is inadequate power that has been the problem with the earlier two ATI PCI cards I tried (1GB HIS HD5450 and 512MB VisionTek HD3450), one would expect a 270W PSU to be the answer. Both of these cards failed and have been returned.
I will wait to see what happens with the third card I'm now going to try, that Sparkle 256MB GeForce 8400 GS
, which is an nVidia-based product. A Dell owner of their 2350 (which has a 200W PSU) says he uses that 8400GS without any problem. Fingers crossed it will work in my 4500S.
If it still fails, I can always try upgrading the PSU with this replacement at the 270W flavor, for $60. It's a pain to replace a power supply, especially in a slim profile case like for the 4500S. But it can be done.
I know, it seems crazy to invest any significant money in a 10-year old machine rather than just spending about $300 on a modern Dell Inspiron 660s
with its i3 CPU, modern graphics, large SATA hard drive, and 4GB of memory. I believe they've been discontinued by Dell but they're still available. I bought one for my mother over the summer to replace her old machine that had died, when I discovered it on sale at Best Buy for $330. Obviously, a terrific value at $300.
Thing is, this all started from the death of the monitor on the 4500S and replacing it with a 20" 16:9 Samsung LCD monitor, and the desire to run it at 1600x900 resolution. There was never a plan to upgrade the whole computer itself when the 4500S was perfectly adequate... mostly, or with just a few hardware upgrades.
I'll decide what next to do when the 8400GS card arrives next week. If it works, case closed and I'm finally done. Otherwise I'll have to stop and ponder the next move.
