Hi, all. Lurking Tom'sHW for 10,000 years now and have been able to get any questions answered simply by searching; I finally have to post since I have a question with a few angles.
I am bringing home TWODell Inspiron 620S from the office to use at home. Yeah, they're old, but they were almost never used and are just about pristine. These are slim-tower units with small, 250w PSUs. My intent is to use them for general purposes including browsing, vid watching, very light photo editing, etc. I don't play any "hot", current, graphics-intensive games, but do play some light-on-graphics strategy games such as Crusader Kings II, Hearts of Iron III, and some old, lower-end single-person games such as ES-Oblivion. But that's about it. No heavy hitters like CoD, DeadSpace 3, Diablo III, etc. These two PCs are identical and critical specs are shown below:
Now I totally realize that spending nearly any amount of money on upgrades to these units will likely be money best thrown at a new PC. But (!!) I also have access to the following parts available from my office:
Western Digital Caviar Green 1TB SATA 3.0 (3 Gb/s) - Internal Hard Drive (WDBAAY0010HNC)
Western Digital Caviar Green 2TB SATA 3.0 (3 Gb/s) IntelliPower 3.5" Desktop Internal Hard Drive (WDBAAY0020HNC)
Western Digital® Caviar® Black™ 1TB SATA Desktop Hard Drive (WDBAAZ0010HNC)
More compatible RAM to make 8GB on each PC (I'd have to buy this, though)
The basis for my question essentially revolves around the PSU. I already know that vid cards require a certain amount of juice to function, but I'm unaware whether or not the same is true for more RAM, larger HD, etc. Assuming I'm NOT going to upgrade the PSU, here are my questions:
1. Will any of the aforementioned vidcards work with the the limited, 250w onboard PSUs? If so, which one would be best (i.e., the 210 or the 8400)? 2. Can I upgrade the RAM to 8GB without affecting the power requirements for #1? 3. Can I upgrade to any of the Hard Drives mentioned without affecting the power requirements for #1 and #2?
If anyone can answer these questions, I'd be much obliged! Again, the only thing I'd be shelling out for is extra memory and that wouldn't be too much of an outlay for these two almost completely-unused machines. Thanks for reading.
Much obliged kisianik. Thanks for the clear explanations for all aspects of my question. A similar post I made in the graphics cards forum supported yours as well regarding the G210 being a better choice. Thanks again for all your help!
