So I have this old eMachines, and have come to the conclusion that it crashing so many times is from the insane amount of dust + its crappy SiS <something> integrated gfx chip. Well, I plan on fixing up that dust, reapplying some thermal paste (AS5), and adding a brand new Radeon 9800 in it (AGP, 50$, should play most stuff on medium settings). Now, the problem is, the powersupply is a crap eMachines 250W that is ~6 years old. I have a 500W -unused- PSU just sitting there in my box [that is, box of random stuff that I have lying around] (ATX v2.2 I believe). It has 24 pins, and enough power for that eMachines and it's new 9800. The question is, if I were to get a 24pin-20pin adapter and hook everything up, will something break? The motherboard is a Foxcon, socket A with a 8x AGP slot. Don't know the exact model, but the chipset is an SiS (and so is the integrated gfx chip). I think it _should_ work, but is it possible that the PSU will somehow...... over-power it or something of the sort? I can't afford to break anything, so I won't even try if you think it won't work. All replies welcome! Thanks!
