zxc 0 Posted March 22, 2002 Hi everybody! As I'm experiencing many crashes with my pc at the moment, I realise more and more that it may not come from ofp but would be more of a hardware pb. As I'm constantly looking for the solution to my pb, I discover more things everyday and try to share them on this forum so that others don't experience the same s**t! I've found out that the power supply plays a very important part in the stability of the system when it comes to big cpu's like athlon 800MHz or higher. Go to this site and read the next few pages, especially the comparison tests of some power supplies, it's scary! U realise that the power supply can well be the source of stability problems when u think it may come from your graphic card/RAM/drivers. Also, u realise that some 250W power supply can perform much better than 400W ones! Well, I hope it's gonna help some of u. Share this post Link to post Share on other sites
dvrabel 0 Posted March 22, 2002 Odd review. Why didn't they just measure voltage levels during use? David Vrabel Share this post Link to post Share on other sites
Mister Frag 0 Posted March 22, 2002 There is more to 'clean power' than voltages -- the amount of current delivered, response times to load changes (modern systems use switching power supplies), tolerance of spikes and drops in the input voltage, cleanliness of the sine waves in the case of AC etc. Share this post Link to post Share on other sites
shadow 6 Posted March 23, 2002 I also got a stability-problem similar to Zxc's. The power-supply fan hardly starts spinning. When I slap it around a bit it usually starts spinning When my computer has been on for an hour or two, OFP starts freezing every few minutes. Guess I got a good excuse for buying a new computer hehe Share this post Link to post Share on other sites

Certainly the tests would involve more than a digital voltmeter... David Vrabel ps. All PCs have used switch-mode power supplies (even my ancient PC XT had one).

Mister Frag 0 Posted March 24, 2002 I guess they tried to show how the quality and performance of a PSU affects real-life situations, and how a system that can boot the OS and maybe run Office won't be able to run Quake without crashing once a high-end AGP video cards starts putting more of a load on the PSU.
