Power Supply and Overclocking?

Hello all,

my question is if having a cheap ass PSU will limit your STABILITY at a certian overclock? Let me elaborate. my nice antec 350W blew up (and took the mobo with it)

So until i can get back to my roomie in college in 2 weeks im stuck with this noname 300W psu. it powers everything (well everything if you keep in mind i have 4 of 5 HDDs unplugged.

But playing around on my K8N Neo2 and my watercooled 3200, i have it at 2.5Ghz and gets into windows and has looked stable for the past 2 hours. but when i play with prime95 it gives me errors after about 5 minutes? I dont have the data to say if it was stable on my Antec at this speed, i never played with it like that.

So this is just a general question: crappy PSU = instability in prime95 (but everything else stable)?

Thanks
Jeff
 
its very possible that the PSU cannot provide enough power to keep a stable OC





















i know mine doesnt....same as you...cheapass generic 300w
 
i figured as much -- hell i have a 9800Pro AIW in here and 5HDDs, and a dvd burner so looks like ill be waiting about 2 weeks to score me a sweet ass antec (hopefully neopower)
 
The problem with generic PSUs is that if it says it's a 300W PSU, it acutally only puts out about half of that. So with a 300W generic you are only actually getting about 180-220W depending on manufaturer. The nice thing about Antec PSUs is that they actually put out whats on the sticker.

True but its not because it doesn't put out 300w at all, it justs puts out 300w at 0 degrees C or some crazy low temperature. As Ice Czar will tell you what makes PC Power and Cooling so good is that the power generated is rated for a higher temperature making it remain at a constant Wattage, with overclocking your increasing the wattage in the processor making a cheap psu even more unreliable as your generating a higher temp and higher wattage on an Indirect Graph (wattage to temperature.)
