Will signal strength of PS influence ocing ?

Well continuity of signal levels and clearness of signal coming from the PS, will it keep me from ocing my 1 GHz Tbird ? It's a pretty "old"(1 1/2 years 24/7) 235 W generic PS. Works now pretty well with K6 III 450, Geforce 256.
 
I think the Power Supply terms you are looking for are Voltage Ripple and Voltage Regulation. Yes, they can and do effect Ocing capability. In fact, the total output of the supply, 235watts, 250watts, 300watts, actually mean very little. Clean, well regulated power is much more important. This being said, 1GIG BIRDS are power hungry, overclocking adds to power drain so you should look at an AMD approved supply of 300watts.
 
Specs of new PS(400W):
<<Technische Details:
+ 5VDC / 40A
+12VDC / 15A
-12VDC / 1A
- 5VDC /0,5A
3,3VDC / 22A
VSB /1,5A
Should be OK ?
 


<< The ps does not really &quot;signal&quot; to anything, save the power good line >>


Ahem, meaning ? Care to explain ? 😕
 
He means that the PS just supplies power, and does not do any signalling. However, DaddyG seems to have it right -- signal quality is more important than power capacity. Unfortunately, voltage and current ratings given on most power supplies don't tell you anything about how clean the signal is.

I would expect that a new 400W supply would be ok in all aspects.

Besides, doesn't the motherboard regulate the voltage to the CPU anyway?

Nickdakick,

The current ratings that you posted all look very good. One important rating for TBIRDS is missing. Thats the total wattage of the +5 and +3.3 combined. These two voltages combined, are limited to less than the total. For example, the +5 rates at 200watts and the +3.3 rates at 72.6 watts. The combined total would NOT be 272.6watts. Since both voltages are generated from the same part of the PS the combined total would like be closer to 200watts. This is still much higher than the recommended total of 145watts that AMD specs.

Your specs don't list regulation percentage or 'ripple' percentage but I'm sure that you will be OK.
