Hi Folks!
I spent a while struggling with a PT880 system that kept crashing and then staying frozen for several hours. After guessing the 300 watt PSU could be the problem and trying out a different PSU - unfortunately, only 350 watts - and getting similar instability but no more freezes, I've pretty much concluded that I need a better PSU. (But just to make sure, I've also RMA'd the mobo.)
Anyway ... I need to choose between two PSUs: the TSP 420 (420 watts) and the TSP 450 (450 watts - with a lot more on the 12v line). What's your call: Do you guys think the TSP 420 will give me enough juice to run my rig or do I need to take the more powerful unit?
Demands: See below. Note, this is a Northwood CPU, not a Prescott. But I have a softmodded 9500@9700 running. And I'd like to be able to do a *modest* bit of overclocking on this system - say, maybe from 2.8 to the 3.4 - to keep video filters purring. Otherwise, my sig tells the story.
I've dredged up the specs on both PSUs:
1) TSP 420 (roughly translated):
ATX Netzteil AMD/ Intel P4
420 Watt Total
220 Watt combined (+3,3 and +5 Volt)
180 Watt kombinierte (+12,0 Volt)
aktive Leistungsfaktorkorrektur (PFC)
maximale Belastbarkeit der einzelnen Schienen:
+3,3 Volt: 26 A
+5,0 Volt: 42 A
+12 Volt: 18 A
+5 Volt Standby: 2,5 A
This model has great reviews and can be had at very good prices. There is a newer model out, the TSP 450, with the following specs:
2) TSP 450
Gesamtleistung 450 Watt
+3.3V&+5V: 220W
+3.3V&+5V&+12V: 430W
+ 3,3 Volt 28 A
+ 5 Volt 45 A
+ 12 Volt 22 A
- 5 Volt 0,8 A
- 12 Volt 1,0 A
+ 5 Volt Vsb 2,5 A
This piece is newer and a lot more expensive. Not much info out there yet, no reviews - but it seems to pack a pretty big punch.
If I can count on the 420 model, I'd like to go with it. But after my expereinces with the 350 Zalman, I really, *really* don't want to put myself through any more grief ...
Thanks for any advice!
Mike
