Current PSU up to the task?

Hey every one,

I've just upgraded my system from a dual core Opteron 165 @ 2.7ghz to a Triple core Phenom 2 720, everything seems stable, but I can't get the CPU to overclock to more then 3.2ghz triple core or 3.1ghz quad core. Might just be a all the CPU has in it, but was wondering if my current PSU is still up to the task.

PSU is an Antec Trupower 2 550w.
Specs are:

Model - TPII-550
+5v - 40A
+12v1 - 19A
+12v2 - 19A
+3.3v - 32A
-12v - 1.0A
+5v SB - 2.0A

12v1 + 12v2 Max Load - 36A

Thanks in advance,
Dave
 
Hi and welcome :)

Are you by any chance running SLI or Xfire, and if so, with what videocards exactly? If you have 12 HDs in there, it could be time to worry as well.

On the other hand, if you are running just a couple of drives and one video card, you are absolutely fine with the Antec and not limited by it one bit. It is a great PSU, at least it was when it came out, so I recommend sticking with it and spending on other hardware maybe, that is if you dont need lots of extra video cards and drives :D
 
The Truepower I and II series as well as the Smartpower series were well known for their above average death rates due to a poor choice in caps and cooling design. In more specific terms, Antec/CWT specified/used caps that did not respond well to heat. Unfortunately, Antec made the decision to have the PSU fan only ramp at really high temps in an effort to keep the PSU quiet. However, just medium to high temps were enough to screw up the caps so really high temps were murderous. Over time, this degraded the quality and performance of those PSU series.
 
Get a DMM if you don't already have one. Take the CPU to it's max overclock. Load it with orthos or whatever and check the voltages. If they are holding steady then chances are very good there is nothing wrong with your PSU.

Again use an actual digital multimeter. BIOS voltage reading are pathetically useless.

I wish I had read this a few years ago... I've had two truepowers die on me. :eek:
 
And I guess I was lucky never having any stability issues with mine what so ever :D

...what does an "above average death rate" entail? just curious..
 
Thanks for all the replies. :)

I'm only running a single 9800GTX+ video card (I was running a pair of them in SLI on the previous board with no problems), also only have 2 HDD's in raid 0.

As suggested, I tested the PSU with a multimeter.

3.3v - Idle-3.36v Load-3.34v
5v - Idle-5.05 Load-5.04v
12v - Idle-12.08 Load-12.07

Looks like I'll hold onto this PSU for a while longer.

Thanks again,
Dave
