New PSU needed? Advice.

3.3V: 3.38
5V: 5.03
12V: 11.8

About your PSU, I think the single fan version doesn´t have active PFC or PFC at all. Check the reference. There´s a HPC-360-202 that has passive PFC and a HPC-360-102 that doesn´t have PFC at all. I don´t really know how PFC is that important, but it maybe has something to do with it.

Can´t you borrow another PSU to try out?

PFC does absolutely nothing to the stuff that's BEHIND the PSU, it's only good for the power grid.

That's what I'm going to do. Just need to find one.

... and your pocket book. PFC not only cleans up what it returns to the AC line, but by smoothing out the phase, your electrical utility Co. will also see that you are using less electricity (based on how power meters work) for a given amount of work.

I have an Antec TruePower 550ESP 12V. Very quiet and very powerful:

12V : 12.038
5V : 5.053
3.3V: 3.298

My 12V line is only 11.67V...

[Wombat]

Yeah, but that's also according to your motherboard, yes? Until you check it with a proper meter, I wouldn't worry.

Also, I believe that acceptable ranges are +/- 10% on the 12V and 5V, and +/- 5% on the 3.3V. Your 12V is only off by 3%, assuming your MB is accurate.

The negative lines aren't a big deal, they're just used for signalling, not feeding anything. My -5 is at -5.14, and the -12 is -13.6 (high, but harmless). This is all according to my MB though.

I agree with Wombat. That 3% off is much better than the +-5% variation even premium brands offer.

Well, what speed are you running the CPU at?

What's your VCore set to? Try upping it? (You've got an Epox board...)

[Chrono_Wanderer]

My Topower 370W

12V: 11.977-12.038
5V: Constant 5.053
3V: Constant 3.392
VCore: 1.584... i think that's a bit too high... (I thik I have to do something in the BIOS???? Advice please)

Here is the proof tho...

edit: this is the Topower 370W I have... best buy ever. Its a lot cheaper than Enermax too (and its even better IMO)

I don't want to ruin my CPU, the 0.13 AMD CPU's are delicate regarding voltage but I crammed it up a notch to 1.75V. See how it goes. BTW I'm trying to get my 2500+ to run at 3200+ settings(2.2GHz)

I'll play around, I'm just glad that the PS is more or less taken out of the issue.

I tweaked my Antec Truecontrol to 5.00 and 12.00 with a multimeter hooked to external molex connector.

Based on delta between Motherboard and PSU (-1% on MBM), 3.3 is in specs too, board shows 3.47, which is 99% of default, MBM shows 99% of what multimeter does on 5V and 12V lines.

Abit boards default to 3.5.

The 300W smartpower (MBM results) is 3.57 (again Abits default to 3.5), 5.00 and 12.10

I have a PC Power Cooling (510XE) to power a dual Xeon setup. The voltages supplied are extremely stable and virtually spot on (specs allow for a 1% deviation for all lines, except for -5V and -12V for which the specified max. deviation is 5%).

They also provide for custom options that might be interesting for overclocking (I don't overclock, so I can't say, but one of the options is external voltage tweaking):

PC POWER & COOLING is having a sale on their 400WATT SUPER-QUIET power supply. Compare the specs, it also has the most stable line voltage around

5V rail is at 50A

Just wanted to note that this power supply is giving up the ghost.

I came home the other day, and the exhaust fan on the PSU was running intermittently. Today, the fan is on, but the PSU exhaust is hot, and the case is 10-15C above the usual.

I'm considering a Seasonic Tornado/Silencer model. They're like $85, though.
