I am using a 430W Antec Truepower to power:

A8N SLI Deluxe
1GB PC4000 Corsair TwinX
BFG 6800GT OC PCIE
2 HD
2 Optical.

I am reading 11.75v in the health monitor in the BIOS and also the ASUS Probe software in Windows. Also when I am overclocking I am seeing 1.5v on the CPU core when it should be 1.6v.

The PS only is a 20pin while the mobo is a 24pin. I read that this should be ok with the other power connector in place.

Should I upgrade or worry about this???

Thanks!

It should be OK however you are using a fairly high end system there, and shouhld think about upgrading PSUs soon.

Those voltages might be on the dot. It seems that it is offset by some value. Take multimeter to each voltage rail to get a more accurate picture. You might find that 11.75V in BIOS = 12V on multimeter.

Yeah. I'll have to find that sucker in my house somewhere. Haven't used it since High-School in the 80's!!!

Yes, the hardware monitors aren't all that accurate. IAC, 11.75 is well within the +/-5% spec.

ARRGHGHGHG!!!

I just called home from work and found out my looping 3Dmark2001 crashed at stock settings, no overclocking.

Now I'm starting to wonder if I should just drop the dollar on the PS now because the rest of the system is pretty much top notch or new stuff.

That psu is garbage for a high end system, I had it, OCZ 530 is the way to go.

Probably right but I'm going to wait. I figured out what was causing my problem. First rule of looping benchmarks I'm sure is to not have any programs running and screensaver, etc etc.

I ran for 300+ iterations without a hiccup. Feeling good now.

Looking at the Thermaltake 680W Purepower that has 2 PCI-e connectors and 30A between the 2 12v rails.

I took a look at a couple bigger enthusiast SLI systems such as Falcon Northwest and they chose Enermax so that one may be worth looking at:

EM-EG701-AX is what FN page says but I think it is this one:

Just a headsup: another thing to look for in PSUs is how many memory errors it can bring. Anandtech had a 2002 comparison, and it's something to wonder when even good named PSUs keep coming up with errors after 3 trials. :/ It might not be critical for some, but some folks are picky on system ops and removing those random memory errors that shows up in the event log -- especially those pushing their systems.

I'm not following you. Do you mean unstable power to the dimm slots leads to mem errors? If so I'm with you.

I would get a good quality single rail PSU, as that seems to be what most people are having the best luck with on these boards, especially when using SLI. I have the Enermax Noisetaker 600W PSU and it has been working very well with the system in my sig., so I can recommend it. Other good ones are the OCZ PSU's, look at the Powerstream 450 for your current setup, or the 520 for the future. I would also recommend you read the A8N thread in the motherboards section as it has a lot of good information about overclocking using this board.

I have the truepower 430 and have had no issues with it. In the bios it is 11.71 consistently. Then again, you are approaching the limits for what ASUS calls for in regards to wattage on your system with a 6800, 4 drives etc. I don't think it's a bad power supply, it just may be it's going beyond what it's spec'd for. 26A on the 12 rail is nothing to sneeze at.

I don't know what you're smoking, but Antec makes excellent PSUs. He should probably get more watts just because of all the stuff he's running, but I wouldn't say the PSU is "crap". It doesn't meet his needs, but within its scope, it's an excellent unit.

I had an that psu, its sucks for high end systems, antec is not as good as it once was, look at their rails. like I said the psu is OKAY for a mid-range system but garbage for a high end system. I would reccomend a OCZ 530 watt psu, it should help out with those terrible voltages you're geting. Anything lower then 11.89 on the 12V is not acceptable.

Please stop talking. The rating on all PSU rails should be within +/-5% - for the 12v rail, that means going as low as 11.4v - now granted, my PERSONAL spec is that all rails must stay within +/-2.5%, but that's just because I like a really fat cushion.

If you think Antec makes crap power supplies, all your credibility just went right out the window...

Like I said , its not such a good powersupply for a high-end system, antecs Psus are not that great, thats all i'm saying. What do you think will happan if he trys to add another 6800GT? That psu will probaly drop to 11.60. Im sorry that my 11.89 or higher got you mad, I like my parts to be good quality.

Yes, we know what you're saying. The problem is, YOU ARE WRONG.

Look here: AnandTech's 4 way shootout between Antec, Vantec, Enermax, and Thermaltake's PurePower:

http://www.anandtech.com/casec...howdoc.aspx?i=1774&p=9


Guess which Power Supply was the BEST PERFORMER?

If you guessed "Antec", you are RIGHT!

Like I said, stop talking before you do any more damage.

Yes, running 6800GT SLI on a 430 watt power supply is stupid, but that has nothing to do with the quality of the power supply. Running 6800GT SLI on a 420 watt OCZ is stupid too. Does that make the power supply crap? No, it means you're trying to build a PC with the wrong hardware.

If you try to run an FX55/6800GT system using a 200 Watt power supply, it doesn't matter who makes it, it's not going to work.

I could care less what your review says. He is geting 11.75 on the 12V, he has a SLI motherboard, he might add another 6800GT, his psu will perform even worse then what it already is. Stop posting these links thinking I even bother clicking on them.

Thus all goes back to my first post, IT'S NOT A GOOD PSU FOR HIS TYPE OF SYSTEM, in this case is high end.

go bouziki! yu win.

ya know, first you sez antex is CRAP OMG THEY SUCK THEY ARE BAD BAD BAD

den joo say "it's just not a good powersupply for his type of system." you flip flop more than mah sandals.

oh yeah, person with problem, that powersupply will definitely power the system you have now, and when/if you get a second gt, then i would worry about upgrading. by then, bigger, better, beastier power supplies will be available for cheaper and you will save money :).

laff-o no /end thread i'll be at class when i come back i want a fresh volley of insults.

I never said it sucked, all I said was they were not all that great. Learn to read.

PS: Learn to spell.
