Robanton 600 Watt Powersupply

12V is way more important than the other two rails, and is most often the one that's skimped on with cheap PSUs. Even with a loaded system you aren't going to go over like 25 or 30A on 5V.
 
Reason I ask is my ECS K7S5A needs more power. I have got a Allied 450 True Power I got from Newegg and it is not cutting it.
 
Uhm, what kind of processor and parts are you running that a 450W Allied isn't enough? It is sort of on the low end at 18A on the 12V line, but that should still be enough unless you've got more than two hard drives and CD drives.

16A would definitely not be enough if the Allied PSU isn't enough. However 25A sounds more likely for a 600W, even a cheap one.

How much does this 600W cost? I've never heard the name. I'd rather go with an Antec True480 if I was concerned about reliability and quality; it has a little less power, but not a whole lot less and certainly should be enough.
 
I have one and the Data sheet states 16A but the sticker on the Metal has 25A which I'm inclined to believe and Doc @ Lost Circuits did a review on this to verify it. I know the 400wt comes in 2 flavors with the older ones (Powmax) being 25A and can be found @ eb. The only complaint I have so far is how the 2nd fan is mounted.
 
Even on a high estimate I don't think you're exceeding 18A on the 12V line, or even 16A, even with everything running at peak draw. You don't exactly have a super-loaded system, there's no reason you should need to use a 600W power supply. All the other rails are supplying plenty of power for your components as well.
 
As I recall, the K7S5A uses the 5V plane to power the CPU's power circuitry, not 12V. Empirical findings are that you want a fairly healthy 3.3V + 5V combined output with this motherboard. The Allied 450W that's shown at newegg would seem to have what it takes (230W on combined 3.3V + 5V) but maybe the regulation is not good, or maybe the real problem is elsewhere. What problems are you having?
 
I doubt the K7S5A uses 5V since every Athlon board has used 12V and it is what AMD specifies. Where might you have gotten that information? It seems difficult to find ANY information about that sort of thing regarding mainboards or any other type of device. Original boards used 5V for the really ancient processors like 486's, then when Intel moved to dual-power planes they started using 3.3V. I don't see ECS moving a step back in time with a single board rather than building it to work with newer PSUs.

Even if it did use 5V, the Allied PSU puts out 50A, and the processor shouldn't be going over 18A of that at peak, and even with somewhat less than stellar regulation, I think it should be able to handle the requirements.
 
600w? you are joking right? just buy a good quality psu like an antec true430 or enermax 431w.

look at the first system in my profile, ive got it all on an antec true430 and i dont think im even close to overloading it.
 
It may very well just be my motherboard. My 3.3v, 5v, and 12v are all underpowered. Specs at this moment 3.2 on 3.3,4.92 on 5, and 11.86 on 12v. That is just sitting idle. Cold boot problem. Allied PSU worked great for a month and know is giving me problems. Same thing I had with my old PSU before the Allied.
 
right now my 3.3/5/12v rails are at 3.28/4.89/11.49. ive got f@h running, so cpu utilization is at 100. i saw the same voltages before this last upgrade (used to have 1800+ on 8k3a+). to see my system stats right now just check my profile. with these voltages, i have not seen even a bit of instability in the past several months.

On the Intel Active Monitor that came with my board it measures the voltage of each plane and has a little dial for each that shows safe tolerances. For point of reference, according to the monitor, anything from 11V-13V for the 12V is fine, 4.25V-5.75V for the 5V, and 2.5V-4V for the 3.3V. All those values are in the green, there is yellow outside those areas which would be time to start looking for a new PS and then red outside that. Your measurements are well within those limits and could very well just be slightly inaccurate measurements that might be right where they should be. I run a system with a lot more stuff in it than yours on a 330W Antec TruPower and all my voltage measurements are basically right where yours are at (11.875,4.974,3.3). Whatever problems you are having, I doubt they are because of your PS. If you want to upgrade to a higher quality PS, knock yourself out, but you absolutely don't need to throw money away on a 600W PS.
 
I went ahead and purchased this power supply off of ebay after my chieftech 340W Power supply was acting up. I haven't had any problems and currently its running rock solid for me, powering:

ABIT SR7-8x w/ 1.8 ghz Intel P4, 512 DDR
80G Seagate Barracuda
60G IBM Deskstar
2 9G SCSI Cheetahs
CDRW Drive
DVD-ROM Drive
Radeon 9700 Pro

Other stuff:
4 case fans w/ baybus
Soundblaster Live
Mylex extremeRAID 1100 SCSI RAID Controller
NEC Multisync Monitor

I haven't had any trouble with voltage specs or consistency, it has worked well for overclocking also.
 
Yeah Intel boards are just more stable. They are no fun. Always working. No tinkering. What fun is that. Anyways, I appreciate those who have posted. I am kind of resolved to the the point that no matter how much money I throw at this board it is never going to be rock solid. Next time I will buy a better quality board. Which will not be long since I uprgrade motherboards about every six months.

Do you guys think that my Allied True Power 450 will be good for one of the newer processers and boards?

I think I got that information from Peter, who seems to have good depth of knowledge on the subject. I'll ask him if I got my facts straight or what.

 
I'm using an Antec True330 with an A7N8X and Athlon XP 2100+ Palomino. Perfectly stable and plenty of power. Even with your extra drives you should be okay with the Allied.
