whats the point? no one can even build a computer that gets anywhere near 750watts.
lets say you do an SLI setup with x1900xtx's. i think their rated at 120watts each.
add in 100watts for a new core2 duo motherboard/cpu/memory.
lets say you get 4 hard drives in like raid 0+1 that are 10k sata, your lookin at around 15w each, so 60watts.
2x optical drives at 10watts each, so 20watts
sound card: 10watts
total: 430watts, there about? a 500w psu would handle it with ease. and this is the absolute pinicle power sucking of modern hardware.
this is also load power consumption, so idle would probably be in the mid 300's or less

Seriously, PSU companies should stop supporting these idiots by making such high power PSUs.

All I want was to reply at question above about overclocking and consumption, but maybe it's not time to mix silence computing with extreme overclocking, even there are some interesting results on both sides.
Sorry for this offtopic.
Actually this thread can help shed light on the assumption that overclocking requires a big fat PSU, which draws more power and results in more heat/cooling/noise. An OC enthusiast who also wants to minimize the cooling needed and thus noise can see that so long as the various voltages are stable a 500W PSU is plenty for most OC needs (in theory). Interesting info!
Actually those wattages are from the AC at the wall, not the power output of the PSU. PSU's are rated in watts based on how much power they can output in DC. So lets assume for a moment that he has a good PSU that has 80% effeciency at all loads. That 417w is really only 333watts output. So he can easily run that OC'd system on a 400w PSU.burebista wrote:I quote (translated) from a post of a hardcore OC-er on one of our forums.

I have a feeling his newfound ability to OC to 5ghz had alot more to do with the dry ice portion of those 2 changes, than the new PSU had.
Burebista, your anecdote was very illuminating, there's no need to be apologetic about it. I don't think mantralord was referring to you personally with the "idiots" comment, it's all moot anyway seeing as companies will make anything as long as there is a demand for it (I could give some rather dubious examples but they are R-rated so probably not suitable for a family forumAll I want was to reply at question above about overclocking and consumption, but maybe it's not time to mix silence computing with extreme overclocking, even there are some interesting results on both sides
).Not quite. In first session with Antec TP2.0 550W he use dry ice too, but it seems that that PSU reach her limits (I believe that have something to do with crossloading), but with that Epsilon monster all was smooth.Aris wrote:I have a feeling his newfound ability to OC to 5ghz had alot more to do with the dry ice portion of those 2 changes, than the new PSU had.
@jaganath I don't take it personally, but that OC guy is moderator on one of our big OC forums, and he know what he's doing.
I hope that it's my last offtopic...
From the minor amount of reviews out there, it seems this may be a decently quiet psu. Of course most seasonic models tend to be pretty quiet in the first place. And it definitely is seasonic oem, if you check the ul database, the 610 and 750 psu's are under seasonic with the same exact specifications. I'm glad they're finally putting out some good high efficiency psu's though...not everyone needs 1% voltage regulation methinks.Ender17 wrote:anyone have opinions on this PSU?
I know it's made by Seasonic, do you guys think it will quiet at all?
I would get a Corsair or M12, but I really need a custom wire harness
my current PC Power & Cooling 510W is way too loud
I don't mind a little airflow noise, but this damn buzzing has got to go
My opinion is that unless pc power's silencer is cheaper than the actual seasonic models, you might as well buy seasonic itself...especially with the new energy s12 and m12 coming out this month.

Sure, he (or she) only uses his PSU to reach those speeds until the dry ice evaporates, but you also have to consider all the other "LOL BLUE LED OMGLOLOL" overclocking script kiddies who look at this and think that they would be cool too if they had a 700 or 800W PSU. Therefore, an alarming amount of people actually do run an A64 3200+ with a 700W GameXCrap PSU or whatever, not knowing that their system uses maybe 15% of the capacity of their units. We are all aware of this trend, though.burebista wrote:With all my respect for your opinion, I must say that I'm dissapointed by your words.mantralord wrote:Seriously, PSU companies should stop supporting these idiots by making such high power PSUs.

We also have to look at the utility of all this overclocking. It takes lots of overclocking to notice a tangible speed boost (unaided by benchmarks), and in the end you probably only get 15 extra fps in WoW or whatever. Desktop computers already account for a significant portion of power consumption, so there is no reason why we should have these people routinely doubling their power draw just for fun. And don't get me started on moronic idea of SLI and quad-SLI.
Limiting PSU's to 250W would make the world much less annoying. Much in the same way that banning cellphone ringtones, car modifications, or laser pointers would make the world much less annoying.
Limiting PSUs to 250, that's a very exciting idea. I think we should probably have gone with this idea some time ago, limited processors to 25 Mhz, since that was four times as fast as my first computer, and 6Mhz was just fine. And who needs more than sixteen colors? I had _one_ when I started. I can't imagine a world where we would need more than a 10MB hard drive, but I guess we can go to 20 for the sector wastemongers out there. 1.4MB on this little disk thingy? Nah, let's all just stick with five and a quarters, the new ones don't even have a sleeve to write on.
Then we'll start in on the cars. Limit them to 50 miles per hour, 20 miles per gallon, 8 gallon tanks. That way nobody is tempted to use too much gas. Or maybe we should just go after people. Nobody can have more than two kids.
In other words - unlike burebista, I have no respect for your opinion.

You know, those are all pretty good ideas. Sure, we'd be giving up a few freedoms, but you only have to look at modern life to see the alternatives: Counter-Strike, blue LED fans, overclocking, 1KW power supplies, MySpace, L33tT WAREZ BITOTORRENT, ringtones, emo, car modders, case modders, gigantic side panel windows which increase performance roughly 300%, Maddox, audiophiles, bloated software, application skinning, Fatal1ty, etc.zenboy wrote:Limiting PSUs to 250, that's a very exciting idea.

Putting limits on those things would pretty much eradicate all those annoying trends I mentioned. Personally, I can live with 6 mhz as long as I don't see another MySpace profile.
well it obviously want fully loaded, since his PSU power consumption never exceeded 350watts. It may have been because of instability in the lines at higher loads though, and switching to a higher output PSU allowed its current load to reside more in the mid range of the new PSU allowing for more stable voltages.burebista wrote:Not quite.

the fact of the matter is it could of been alot of different reasons the new PSU fixed his issue, but it obviously wasnt an inability to ouput enough power.
I have the perfect, zero noise, money saving solution for you. Cancel your internet service. Disabling the onboard nic or removing your card, or god forbid, modem, will probably save you a couple watts electricity too.mantralord wrote:Putting limits on those things would pretty much eradicate all those annoying trends I mentioned.

This course of action will solve _two_ problems.
while i dont subscribe to mantralords list of annoyances we could live without, i do see a real need for limits as far as power consumption goes in PC's.
I dont see any problem with a 200-300w PSU limit
it would force electronic company's to innovate instead of just upping the voltages to allow for more stable clock rates.
Personally though i doubt it would ever happen. The more likely scenareo is that power consumption starts becomming excessive to the point where it begins to bother consumers. Just like whats currently happening with CPU's. People were bothered by their loud computers because they needed such large amounts of airflow to keep their power hunger cpu's cool. So CPU makers are now going towards low power consumption and "power/watt" performance charts. Same thing will eventually happen with video cards, and then there power consumptions too wil come down. Once this all occurrs, you wont NEED power supplies that output anything more than 300watts, because no matter what you put inside your PC it couldnt possibly exceed that limit.

My last few posts are just satirical guys (I know it's not obvious). As Aris suggested, a limit would be beneficial to everyone, though I wouldn't like hard limits on these things. However, I would like to see more common sense out of PSU companies (and people in general).
Maybe, although the corporations will fiercely resist anything that hits their bottom line; it may be easier to educate consumers in something that is really in their own best interests anyway (ie in this instance right-sizing their PSU).It's harder to teach common sense to individuals than it is to corporations...
There's a large gap, philosophically and logistically, between educating consumers, and regulating industry, and that is my only point. I have no problems with the 80 Plus program, something that rewards making sensible ecological decisions, or a similar program that would reward VARs that matched actual system demand to power supply capacity. I do have a problem with punishing someone for catering to a niche market, or regulating them away from it.
Turn the gun around for a minute, what if there was a "minimum noise level" regulation imposed on computer components. It'll be pitched as a safety regulation, to make sure that everyone is aware that that device is electronically active. It'll be pretty quiet by alarm standards, something like 45db beeps every 1500ms. All devices that operate on A/C or DC above 3.75V/500mA have to be equipped with them to prevent shock. Would that make you happy? Likely not. Could it make a crosssection of people happy? Quite possibly (Misinformed luddite over-protective parents, maybe?).

I think also they might be measuring fairly for noise characteristics...unlike our favorite friends silenx. I really wish companies would disclose their actual noise measurement methodology, it's not like the average consumer would look at that anyways.zenboy wrote:Thank you Jeebus.Rusty075 wrote:To drag this thread back, kicking and screaming, on to the topic:

Of course, the X-Fi will be connected to some crappy Logitech speakers, and the mousepad will be one of those ugly Thermaltake light-up ones. And the lighting will be blue. Definetly blue.
