Ignore the 127C and obviously the -ve temps as there are no sensors for this. Just pay attentions to temp1 (your CPU temp) amd temp2 (your Mobo temp).

I bought a very inexpensive "PowerUp" generic 400 watt PSU from TigerDirect.ca.

Three speed fan switch and quite quiet. Also appears solid as a rock.

Maybe I'm just lucky...but this is pretty good.

maybe add L&C to the sh!t list, it came with my case. I can't get past 173 fsb on my oc no matter what i try, im gonna grab a thermaltake silent pure power I think. But roughly how many decibles are the enermax noisetakers?

Ps. If you had the choice, would you take a thermaltake silent pure power, or an enermax noisetaker? more for silence than anything else

Enermax Noisetakers piss all over the Thermaltakes in quietness terms. There's a reason I don't have Thermaltake on my list. The list consists of only THE quietest PSUs out there.

There's a comment in the guide that sums up Thermaltakes quiet boasts:

"Just because a manufacturer has the word quiet in the specs don't belive it! Also ignore manufacturers dBA ratings, even if it is a top brand."

Why on earth would you need that? PSUs become more efficient the closer they get to their max load. If you have a 370W Enermax and use say 300W it will be say (complete guess) 80% efficient which means less heat. A 485W one will run at about 60% efficiency on 300W load (which you arn't even using right now) and will produce more wasted heat.

I think there's one around 430W which is beyond enough.

The Nexus I have is 400W which is till more than enough, it's quieter and probabaly cheaper too.

It pains me to do this but...

I'd like to pull Tagan from the list of good brand PSUs. Their performance and stability combined with that level of quietness is unmatched but there have been far to many reports on reliablility issues. Unit's just seem to fail after a period of time and there's no customer support.

Bye, bye Tagan

So if you don't object Ramman could you do that please? Could we also have Nexus, Seasonic, Fortron Source (FSP) and OCZ added to the list of good brands? Thanks.

I hope that the recommendation of Tagan's in the past in the light of recent reports won't affect peoples confidence in my PSU recommendations.

Oh yeah and I never replied to your Active PFC post, sorry.

Active/Passive Power Factor Correction

Active PFC means the PSU has a circuit to correct the power factor. What this does is improve the efficiency of the PSU. The benifits of which are saving you a little on your electricity bill and it should mean the PSU runs cooler as there is less waste heat generated. It is more expensive to build an Active PFC PSU so these units tend to be more expensive. Remeber though that just like no all PSUs are created equally, not all APFC PSUs are either

Passive PFC means the PSU uses a capacitive filter at the AC input to correct the power factor. Again this imporves efficiency over non-PFC but isn't quite as effective as Active PFC. It also, to a slightly lesser extent, has the same benifits.

Non-PFC - Well all PSUs should have either APFC or PPFC these days, in fact PFC (active or passive) is a REQUIREMENT under European legislation.

This is getting added to my main section

I also think this thread has outgrown it's name. How about just PSU guide? We've covered a little more than just the basics now

Yep, I do believe the basics have been covered and then some. Might be time to do some editing to the new the "Guide". I'll get working on that to try and get it updated this week.

We have a new PSU king of silence! The Seasonic S12. It is quieter than the perevious Seasonics that were already the quiestest around and the range goes right up to 600W now too. It has dual-12V rails like the only previous >400W quiet PSU, the Enermax Niosetaker and is about the most efficient PSU I have ever seen tested

All Hail the King .

Thanks for the info. I'm still evaluating PSUs for my new comp. So I'll take this into consideration.

Question about the Rail Specs:

You mention that the 12 volt rail should have at LEAST 20 Amps on it. However, I am having a hard time finding any PSUs that have that. And that includes on the Seasonic S12 series and the Enermax Noisetaker series. I find it on the Seasonic Super-Tornado series, but not on the S12 series, unless I go over 500W.

Ah but what you have to remeber is both the Noisetaker and the S12 have DUAL 12V rails. Even the 370W Noisetaker has a 13A and a 14A 12V rail. That's effectively like having a 27A 12V rail.

I had a real bad feeling about a water cooled PSU. Water in the PSU, get a leak among the high current diodes and POOOFFFF LOL . Then I read the article, no water in the PSU case, just a transfer block on the HS. Looks very interesting and quiet. A bit pricey though.

I had bought a Tagan, but i sent it back to newegg...it arrived with the warranty sticker broken. I just recently got the Enermax EG495. Back to tagan...I sent an e-mail back in December to tagan considering their power supply(tg-480) and I never got a response until now..May, 10 2005. It took them nearly 5 months to respond to my e-mail. I think that's enough to consider them not worth the effort

Antec Released the Pahntom 500 which is 500W as the name suggests but is semi-actively cooled. Basically the fan kicks on if things get too hot, which is an idea I like.

Looks like it pips the Seasonic S12 in efficiency acrosing to SPCR... they measured it at 90% efficient at 250W and only dipping to 88% at 500W and 78% at a megre 65W.


Antec Phantom 500W efficiency


Seasonic S12 430W efficiency


Antec Phanotm 350W efficiency


For reference Noisetaker 475W

Depends on what other hardware you've got in there and the brand of PSU. If you just have a HDD, RAM, and an optical drive, along with the 6800 you should be OK with Thermaltake or Antec. I would go for a 450 or 480 to be on the safe side and for future upgrades.

Antec's new Neo 430 HE is the first exceptionally quiet modular PSU. Not quite as quiet as an S12 still, but close.
