PSU for new system?

No offense but Coolermaster PSUs cannot compete with Enermax. I would put them with Antec. Yes, 2 rails are nice, however the point of two rails is diminished if the rails are so horribly weak (10A and 12A).

A MUCH better alternative to the Coolermaster PSU's are the Seasonic PSU's which are superior in every aspect.

How bout the PC power and cooling Silencer 470 ATX it's only $99, it's only issue is no PCI express connector, otherwise looks solid and it's a PC power and cooling unit w/ 5 year warrenty.

Edit it's at PC Power and Cooling Silencer's Page I'd put it up aganist any of the other supplies listed in this thread, also as an FYI it does have a 24pin connector.

WELL Obviously you have done very little study on Coolermaster. Those specs you quote are continuous not peak. Peak 16 and 18 on 12 volt. A fallacy many people make when judging a ps is they look at specs which are quoted for peak power. Peak specs at most are designed to operate for a very short time. In many cases less than 1 minute. The Coolermaster has a peak output over 550 watts. But the RS450 is the only "true" 450 watt ps on the market. It is also the only one on the market which has been tested up to 400,000 hrs MTBF. Its voltage regulation is within 2%. Look at how well it performed in the SPCR review. And here is one many folks overlook. The specs Coolermaster quotes is for operating temperatures up to 40 degrees celcius. Enermax and Seasonic quotes their specs at only 25 degrees celcius. Seasonic ps's are good but certainly not superior in every aspect and also for the price they charge don't offer a difference great enough IMHO to warrant the higher asking price.

PS: I don't usually like to pimp one product or one brand. But I have like many others have over the years bought and used a lot of pc hardware. When I come across what I believe is an outstanding piece of hardware I do like in this case, want to point out how good of product it is.

The Cooler Master RS-450-ACLY looks very impressive. The only thing I couldn't find was what its warranty was. I went with a OCZ model, but I strongly considered the Tagan Series unit before buying. I think this unit would have been a good purchase as well.

Their website is not working for me, but if it had a three year warranty, this would be a great choice.


 
No:

Seasonic and Enermax take temps at 40C. The regular non Whisper, non Noisetaker enermax's are taken at 25C.

The RS450 is not the only "true" 450Watt PSU on the market. There are plenty of good 450Watt PSU's on the market (OCZ Modstream is WAY better). I HIGHLY doubt its peak output is >than 550. In fact i would put its 60sec peak output around 530.

I have not made a fallacy when judging the PSU. Most PSUs (Quality that is) are quoted by their sustained/continuous specs. This PSU is not powerful enough to handle a significant load. This is one of the cases where a single 12V rail would have been more prudent. Splitting it up like this into 2 very weak rails was not a good idea. That would be hardpressed to handle any significant load.

Seasonic PSU's ARE superior in every aspect. Where are they not... you tell me.

Its 3 years for the Coolermaster. But OCZ is good too. Not as efficient as the Coolermaster though. Tagan seems to be either liked or disliked around the net.

Seasonic is at 25 Degrees C. Look here its going to open up to the pdf, takes a couple of seconds and this is for their latest model. S12 Pdf
I did look up Noisetaker again and your correct, my fault.

Dude can you read? The Coolermaster has 18 and 16 on the 12 volt rails. But Coolermaster quotes the true sustained power on a continuos basis. None of the other PSU makers do that. Also on the Seasonic go to the Egg and compare the specs for the RS450 and Seasonic 500. The RS450 is almost half the price with better specs. Give me a break. Seasonic's are high quality, but also highly overpriced. And again the question is quality vs price. With the Coolermaster you get the quality, performance equal to or superior to others, and a good price. To say the Coolermaster is not an excellent alternative to this poster's question is foolish. And let me also add, I have yet to hear any complaints about this ps on the net and it has recieved a favorable review by every single site that has reviewed it.
 
Im voting on the OCZ 520, very very nice and quiet--only bad thing I can say about it is the green leds dont match the blue on the rest of my fans.

And both of you have to have a potty mouth what is your point. It takes two to argue so you cannot pin the blame on one or the other.

Aspire PSU's are known to be in the same league as thermaltake. They are flashy and good for light load and light OCing. Although they may look cool (tacky in some peoples opinion) thats the truth. Tagans on the other hand are very nice PSU's. They are very quiet and are rock solid. Maybe not in the same league as OCZ or PCP&C but definitely very good for the money. To bring this argument back OT just get a quality PSU. I would, for a system of that caliber reccommend the OCZ's, and PCP&C. If you do not want to spend that much, take a good look at the Enermax Noisetakers, the Seasonic S12 or Super Tornados, a decent Tagan, or a sparkly/fortron. I find it hard recommending Antec as i said earlier because they are specced for last gen hardware (hence the reason Antec is releasing the TruePower2.0).

Tagan fell short in the Tom's Hardware review posted today. They were weak under mid to heavy loads. We are editing the posts, cooler heads have prevailed.
