do you have 10 hard drives and a dual CPU to need 550 watts?
its kind of overkill dont you think?

anyways that PSU has nice cabling, and they did not use those ugly Tt orange fans by the looks of things.
 
No, I don't have 10 drives. But I'm tired of purchasing psu's, now I'm gonna get me one that lasts for some time.
And I might get a Vapochill later on, and that drags alot of power, and I also have loads of fans and stuff connected.

With the new form factor coming out this year you'll have to buy a new PSU for the new cases and motherboards when they switch to BTX form.

400w is plenty for most any system. I would get a seperate PSU for running vapochill or cooling off of. Antec and Fortron are about the best and usually the only two that i use in builds. I recommend the Antec True Power 430w.

Really? A new standard? Can't say I've heard about that. When is this suppose to happen?
 
BTX is supposed to start trickling in around late spring or early summer I think, when all the new stuff comes out (Intel land grid array socket, for the most part I guess).

If you buy ATX PSUs, don't be buying them in hopes of reusing it for 5+ years. Burningrave's suggestion is good, go Antec True 430.

Speaking of BTX trickling in, there are some pics of Lian Li BTX cases w/ casters n' stuff in the cool cases section.:)

EDIT: http://www.hardforum.com/showthread.php?s=&threadid=732325 So yeah, you might want to wait for all the new goodies this year.
 
Hmm... Interesting. What will the main differences be between ATX and BTX?
Anyway, I think I might go for a MIST 550W Black http://www.microplex.no/rubweb/prodpages/mistxxxadp/psu.jpg

They say it's only a Antec truepower in disguise, and the specs are just the same.
The price difference between the 430w and the 550w one is so small that I'll just fork out for the biggest.
 
Dude you dont need a 550w PSU lol. And who says its just an Antec true power in disguise? The PSU can make or break every component in your PC so you dont wanna go cheap. Undervoltage and Overvoltage is a serious issue. Wattage rating means nothing. You have to look at the individual rails and see how much can be on each rail at any given time. If its a 600w PSU and only allows 150w on the 3.3v and 5v line combined then the fact its 600w means nothing. Dont look at the wattage rating on a PSU. Its marketing hype that they can sell to noobs with. You have to learn to look at the combined rails and the efficiency rating. If the efficiency rating is much below 70% then the PSU is crap. Just listen to us and buy the Antec 430 or Fortron 400w! lol

I'm running a workstation on an Antec 430w with 6 hard drives. And the systems i build for other people i rarely use larger then a 350w PSU. The only time i consider the need for more then a 400w PSU is when you have dual processors and lots of hard drives.
 
It isn't cheap, but it's cheaper than the one I originally planned to buy. That one is about $140. Of course I checked the amps on the rails, and it's exactly the same as the Antec has.
It's the shop that sells it that says its an Antec, just in a new cover.
Sure, I probably won't need a 550w one, but still, the the price difference is so small, so I really don't care. :D
 
When you said $140, I thought you meant USD, in which case that and the Antec aren't very closely priced at all. Then I noticed that you're in Norway. :D

However, I've never heard of Microplex PSUs. Do you mean it's the Antec Tru550 in disguise? If so, I have no idea how they can offer it for around the same price as the Tru430.
 
Ar bummer, stupid stupid me! :eek:
It isn't a Antec in disguise, its a Forton/source in disguise, I'm terribly sorry guys, but thats what happens when you can't sleep at night :eek:
That kinda explains things, doesn't it? :p
Buut anyway, I've heard nothing but good things about Forton, so this may just be a good purchase anyway. I've talked to people who are really happy with it...
Oh, and Microplex is just the name of the store which sells it ;)
 
I'd say the Antec True Power 380 Watt would be plenty for your system, atleast the one in your sig
 
All the information i've read says the opposite of that. MaximumPC just did a review on BTX in january and said that BTX will require a NEW power supply with a 24-pin connector. As opposed to the current 20-pin ATX power supplies.

And why would anyone wanna try and use an ATX power supply in a new BTX case anyways :confused:.

Ok, while looking around on google, I found this:
http://www.overclockers.com/tips1137/index.asp

This shows clearly that yes, BTX PSU requirements will be an EPS12V compatable supply (Whew, now I'm glad I got a Vantec Stealth 520 :D :D :D)

Did you read everything that was required to turn that ATX PSU into a BTX PSU lol? It didn't just say it will plug into a BTX motherboard and be compatible. You have to do a full psu modding project on the thing lol.

PSU's aren't that expensive so going to the trouble to mod an ATX PSU just isn't worth it when there will be new and better PSU's coming out.

Exactly. And that's another reason it's stupid to buy 550 watt PSUs for systems that need a MAXIMUM of 400 watts.
 
dude Duffman, listen to the ppl on this forum
if they say 550w is overkill, its overkill
and since ur gonna upgrade eventually, i would recommend a nice quality PSU for a good price Fortron Source ;)

Most desktops will never use over 300-350w even if they have three or four hard drives. Its best to go a little larger though like 400-450w so that the PSU doesn't have to work as hard. If your efficiency rating isn't close to 70% then the PSU is crap. Wattage rating doesn't really mean what the PSU is capable of. Its just a number stamped onto the PSU so that noobs will buy it thinking they are getting a large power supply. The combined rails may be less on a 550w psu than on most 400w PSU's.

I can't stress enough how important the efficiency rating is. You can make up the cost of the power supply in no time by saving on the electricity bill.
 
With a PSU there is the Input and Output power. The Input is the power the PSU draws from the outlet on your wall and the Output is the actual amount of power that is usable for your system. A PSU will always draw more power then it will actually output because alot of it is wasted as heat. For example say your PSU is rated for 400w. More then likely the input is around 600w or something. 200w is completely wasted as heat. The higher the efficiency rating, the less power is wasted which means your PSU wont need to draw as much power from the outlet in order to put out whats required of it.

Vantec Stealth PSU come with 24Pin connector...i had to used a 24pin-20pin adapter to plug mine in...does this mean it's a BTX compatable PSU? :confused:

They come with a 24-pin connector? Hmm i didn't know that. Why do they come with 24-pin connectors?

Is the pin layout the same for the 24-pin ATX as the new 24-pin BTX? It would have to be in order for it to work.
 
i have no idea why they have a 24 pin connector...i thought it was a server thing or something :confused:

look here and you will see the adapter i'm talking about, and you can see how the connector is bigger than other PSUs.
 
Some high performance server motherboards require these special 24-pin power supplies instead of the common 20-pin ATX power supply. Make sure that you have a 24-pin motherboard before purchasing one of these power supplies.

What is EPS12V? EPS12V is a special, non-ATX standard adopted by the Server System Infrastructure (SSI) group to provide a more powerful and stable environment for critical server-based systems and applications. EPS12V equipment is not compatible with standard ATX or ATX12V PCs found in homes and offices. Power supplies built to the EPS12V standard include a 24-pin motherboard power connector and an 8-pin +12V connector. (Source: Antec)

I guess thats it right there :).
 
I read in my book that "some" of the new ATX12V power supplies aren't backwards compatible with AMD motherboards, or there 3.3V rails aren't as good or something. Do you know if this is true?
 
ok kids.. you really don't have to worry about BTX for awhile.. It won't be the defacto standard until atleast late next year.... ATX will be around this year, and well into next year.. Intel came out and said that BTX will not be pushed as hard as they'd like this year, and it will be pushed next year...

So, don't worry about that yet... just get a good ATX psu, and you'll be fine..

Personally, I recommend PC Power and Cooling, but that's just me.. the Zalman Noisless PSU's are pretty nice, and aren't that expensive...
 
I am getting the antec true power 380 watt, and it's efficiency rating is 68%. Thats good right?
 
The TruePower series are all very good; their efficiency is around 70% I believe (all of them).

I have a True430, and I think Burningrave uses the same one too (as well as others on this board).

Its rated for >68% so its good. Another good point about the True Powers is that they dont have a combined 3.3v and 5v line.

I use the Antec True Power 430w in my new system and its great. It supports a total of 410w at any given time. The actual output for a PSU is almost always 20w less then its rating. But other PSU's have a combined 3.3v and 5v line so you have to find out how much output they will allow on those two lines at the same time. Usually its far less then what each rail is rated for.

Do you own one? Are you sitting and looking at one ATM? NO? Ok, well then STFU and stop giving wrong answers! :mad:

The Vantec Stealth line has both 4 and 8 pin 12v supplimental connectors, 6 pin AUX connector, and 24-pin EPS connector.
 
so efficiency is only really important in terms of power consumption?

Also, how many watts does the antec true power 380 have on each of it's lines (3.3V, 5V, 12V)?

I've always wanted to understand PSU's more deeply, and now I'm starting to.

Thanks
