[b]saphalline[/b] My proposed PSU

[ErnieK]

saphalline or anyone else
The attached file shows the specs of my proposed PSU. (The one that comes fitted to my new case (The maufacturer and model of it is E Tech MPT-460P))

Will this do the job? New build specs and prospective uses can be seen here. (The maufacturer and model of it is E Tech MPT-460P)

Also to enable me to paste the file into the thread I had to use Firefox as Opera (8) would not open the link for attaching files up. Why is this? Something wrong with Opera 8 or what?

[ErnieK]

Anyone got any Comments? Will this sufice for new system as indicated in thread above?

Ernie, gee I thought that would have been answered really quick. Yes, 460W will be fine for that configuration. You should have power to spare. My new build has a wee bit more inside than yours and I only have a slightly larger PSU.

[ErnieK]

Thanks PopPop
I hope everyone realises that I now have an inferiority complex because naebody wis talkin tae me :p

I even had a quick snuffle at under ma oxters tae see if I had BO - but I huvnae! :rolleyes:

Remember this post (http://www.pcguide.com/vb/showpost.php?p=230033&postcount=15)? The specs on that PSU only give info on one 12V rail. Which means it's not an ATX 2.0 PSU and doesn't have the 24 pin connector. The PSU may work, but it's not what the manufacturer calls for.

[pop pop]

I'll defer to pentachris because I'm not a PSU expert. However, on my current build, the mobo (Asus) called for a 24 pin and 4 pin also. However, my PSU had a 20 and a 4. I hooked it up and it worked...for now :eek:

Neither am I. But I did stay at a Holiday Inn Express last night... :rolleyes: :D

The PSU has the small 4 pin attachment as shown in fig3 on this link. Note the extra 4 pin extender on the end giving 24 pins

What do you mean by RAIL?

[pentachris]

What do you mean by RAIL?
I know what it means; let's see if I can explain it...

A power supply takes alternating current and transforms it into direct current at three different voltages (3.3V, 5V & 12V). Your computer and peripherals have a "well" of current to draw from at each of these voltages, and each "well" is called a "rail."

The new ATX12V 2.0 power supplies produce two separate 12V rails. The specs on these new power supplies that I've seen have two 12V listings instead of just one.

Though your power supply only has one 12V listing on the label, it has the 24 pin ATX connector plus the 4 pin 12V connector, so it looks like you're good to go!

[Fruss Tray Ted]

That psu does have 2-12 volt rails. One is positive +30 amp and the other is negative -0.8 amp.

If a psu has 2-12 volt positive rails then in essence it is a dual supply. I've yet to see one like that. What would be the point if just one with enough amperage would suffice?

most psu's have more than one set of wires coming from the frame but are connected to the same 'leg' or 'rail' anyway. It just saves on the need for larger guage wires that would otherwise be needed to handle all the current.

Yet again you have explained clearly and concicely exactly what you mean. So much so that I actually understand it. :)

FTT
Thanks for the confirmation.

Now for the connecting it all together when the time comes.

I have had to return the case due to a cable having the plastic sheilding split and bare wire showing through. So I am waiting for re-delivery of it. I coud have fitted it myself and then returned the bad cable but no, the company insisted I send the complete case (by insured international parcel post) back to France. What a waste of their money and my time. Oh Well! Anticipation is a lovely thing to live with when it is something good to wait for. ;)

Look here (http://www.antec.com/us/productDetails.php?ProdID=26400) to see one (the model I use); click on the Specifications link to see the two separate 12V rails.

The point is that with two separate 12V rails, if the CPU suddenly starts drawing a lot of 12V current there won't be a dip in the 12V current going to the mobo and peripherals.

ErnieK: I wonder if yours is in fact a "true" ATX 2.0 power supply and not an ATX 1.3 power supply with a modified ATX connector? How to tell? :confused:

It's certainly got plenty on the 12V rail, so I would go ahead and use it. You've spent enough money already! :eek: :)

[ErnieK]

Ok I will go ahead and use it.
But is there any way to know for definate as to whether it is a "true" ATX 2.0 power supply and not an ATX 1.3 power supply with a modified ATX connector??

As you say I have spent way too much money already, but what the heck!
If I don't spend what I don't have how will I justify spending what I do have whenever I finally manage to have something? :confused:

I do have one other problem now though. I am thinking about going the whole hogg and getting a recon TFT (15" or 17"), and as I do not play games it would be a benifit in space saving. Plus it would look a lot smarter sitting there doing nothing (as per usual). Can anyone give two good excuses to get one and 10 good reasons not to get one.
(You are now seeing justification in action :rolleyes: )

Moderators How about putting a smilie up of an ostrich hiding its head in the sand. I need one at this point in time.

[Fruss Tray Ted]

Thanks PC,

And to think I might have made it through a day without learning anything... :rolleyes: ;)

Like I said, how to tell?

Perhaps with a voltmeter and/or oscilloscope (and more knowledge of how to use them than I have :o).

[Fruss Tray Ted]

Obviously by your picture, the psu is NOT a type 2 atx

See here (http://www.enermax.com.tw/products_page.php?Tid=1&gon=261&Gid=18&Gid2=45) for a type 2. Read down in the description where 2 separate +12 volt rails are listed.

Then see here (http://www.enermax.com.tw/products_page.php?Tid=1&gon=249&Gid=18&Gid2=22) for a type 1.3 as listed and also look at the description where only one positive 12 volt rail is mentioned.

Ostrich is a double of myself

[ErnieK]

I ma now going to look at both links. Not that I will be any wiser.

Safe to use existing one? or buy another one?
