Guys,

I've had a machine built for me. Its quite a good spec, but the people who built it for me have not done me justice with the PSU. This is my current PSU:

The double-whammy comes from the fact that its a 20 pin, whereas my mobo is a 24 pin. Still powers the machine though.

The spec of my machine is:

Pentium 4 - Socket 775
(max speed 4000MHz - current speed 3000MHz)
Board: ASUS P5GPL Rev 1.xx
Graphics: NVIDIA GeForce 6600 GT + its own fan.
+ 2 optical drives
1 SATA HDD
1 TV tuner card.

(sarcastic tone) - Somehow i've been experiencing power loss to my machine since i got it.

I didnt know anything about PSU until looking around this forum and reading up (not that i know everything now), so i was quite oblivious as to what was in mine, and didnt link it to power loss. as far as i can make out, there is only 17A on my 12V rail, which im told is the most important for high-end machines??... am i right from reading the sticker on my PSU?

Can anyone recommend a really sweet PSU for my needs? - on a website calculator for wattage, i came in at 380W (with the 30% added) but would prefer higher. the quieter the better really, and i hear that APFC might possibly be good at reducing noise?

anyway chaps, i leave myself at your mercy.

Appreciate any advice you can give me on this one.

Thanks.

Sorry everyone - should have said that i have read the PSU101 advice, found it VERY helpful, but still would like some advice from hardened PSU pros in here (or the next best thing)

Would also like something that supports ATX2.0, Dual12v Rail - (for future builds)

thanks guys.
 
Check out OCZ or PC Power & Cooling. Look for around 480W and 24A on the 12V rail expect to pay at least $100.
 
Thanks for those

ive enountered some issues with the seasonic:
I've just been looking at the Seasonic rage and see that the fan is 120 high, which doesn't fit into the pre-fabricated slot / compartment that my current PSU sits in... its only high / wide enough for the conventional PSU size.

Also, is dual 12V really better, as you get a lower total amps on +12v that way. i hear that dual is more stable...

As johny five so elequently put it: "need more input!"
 
OCZ makes good ones, look at there powerstream line -

Their Modstreams unfortunately are more bling bling than performance tho.

but still would like some advice from hardened PSU pros in here (or the next best thing)

Hehe so im not a seasoned pro ... *cries in corner* :P Anyways, whats the budget?

with dual 12v, the amps are split over both rails, which makes it more stable.

Only if you make use of it ... no point in having dual rails if you're trying to power a videocard + 5 HDDs on one rail and a fans on the other :P
 
Heya

I would recommend Fortron PSUs. I would aim at 500W with two 12V rails for the sake of future usability. The ampage on each of the 12V for the 500W Fortron PSUs are 14 and 15Amps respectively.

JAN :D

yes good point. you want to makes sure you "configure" your power connections right in order to really see the benefits of split rails.
 
Thanks guys. Do you think though that the fan on the Seasonic S12 being on the bottom / top of the unit is better than the conventional approach which is to place the fan inside it and low air out of the back?
