PSU Guide

I guess you could try it. On the surface it would meet my requirements for the rig you got.

If you overpower a rail, it shouldn't want to turn on or turn off on high load so just hook it up w/e way you feel most comfortable and go from there.

Well we'll see once I get both my cards.
One is being shipped from Canada and the other one is in a RMA process.
Using a 3450 atm

If you look at my specs, I would comfortably run another HD4850 or even an HD4870 XOC on it in crossfire and its just 550W. ;-)

really? i think u might hav problems, unless the phantom is much more power efficient than the q9400

* Seasonic (usually the most expensive Psu's are seasonics, seasonic also sells their own PSu's, but many times its better to get a rebaged seasonic instead). common brands that use Seasonic: PC Power & Cooling, Corsair,etc.

Its the highest quality manufacturer in the world at the moment. If it says 550W it will do 550W minimum. My Seasonic built EA380 was rated at 380W but I had it pushing 420W for 3 days and it just got a little warm. I should update my specs a bit... lol.

fair enough, i just though "comfortably" was a bit much

I think there is 19a for PCI-E 1 19a PCI-E 2 19a hdds/accs(molexs,SATA,etc) 19a CPU/mobo

not sure if that is right or not its just a guess.I would like to know how my PSU divided the rails also.(I have 4 of them)

Thats what I'm thinking too. Why can't other manufacturers do, what Fractal is doing, clearly labeling the connectors on the psu, as to which use which rails.

Like this (the third picture)

i disagree. it all depends on how the psu is made, in theory if you try and draw more than the amperage on ether rails it should shut down.
anyway, i would recommend single 12v rail psu over multiple rail psu because,independent 12s power supplies are virtually impossible to find so you ether;
buy a psu with a single INTERNAL 12v rail and multiple EXTERNAL 12v rails with there own current limiters.
or
get a single internal 12v and single external 12v rail with current limiter on that rail.

the single rail option is therefore more flexible but the multiple rail MIGHT give a cleaner out put.

Most multi rail psus are made so that it's very difficult to trip the OCP with modern components if the PSU meets your overall power requirements. The high quality manufacturers all split their rails sensibly. Multi or single does not matter. Both have their Pros and Cons, and one should not choose a psu based solely on the number of rails. Even Jonny Guru himself says it doesn't matter at all. All that matters is the quality and output capabilities of the unit.

I know my PCI-E connectors say what rail they are on and i think the 12v wires have a different color stripe depending on the rail its on.If i wouldn't have redid my WM a few days ago i would look but don't want to spend hours again.(this Antec 300 is a bitch for WM)

I have a question: Can you use a separate PSU (like 400W+) to power 2xGTX260 SLI, without connecting the PSU to mobo?!

If you bridge the 24pin connector, yes, of course. Connect a green and a black wire, like this

It works, there are also adapters which are less ghetto like this:

There are PSUs that are only for GPU's, but i dont see much of a point in them as you can just get a beefy standard one to power everything.


If you are saying can you use a standard 400w PSU that you have to power your GPUs, well sure, but you need the space for it, plus they will both use alot of electrical power.

 

[stefanels]

It's NOT for me, a friend ask me if it's possible... I think he have an 550W PSU in the rig and an unused 470W PSU... So practically it's better to sell them both and buy a more powerful PSU like 750W+... NO?

Yes, for space, convenience and power reasons.

thanks for the quick answers...

Ultra X3 Modular 850 watts

This PSU has decent ratings.Any thoughts on "Ultra Power Supplies".

Not the best brand but i dont think there that bad, You can still get a way better PSU.

Thats how a PSU should be built.... AND.. my midtower supports that PSU type.. ;-p

hey guys, panchoman here,

I need some people to help me out with completing the guide. If anyone wishes to help out, please pm me.

-thanks.

I bought a PC Power and Cooling (OCZ) 750 Watt Blue Quad PSu and I've never been happier using a computer!!

thats good to hear... I am still happy with my 700w OCZ and 650w Silverstone both still running strong and taking my abuse about a year later

Has anyone got a TAGAN TG600-U88 BZ PIPEROCK SERIES 600W

I am getting:

INTEL I7 860 2.80 GHz socket 1156
GIGABYTE GA-P55-UD3R this is the motherboard
G.SKILL F3-16000CL9D-4GBGT1 4GB (2X2GB) DDR3 PC3-16000 2000MHZ GT1 SERIES DUAL CHANNEL KIT
MSI 4890 CYCLONE 1GB
SEAGATE BARRACUDA LP ST31000520AS 1TB SATA2
MICROSOFT WINDOWS 7 ULTIMATE 64-BIT
SAMSUNG SYNCMASTER P2350 23'' TFT MONITOR

and I am think of get this PSU would it be ok to use in a few months for a crossfire of 2 of the 4890's?

or would it just be better to get a CORSAIR CMPSU-550VX 550W or THERMALTAKE W0306 EVO BLUE 550W?

Eeeeh I'd be careful with crossfire 4890s and 600W PSUs. I'd get at least a 750W.
