Need psu recommendation

[ic3m4n2005]

OK guys need quick info :)

I already own a Liberty 620w but i'am going to upgrade my hardware.
Future system will contain quad core and 2 8800 GTS and the rest ...watercooling, few hdds, dvd, but this shouldn't draw so much.

So what i want to know is if a better psu will help me with overclocking or is upgrading already a must or can i stick with this psu? What would you guys choose for about 130-150 €

You can add this:

FSP Group (Fortron Source) BoosterX 3, 300W SLI Graphic Power Supply
Dedicated Multi-GPU Graphic Power Supply Unit
+12V@25A, Not Rated for Temp, EFFICIENCY 85%+, 2yr Warranty
Specs: http://www.fspgroupusa.com/FSPNEWS/BOOSTERX3.asp
From $66: http://froogle.google.com/froogle?sourceid=navclient&rls=HPIC,HPIC:2005-18,HPIC:en&q=FSP+Group+BoosterX+3,+300W&oe=UTF-8&um=1&lmode=online&scoring=p
If you have a good PSU, but need more power for SLI,
just put this +12V (only) GPU PSU in an empty 5.25" bay!

Or upgrade to one of these:

[ic3m4n2005]

I had the Decathlon in mind since it has cable management which i dont want to miss anymore :)
But it's rare and expensive here in germany (168 € + shipping)
Anything less expensive ?
The booster seems to do it but i want to stick with a single psu.

[leopr]

This comment might enrage some ThermalTake haters but i really recommend you any ToughPower ,of course with such high end system you should take the 850W+, the TP series are really cheap compared with other companies and it provides great quality and stability, myself, owning a Galaxy of 1KW bought two TP of 750 and 600W for my brother's PCs, no problems, stable rails, quiet and not hot at all PSU and if i am not mistaken, starting from the 850W series they are certified for Quad-SLI by nVidia.

[Nazu]

Yeah the Toughpower series from TT is good. Jonnyguru tested the 750w model and it was very good.

[ic3m4n2005]

Is it better to go with multiple rails or a strong single rail (60A on Decathlon)?

[cantankerous]

Lately the high amperage single 12v rails seem to be the way to go as cpu/gpu require more power without the need to worry about load balancing. The Decathlon (if you want modular) or the Olympia OP750 seem the way to go.

Is it better to go with multiple rails or a strong single rail (60A on Decathlon)?From EOC PSU Guide: http://forums.extremeoverclocking.com/showthread.php?t=136602 :fact:

As you will see all PSU's recommended for highend systems are Single +12V Rail PSU's.

This has now become necessary for several reasons:

PSU manufactures are now assigning the rails on their multi-rail (3 or more +12V rails) PSU's in whatever fashion pleases them.

Motherboard manufacturers are now requiring additional power connectors, beyond the standard ATX & P4/EPS connectors.

Sometimes the interaction of these unique rail assignments & additional power connectors results in mobo/PSU incompatibility.

All of these problems are of course caused by the ever higher power demands of ever more powerful GPU's.

Most Dual +12V Rail PSU's are not effected as one rail "should always" be used exclusively to power the CPU via the P4/EPS connector, however Dual Rail PSU's that follow the specs can not power highend SLI systems.

Therefore all PSU's recommended for highend systems now need to be Single +12V Rail PSU's.

Please note that the Seasonic built Corsairs & Antecs (HE & Trio) are, regardless of advertising,
Single +12V Rail PSU's, in that there is no per-rail current limiting, meaning that any +12V rail can pull whatever +12V amperage is available. This is also true of the Seasonic M-12's.
The Corsairs are built to higher standards than the Antecs.

8. ARE MULTIPLE 12-VOLT RAILS BETTER THAN A SINGLE 12-VOLT RAIL?

With all the hype about multiple 12-volt rails (ads claim that two rails is better than one, five is better than four, etc.), you’d think it was a better design. Unfortunately, it’s not!

Here are the facts: A large, single 12-volt rail (without a 240VA limit) can transfer 100% of the 12-volt output from the PSU to the computer, while a multi-rail 12-volt design has distribution losses of up to 30% of the power supply’s rating. Those losses occur because power literally gets “trapped” on under-utilized rails. For example, if the 12-volt rail that powers the CPU is rated for 17 amps and the CPU only uses 7A, the remaining 10A is unusable, since it is isolated from the rest of the system.

Since the maximum current from any one 12-volt rail of a multiple-rail PSU is limited to 20 amps (240VA / 12 volts = 20 amps), PCs with high-performance components that draw over 20 amps from the same rail are subject to over-current shutdowns. With power requirements for multiple processors and graphics cards continuing to grow, the multiple-rail design, with its 240VA limit per rail, is basically obsolete.

PC Power and Cooling is once again leading the industry. All of our power supplies now feature a large, single 12-volt rail. The design is favored by major processor and graphics companies, complies with EPS12V specs (the 240VA limit is not a requirement) and is approved by all major safety agencies such as UL and TUV.

From Silverstone: http://www.silverstonetek.com/products-da750.htm

"With the knowledge that single +12V rail power is the next generation power supply, SilverStone Technology introduces Decathlon series, offering enthusiasts more choices with single rail power selections to handle their system."

Go for that one...however, i'll warn u right now, there is no guarantee that your current powersupply WON"T run a quad core and two GTS's, the liberty 620w is one heck of a psu, pls do try it out with the new system before upgrading the psu.

Perkam

[ic3m4n2005]

Personally i think the Liberty will do it, but better invest 50 extra bucks than seeing everything blown up :)
Is there a major difference between the Olympia and the Decathlon ? Since i really really like the modular cables :D

Perky, a QX6700 and 8800 SLI pull a certainly retarded ammount of power.

My rig on air and low voltages can almost stay above 600w during all of 3dmark...

This thing can idle(> 1.5v core ) higher than 1.6v conroe orthos.(430w in my cases)

[thunderstruck!]

I would get the Silverstone OP750W (or whatever it's called). Check out Jonny Guru's review (http://www.jonnyguru.com/review_details.php?id=100).

As for the big Liberty, its +12V is split in to 2 rails with per-rail current limiting,
if it was a single +12V rail, there would be no problem. :(

[WRC]

i wonder if mods can sticky a thread with single rail psu's, kind of like the official quad rail one :) it would be very helpfull

[ic3m4n2005]

3 Shops are listing the Olympia 750W but no one has it on stock, the Decathlon is on stock but i've only seen it in one shop. Another thing is that there are no Zippy or PC P&C psu's on the market here :(
Will wait a few days and see if there is an OP 750 on stock, if not i've to go with the more expensive Decthlon since it's on stock.
Thanks for giving me recommendations to all of you ;)
