What the hell is a good psu for a SLi-DR expert?

Nothing too excessive in price. the powerstream 520 is slightly over the top. ANything cheaper with pots, 8-pin eps, and 24-pin atx?
 
Seasonic S12 500w... (people have been having problems with em, but if you get one working well, you got a winner)
-Antec Neopower 480w
-Enermax 485w
-Antec Truepower II 550w.
 
you will need an 8 pin connector (keep this in mind) some PSUs come with 2 x 4 pin connectors that can be joined in to form an 8

Enermax is weak. Just compaire the diffreance here in this article

Antec Neopower is a nice concept but a bad idea. Why? Because too much power or voltage is lost through those little plugs/wall jacks. Plus it is not a swiching PSU.

Antec True Power II, another overated PSU from Antec (the Bose of PSU makers). True Power II lacks PFC and other important features.

Antec and Enermax are two of the most overated PSU's on the market. Both of them Get their ratings at lower than room temperatures and do not test them at high temperatures for extended periods of time. PC Power and Cooling is one of the Few that do this and is part of the many reasons why they cost a few bucks more.

My recomendation is a Turbo Cool 510 From PC Power and Cooling.
Turbo Cool 510 is rated for 510watts contious load at 50° C and 650 Watts at 30°C
Enermax is rated for (correct me if I am wrong) 485watts at 25°C, so that is like getting a 300watt PSU rated at 50°C. Oh and those removeable cables they use on some models contribute to even more power loss, that 300 watts drops down again to 250-275 watts.

PC&C is the very best PSU, we can see it from the price, and it does sounds like a vaccum cleaner.
Antec and Enermax maybe overrated, but they cost 1/2 the price of PC&C, and they are of better than average quality and they will work fine w/o frying your pc.

As for the 8pin, I am only aware that the OCZ Powerstream and Seasonic S600 has them.
 
PCP&C is not worth it if you're building a normal, high performance system. I chose the Seasonic 500W for its quietness, efficiency and coolness. And so far, it has performed greatly <crosses fingers>. I say get that. Although, it is about the same price as the OCZ Powerstream 520W, which is a great power supply in its own right.

If you want something less expensive but just as capable, check out the Enermax Whisper 535W. It is SLI cerfitified by nvidia and is awesome.

Worth it? I do not think Enermax, Seasonic, or Antec are really worth it. They are too cheap and all three of them leave out important features and use smaller parts than PC Power and Cooling. Enermax does not even bother to filter the incoming AC current for EMF (Radio Frequencies). That EMF eventually gets passed down in to your motherboard, video card, CPU, RAM, HDD, etc. This can lead to stability and data integrity issues.

Just read this and you may puke at the Enermax then never want to buy any thing less than a Turbo Cool.

Also a good article explaining PFC

Turbo Cool PSU's are not as loud as people say they are. At $200 most have never used or seen one. I have and the small sound coming from the back was not anywhere near as lound as a Vantec tornado. It makes just a little bit but not much more noise than Antec True Power 430.

As for the 8pin Motherboard conection, that is avalable as an option from PC Power and Cooling; just ask for it when you place the order by telephone. Any PSU from them is completely customizeable and any thing is possible just ask the PC Power and Cooling sales representitive.

I do not work for them. I am not a shareholder nor do I have any vested intrest in PC Power and Cooling.

425 Watts (equal to a 525 enermax/antec) should be plenty. Just ask for the 8pin, sli, and SATA connectoins when ordering.

OMG so much FUD! Where do I even start.


Enermax is weak? I can counter your link with a much more reliable (IMO) source.

Antec's Neopower isn't that inefficient as you suggest it to be when it comes to supplying power and how is it not a switching PSU? It draws as much power as a system needs and not anymore, e.g. it doesn't draw 600W AC from a power outlet when a system only requires below 200W DC to operate. In practicality, pretty much all PSUs for the desktop sold today are switching PSUs.

True, the TP-2 doesn't have Active PFC (unless in Europe) but can you find a link (you're good at doing that 😉) that says it has no [Passive] PFC at all? There are PSUs out there that list no PFC feature at all in their marketing material yet still offer Passive PFC. Wouldn't surprise me if the TP-2 has passive PFC.

Antec & Enermax, while I'm not aware @ what temperatures they're tested at. They are however rated for 40 C (Enermax) & 50 C (Antec) operation. This and this states that they are capable of providing their maximum rated wattage under high temps - more than 25 C.

I present this to you. As for EMF, this is a first for me. Who knew radio frequencies from a PSU's components (surrounded by metallic casing) would be powerful enough to do this to a computer system. 😕
