Eva, have you gotten SLI to work yet without lockups? I think it may be the drivers.

yeah it was the drivers, did fresh winxp pro sp2 install and 71.89WHL and no more lock ups :)
also PC and Power 510W SLI vs Silverstone 650W review at http://www.linuxhardware.org/article...46&mode=thread
so maybe smartguardian is buggy and my multimeter seems to be low on battery power heh
Awesome bro, glad to hear it wasnt the PSU. Good review btw, thanks for the link.
Ok silverstone replied to my email and here's what they had to say. Im firing off a reply however as i feel the 3.3 rail SHOULD be adjustable just like PPC&C AND OCZ.. There are obvious reasons for these adjustments...
Hi Kevin, thank you very much for purchasing a SilverStone and for sharing your experience with us. However, I must tell you that we do not recommend users to adjust the VR as they are for final tuning before they are packaged and shipped from the factory. Therefore, we do not include instruction on what they do. However, for your information, the +3.3V rail is not adjustable in the ST65ZF. The +3.3V rail is the one that usually requires no fine tuning so the design did not incorporate POTS for it.
We treated your report as a precaution that perhaps our latest shipment had unusually low +3.3V rail. Please keep in mind that our spec calls for a 5% tolerance for all rails so for the +3.3V rail, this gives us a range of 3.14 and 3.47. While the numbers you have measured were still within this acceptable range, we usually like to be as close to 3.3 as possible so I had commissioned our PSU engineer to double check the power supplies we have on hand. And from our testing, we’ve found that all ST65ZF samples we had that were produced recently are still within 3.25 to 3.37 when the load on the +3.3V rail is around 10amp.
May I ask how you are measuring the +3.3V rail with the multi meter? We recommend you measure this value from the side of motherboard 24pin connector with 2 orange wires.
In the rare incidence that the multi meter may not be accurate, the best way to really know if your power supply is not supplying enough power is to use it with your system. A power supply that is not supplying correctly will result in an unstable system. Have you actually tried overclocking your system and see if it had overclocked less than your previous power supply or when compared to OCZ and PC Power & Cooling power supplies you were talking about?
Sometimes it is more difficult to appreciate power supply of ST65ZF’s caliber because very few PC’s currently (if any) can actually fully load it. If you were to get a dual Opteron motherboard with 6800 ultra in SLI and load it up with 4GB of RAM and 10 high speed hard drives, you will then see the difference between ST65ZF the likes of OCZ and Thermaltake. The strength of ST65ZF comes from its high output +12V rails, which is the most important rail for modern high end CPU and video cards. Consequently, this is also where you will extract the most performance from an overclocked system as well. So please give your power supply a try and see how high you can overclock!
If you have anymore concerns or questions, please feel free to let me know.

I can think of 20 people here that could fully load that psu to full capacity, if not beyond. We will see what they say when i fire off my reply.
thanks for the info so 3.2+ on 3.3v is normal to them
Ya, i got another email from them tonight and theyh show me pics of it on the bench. Ill send them over to this computer from the network and post them with their response. He did mention, they are listening to our suggestions.
