My 3 best boards are BIOSTAR, ASROCK, and ASUS. Other boards I have used are MSI, FIC, GIGABYTE, and XFX. The MSI ran so hot it would crash and the FIC had a bad BIOS and the replacement BIOS was also bad. The XFX went dead and 2 XFX video cards also went dead. XFX replaced the board and it was DOA. I bought the MSI, FIC GIGABYTE from local vendors, and The ASROCK from an OEM vendor on the Internet. The BIOSTAR I got from Tigerdirect. The ASUS boards I got from Tigerdirect and Newegg. Is the Gigabyte still working? My GTX295 is a BFG and It is now overclocked to 641MHz(gpu), Shaders(1382MHz) and the Ram(1101MHz).

Defective in what way? I´ve heard that they tend to break, but I have several of them, and never experienced any problems. Just curious. |

How's this? http://www.firingsquad.com/news/newsarticle.asp?searchid=20834 Or this? http://www.infoworld.com/d/security-central/lawsuit-claims-nvidia-hid-serious-flaw-in-graphics-chips-439 And here's the Google Search I did on this.

No the GIGABYTE was good board it just became antiquated. It was the second board I used after the FIC in 1999. I still have the ASUS has the Nvidia 680i chip board and the BIOSTAR board has x45 chip. The BIOSTAR board over clocked better than the ASUS board due to the x45 chip. |

But maybe things have changed now, but I avoid them like the plague. I have two ASRock Socket A boards that are still going strong/solid. I had one Socket 478 board die on me, but I blame that on the user letting their machine get too hot in a small, confined room with a Prescott CPU. The only reason why I don't continue to use them is because I like Asus' EZ Flash utility for easy upgrades, especially when you don't have a floppy insstalled in the machine (and you don't own a USB floppy drive either). |

I've been told by Thermaltake that 4 GTX295 cards would not be possible in the US. So I may just stay with a GA-EX58-UD4P motherboard since the 4th slot in the ASRock would just stay empty as Thermaltake said their 1500w psu is only for Europe not the US(I guess We don't have 240vac in their little minds). :(p The T1 Trust, PRR T1 Class 4-4-4-4 #5550, 1 of America's First HST's |

Put 2 PSU in your case. |

Remove the top 230mm fan and replace with 2 thinner 120mm fans(Which I'd have to buy most likely as I have mainly 120x120x38mm 148-150cfm fans), 2. add the 2nd psu and then 3. get a special cable from Coolermaster that links psu #1 good(Green wire) and ground(Black wire) to psu #2 so that when psu number one is turned off or on they both power down or power up.

Only one of them would be connected to the mobo with the 24 pin connector. This would mean only that psu would be connected to Vsense (pin 13) and psuOK (pin 8) The Vsense pin is used to ensure the correct voltages reach the motherboard by canceling any losses in the cables. The psuOK signal is used at boot time to tell the mobo it is OK to switch on and to cause an immediate computer shut down if the psu reports in is NOT OK. Therefore what are the consequences if the second psu supplies the wrong voltages, and what happens if it fails and the computer does not close down. Could there be a release of that all important smoke? |

Available at NewEgg. It is a dedicated Graphic Power Supply. LianLi also makes a double 24-pin connector to enable 2 PSU to be connected to the mobo's 24-pin connector. Toppie. |

I nave not looked at coolermaster's two psu's solution, but paralleling the connections AFAIK is not the complete solution. For the psuOK signal it is fine because if either signal indicates a fault the line will be forced low and cause a shutdown. But for the Vsense line I am dubious. If the psu's 3.3V outputs are different and one is low while the other is high then there is a chance that one of them will be forced out of spec. |

For the psuOK signal it is fine because if either signal indicates a fault the line will be forced low and cause a shutdown. It's like the one below from Frozencpu, It's a $14.99 part from LianLi, Coolermasters version is a 20 pin cable, While LianLi's version is a 24 pin cable. As You can see the 2nd psu never plugs into the motherboard, So I don't see what the problem is, I mean what peripheral device uses 3.3v? And last I looked the pci-e cables don't use anything besides 12v and ground(Yellow=12v and Black=Ground in DC voltages). The T1 Trust, PRR T1 Class 4-4-4-4 #5550, 1 of America's First HST's |

For the psuOK signal it is fine because if either signal indicates a fault the line will be forced low and cause a shutdown. Theoretically SATA drives. But not that many really, but it is the 3.3V line that is monitored remotely to ensure all output voltages are correct. Therefore the question is, is the 12V line of the second psu in spec and how much does it vary under changing loads without the correction line. |

2 PSU in use on 1 machine has been done not by me but by others who have posts on the internet and show and explain how it is done. There are cases made to handle 2 PSU and 1 motherboard. |

And Coolermaster makes some of them, With some reversible mods It could be done to the HAF 932. Besides I may stay at one PC and sell off the extra components.
