New P6T
Hi,
I installed a new system with motherboard Asus P6T. But when I turn on the PC, all the fans run, HD start, but nothing on the screen and no beep, no keyboard, nothing else. I have a 525W PSU. In the doc, it recommends a 600W PSU. The problem then would it ? Thank you in advance for your assistance. Fabien |

And just how good is this 525W PSU, meaning just how was it rated, i.e., max power, continuous power, etc.? If this PSU is a "typical", plain one, not only is it underpowered by Asus's recomendation, the PSU might not be suitable for a high-end motherboard based on the Intel X58 chipset, i7 (LGA1366) CPU and triple-channel DDR3 RAM. Second thought. How good is the RAM and how much installed? |

Fabien It's improbable that you could come up with a truly functional system configuration based on that motherboard that will run reliably - if at all - with a "525W" power supply - whether that's peak @25C or continuous @80C. Still, that may *not* be the source of the problem you're seeing right now. In the same situation, I'd remove all but the absolute minimum hardware needed to get to the bios utility. Processor with cooler, a single dimm (in the right slot!), no option cards save for a single graphics card, and no drives of any kind (mag, optical, ssd - whatever, disconnect them all). If you still can't get to the bios herald, it *may* still be a power capacity problem, but it might be the motherboard mounting (for instance) or something else (memory in wrong slot, processor improperly installed in its socket, graphics card not seated properly - or something is outright defective). Good luck... /daytripper |

Second thought. How good is the RAM and how much installed? Hi, 3 x 2048. 6 GB. Kingston HyperX. Fabien There are *two* power cables on the motherboard. The 2x4 connector provides 12V to the processor area of the motherboard. If your power supply has a 2x2 connector, that will work fine. If you look at the 2x4 connector, there may be a "cap" covering four of the holes. You would place the 2x2 connector in the remaining holes. If the "cap" is not present, notice the position of the "latch" on the 2x4. The "latch" is towards the end, where a 2x2 could be inserted. http://www.playtool.com/pages/psuconnectors/4pinin8.jpg The picture in the user manual, shows which side is +12V. On the cable and connector coming from the power supply, the yellow colored wires are +12V, so you can verify the yellow colored wire is going to the side of the connector that is for +12V. Your motherboard has a 24 pin main power connector. You can use a 20 pin power supply or a 24 pin power supply. This picture, shows how you would connect a 20 pin supply. The latch on the connector, should still engage. http://www.playtool.com/pages/psuconnectors/20in24.jpg Once the power cables are in place, you can do one test with all RAM removed and with the video card removed. You should hear error beeps, with that hardware missing. The error beeps tell you the processor is reading BIOS code, which is a good sign. If the board remains silent, it could be the processor or the motherboard has a problem. Considering the high contact count (1366) of the processor socket, at that point, I would remove the processor from the socket, and visually check the contacts in the socket. When some motherboards are shipped, there can be crushed pins in there, and they will reflect the light differently than the rest of the pins. Normally, a cap covers the contacts in the LGA1366 socket, to prevent damage. Return the P6T to your seller, if it looks like the socket arrived damaged. If the "no RAM and no video" case, gave you some beeps from the speaker, you can put the RAM and the video card back, and continue with your testing. I think your power supply is fine - the system doesn't draw maximum power, when the BIOS starts up. That comes later. HTH, Paul |
