Re: Power on & then quickly off

[ValleyArts]

I'm having the same problem, the system won't turn on until I've disconnected the 4-pin-connector (and naturally it won't show anything then either because the processor (?) doesn't get any power). I'm using a thermaltake 550W power and the system worked for a few hours before this happened. I will retry with an antec power as soon as I get my hands on it...

(And yes I realize that 14-15A@12V is not adequate. More than 18A is recommended I read.)

# Core i7 920 cpu 2,6GHz
# X58 Platinum Pro
# 6x2 GB Corsair Value 1600MHz
# MSI Radeon 4870 1GB PCI-E
# 2,5" Hitachi 5400 80 GB SATA150
# Windows 7 RC
# Thermaltake 550W, 14-15A @ 12V

System with 4870 minimum recommended PSU, +12V~32A, single +12V rail. Ignore watt rating as it is not a reliable method to determine adequate power.
Antec, Cooler Master, Thermaltake are poor choices. Single +12V rail Corsair VX & TX series & PC Power & Cooling PSU's are the top recommended choices.

ValleyArts, I'm splitting this post, in the future start your own thread even if your problem is similar to someone elses.

Hi ValleyArts, & welcome to the forum.   Not 'all' Thermaltakes are 'less than desired' anymore. The new XT 650, 750, & 850 models are 'all' single +12V rails.

Hi, and thanks a bunch for the replies.

The Antec power I'm going to try has two rails with 22A on each. So in theory the processor and mainboard could run on one (18A) rail and the graphics + harddrive/other peripherals could run on the other rail (~15A). Is there also any way to see what cord goes on which rail (I.e. 4 molex connectors with 2 on rail 1 and 2 on rail 2) or is one of the rails always dedicated to the processor and perhaps the mainboard?

This also gets me confused about single rail power supplies

Any comments are appreciated.

Yes. Go to the manufacturers website, & look at the tech. spec manual for the PSU you are considering.

Hi, it seems I've managed to short-circuit the mainboard with conductive ink (yes, testing the mainboard on an anti-static bag is not a good idea, next time I'll use some insulating layer.) so it need repairs. My stupid mistake and I'm sorry for that. The system works fine with a Pro-E mainboard using the Antec Earthwatts 500 power supply:

Ouch! Time consuming & costly mistake. A non printed piece of cardboard, non slick/shiny stack of newspapers, or a natural surface wood slab will work pretty well for testing on. Hope everything works out fine once you get your board back.
