XFX 650i ultra problem!!! no video sign and no beep sound

[jnfirst]

I'm having almost the same problema with two computers using XFX 650i Ultra motherboard.

1) MB + Pentium E4300 + 2GB DDR2 Samsung 800mhz + VGA EVGA 8600GTS 512MB + HD Samsung 750GB SataII 7200rpm + DVDRW Pioneer 111D + PSU Thermaltake 430W W0700
Problem: turns on, send NO video sign and don`t make any beep sound.

2) MB + Pentium E6320 + 2GB DDR2 Samsung 800mhz + VGA XFX 7300GT 256MB + HD Samsung 320GB SataII 7200rpm + DVDRW Pioneer 111D + PSU Satellite 545 400W
Problem: turns on, send NO video sign and SOMETIMES (very rare) makes a long beep ( long beep + stops + lomg beep ...).

I`ve already tested in a friend house the memories, CPUs, VGAs, HDs, DVDRW drivers and PSUs (all working fine!).

Do you guys have any idea about what can be done???

THX!!!

At least for system one, my bet is that your power supply can't supply enough +12V power for the MB+CPU+graphics card (remember, your graphics card takes so much power it requires a separate 6-pin cable from the PS be plugged into it for extra power). This doesn't mean your power supply is broken, just that it can't supply enough +12V power (total watts don't really matter anymore, just the +12V outputs).

Hi, firts of all I thank you for the help!

But, I've already thought that PSU couldn't supply enough power, but now I'm sure that isn't the problem. The facts:

1) Computer number 2 don't requires too much power (XFX 7300GT don't requires extra power, it's power comes just from the the slot);

2) the 8600GTS requires a 04-pin cable, not 6-pin;

3) I've already plugged the XFX 7300GT in the computer number 01, so if it were lack of power supply with 8600GTS, using the 7300GT the computer should work properly;

4) I used the exactly PSU model with my last computer (AMD Athlon64 3500+ Asus sli mobo + EVGA 256MB 7600GS) it used almost or more power than computer number 02 and it worked fine;

5) I've tested my CPU (E4300) + VGA 8600GTS in a friend's computer using PSU Seventeam 420W and it worked fine also (his mobo were an Asus P5ND2 - I think). So my PSU should work too.

have same problem
went googling
found ONE website that mentioned something about this mobo, mainly a short paragraph that can be found at http://www.hothardware.com/printarticle.aspx?articleid=961

The board is built on a standard ATX form factor and will fit in any ATX chassis on the market today. The board requires a 24-pin primary ATX connector and an 8-pin secondary ATX connector to run, so this may mean that upgraders will have to purchase a new PSU. These connectors are typically equipped on dual-processor boards, although with single-chip quad-core CPUs becoming more mainstream, having an 8-pin secondary ATX connector on even budget-level boards is common.

Unfortunately it wasn't my problem. But I've already used my garantee and the new mobos are all right...

Now I'll start overclocking my 4300... lol! Just waiting my TT Big Typhoon
