Yes more details please, what brand is the PSU?

Are you sure all power conenctors are properly connected? Is the power on switch properly connected? What happen exactly, just nothing at all or do the fans spin up?

Has the PC run in that exact configuration (with the old PSU) rund fine before?

The old PSU might also have killed your RAM when it died which would cause this.

PSU is "Storm" 800W

Re: HELP! Brand new GA-EP45-DS3P won't boot

Mobo has 8-pin for the CPU power... but the PSU only has a 4-pin

Yep. Exact same configuration. PC run with a 500w PSU for about a week, then the PSU blew, got anotherone (800w) the next day.

The CPU is a 2 Quad Core 9300

No beeps. Motherboad lights power button, CMOS button and Reset button.

Then I've got a red light on the ACPI LED

...that's about it.

Try just one ram stick at a time. 4 Pin on the motherboard is no problem.

What brand is the PSU (or is storm the brand?)? Sounds like a no name PSU to me, and those are often an issue, and never live up to their ridiculous wattage claims. Many can not even produce stable voltages at a fracture of their claimed voltages.

Done that. Same. No change.

LOL! Yeah, "Storm" is supposed to be the brand. Can't even find anyhting about it on the net either... so you're right "no name PSU".

So... if its an 800 or not I don't care at this point, I just want to figure out if the motherboard fried, or worst the CPU, or what!

What about EZ cool, is that better?

Never heard of it, not a good sign.

Good brands are (from the top of my head, among others): Corsair, Enermax, Seasonic, PC Power & Cooling, Be Quiet!.

If you're not using SLI or Crossfire and no Dual GPU video card then this one is good:
Newegg.com - CORSAIR CMPSU-400CX 400W ATX12V V2.2 80 PLUS Certified Compatible with Core i7 Power Supply - Power Supplies

I hear you...

Thing is, I don't see the point of getting yet another PSU if the motherbee, is RIP.

My problem is almost exactly the same as this guy's (that I'm reading from another forum...)
... he says...:

"new Gigabyte GA-EP45-DS3P

The power switch, the CMOS reset switch and the reset switch, on the motherboard itself, all had their LED's shining. There are a number of diagnostic leds on the motherboard, and the ACPI LED for S4/5 was burning red.
Then I pushed the power switch at the front of the case. The case fans started to turn, for 1-2 sec, the red ACPI led for S4/5 disappeared, the ACPI Led for S0 became green for 1-2sec, the 1st of the phase LED's also became green for 1-2 seconds, the fan in the power supply turned for 1-2sec, the fan on the video card turned for 1-2sec. And then everything stopped again.

I first checked the 24pin main connector and the 8pin 12V connector, reseated them, and tried again. The result was the same, everything turns for 1-2sec, and then all stops.

I then checked if I had connected the power switch cable, HDD led cable, ..etc properly, reseated it all, and tried again. No luck. After 1-2sec everything stops.
I then removed all these cables and used the power switch that is directly on the motherboard. Again, after 1-2sec it all stops.

I now decided to disconnect the dvd devices, and tried again. No luck.
I then disconnected all HDD's. and tried again. No difference.
I reseated the memory sticks and tried again. No difference. I then tried with one stick, then the other stick, then switched the sticks. All the same: after 1-2secs it all stops.

I removed the video card and tried. No luck. The same result again.
The same for the keyboard, the mouse.
I also checked that at the backpanel nothing was sticking into any of the ports.

I tried resetting the cmos, but it made no difference."

That pretty much sums up what I did too.

Well the problem is that you won't know whether it is the PSU, the RAM or the mainboard itself unless you exchange every part with one that you know to work. The problem could be caused by any of these three, and a no name PSU is the most likely cause.

Mobo has 8-pin for the CPU power... but the PSU only has a 4-pin

The PSU 4-pin connector MUST be inserted correctly into the mobo's 8-pin socket. My N650SLI-DS4 did the same thing when I didn't connect the 4-pin PSU wires to the mobo.

It's possible that your mobo is improperly grounded to your case. With a new mobo, I always place the mobo on top of a box next to the computer case. This elimates the possiblility of a short circuit if there is a problem with the mobo's installation.

You should verify that the 4-pin PSU connector has voltage, yellow = positive and black = netative. Pages 22 & 23 in the mobo user manual deal with the ATX_12V hookup.

The last sentence in the 1st paragraph on page 23 says "If the 12V power connector is not connected, the computer will not start."
