I have been building and upgrading my own computers for some years now but I was carrying out an upgrade the othernight and have hit a stumbling block and was hoping someone could help.

My current rig:
Intel Core 2 Quad Q6600 B3 (2.4GHz 1066MHz) Socket 775 L2 8MB Cache (2x4MB (4MB per core pair))
ASUS P5W DH Deluxe SKT 775 dual-core Core2Duo Conroe ready Crossfire 8channel audio ATX
2x Corsair 4GB Kit (2x2GB) DDR2 800MHz/PC2-6400 XMS2 Memory Kit CL5 1.9V
PowerColor HD 6950 2GB GDDR5 DVI HDMI 2mini DisplayPort PCI-E Graphics Card
Enermax 1000W Galaxy CrossFire EGA1000EWL ATX2.2 Modular PSU

My upgrades:
Intel Core i7 4771 3.50GHz Socket 1150 8MB
Gigabyte GA-Z87-HD3 Socket 1150 HDMI DVI ATX Motherboard
Crucial 16GB Kit (8GBx2) DDR3 1600 MT/s (PC3-12800) CL8 @1.5V Ballistix Tactical UDIMM 240pin
Samsung 250GB SSD 840 EVO

Once I had put everything together I tried to boot the PC but the power supply kept auto-tripping out. At first I thought I had blown the PSU during the upgrade (somehow) but when I tested it with my old motherboard it worked fine and would power up. Next I thought the new motherboard might be faulty but when connecting another PSU it works fine and boots to BIOS no problem.

I think that the problem is to do with the new lower power states of the Haswell chips. After some research I discovered that my Enermax power supply is fitted with some protection hardware which can shut down to prevent damage to other hardware, I’m guessing the new chip triggers some protection. The board will power up for a second and then the power supply cuts out, the LED turns red and I get a 2 beep-pause-2 beep pattern from the PSU.

My power supply is fairly old (bought in 2007) but still has more than enough power to run my PC so I would rather not replace it if possible. I have tried disabling C1e, C3 and C6/C7 states in the BIOS but it still will not boot. Has anyone else experienced this issue with an Enermax PSU or know a work around for it?

Thanks,
Tom

Well thank you for being ever so helpful. I probably will have to get a new power supply but if there is fix for this I would rather do that then shell out unnecessary money. I can't get a new one right now so all I can do now is find out if there is a fix or work-around.

Neither corsair nor XFX actually make PSUs. They slap their name on them. Usually made by Seasonic. But for example, I'd take an Enermax EPM600AWT over corsair's CX600 any day. Enermax makes some excellent PSUs.

To original poster, sorry for threadjacking. I'm going to go watch team Canada wipe Team USAs butt in women's olympic hockey!

Thanks - I'm aware that 1000W is more than enough but I like to keep some redundancy as I will be getting a new gfx card later in the year and I could decide to double them up (plus I was a bit flush when I bought my last one).
Also just realised I didn't put my current card into my specs:
"PowerColor HD 6950 2GB GDDR5 DVI HDMI 2mini DisplayPort PCI-E Graphics Card"

I will take a look at the 3 psus you suggested and get myself a new one soon.

Thank you - can I ask what you look for when picking a psu as the ones you have listed all seem very similar to me. I'm not sure what the differences are between them other than their make...
