Need a bigger power supply?

I just built a computer and it started up at first but is not anymore. I recently over clocked my processor. It is an Intel I7 920. I have a Radeon 4870x2 video card, 2 sata hard drives, 1 sata dvdrw and the case has 5 fans, 1 cpu fan, and I guess 2 fans on the video card. The MOBO is a ASRock x58 Super computer. I didn't over clock much just to about 3.3ghz

It just died all of a sudden as if the power went out. When I start up it has trouble starting up all together doesn't even reach the post and restarts then it eventually gets there and I get 1 long beep and 8 short beeps which I think has something to do with the video card.

So I'm thinking I don't have enough power. I have a 610W power supply

Does that sound like what it is to anyone else? Also what size should I go for. I still have a scsi card I'm going to add but nothing beyond that probably.

Thanks

Run your components thru the Extreme Power Supply Calculator, it'll tell you that 550 watts is more than enough.
Run them thru the Corsair Power Supply Finder and it will tell you that thier HX620 is plenty.
Unless there's a problem with your PCP&C, it is certainly enough power for your system specs.
You said you think the post beeps indicate a video issue, any way of testing the video card in another system ?

I found a power supply calculator that said I need 741w of power. I'm not sure but supposedly the 4870x2 uses 500w by itself. I'm thinking I need at least 750w. When my computer died it seemed like a power failure. I have no way of testing my video card in another system.

I guess I'll just get a bigger PSU and if I get the same problems I'll assume it is the video card and not the PSU.. I don't know what else to do.

OK i just ran it through the extreme power supply calculator and it says 836W power supply is needed. I think i'll go with a TX850

Anyone think this a bad idea?

actually nevermind I ran the extreme calc wrong.. I put quad socket thinking that meant quad cores.. but I guess single socket is all I need which is only 485W

I don't know what could be the problem though.. It seems like its a power issue.

It could very well be a psu issue, even the best quality units can fail.
Do you have access to a digital multimeter ? You could it use to check voltages when powering up.

i honestly think its got to be a power issue because it just started happening when I over clocked the cpu. When I first had it running the psu was underclocked i guess auto mode for energy saving but the cpu was running a little less than 2ghz even though it's a stock 2.6ghz cpu.. Now that i manually set the cpu it's at 3.3ghz constant and all of a sudden I'm having issues with the system powering up

Maybe it was too big an OC. Why not reset CMOS and see if it posts?

Maybe just overclocking period.
Here's a line from the Toms review of the board;
"By now many readers are probably wondering where our BIOS screenshots are. We normally test our motherboard before taking any BIOS screenshots, and the X58 SuperComputer failed during our overclocking tests. A second board exhibited the same behavior, preventing us from including BIOS screens."

If your not able to get it to run, i'd say psu or motherboard.

ASRock is a cheapo brand made board that has had always bios problems, bios flashing, etc. So i don't know why you went with ASRock - the limb of an ASUS.
