Hi guys, I bought a HD6770 which fails to boot, it does boot but after like a minute of spinning its fan up and down. Even though I have a good brand PSU: OCZ StealthXStream 500watts which is good enough for this card, I want to test my power supply before returing the card. I was collecting components for ivy bridge so I was going to buy a new psu in the future anyway. Help me decide which one should I buy please:
1. The OCZ 650watts: http://www.scan.co.uk/products/650w-psu-ocz-technology-...
or
2. The Corsair 600watts: http://www.novatech.co.uk/products/components/powersupp...
Similar Price but the Corsair 600 watt one has 2x 6-pin PciE and 6x SATA where as the OCZ has 1x 6-pin PciE, 1x 6+2-pin PciE and 8x SATA. I like the OCZ one more but just want to take some opinions from the community. Thank you.

I had used a OCZ Z(before the ZS came out) series on another build and it worked just fine.
The OCZ is rated for a bit more 12 volt power(6 amps or 72 watts).
The 6+2 pin connector can deliver 150 watts vs 75 of the standard 6 pin.
A post issue does not always mean a bad power supply.
try to disconnect anything you are not using. Sometimes USB devices(printers and card readers are most common) cause the post to hang(but it is more common with older boards). It also never hurts to remove all but one stick of memory just for test. Disconnect hard drives and DVD drives as well. Just to get into the bios. Once you get to that point, you can start putting parts back in.

Thanks for the reply guys. Nuke master I have done what you have suggested already, I disconnected everything even the system fans except for the CPU fan, the HDD, the DVD Drive, and took out all the ram sticks and swapped them around in different slots to see if it works still it wont boot normally. After taking the motherboard battery out for like 1 hour to reset the cmos the computer boots a bit faster but it is still stuck at post. My motherboard is a gigabyte GA-73pvm-s2h with 2.5gb of 800mhz and 667 mhz ram and E5200 dual core CPU. I am thinking this might be a bad capacitor inside the PSU as the capacitors seem fine on the motherboard and the onboard and previous GPU worked perfectly fine and the computer booted as it should giving the usual 1 beep it does before showing post.

Seems like I am not the only one with this sort of issue: http://www.tomshardware.co.uk/forum/336540-15-radeon-67.... she went and bought a different card though

Hey thanks man, I like that XFX one seems to give 53 amps on the 12v rail whereas the OCZ gives 46 amps I beleive and the XFX is free delivery ? Now I am confused. so give me some more opinions people, is XFX a good brand and would I be fine with 650watts for a 4 core Ivy Bridge medium overclocked, 8 - 16 gb of ram and two hard drives with HD6770 when I eventually build the new computer after ivy bridge comes out ? :S

A 650W psu is overkill for a 6770,you could easily run your gear with a good 450-500w psu.

cheers for the reply mate, I think I need a 650 watts because I will buy another card maybe and crossfire these or maybe after 3/4 years when I see a good card I will upgrade it, I always do this with my PCs the current pc I have had since like 2008 and its been playing almost all the games until now so I am updating

Fair enough, and i whole heartedly agree,i think the 650w range is the best overall for flexibilty.

ok and thanks nukemaster, davcon and everyone else for the help. I am buying the XFX 650watt PSU. but still does someone knows what might be wrong with my current setup ? and I just remembered my hearing is really sensitive and the first time I plugged in the computer with this card I heard a very very quiet high frequency noise I dont know where it came from but havent heard it again so far.

Some power supplies(can be heard) charge up the capacitors when plug it in causing a similar noise. Since a power supply does not shut off them the computer is off, it would only do it again after a power out or being switched off/unplugged and plugged in a few min later.I started my computer again after probably more than 1 and a half hour and didnt hear anything
