hey guys just a bit paranoid i have relatively decent system:-

amd 1055t x6 @4.00ghz @akasa venom cpu cooler 23c idel 50c max load.
asus crosshair IV mobo
2x xfx 6870 xfire
4gb corsair dominator 1600mhz
xfx pro850w core edition psu
3 hard 3.5 inch 7200rpm disks
windows 7 ultimate 64 bit

evreything seems to be working as of now but 5 mins before this post it would post after i hit power button so i reset my power supply till there was no power at all going through my system fliped the switch back and it booted no problem now my concern is is there anything wrong with my system as to why this would happen only thing i can think of is last night when i was shutting down the system hanged on shutting down screen for about 1hour till i manually switched it off.

thanks guys

At first glance, I don't see anything in the hardware that could immediately point to a problem. I'm not too familiar with XFX brand PSU's so I did a search on your model, found this review. http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story6&reid=217 Overall a good performing unit, though the reviewer did note that the 3.3v and 5v rails aren't so great on regulation. If I remember correctly, those rails power your smaller peripherals like hard drives and optical drives, so maybe something like the initial power surge of 3 drives and however many other devices including USB stuff is drawing from your smaller voltage rails and causing an issue. Are you able to disconnect some of your peripherals to the bare minimum and try a boot up that way? Another option would be to try a different PSU for a test to see if that changes the symptoms you are seeing.

haha i have 19 usb attachtments i removed my controllers and wacom tablets and it seems to be okay it booted 1st time just there im just relived that i havent got damaged hardware thanks for the reply mate im not so hot when it comes to the power stuff it scares me i also have alot of computers drawing power from the mains. as i build pcs for a hobby so got a few lesser systems on that my friends use for lan parties so would that affect it aswell ? thanks

that depends on how the circuits are setup in your house. If you are in the US, most individual circuits are rated at about 15 to 20 Amps. If you have more than 10 friends and a bunch of lights or other appliances also plugged into the same circuit, you'd trip the breaker, but not cause any damage necessarily. You'd have to move them to another circuit in a different part of the house is all.

ive only got 2 running including this one im in the UK but live in an old ass house like 200 years old or something but its been rewired since then so i think im in the clear until i have a lan party but most of the other sytems are low power users around 300 watts a piece only the other 2 are using around 600+ . im glad i did my research on tht xfx psu and im really happy with it ive had no problems in a year with it until the scare this afternoon. when i didnt hear a post i was like *** and panicked so thanks again mate
