Last week I put together a new system:
Gigabyte GA-MA790FX-DS5 (BIOS F3 which includes the AMD patch). AMD Phenom 2.2GHz (quad-core) 4 x 1Gb Kingston KVR800D2N5/1G (on Gigabytes approved list). ATI Radeon X1650 graphics. 2 x Hitachi SATA disks. The usual stuff - DVD, CDRW, floppy.
The powersupply is rated for 350W. The cabinet has 2 extra fans. ^^^^ Hmm, have you read the manual, specifically page 23[0]?
<Snip>
Then I thought - might the powersupply be just a little too small?
Probably.
Which would seem to indicate that the powersupply is doing just fine.
Without using another one to confirm that, it's just a guess. My guess is that, under load, the system just sucks up too much for the PSU. This makes the voltages drop below the thresholds, and so it triggers the reboot.
I'm tempted to send back the motherboard tomorrow, but before I do - does anyone have any suggestions for other things to try?
Try another PSU of at least 400W[1], and more like a 500W one, to see if that makes a difference. [0] If you don't have a paper one, the electronic one is here: URL:http://europe.giga-byte.com/FileList/Manual/motherboard_manual_ga-ma790f... [1] That is the minimum the manual recommends, and it does say that using less will result in an "unstable or unbootable system."
