rud3bwoy Posted September 22, 2008 Posted September 22, 2008 SPECS IS Intel Q9450 @ 3.5 Ghz|8 GIGS ddr 2 800 mhz|ATI 4870 X2 in cross fire|Vista Ultimate x64| Asus rampage Formula|2 3.0 MB Drives 500 gigs|XFI Xtreme music|Water Cooled|Antec 1200 case|Ultra x3 1000 watts| now when i got the other 4870x2 i added a new psu from a ultra x3 800 to a ultra x3 1000 now since i got the new psu i have been having hd issues where the hds were not being picked up,after a few reboots it will get detected,after a reboot it would not,so today i switched out the psu back to my 800 and everything is fine 100 percent no issues,so i guess the new psu is screwed now i gamed on the 800 watts for 1 hour and it ran fine on quad fire 4870x2 so my dilemma is stick with the 800 watts as it is running my system stable,or go back and get my 250 for the 1000 watts or switch it and use the 1000?

davidst Posted September 22, 2008 Posted September 22, 2008 yea I'd return the 1000 and run on the 800, it's like the old saying new is not always better the 800 may be better than it is rated and the 1000 could have bad caps who knows it's all made in china. <_< Quote Share this post Link to post Share on other sites More sharing options...

jammin Posted September 22, 2008 Posted September 22, 2008 Seeing as the 800W is working would suggest there is some kind of fault with the 1000W version, I agree. So I would certainly take the 1000W back and get a refund or a replacement. As for whether you should stick with the 800W in the long run, I'm honestly not sure about. It would be great to grab a power meter and check yourself how much you are drawing. Most reviews I have seen put crossfire power consumption in the 750-800W area under load (here, here and here). I don't know if those are taking efficiency (AC-DC) into consideration or not. So it's possible gaming will be pushing the PSU quite hard. Does the fan spin up very noticeably when you do? Because that would be a good indicator. Basically I probably would be more comfortable running on a 1KW unit (which is something I actually find hard to type ).

jammin Posted September 22, 2008 Posted September 22, 2008 I guess the rest of the fans drown out the PSU fan then. It may be that the PSU fan doesn't get that loud even when running at full speed, in which case it would be very hard to tell.

Zertz Posted September 22, 2008 Posted September 22, 2008 (edited) I don't know if those are taking efficiency (AC-DC) into consideration or not. I'm pretty sure those numbers are taken at the wall, so efficiency does come into play. So component's real consumption is a bit lower, but it's still 750W on a 800W PSU, it's within ratings, but some extra overhead isn't bad either I'd get that 1000W replaced or refunded Edited September 22, 2008 by Zertz Quote Share this post Link to post Share on other sites More sharing options...

rud3bwoy Posted September 22, 2008 Posted September 22, 2008 Well switched the psu so far no problems lets just hope it stays this way,on a side note i also got to oc to 3.6 ghz stable how how is a psu suppose to be running?cause the top of mines is hot at times?

Mine makes the top of the case warm and the metal of it on the back is mildly warm, not hot at all. Quote Share this post Link to post Share on other sites More sharing options...
