wherewolf Posted January 5, 2008 Share Posted January 5, 2008 Hi all! I'm new to this forum. And now I hope you guys can help me out? I have, as said a HX 520W that serves me very well. But I'm just a bit conserned about the voltage on the +12V, since I swapped my GF 7950GT to a 8800GT. With my previous 7950GT (Gainward Golden Sample, factory oc'ed) I had 11.90 V stable on the +12V. But after swapping to the 8800GT, I just have 11.840V (stable). I have tried both PCI E connections on the psu. Both shows the same Voltage. That is in both the bios, pc health menue and in the Nextsensor monitor program. Do I have a problem here? The +3.3V and + 5V rails looks o.k. I would like to add. Or is this just the normal power draw that the 8800GT use? Link to comment Share on other sites More sharing options...
kasutaja Posted January 5, 2008 Share Posted January 5, 2008 use a multimeter to measure the real voltages. software is usually wrong (for me it shows 12v @ 2v and that is wrong) and takes its values from bios which shows the wrong values.

wherewolf Posted January 5, 2008 Author Share Posted January 5, 2008 Hi! And thanks for your ansver. Unfortunatly, I dont own a multimeter, and dont know how to handle it either. Link to comment Share on other sites More sharing options...
EliteKiller Posted January 5, 2008 Share Posted January 5, 2008 Unfortunatly, I dont own a multimeter, and dont know how to handle it either. You can pick up a decent DMM for ~$20. Here's how you handle it: http://www.motherboards.org/articles/guides/1487_6.html Link to comment Share on other sites More sharing options...

Corsair Employees RAM GUY Posted January 7, 2008 Corsair Employees Share Posted January 7, 2008 Thank's man! As long as the rails all remain within 5% of its rating (12v rail would be anything from 11.4 -12.6) there should be nothing to worry about!

JoeBob Posted January 8, 2008 Share Posted January 8, 2008 Hi all! I'm new to this forum. And now I hope you guys can help me out? I have, as said a HX 520W that serves me very well. [...] HX PSU tests I've seen, usually shows the 12V rail deviating a bit over 1% under maximum load (i.e 520W, something that is impossible to reach unless your computer is loaded down with SLI'd high end graphics cards and has a quad core overclocked into oblivion). Anyways, as stated, 5% is the upper limit. Link to comment Share on other sites More sharing options...
