carl0s Posted October 23, 2007 Share Posted October 23, 2007 I think my PSU is 450w actually, but it replaced a cheaper, older 450w PSU which wasn't up to scratch. It's a bit like the audio-amplifier world I suppose, with regard to watts Link to comment Share on other sites More sharing options...
Sheefa Posted October 23, 2007 Author Share Posted October 23, 2007 I know Homer, not cheap at all. In fact £100 really for an 800watt one. Might just bite the bullet anyway, after all it comes in at a lot cheaper than running my old Supra!! Link to comment Share on other sites More sharing options...
carl0s Posted October 23, 2007 Share Posted October 23, 2007 Also somewhat related: http://www.xbitlabs.com/forum/viewtopic.php?t=13667 It may turn out to be your PSU, perhaps it's vastly overrated/shite (although Enermax is #1 in the Top 5 PSU brands in the above url), but (genuine) 800 or 1,000w is OTT IMO.

Sheefa Posted October 23, 2007 Author Share Posted October 23, 2007 Thanks Carlos - so what is am rail ampage or whatever he's going on about then??! I have the Enermax 485watt Noisetaker PSU and would of thought that should be fine. Link to comment Share on other sites More sharing options...
carl0s Posted October 23, 2007 Share Posted October 23, 2007 Thanks Carlos - so what is am rail ampage or whatever he's going on about then??! I have the Enermax 485watt Noisetaker PSU and would of thought that should be fine. There should be a small-print saying 12v1 + 12v2 max XXwatts, say it's 420watts. Watts / Voltage = amps, so in this example it's 35amps maximum available overall on 12v. This is different to the individual maximum available on the separate 12v rails, which might say 12v1 = 26amps, 12v2 = 22amps, or +12v 26amps, -12v 22amps. You can't draw the maximum amps of each rail together, you're limited by the overall combined supply max. Or something. I don't really play with overclocking stuff, I just buy stuff that does the job and works Link to comment Share on other sites More sharing options...
Sparky Posted October 24, 2007 Share Posted October 24, 2007 Hi guys, It's a ENERMAX NOISETAKER II EG495AX-VE PSU that puts out 485 watts so should be fine. The card only needs 450 and I'm not under heavy load - just running 3gb of memory. Motherboard is a Abit Fatal1ty AN8 SLi Motherboard inc uGURU panel running a AMD64 4600+ X2 CPU. Not sure if the firmware is up to date Darryl, I'm using the standard drivers that came with the mobo on disk mate. Memory: GeIL 2GB (2x1GB) PC3200 Value Dual Channel Kit CAS3 (GE2GB3200BDC) Memory Latency: CAS 3.0 8-4-4 @ DDR400 PC3200 Hope that helps Thanks, Greg 480w should be fine although tbh i wouldnt trust the brand of psu that you have. Its more than likely a faulty Graphics card. Send it back and replace it and if that doesnt work then replace the psu with something more powerfull like an 800w Hyper psu. I was running a 5000 athlon am2 cpu, 2gb memory and a geforce 8800gt with 2 raptor hdd's in a raid and i only had a 400w psu powering it for 3 months. I could tell it wasnt happy but it still worked ok! Link to comment Share on other sites More sharing options...
RedM Posted October 24, 2007 Share Posted October 24, 2007 ...and this is exactly why I've given up on PC gaming. I went to upgrade my gfx card and realised I'd need a PSU upgrade as well. I just couldn't be bothered. Link to comment Share on other sites More sharing options...
Alex Posted October 24, 2007 Share Posted October 24, 2007 I've been using a 650w Coolmaster - it's highly efficient, quiet and running 4xHDD's and 2x Optical drives + a 7900GTO.... Link to comment Share on other sites More sharing options...
colsoop Posted October 24, 2007 Share Posted October 24, 2007 Try and unplug the rest of the devices (cd, dvd, usb hub etc)from your system and see if it powers up. Link to comment Share on other sites More sharing options...
