What Power Supply Should I Use (#5203)
You can look over our Poll of BBR overclocking members who tell what make power supply they use. You can find it Here feedback form by FastEddie last modified: 2004-02-07 12:34:38
How far off can my power supply rails be? (#9207)
Having strong rails on your PSU is a must for overclocking. In a perfect world you would want your rails to stay dead on their marks, but it doesn't happen. So here are the Max and Min values for each rail of the PSU. As long as your voltages are within these ranges you are ok. Higher is better though. feedback form by Exit edited by FastEddie last modified: 2004-02-08 12:59:24
How do I run my ATX power supply without a motherboard? (#9208)
Running an ATX power supply with no motherboard is quite simple. All you need to do is connect pins 13 (power on) and 14 (ground) with a wire or paperclip. Doing this shorts the power switch and turns on the PSU. You must keep these pins shorted as long as you want the PSU to be on. Here are some images of the pins that you need to connect. feedback form by Exit edited by FastEddie last modified: 2004-02-08 12:59:44
How can I check my voltages from Windows? (#9358)
The most commonly used program for this is Motherboard monitor 5. This program can not only read voltage levels but also fan speeds and system temperatures. Most motherboards are now automatically detected during setup so there is no configuration needed. If however you can't find your motherboard in the list of boards during setup look at this page to find which sensors on your motherboard correspond to which sensor in MBM. You can download MBM 5 here. feedback form by Exit edited by FastEddie last modified: 2004-02-15 11:42:07
How many Watts do I need? (#10746)
There is no simple answer to this question. Each and every system out there draws a different amount of current so you need to figure out what your system needs are. A good base line for modern computers today is a 350W power supply and no lower. AMD has a section in their guide to building desktop computers that addresses the issue of calculating power supply requirements for systems. Read pages 3-8 in this PDF Some testing of an overclocked AMD XP system by a forum member showed the following real life power draw of his system using a power meter. The system specs were DFI NFII Ultra Infinity Athlon XP-M 2500+ @ 2.2GHz (11 x 200 @ 1.55V) ATI Radeon 9700 Pro @ stock 3x Harddrives 2X Optical drives OCZ 2x256MB PC3500 EL @ 200MHz @ 2.6V 7 fans (1x120mm, 2x92mm, 3x80mm, 1x60mm), all running at the lowest possible speed Results Peak during bootup: 215W Idle: 151W Load: 179W (Idle is defined to be sitting at the desktop doing nothing, and load is defined to be running Prime95 torture test and 3DMark03 Mother Nature test with the vid card set to 4xAA/8xAF for as much load as possible on both the video card and CPU. Naturally this load result ignores the hard drives and optical drives (well the hard drives of course are spinning, but they use the maximum amount of power when actively seeking), and it ignores the sound card since the Mother Nature test doesn't use sound.) THG has shown us what happens when you put to much strain on a computer power supply. Read more here feedback form by Exit edited by FastEddie last modified: 2004-07-20 10:08:38
