My new pc-power issue

guernseynick · 03-31-2005, 09:04 PM

I am building a new pc. It has a fatal1ty motherboard, 3.4P4HT and about um...10 fans including one on the GPU. I have bought a cool looking chrome an led aerocool 320w PSU. since my system is reasonably powerful will this PSU limit its performance....with no oc'ing

Also will it limit its OC'ability?

What graphic card do you have. 320watts sounds low to me especially if you have a highend graphic card. It would be helpful if you said what the 12v line rating is.

i have a sapphire X700 pro. What u mean by 12v line rating? What should it be measured in and what sort of number....the box has got "15A and 180W below a +12v thingy?

The 15A was what am talking about. In general 15A is really low.

the guidelines for recommendation on psu has been outline by praetor

How Many Watts do I Need?!?
Ive seen this question asked too many times and although its indirectly answered Ill answer it more directly:
- If you are concerned about getting a PSU sufficient enough for a high end system (say a SLI setup), check out a PSU with at least 30A on the 12V rail
- If you are getting a PSU for a system with a single high end video card than 28A-32A should give plenty of room
- Midrange systems should shoot for 24A on the 12V rail
- Really low-end, older or specialty systems can consider 18A on the 12V rail
Realistically, anythingg below 18A on the12V rail should not be considered. Why specify by amperage rather than wattage? Well anything that can meet the amperage guidelines as noted above will provided enough power for your setup

sounds like your a midrange system so you should probely look for a PSU with 24A(or more) on the 12V line.
