"jonnyGURU, That's MTBF. MTBF rating is almost always at 25°C. MTBF does NOT always represent the temperature at which the unit is rated at."
Ok I agree the 25C Ultra lists on their site is MTBF. Now show me the ambient temp they rate the supply at. How do you know if they do not say? To me...
Yes that was my original argument.
"My simple example. Just to keep it simple I will use a 2 rail supply. Each 12 volt rail can put out 18 amps for a total of 36 amps. 12V1 powers all but the CPU. 12V2 power only the CPU. Now say the CPU draws a max of 10 amps. You have 8 amps that can never be...
"He could easily run two GT's regardless of how hot it gets in his case. It would be impossible to get your case temps down to 25°C because that's room temperature. But like I said, the X-Pro is rated at 40°C and even it was rated at 25°C it would be able to put out around 450W continuous...
Whats funny to me is it does not even follow the the 240 VA rule so why bother having split rails in the first place. The 240 VA was set for safety nothing more so this PSU is 2 faced.
I see the 700 watt 4 rail PSU you spun up looks quite nice. Does anyone make a PSU with these spec's? Can you give some examples of some smaller PSU's that still get round load balancing and trapped power problems? Say a 500 watt PSU with around 36 amps for the 12 volt as most people will never...
I just noticed you ended up buying a Ultra X-pro 600 for $50. I did some research and most reviews give it a thumbs up.
It's got to be about the best PSU you can get for $50. Of course I like the single 12v rail. I almost ordered one my self to replace the undersized PSU used in the rig in my...
"Just because a rail is designated at 18Amps doesn't mean that it will always be running at 18 Amps or that current is trapped on that rail if not in use. The whole point of 90% or multi-rail units out there is to take a single 12V source and split it up to go to different components. Then...
Vcore droop is done to lessen Vcore voltage overshoot when the load drops suddenly is part of Intel spec and is not a sign your PSU output voltages are sagging. Voltages from the PSU directly can and do hint to increased load.
Not with software, atleast as far as I know. An external meter will give you the total wattage your system draws. http://www.newegg.com/Product/...escription=Kill+A+Watt
I have the cheaper one and it works great.
Yup more rails trap more amperage but lessen the chance of load balancing problems.
Fewer rails trap less amperage but still do and they can have load balance problems and limit PSU's maximum wattage. The main reason many PSU manufactures are going back to single rail designs is not to save...
What I would buy to power your new rig including 8800 GT's in SLI.

If you want a real 800 plus watt PSU and have $280...
Sure you need some head room, I'd say 20% minimum over the max a system could possibly draw. I never said to use a under sized PSU I said that the Cooler Master Real Power Pro 850W will trap so much amperage do to the 6 rail design a quality 600 to 700 watt single rail PSU will do the same job...
Ok if you say so. I read jonnyGURU's post and what he said is good info and for the most part sound advice. The tone in which it was written tends to color reality.
Multi current limited rail PSU's exist for safety considerations only. There is no advantage to using a PSU that has muti...
No the PSU has to be able to supply the needed power that each rail requires.
Most multi rail supplies do not list how the rails are split and even if they do you may run into load balancing problems. Why even take the chance because as you stated "There's nothing in that article that...
Well its not bunk. A single rail supply can't have load balancing problems. Multi rail supplies can, some reading material. http://www.playtool.com/pages/...tirail/multirails.html
