i have a Seasonic S12-600HT 600W ATX12V 20/24 Pin V2.0 Active PFC Power Supply the idle temperature is 33c, the 100% load temperature in about 30 minutes period is the highest at 49c is that too high? the PSU already has a 120mm fan... plus i have two 120mm case fans. my cpu temperature is loaded at 40c on a x2 3800+ @ 2.3ghz with a big typhoon fan
I go from about 32c to about 42c and I have no idea if thats normal or not. I thought I was running hot, I used to never break 40 before changing to a SATA HD
Sounds about right for a 600W PSU. It will generate more heat because it's supplying more wattage and current per volt thus the higher temp. To be expected tbh
That's very good for a power supply. I expect that the components will have a tolerance of over 80°C, so it's nothing to worry about.
No it's not... any power supply will only provide what is demanded of it. If you rig requires 480 watts, then that's what it will draw, no matter what the capacity of your PSU. So.. a 600 watt supply in that case will run cooler than a 500 watt one, because the 500 watt device is almost running flat out, whereas the 600 watt devise is loafing along.
no thats not right ....... a powersuppply isnt workin this way ... ..example: if u require 200 watts for ure Pc hardware ure power supply will use more then 200 watts (about 220 w - 250 w) ... a good power supply is more efficient then a bad one... because my english sucks ...im just copy and paste related text here: Most power supply manufacturers offer solutions that often require compromises in efficiency, dissipated heat, and size. The efficiencies of these supplies typically range from 75% to 90% and have power densities that vary from about 1 to about 8 W/in.3 One solution to the problem of thermal management is distributed-power magnetics (DPM), developed by OnLine Power Supply. The technology provides one solution for power supply efficiency, thermal, and size problems, and allows a supply to operate at efficiencies of up to 97%, with a power density as high as 14 W/in.3 Calculating dissipation To correctly design the system cooling for an application, the dissipation of the power supply must be calculated. The calculation is Dissipation = (rated power) efficiency – (rated power). To compare an 80%-efficient power supply to one that is 90% efficient, the calculation would look like this 80% efficient supply: 1,000 W/0.8 –1,000 = 250 W of dissipation, 90% efficient supply: 1,000 W/0.9 – 1,000 = 111 W of dissipation. Two significant benefits arise from having a more-efficient power supply: (1) improved reliability, from lowering the overall system temperature, and (2) reduced system cost, which comes from specifying a smaller cooling system. This makes using power supplies with the highest efficiencies critically important to today's sophisticated designs another text: While the best power supplies are more than 90% efficient, some are only 20 to 40% efficient, wasting the majority of the electricity that passes through them. As a result, today's power supplies consume at least 2% of all U.S. electricity production. More efficient power supply designs could cut that usage in half, saving nearly $3 billion and about 24 million tons of carbon dioxide emissions per year.
No - Pookeyhead is right. A 600 watt supply will usually run cooler than a 500 watt one when delivering the same load, since the 600W model will have an improved cooling system to deal with the higher heat output. The waste heat will be different for each, seeing as the efficiency curve for a good PSU will peak at about 80% load, but the 600W will likely end out cooler. The exception is when the same schematic is used for two power supplies but with the higher wattage model simply rated at a higher temperature. In this case, the 600W one will be at the higher temperature.
Hang on.. I said that a PSU will supply whatever power is demanded of it, and therefore a 600 watt supply will be cooler than a 500 watt.. am I missing something, but have you just given an overly complicated, but essentially identical answer?
