Re: PSU - bust the myth

Decent PSUs have over-current protection (OCP) and should shut down (theoretically) whenever the rails' max amp rating is exceeded. However: - Sometimes the trigger point is set too high, and when overloaded the PSU fries before the protection can save it (relatively rare but not unknown, even from …

Re: PSU - bust the myth

Those are good PSUs but only 100w and 110w respectively on 3.3v+5V, so 90w-100w if you don't max 3.3v+5v out. You keep looking at PSUs with squat on 3.3v+5v. If that's what you want then those will do. . . But in the case the wattage requested is more on both rails, which kind of protection good …

Re: PSU - bust the myth

I am looking at the EVGA SuperNOVA 550 GS and it looks like good and not expensive too. What do you think of it and also on the 650 PS? The 550 G S is a good PSU but for a few more bucks I'd get the 550 G 2 , which is awesome (like all EVGA Supernovae G2/P2/T2). Thanks, I read the review. :) By the …

Re: PSU - bust the myth

Looked at jonnyguru and Hardware Secrets reviews. I haven't seen one personally. The Seasonic looks like an excellent PSU if it will work for your application. (Sorry, this thread is getting long and I forgot what you are working on.) With 125w 3.3v+5v and leaving 10% for a safety margin (to PSU …

Re: PSU - bust the myth

Your system must be drawing about 100~150W AC from the wall at full load. That's a small fraction of the VS650 rating, relatively little heat is generated inside the PSU. And the 120mm fan (which probably spins fast to give the Jun Fus some life expectancy) dispatches the heat out easily. ... I've …

Re: PSU - bust the myth

Nah, from what I read around the web the Voodoo 3 2000 may draw as little as only 10W. Doesn't even need additional power connector. Your Athlon Classic system is just a very light burden for the VS650, she's half-asleep while powering it. :happy: I bet the PSU's rear grill is stone cold at all …

Re: PSU - bust the myth

... 12,01V and 4,93V ... ... 11,98V and 4,96V ... ^ That's very little deviation! http://smileys.on-my-web.com/repository/Respect/respect-048.gif ... I suspect the Voodoo3 is asking a lot. What makes you think so? I can imagine not much difference between a Athlon and Duron at almost same freq/ …

Re: PSU - bust the myth

Is reading the 5V voltage the only way to understand if the psu is stressing and overloading or you must calculate every power components? To really KNOW how much the PSU is really drawing, we need amperage meters. A Kill-a-Watt is an amperage meter that reads total system draw from the wall. It …

Re: PSU - bust the myth

Is reading the 5V voltage the only way to understand if the psu is stressing and overloading or you must calculate every power components? With the multimeter the VS650 with Athlon 900 / 512 PC133 / Voodoo3 2000 / 4 PCI / 1HD / 1 DRIVE is at 12,01V and 4,93V at the drive connector. Bios reading was …

Re: PSU - bust the myth

Both +12V and +5V are a bit high? If so it's OK. Check with a multimeter to be sure. Ok, I will check from the drives connectors. The air that exit from the fan supply is cold. By the way I would buy a 1200W psu if it would give some 40A on the 5V but I see that they all go from 15A to 30A.. would …
