Re: best long term psu silent

You can measure +12V and +5V on a molex connector. It has four cables; yellow, red and two black. Between yellow and black you should have 12 volts and between red and black you should have 5 volts. https://upload.wikimedia.org/wikipedia/commons/thumb/3/31/Molex_female_connector.jpg/320px-Molex_fema...

Re: what does a system needs to run 3 browser with 8 tab each

Sure, 4GB is not much today. But it depends on what you run. Windows needs more overhead than for example Linux Mint XFCE for sure. On the HTPC I have ~3.5GB available for the system and about 1.15GB used with 10+ tabs in Firefox. Just over 300MB used when I close Firefox.

Re: best long term psu silent

The PSU takes AC mains in and outputs several DC voltages, +12v and +5v and others. Those are called rails and you can measure them. For example, the ATX specs says that the 12 volt rail should be 12 volts plus or minus 5%. So between 11.4 and 12.6 volts. One way to know if a PSU is failing is to me...

Re: what does a system needs to run 3 browser with 8 tab each

DDR4 is a bit faster than DDR3. DDR3 is a bit faster than DDR2 etc. The motherboard will dictate what kind of RAM you need. Today it's DDR4 for new stuff. Capacity is apart from this. Car analogy; the speed of the car have little influence on how much goes into the trunk. If you need say 8GB of RAM ...

Re: what does a system needs to run 3 browser with 8 tab each

The GPU has little influence on the browsing experience. And 8GB RAM should be fine for many systems as well. Even 4GB for a modest system. Memory usage is pretty individual, it depends on what programs you are running and how many you run at the same time. Best to check your own memory usage to get...

Re: best long term psu silent

Of course the PSU can damage other components. If the PSU is faulty. One may suspect the PSU if other components die for no apparent reason, but one does not usually replace the PSU just because other components have failed. A multimeter or a PSU tester or something can help deciding if the PSU is d...

Re: 3.5" HDD dock - recommendation please

I have a generic version with both USB2 and eSATA. Only use eSATA on a regular basis. It has served me well over the years. Power is supplied via a DC jack, so any 12V adapter will work. I use a 1.5A adapter that originally came with another external HDD.

Mine looks a lot like this.

Re: Is there a heat difference between different 35W T CPUs?

Number of cores and top clock frequency will tell you more than TDP I think. It's a jungle. Some 54W TDP CPUs will output less heat than some 35W TDP CPUs for example. Now with the latest generations it seems that the motherboard plays a part as well.

Re: Explanation of why this forum doesn't like T series cpus

They are good for specific uses. I got a Sandy Bridge i3-2100T once and the reason for that was first that it was on sale and second that I was limited on the PSU side (60W power brick, lots of HDDs) and no ideal way to manually underclock. Performance wise it was overkill anyway for my use case. Wh...

Placing it in the kitchen on top of a fridge may not be a good idea -- it's usually quite warm there from the fridge's heat exchanger.

Re: Which is faster, dual-core G3240 or quad-core i5-4460T?

Interesting. 500mA is just the USB specification. How it works in the real world depends on a lot of stuff. I'm guessing both ports can deliver 500mA just fine but the drive needs a bit more while spinning up. The +5V and ground for both these ports are the same. There's resistance in the traces and...

It's 500mA per port. And SilverStone make decent stuff. That 300W unit will be more than enough, unless it's ancient with weak +12V rail. Usually it's the other way around when building a low power system; you end up with a overpowered power supply because there simply is no market for very low powe...

5V × 1.5A + 12V × 2.0A = 31.5 W. That is the highest consumption, which is not very likely in real life. Am I right? What it says about power consumption is indirectly. The power requirements are stated. So we can conclude that the device should not draw more than that. But it says nothing about th...

http://i.ebayimg.com/images/g/rkwAAOSwPsBa~CIS/s-l1600.jpg It says "5 V/12 V = 1.5 A/2.0 A". Should the highest consumption be 12V × 2.0A=24 W? No, the power requirements are 5V 1.5A and 12V 2.0A. That's worst case, with a good margin to be sure, and the drive will not ever draw that much in real l...

Yes, that's a reasonable figure. A bit high perhaps, the motherboard is not 40W I think, the DVD perhaps not 27W. What's worrying me is the fans. ;) 80mm and 60mm fans will often make noise while moving meaningful amounts of air. What case will you be using?

What is it you are trying to do? :) Do you want something less power hungry than the G3240? If it gets too hot, or if you want to lower the power consumption (at load) you could try underclocking it. https://outervision.com/b/aKHCZP (With Core i5-4460T, the total is 219 W.) https://outervision.com/b...

Faster at multi threaded tasks, perhaps a bit slower at single thread stuff. Power consumption would be about the same I think. Cheap dual core vs. T-branded chip usually shows the disparity between stated TDP and power consumption in real life.
