Re: server with laptoplike performance and power consumption

I've seen what people do to crack HDMI encoding, I think you want to avoid that if at all possible. Analog video capture would use way too much disk space.

If at all possible use a tuner.

Re: Mini-ITX A10-5700 power numbers, Turbo Core influence

Have you tested the efficiency?

Relying on specs does not always work, I've heard of at least one brick that missed its specs badly, I doubt its uncommon.

Re: Mini-ITX A10-5700 power numbers, Turbo Core influence

A picopsu might be 89% average efficiency but that's just going from 12v to 5v and 3.3v, but that ignores the efficiency of the brick and at full load you might not be getting "average" efficiency. If your brick is 80% efficient at that load, 25+ watts is lost heat and after you subtract a few watts...

Adventures in PSU modding: 23 watt idle i3-3220 + Radeon7790

I decided I want to do a little gaming so looking through my spares and internet reviews I decided to build this: i5-3570k, dz75ml-45k motherboard, 8gb Samsung green ram, Asus HD7790 video card, Samsung 840 Pro ssd, and a cheap case.

Re: Wiring a PicoPSU in parallel with PCI-E?

Well mostly I think any GPU that draws more power through the slot than through the PCIe 12v plug has a very poorly designed circuit board (more resistance between the PCIe 12v connector and the load than through the card edge, motherboard traces and the ATX 24 pin connector). It looked like the wor...

If you haven't bought yet, you can try to put together a budget.

I think ivy bridge has some life left in it and you can ge...

I would be really surprised if your GPU was broken up in to two separate circuits that each draw 75 watts. My assumption is that the PCIe connector ground and 12v lines are electrically connected to the ground and 12v traces on the card edge connectors. If the PCIe cable has less resistance than goi...

For people who don't know, transistors are kind of like dimmer switches and that region between all the way on and all the way off is called the linear region.

Re: Wiring a PicoPSU in parallel with PCI-E?

I'm guessing that it might make more sense to connect the remote sense wire to the PCIe connector because the motherboard probably does not draw as much 12v current as the video card and the picopsu is a dc-dc switcher, the 5v and 3.3v lines are going to be regulated the same unless your 12v line dr...

Re: How do I remove/re-attach fan to Xigmatek HDT-D1284?

I found it easier to remove two of the rubber parts from one side of the fan frame, slide them between the fins, then slide the fan on sideways and pull the rubber parts through the holes in the fan frame to finish.

Hard to describe in words, I hope you know what I mean.

Re: How do I remove/re-attach fan to Xigmatek HDT-D1284?

The Gaia fan mounts similarly and I removed it by pulling the fan and two of the little lugs to one side, popping out the lugs and rotating the fan to the side to detach the other two.

The S1284 is probably similar but I haven't gotten my hands on one yet.

The heat in the PSU issue really died when 80+ PSUs became widely available.

The place where things can go wrong is in the air flow. PSUs ar...
