Power supply -- this time it's 350W - Alex Belits
Power supply -- this time it's 350W
Today I have made a new power supply using a 350W board -- before I have only used 400W ones, and the layout of the heatsinks is different on the 350W board, so very soon I have found out that the airflow distribution doesn't work too well with it, some of the air just passes around the board, without doing anything. I have added a small aluminum wall, and it looks like the airflow over the high-voltage heatsink (you DON'T WANT TO OVERHEAT anything on it) is now sufficient, and the box is now running cpuburn, still with the giant original CPU heatsinks sticking out of the otherwise 1u case.

I am still not sure if it's a good idea to use 350W power supply in a box like this, so I am going to build 400W and 460W (for Opterons) versions, and see how well they will perform.

Tomorrow I will finally assemble the whole thing with the new brackets and covers, and install the cooling systems, thus making a box suitable for testing (and later for replacing a ridiculously underpowered mail/web/DNS box).

Current Mood: tired tired

How much power does mail/web/dns need? :)

Or is this one that handles your personal 50k item mailbox?

oh, no!
Alex deleted half of his messages?

No, merely sorted the mailing lists and spam into the separate mailboxes. However since then the number was growing again, and the copy of your comment is sitting under the number 294390.

It's the same box. It also runs a mysql server.
