Napajalnik 350W bo dovolj? Katerega?

Kupi LC 550W

6W (tipkovnica+miška) + 3W /fan) + 10-25W (integrirana grafična kartica) + 64W (RAM), 25W maš dvd RW, matična 30W, pa procesor ene 100W max. Pa še USB pa kakšne drobnarije. ti pride tam pod 300W sigurno. Tako da bo.

Nekaj informativnih primerjav:

--------------------------
94W-160W
Core 2 Duo E6600 (Socket 775, 2.4GHz, 4MB L2 cache), ASUS P5LD2 SE board (i945P), 2 GB DDR2 RAM, Palit Radeon X800GTO with 256MB RAM, Realtek 8169 ethernet card, 1 250GB SATA hard disk, 1 DVD-ROM drive, 1 DVD-RW drive, DTK 400W power supply. 94W idle under Linux, 160W gaming under Windows. With a Radeon X550 (instead of the X800GTO) under Linux, we see the following with a pure CPU load (the same used on other boxes; there are more energy-hungry loads):

clock idle load 1 load 2
1600MHz 85W 94W 100W
2400MHz 86W 105W 115W

Moreover, we tried a few different graphics cards on this machine, and measured the following (under Windows):

Card idle UT2004 Aquamark
Radeon X550 86W 122W
Radeon X800GTO 94W 163W
Radeon X850XT 104W 181W 190W

83W-180W
Athlon 64 3200+ (Socket 754, 2GHz, 1MB L2 cache, Clawhammer C0 stepping), Asus K8VSE Deluxe (VIA K8T800), Gforce4Ti4200 AGP with 64MB RAM, 512MB PC2700 RAM with ECC, Creative Audigy soundcard, NE2000PCI clone Ethernet card, 2 IDE hard disks, 1 LG CDRW drive, 1 Liteon DVD+RW drive, floppy drive, Enermax-EG365AX-VE(G) ATX12V power supply. 120W idle under Linux (without OS support for Cool&Quiet) with one disk spinning, 160W when running oggenc under Linux, 180W when playing a game under Windows.

~15W less with a Radeon 9600 (instead of the Gforce 4200). ~20W less when idle under Linux with cpufreq (Cool'n'Quiet support) @800MHz. With these changes, ~83W when idle, ~145W compiling, ~160W gaming.

83W-143W
Athlon 64 X2 4400+ (Socket 939, 2.2GHz, 2*1MB L2 cache, cpu family 15 model 35), Tyan S2865AG2NRF Tomcat K8E, on-board graphics (ATI Rage XL) in text mode, 4GB PC3200 DDR ECC SDRAM, 2 300GB hard disks spinning, 1 DVD-RW drive, Tagan TG480-U22 power supply.

|------ power ------|
clock voltage idle load 1 load 2
1000MHz 1200mV 83W 93W 102W
1800MHz 1250mV 86W 103W 121W
2000MHz 1300mV 88W 109W 130W
2200MHz 1350mV 92W 116W 143W

A very similar machine, but with an Athlon 64 X2 4600+ (cpu family 15 model 43) consumes as follows:

|------ power ------|
clock voltage idle load 1 load 2
1000MHz 1200mV 89W 98W 106W
1800MHz 1200mV 90W 105W 120W
2000MHz 1250mV 93W 112W 131W
2200MHz 1300mV 98W 120W 144W
2400MHz 1300mV 98W 122W 149W

BTW, load is a pure CPU load. We found significantly higher power consumption for a memory-bound load (~147W on the second system with load 1, and up to 160W with load 2; additional core-intensive work and maybe some I/O to a PCIe graphics card should increase the power some more).

jst ti tud priporočam najmanj 550 če misliš še kaj dograjevat kasneje.
