consider when buying your next powersupply
i always new that there is a huge misconception about how much power a PC needs, but i came across a thread elsewhere, where specs and wattage has been recorded, the results were more suprising that i thought.
looks like the gfx card is the biggest factor, but still i think psu manufacturers have been misleading people for a while? here's some examples Q6600 @ 3.5Gig. 1.41v 8Gb RAM MSI P45 Neo2 Motherboard Asus 8800GT gfx @ 700/2000 3x WD RE3 250Gb drives in RAID0 1x Samsung 1Tb drive Creative XFi Fatality with drive bay 1x 200mm, 4x 120mm LED case fans 1x DVD-RW Hiper 630w PSU (recent 85% efficient model) And all of that draws... 167w at idle (with speedstep) 300w at full load, i.e. Prime95 on all cores 326w at full load, running Prime95 and in game Left4Dead at the same time! Q6600 at stock 2.4 Freezer 7 Pro Gigabyte motherboard with on-board graphics 4GB RAM One 320GB hard drive One DVD-RW drive 2 x 80mm and one 120mm case fan Figures: 70-75w Idle (with speedstep and voltage reduction) 125w Deep Fritz 10 4CPU Engine mark 159w Intel Burn Test using maximum RAM E5200@3.6Ghz Gigabyte P35 DS3R Sapphire HD3850Pro 512mb 4x1GB pc2-5300 320Gb Seagate 7200.10 Sata hdd LG 22x Dual Layer DVDRW 4x 120mm fans AF Freezer 7 Pro Zalman ZM-MFC2 multi-function controller (live power consumption display) Enermax Pro 82+ 385w psu. Idle 85w (speedstep enabled) Load 118w (prime 95) Max Load 201w (Prime 95 + Fur stability test) Normal load is 158 while gaming. QX6700 @ 2.93 (stock volts, multiplier overclock) ASUS P5Q Deluxe 8GB RAM ATI 3870 video card 2 x 320GB hard drives 1 DVD-RW drive 2 x 120mm, 1 x 60mm case fans Corsair 620w Figures: 135w Idle approx (speedstep and voltage reduction) 205w Quad Fritz 10 4CPU Engine mark i7 920 @ 3.8 Ghz 1.32v ASUS P6T Deluxe Palm Edition. 6 GB Corsair DDR3 1333Mhz RAM.

Load = 250 Watts (Prime 95 - 8 cores) DFI Lan Party DK 790FXB-M2RSH Phenom 9850BE 4GB 8500 4850 512MB 6 hdd's X3 DVD±RW, Blu-Ray Rewriter/HD-DVD ROM x1 36cm fan, x1 25cm fan, x1 17cm fan, x1 12cm fan x4 AC Ryan 12" CCFL Zalman ZM-MFC2 Multi Fan Controller/power load meter monitor pci dvb-s2 card, pci-e dual dvb-t card X-Fi XtremeGamer Hi-Power 900W Modular idle at 251w , underload when gaming is 367w E7200 overclocked to 3.8Ghz Crucial 2GB kit Ballistix DDR2 hiper 530watt power supply palit 9600GT 512mb antec 1200 with 6 fans watercooling kit 2x LG 22x dvd writers 1x Samsung Spin Point F1 SATAII NCQ 500GB 16Mb 1x Seagate Barracuda 7200.10 160GB 1x Western Digital 640Gb blue Idle on window desktop 138watts Gaming for 2 hours on call of duty world of war 263 watts 6400+ be, 3200mhz/1.275v ax78 4gb 8500 ram 2* 3870xt 4hdd 2pumps 10 fans sound card wireless card dvdrw tagan 2force 2 600w idle 158w load (cpu) ~230w load - cf aware game ~320-360w idle with just 1 gfx card is closer to 120w laptop by comparison full load 85w (3400+ clawhammer, 9700 mobility, 17" screen max brightness) idle of ~30w the list goes on. i can see several outcomes if u read this. 1 you don't care at all either way 2 you will save yourself a nice amount of money on your next upgrade 3 you actually pay the electric bill yourself so you might buy a more efficient system for example the system with the following setup consumes just 53 watts when the system is runnning * Intel® Wolfdale E5200 Dual-Core, 1.2GHz/2.5GHz (1.08vCore) * Thermalright Ultra 120 Extreme (Passive) * 2GB PC2-5300 @ PC2-6400 4-4-4-12 (1.82vDimm) * ASUS P5Q-EM microATX Motherboard (Intel® G45 Express) * Integrated Intel® GMA X4500HD Graphics * Seagate Momentus 7200.3 80GB 2.5" Laptop Hard Drive * Western Digital 1TB Caviar® Green™ 3.5" Desktop Hard Drive * Sony DRU-190s 20x SATA DVD-RW * Sharkoon 120mm Silent Eagle 1000 Blue Led Edition (x3) * Antec 140mm TriCool™ Fan (low) * Antec Earthwatts 380 PSU * Antec 300 Chassis impressive stuff |
