Minimum power supply needed

orca234 · 17 Jan 2009 at 15:09

If my computer consist of these compenets...
- Asus P5E Deluxe Intel X48 (Socket 775) PCI-Express DDR2 Motherboard
- Intel Core 2 Quad Pro Q6600 "Energy Efficient SLACR 95W Edition" 2.40 GHz (1066FSB) - Retail
- Akasa AK-966 Blue Aurora (Intel LGA 775)
- Samsung SpinPoint F1 1TB SATA-II 32MB Cache - OEM (HD103UJ).
- Geil 2x1GB DDR2 Memory
- PNY GeForce 8800 GT 512Mb GDDR3
What would the minimum amount of power supply be?

Its difficult to work out exact minimum, but if youre after a recomendation for a PSU, I'd suggest this PC Power & Cooling one, very good and only £43, and it will be adequate for your system

If your overclocking i would suggest at least a decent 550W

If your not then the above poster's suggestion should cut it but without a lot of negotiation for future upgrades.

470 will more than do his system, whether he's overclocking or not, the total power draw is likely 250-300Watts, so stop talking gibberish

Hi mate, dont think that should draw anywhere over 300-350watts, power supplies work more efficient when using 80% or less load, so i recomend this one, which is also ready to take on any future upgrades.

and is modular

you might be interested in this thread, it just goes to show how little power is needed for even the beefiest of setups.

Mind you I would still opt for a decent brand with a lowish wattage ~400W thereabouts just to make sure you've got a bit of head room for any upgrades

The original question was 'what would the minimum power supply be?', and the answer is given above - probably in the region of 350w (trouble-free, no overheats, no dropped voltages). I don't see the point of putting the minimum PSU in your rig though, extra watts don't cost that much and give you more flexibility, so I'd go with the first answer and stick a 500-550 PSU in.
