Advice needed on power of PSU???

Notorious Lee · 8 Apr 2007 at 20:33

Hi,

I am currently in the process of putting a kit list together to build my first PC & I am in need of some advice on what PSU I will need to power the following components: -

1 x Asus P5N32-E SLI NF680i SLI, S 775, PCI-E (x16), DDR2 533/667/800, SATA II, SATA RAID, ATX Motherboard

1 x Intel Core 2 Quadro Extreme Edition QX6700 CPU

1 x EVGA GeForce 8800 GTX KO ACS3 SILENT 768MB GDDR3 HDTV/Dual DVI (PCI-Express) - Retail Graphics card

1 x OCZ 2GB (2 x 1GB) PC2-9200 1150 MHz Watercooled Dual Channel DDR2
memory

Will I need a 1000 watt psu or will I get away with a samller unit?

Thanks.

Nah 500w+ will do

Something from Corsair, Antec, Tagan or Seasonic will do nicely

Thanks for the advice Will but OcUK recommends a minimum of 550 watts for the 8800GTX graphics card alone.

I am now really confused because another guy on a different forum also recommended a 480 watt PSU would do the trick.

Corsair HX 620W would be my choice.

ocz 700w, or the new antec 650w for me

The Corsair 620 would be my minimum TBH, have a look also at the Enermax range.

the corsair 620 would power that with ample room to spare

The HX620W will power that easily- the 520W would probably do it fine but I'd go for the 620W anyway. On another note, buy yourself a sensible processor- there's no point wasting money on QX6700- I would have thought an E6600 would be more than fine

Hi

I have my entire rig running on a 600W tagan with no strain or instability what so ever, in fact I have had it running on a 480w tagan easily and even a budget 350w from an old computer case ran the rig although it wasnt happy when under load.

To be honest with you as long as you get a decent, named and stable powersupply, some from tagan, corsair etc you will be fine, personally id go for a tagan dual engine 600w or above or a corsair 620.

That system would run off 500W but I would advise going with something like the Antec 650W, Corsair 620W if you want head-room for overclocking CPU, memory GPU etc.
