Yes. You can buy as big of a PSU as you want

Added on December 4, 2011, 7:57 pmArguably even 550W is more than enough. However I generally recommend customer to take TX series, and 650W.

Opps forgot to mention that i need psu that is the same size like the existing or it won't fit.

check the specs 1st ( length, height etc) then look for the psu with the same specs with ur current psu

Get the FSP Hexa 500W. Best psu for the money at that range

Corsair AX1200/Antec Quattro 1200W high end rig.
SliverStone Strider ST1500 for extreme

Guys I have some question here. Recently I watched a video that talks about power consumption. The video is here:

Well Linus put in all high end parts in and the end Wattage usage is only 500~600W under full load. So my question is why do we need PSU that is rated above 800~1200W?

anyone or fren tried huntkey jumper 550 ?? any suggestion?

Corsair / Seasonic / Antec is the way to go.

Xigmatek NRP-PC-702 700W [80+ Bronze]
Cooler Master GX 650W [80+ Bronze]
Seasonic S12II 620W [80+ Bronze]

All three seems to have similar pricing by average, but which one is better bang for the buck? Or maybe lower RMA rate?

I have did some research and all of them more or less have very good output and low voltage ripple in tests.

Might be building a new rig that will be used mainly for work (photo and video editing), some light gaming with a midrange graphics card (HD68xx/HD78xx class), and CPU overclocking for benching purpose only. Will not run overclocked setup for daily use.

Seasonic S12II 620W.

hello

can help me to choose a good and reliable PSU for this spec :

i7 2600k @ 4ghz
cm 212 +
xfire 6970 hd
and 1.5v 8gb ram

my budget arrnd rm600.... i abit pening on psu choice

FSP Aurum 80+ Gold 700 Watts = RM479 (5 years warranty) IdealTech
Corsair TX750M 80+ Bronze = RM439 IdealTech

thx allot

I bought a Corsair GS600 PSU and just realised my 6950 uses both the PCIE connectors. If I want to crossfire another 6950, is there anyway of doing it or must I change PSU?

600W is not capable of handling two Gpus.

One GPU: 500-650W
Two GPUs: 850W

I just found out about the 7800 series GPU's. I think I will get a 7850. It only uses 1 6 pin connector. If I need to add Xfire, only use another pin. Plus the energy consumption on those cards are very low, even on load.

Most probably have to get a ivy bridge proc (cause it uses only little energy) to ensure the whole rig doesn't stress the PSU with Xfire 7850. I think it maybe achieveable

i only use 500w(bronze) psu..
go green man...haa..haa

Hmm.. some [buzzzzzzz] sound coming out from my PSU this morning.
Still working but wondering if this will harm my rig

CM GX series 650W

Get ur self a power regulator - voltage regulator/stabilizer

thanks bro, You mean something like this?

Is that good? or you have any other recommendation?
