Power supply

[waqifti]

I have

core 2 quad q8200
xfx 750isli mobo
2gb corsair
4870
160 gb harddisk and a super drive

how much power supply would i need is 400 watt enough

which is better silverstone 500..coolermaster 600..or corsair 550

which company is better in all of these

 

[obsidian86]

corsair 550
antec 550
seasonic 520
all good options

Here's ATI's power recommendation

500 Watt or greater power supply with two 75W 6-pin PCI Express® power connectors recommended (600 Watt and four 6-pin connectors for ATI CrossFireX™ technology in dual mode)

You could get away with a 400cx, but doesn't have enough 6 pins for you 4870, so you would need the corsair 550vx which has the two 6 pins. Also it is the best out of the three choices. Coolermaster PSU;s are junk and silverstone varies alot from model to model.

The Corsair is by far the best of the three. It will power just about any CPU and single GPU card except, perhaps, a GTX480.

Get that Corsair PSU, it's the best from your options above...

I get what u. Say butt are
double 12v rails better than one

I get what u. Say butt are
double 12v rails better than one

the total combined power output is the most important. keep in mind that for example a psu has 2 12v rails at 20amps each that deosnt mean it can do 40amps. the rails is (imo) just marketing hype. a good single rail psu and a good multirail psu will do the same thing. i prefer single railers...

Silverstone has a lot of 500W models. Which one did you buy?.

oops sorry excuse my guinea pig

 

[Ndx]

I recomend you to buy powerfulier psu (650w - 700w compucase or chieftech). It's good then yo want upgrade pc.

 

[wa1]

Yes, which model?

That's my PSU and running HD4850 just fine.
For HD4870? Yes, it would provides enough power...

500 wat sst-st50f-es

500 wat sst-st50f-es

It's a decent PSU from Sirtec. Its +12V power is on a single 34A line that provides a maximum of 408W and it presents one 6-pin and another (6+2)-pin PCIe connectors. The capacitors are Taiwanese by Teapo rated at 105ºC. The voltage regulation and ripple/noise supression is good. It runs quietly due to its 120mm sleeve bearing Globe Fan S1202512L fan (2000 RPM, 67.3 CFM and 34 dbA at full load).
As I have said before, it is a decent unit which is able to provide enough power to handle your system.

Because although CM makes some really nice cases, most of their PSU's have been two steps above junk.

And chief-tec is not much better.
