is 500w enough for 5770?

[xiaogray]

The system is:
Graph: ati 5770
CPU: e5300
Motherboard: ASUS P5G41TD-M PRO
Sound Card: Creative X-Fi
HDD: WD500G
DVD: LG DVD-RW

is a 500w PSU ok for this system? Thank u for answering in advance

[D1DM]

As long as it's high quality, easily. You could add another 5770.

[Pancake]

Yeah really depends on the make of the PSU more than anything else

[whobi]

What brand is it? If its corsair/antec/ etc then yes. If its unbranded its probably a 250W PSU with a different sticker on it that will explode anywhere near 500W.

[Dilz]

If its branded then yes, if not then maybe not

You need a good quality PSU, the companies I'd look out for are, corsair, coolmaster, antec and xfx. The companies are good for two reasons, great RMA and great build quality i would highly recommend them.

[qwio]

O yeah and i would avoid OCZ if I were you, I know their prices are enticingly cheap but i would keep away.

[Stasu]

really?

I would highly recommend OCZ.. Completely difference experience from me I see

why? nothing wrong with OCZ and they are not cheap???

might as well get a Seasonic since most of the innards of major vendors are Seasonic anyway.

Yes some of the OCZ's are very good. pretty much all of the Z, ZT, ZS and ZX have had very good reviews, all well made units from ether Sirtech or Great Wall
You need to do digging into a psu, to say a blanket "all psu's from X brand are good" is very wrong, many companies put out budget units that are no where near the quality of their top end units.
Also a company can still come out with a blinder every now and then.

Coolermaster esp has had duff series in the past, the original GX range where not very good, but the current GX range is actually very good.
The elite power range is passable but only just, they are still rated as peak power you need to knock about 50w off them for the continuous rating and they are still not great units, but not likely to catch fire or take hardware with them like many of the el-cheapo jobs.

In case it helps, ATI rates the 5770 as using upto 108 watts at load.

I think 500w psu is more than enough....if it's a good brand psu.(Corsair, seasonic, silverstone or antec..)

I'm running the following on a Seasonic S12 430w:

Q6600 @ 3.3ghz
2 sticks of DDR3
Radeon 5850
2 optical drives
2 hard drives
3 pci cards

Playing COD MW3 earlier, the power meter at the wall didn't exceed 270watts ish. At 80% efficiency, that's 216w.

Using OCCT PSU stress test (tests CPU, RAM and GPU together). I didn't see any higher than 414w at the wall (~330w DC at 80% efficiency).

The Seasonic S12-430w can pull 348w in total across both +12v rails. Perhaps rather close to my liking but some of that 330w DC load will hopefully be on the +3.3v and +5v rails. Also I'm not sure I'm likely to find an application that realistically stresses a system as much as OCCT does.
