Hi guys. I'm looking for a new PSU that will work good with my system and won't die on me for 2 years or so. I currently have an Xilence XP500 R3 Redwing series and i want to put it in my other build and get a new one for my gaming rig. I need a good 500W PSU (if that's not enough maybe 550W or 600W) i was thinking about getting an Antec Earthwatts 500W Green but i don't like the 80mm cooler it has but is it good enough to run my system without killing it or do i need something stronger?
Specs: AMD Radeon HD 6850
AMD Phenom II X4 965 BE
MSI 870S-C45
4gb of Transcend DDR3 RAM
160gb Seagate barracuda 7200rpm
Pioneer DVD RW (ATA)

It will easily be enough. I'd even recommend Corsair CX 430 if you want to save some money:

P.S. May I ask why you need a 500w?

Because i would rather have more power than i need and also because someone wrote on the box of my radeon HD 6850 that i need a minimum 500W PSU

It doesn't need that. If you want to get more power for future SLI, I'd suggest this one then:

Hmm are you sure? I've had bad experience with Corsair PSU's. One shorted out (a 430W) on an old Pentium 4 rig which worked good after replacing the psu, the other one (500W) got its capacitors blow to pieces when i was building a PC for my friend and after 2 hours of working there was a big boom, the third one for some odd reason wouldn't even power up the machine properly (fans spin at their max speed and both green and red light were on and stayed that way until i turned the PC off. so is there something else other than corsair because i wouldn't like my PC end up having barbecue charcoal parts. and i'm not planing on crossfire or SLI since i don't have enough money for another GPU

Corsair makes one of the best power supplies in the world. They are also very affordable. I am sorry to hear that you had bad experiences with them, but it must have been bad luck.
If you aren't planning to go SLI ever, I hardly see any reason not to go with CX 430 - it's cheap, reliable and your realistic power usage will not ever go above 250-300 watts.

Well this is against my every instinct it looks like i have to risk my rig to a cheap PSU. oh well if it works then i'll just run a little stress test with furmark on both PSU's and see if the 430 is as stable as the Xilence XP500 2 year old PSU. I also don't see the reason why the CX430 has an 8pin VGA and CPU connections if its a 430W PSU. my Xilence doesn't have a single 6pin and only 2 molex connectors.

It's a quality power supply, that's why. Just because CX 430 is relatively cheap, it doesn't mean it is made out of cheap materials. I recently installed it to one PC - it really feels like a quality product. As I said, Corsair makes one of the best power supplies in the world.

I agree that they do but their PSU's just don't work for me. its like they hate me or something xD but what i'm worried about is can a 430W PSU handle a heavily overclocked and 6th core unlocked Phenom II X4 965 and a Radeon HD 6850. Btw my luck was exactly with the Xilence PSU though many people say its crap but it looks like it wasn't crap to me. I personally think that some people just have a heavy dose of luck for some unimaginable things to happen to them like one of my friends managed to run a GTX 460 on a nonamed 350W psu.

Don't get it. Chieftec isn't a quality brand. Check this for power supply ratings:

I would not with anything that's not in the list or lower than Tier 3.

That seasonic is a very decent unit as well.Your system will not draw over 300 watts of power. That phenom will consume at most 160 watts, while HD 6850 will consume around 100 watts at full load. What's left? Hard drives use around 20 watts. That's it!
good one. the radeon HD 6850 draws 144 watts when idle. on load can reach more than 200W

yo my current PSU is as good as that seasonic one and probably better than the 430W C psu. i should just buy the cheap 430W C for my other rig then.

then why does it say on the 6850 box that i need at least a 500W PSU xD

pay attention to this build and look at what power supply is running it

For people who buy power supplies like these:
http://www.tomshardware.com/reviews/low-cost-psu-pc-pow...
The HD 6850 gets power from the PCIe slot and one 6-pin connector. PCIe slot can deliver up to 75 watts of power, and 6-pin connector can deliver 75 watts too. So 150 watts is theoretical maximum that the card MAY use, but if they card was even close to that, they would not risk it and put two 6-pin connectors for maximum of 225 watts.
Also, your current power supply isn't good at all. It has 22 Amperes of power on 12v rail. The corsair CX 430 has 28 amperes and the seasonic has even more. Plus you don't have a 6-pin connector so you cannot use it for your HD 6850.

20amps on each 12v rail and has 2 12v rails so that's 40 amps and i don't have a 6pin connector but i use a 2 molex to 6pin adapter

And may i ask you will the i3 2100 bottleneck my 6850?

No it will not bottleneck.
That's not how it works. You can't add them up because then it would exceed your total PSU wattage. Usually, you can take higher out of two rails and add 10% to it. That's it. That's how it is with bad quality power supplies.

if it makes you feel any better that corsair 430w can deliver 517w (see the link) which is more power, at a better efficiency, and higher temperature then the chieftec unit you linked or the Xilence
http://www.hardwaresecrets.com/article/Corsair-CX430-V2...
FYI, the antec EA500 has plenty of power for your system and the 80mm won't be an issue since you will hardly be pushing the PSU. It's a better PSU (slightly) then the corsair 430w

like i said the xilence is doing its job as good as ever for 2 years now. and why the F is that corsair labled a 430W psu if it outputs 517W? man this is childish. i've been attacked by corsair fanboys. OK i'll buy the 430W C and if it dies on me like the 3 previous C psu's i had then its gonna meet my sledge hammer or axe.
