500W or 600W?

[sheemone00]

Here's is the upgrade that I am planning to do:

CPU: E7200
Mobo: ASUS P5QL Pro
RAM: G.Skill DDR2-800 4GB (2x2GB)
Video: MSI R4850

I was looking at some OCZ PSUs (This and This)

For the build above, would a good 500W be sufficient? Would I be just wasting my money buying a 600W because I would only be using 1/2 of it? I'm trying to build on a budget (~400-500 USD) so if I can save some money on PSU it would be nice.

I won't be doing any heavy OCing, just upping the FSB a little bit.

Also I'm not planning to upgrade to SLI or XFire in the future.

Any tips would be greatly appreciated, thanks!

either is fine.

as far as I know the only difference between the two is the GameXstream has a blue fan. Maybe a rectifier or two are different, but otherwise pretty much exactly the same. There are better PSUs out there for the price though...IMO

What are some other good PSUs? I haven't been keeping up with the latest stuff so I'm out of the loop.

Instead of buying a 600W would a 500W be sufficient for the build in the OP?

Yes 500W would be enough.

for those prices...

The AT OC guide has this PSU Watt Calculator.

Likely 500W with good efficiency should do it. Enermax has the Pro82+ and Modu82+ that are highly recommended. Or just look for 80% efficient certified.

The GameXstreme is actually quieter than the stealth line if thats anything to you.

Any decent 350+ watt PSU will be able to power that rig.

See the rig in my sig, my kill-a-watt doesn't show it ever sucking down more than 270 watt at the wall.

My advice is to save your money and get Antec earthwatts EA430 430W
