Which one will be the better for my system?

Antec Three Hundred Case
Intel Core i5-750
Asus P7P55D LE
ATI Radeon HD 4850
2x2GB G.Skill Ripjaws 1600MHz
320GB Samsung F1
80GB Intel X25-M

I want to be able to overclock CPU @ about 3.8GHz

I checked several technical references. There's a minor problem with stability on the rails of the OCZ power supply. It's okay but the Corsair VX450 would be the better choice.

However, I would recommend the VX550 because of overclocking and 4850 power consumption. A high quality 500 to 550 watt power supply such as the VX550 with a single large 12 volt rail rated at 41 amps can easily power a system with any single video card made. The VX450 comes with one 75 watt, PCI-e, 6 pin, video card power connection. The VX550 comes with two 75 watt, PCI-e, 6 pin, power connections. One is actually a 6+2 pin connection which can be used as either a 6 pin or 8 pin connection. You would be prepared for a future video card upgrade.

I prefer Corsair, and it would certainly do the trick, but the OCZ would give you a little more headroom and a larger upgrade path with it's dual PCI-E connectors.

I went with the corsair vx550 for the future proofing and leave CF open as an option. Its a certified AMD CF PSU for the 4850.

But either will get the job done for your current system.

If you can wait for black friday, might be able to get the 550+ for same price as the 450.

thanks for info guys.
I'm also interested in one thing. Which of these are relatively quiet?

I'm building the silent PC so definately want to get one which is really quiet. Will one of these do, or shall I go for a different one?

They are all probably about the same noise level, if any are quieter I would say the Corsairs are slightly.

You got 3 votes for the Corsair VX550. I guess that makes mine #4.

HardwareSecrets has a great review of the Corsair 450VX. They also liked the OCZ 400SXS well enough but did not have good things to say about the OCZ 500SXS.

This OCZ PS is 700 watts with modular cables = I can't believe the price = $49.99 at tigerdirect which I really like the service and price - Excellent reviews - I recommend over Mr Egg.

With the demanding systems of today you need a minimum of 700 watts = more is better!

Good luck and keep moving forward! :bounce:

No and not always.
Ever think there might be a reason that 700 watt psu is so inexpensive ?

Thanks guys. I think I'll go for corsair 550 although it's not modular.
Let's see how will it be. :)

Delluser I can appreciate your opinion and we all have ours - OCZ makes good solid products, this one has is a bit unbelievable to me and it has $30.00 rebate with normal retail of $79.99 and even that is hard to believe with this power, modular and (3) year warranty -they want to break into the market with PS.

I still believe this average system of today needs more than 550 - 650 = must think about the future add-ons.

Keep charging!

They provide a mixed bag of good and not so good units, and typically drop pricing on units that are being discontinued for whatever reason ( usually high return rates )
They broke into the PSU market quite some time ago, I have a 6 year old Modstream 520 hanging out in a closet somewhere, still works but the fan has gotten pretty noisy.
