Just added a E8600 3.33 and want to overclock

Ya but I wanna spend more money then that and I`ll be putting in a 660 gtx soon and and ssd, so wouldn`t you think I should get the Corsar HX750?

If the GTX 660 is replacing the two 9600 GTs, then you could power your system with this:

I'm serious.

Why would you need a PSU like the HX750? Or for that matter, why spend more when you can spend less and put that money towards something else? Or, put it towards bills or groceries.

Actually, why do you want to spend more than that? I don't understand why anyone would want to spend more when they can spend less without having to make any compromises whatsoever. If you're worried about the quality of the Rosewill Capstone Series, then here's a professional review of one of them (it just happens to be the 750W version):

Edit: Not to rain on your parade, but the E8600 will bottleneck the GTX 660.

But thought 550 wat was noy powerful enough but you think a 360 wat psu unit is ?

The 360W SeaSonic G Series is rated based on its continuous rating. It can continuously deliver 360W 24/7 if it's ever needed, even all the way up to an internal PSU temperature of 50°C. Its +12V capacity is 360W, matching the +12V capacity of the 550 Ultra LSP. However, the 550W Ultra LSP is a low-quality unit and is better to think of it as a low-quality 400W PSU.

I know how this sounds, but hear me out. Here's a review of a GTX 660 and it shows the power consumption:

MSI GeForce GTX 660 TwinFrozr III review - Graphics card power consumption

With one GTX 660 under full load in their system, their PSU pulled 230W from the wall outlet. Their CPU was idling, so I have to add 65W for an E8600 under full load. That makes the PSU pulling 295W from the wall outlet. So if the PSU is 90% efficient while pulling 295W from the wall outlet, then the system is pulling 265W from the PSU. That would make a PSU like the 360W SeaSonic G Series look at you and go "Really? I'm bored." To take it further, this is an unrealistic power draw because I'm talking about both the 660 and the E8600 under full load at the same time. Your actual gaming power draw will be closer to about 225-250W at the most.

I wanted to recommend a PSU with a lower power capacity just to make a point, but the 360W G Series is just about the best PSU in the 300-400W range.

The 550W Ultra LSP is pretty much on the other end of the spectrum. Even though it has the same +12V capacity of 360W and even though I could basically call it a 400W PSU, it's nowhere near what the 360W G Series is. They're in totally different worlds.

Edit: A 500W peak-rated PSU will have a +12V capacity of about 350W, +/- 10W.

So, I'm just showing you that it makes no sense to get a PSU like the HX650. To power any modern system with one modern video card, all that's needed is a quality-made 400-450W PSU to be in the perfect "sweet spot".

If you want to overclock the E8600 after getting a new PSU, then maybe step the PSU up to a 450W. However, the lowest-priced 450W power supply at Newegg is the 450W Rosewill CAPSTONE Modular Cable Version Series for $85.98 after shipping:

Rosewill CAPSTONE Series CAPSTONE-450-M 450W ATX12V v2.31 & EPS12V v2.92 SLI Ready CrossFire Ready 80 PLUS GOLD Certified Modular Active PFC Power Supply - Newegg.com

At that price, you may as well get the 550W SeaSonic G Series for $89.99 shipped:

SeaSonic G Series SSR-550RM 550W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS GOLD Certified Modular Active PFC Power Supply - Newegg.com

The 450W unit here would put you in the sweet spot in terms of getting the highest average efficiency, especially with overclocking. We are definitely not looking at stressing the PSU with this capacity and this quality.

There's absolutely no need to spend more, but it's still your money.

I had to edit my bigger post above because it said "their PSU pulled 230W from the PSU". I meant "their PSU pulled 230W from the wall outlet".

So you would have no problem putting the seasonic in my rig as it is now. And doing a slight overclock on the cpu to 3.6 would be no problem ?

A slight overclock? No problem. If you wanted like 4.33 GHz (1 GHz overclock), then I think a quality-made 450W PSU would be better. That would also set you up to power any modern system with any single modern video card in it (such as today's GTX 680 and HD 7970).

Again though, the Rosewill 450-M is $85.98 after shipping from Newegg. The 550W SeaSonic G Series is only $4.01 more at $89.99 shipped, so you would be better off getting that instead. That way, you'd be pretty much set for life. I mean, each new generation of GPUs and CPUs requires less power than the previous, so the only time you'd have to replace the PSU is if it were to die for some reason - or if a new kind of PSU is invented that makes today's PSUs completely incompatible with tomorrow's computers.
