Windows 7: Just added a E8600 3.33 and want to overclock

And there`s absolutely no reason to get the Corsair HX650


Bearing in mind, I just ordered the Corsair Vengeance C70, with a lot of fans.

Also then why are the newer cards needing 2 plugs ?

Not unless you wanted to have like two overclocked GTX 680s or two overclocked 7970s with a very heavily overclocked 3770K. I'm not talking about heavily increasing the voltage of these video cards, but still.

Even then, I would not get the HX650 because it only has 2 x 6+2-pin PCI-E cables as I mentioned before.

This one does, it costs less, and it's a high-end modular PSU just like the HX650:

On page 4 of the PDF below, it shows that there is 1 x PCI-E cable that has 2 x PCI-E connectors on it.

I`m only going double graphics cards at the most ever.
Check my eddit above.

I don`t read that anywhere on page 4 but page 7 states the 650 has a quanity of 2 pcie cable/connectors that`s confusing.

Corsair Vengeance Series C70 CC-9011016-WW Mid-Tower Case - Steel, Carry Handles, 3 x 120mm Fans, USB 3.0, 8 Expansion Slots, 3 x 5.25 Bays, 6 x 3.5/2.5 Hard Drive Bay, Black at TigerDirect.com

So that they get all the power that they need. It doesn't mean that they require hundreds of watts or something like that. I mean, look at this for example:

ASUS Radeon HD 7970 Crossfire review - Hardware setup | Power consumption

With two 7970s under full load in their system, their PSU pulled 567W from the wall outlet. Their CPU was idling, so if you had an i5-3570K overclocked to 5 GHz and under full load at the same time, then it would pull 150W in addition to that making it 717W being pulled from the wall outlet. So if the PSU were 90% efficient while pulling 717W from the wall outlet, then the system would be pulling 645w from the PSU. However, this is an unrealistically high power draw because I'm saying that the 7970s and the 3570K are under full load at the same time. Plus, it's not exactly easy to get the 3570K to 5 GHz. A more realistic overclock is about 4.5 to 4.7 GHz which results in about 125W at the most.

So, the more realistic power draw is going to happen while gaming. For the above, it would be about 575W to maybe 600W being pulled from the PSU at the most.

Then there are the GTX 680s which pull less power:

GeForce GTX 680 SLI review - Power Consumption

With two GTX 680s under full load in their system, their PSU pulled 473W from the wall outlet. As before, their CPU was idling so I'll add 150W again just like last time for the 3570K at 5 GHz and under full load. So that makes the PSU pulling 623W from the wall outlet. So if the PSU is 90% efficient while pulling 623W from the wall outlet, then the system is pulling 560W from the PSU. Again though, this is an unrealistically high power draw for the same reasons: simultaneous full load between the 680s and the 3570K, and the 3570k is at 5 GHz when 4.5 to 4.7 GHz is more realistic.

The actual gaming power draw would be closer to about 475 to 500W being pulled from the PSU at the most.
