M4a78lt-M Motherboard and GTX 660 Palit Incompatibility?

[JimSampson]

Hello, First timer just wanted a simple answer, unless there is more to it .

Basically this is my current set-up/rig.

Mobo: M4a78lt-m Asus

Cpu: Phenom II x4 965 BE O/C to 3.8ghz stable.

Cpu cooler: stock AMD one.

GPU: Radeon HD Sapphire 7750 1gb GDDR5.

PSU: 450w Raidmax stock anti-surge (definetly will upgrade to powercool 750w one from amazon)

Ram: 4gb Samsung 1333

Now to my question. - I want to know if i did upgrade my rig, the GPu and PSu would hte new ones work with my Motherboard, because im not sure about power connectors.

The ones i want to upgrade are to a GTX 660 Palit - http://www.overclock.co.uk/product/Palit-2048MB-GDDR5-GeForce-GTX-660-OC-DP-2xDVI-HDMI-PCI-E-Retail_44635.html

And this PSU - http://www.amazon.co.uk/Powercool-750W-Dual-V2-2-Efficiency/dp/B00647MS3K/ref=sr_1_6?ie=UTF8&qid=1358182314&sr=8-6

What do you think, good choice, will it work and is this the best option and cheapest, or are there cheaper alternatives, i prefer to keep that gtx 660 btw it looks solid from reviews i read.

I reckon you'll be OK to just slap a 660 in there and be done.

With the current PSU?

If so fantastic, Thank you very much

It's only a 140w GPU, you'll be fine.

If your current PSU is the RAIDMAX RX-450K with a maximum +12V current rating of 21 Amps and with no PCIe power connectors I wouldn't recommend it.

GeForce GTX 660 (non-Ti)
Minimum of a 450 Watt power supply. (Minimum recommended power supply with +12 Volt current rating of 24 Amps.)
