Just like the title says, I was hoping somebody could help me find a cheap but RELIABLE, trusted, clean power psu that is around 600 watts. The more the better.

Help?

What are the other components in the system like the motherboard, graphics card(s), number of hard disk drives, optical drives, etc.?

^What ko said. You may be able to go lower in wattage. Don't go for cheap on the PSU; that Corsair looks good.

"cheap" and "reliable" are not to be used in the same sentence when it comes to psu's. You can get PSU's that are good value for money from Antec, corsair or OCZ that are generally reliable.

I've got the

Asus P8P67 Pro Motherboard.

Intel i5 2500k 3.3 ghz

Azza CSAZ Solano 1000 Full Tower

ATI Radeon 6970

8 gb DDR3 1600mhz RAM

64 gb boot SSD

1 TB 7200 rpm HDD

Windows 7 OEM

and just a DVD drive..

The guy at Micro Center said a 600 would work just fine. However, being a
first time builder, all the required connections and such kind of confuse me.

I know i need an 8 pin connector for the 6970 and i think all of the fans in the case
need molex connections..

Does that sound right?

OK. Now we have something to work with.

Most 600 watt PSU's will have both a 6 pin and an 8 pin PCIe power cable or two 8 pin connectors. Dirty little secret: even if the PSU has two 6 pin connectors, don't worry. Just use them. A 6 pin connector has 3 hot wires (yellow 12 volt lines) and 3 black ground lines. An 8 pin connector has 3 hot wires and 5 ground wires. That means that it cannot carry more current than the 6 pin cable.

Warning: you shouldn't be able to interchange the CPU power and PCIe power cables. (But it's been known to happen.) If you do, you will short 12 volts directly to ground.

For some help with your first build:

And although this primarily a troubleshooting thread, the first part contains a checklist that will catch most noob mistakes:

For a single Radeon HD 6970 graphics card system AMD recommends a 550 Watt or greater power supply unit with a minimum combined +12 Volt rail current rating of 42 Amps or greater and with at least one 8-pin PCI Express supplementary power connector and one 6-pin PCI Express supplementary power connector.

It is more important to meet the minimum combined +12 Volt rail current rating requirement than the power supply's wattage requirement.

There are very few 550 Watt and 600 Watt power supplies that have 42 Amps or greater on their combined +12 Volt rails.

It's easier to find 620 Watt or 650 Watt power supplies that meet the requirement.

I would suggest getting this PSU. I am using this PSU in 2 of my folding rigs and it has been very solid, and on par with corsair TX850 that is also used in one of the folding computers.

Not really the TX850 has a SINGLE rail @70Amps. That has like 6 12V rails!

Corsair rated at 50c
Kingwin rated at 25c

Corsair 5 year warranty
Kingwin 1 year warranty

Corsair 80+ certified
Kingwin claims 80+

The single rail vs. multi rail thing doesn't concern me

It may be a decent budget psu, but here would have to be a hell of alot of handicapping going on for the Kingwin to be anywhere close to " on par " with the Corsair.
