Was looking at the manual it say's
ATX Power 12v , 2.0
24-pin
EATXPWR , 8-pin
EATX 12v
So I guess I'm looking for a ATX 12v w/ 24-pin + 8 power supply {is this correct}?
I would like to get a 80 Plus GOLD PSU, 750W or better any idea on a good PSU thanks!

Most psus in a decently high range (520w+) will come with a 20+4 pin mobo, 4+4 and/or 8 pin eat with either 2 or 4 pcie and a range of molex and Sata, floppy connectors.

This is normal, especially on psus designed for gaming purposes, not servers.

As far as the motherboard goes, its got nothing to do with what size psu you run. The gpu is everything. You can run any pc off a 300w psu all day long with no hiccups. Add in a power hungry dedicated psu, and the game changes drastically. Without knowing exactly what gpu you plan on, choosing a psu of adequate size is impossible.

The 80+ ratings are a voluntary certificate, not a standard by any means. All it says is that at 20%/50%/100% load on the psu it will maintain 80%+ efficiency. Bronze is higher, @83%, gold higher still, up to titanium. The offshoot of all that is that the better the rating, usually, the better the quality of build and components. Supposedly, that is. 2 things to think about. Some manufacturers have high enough standards that the quality series psu they build tend to actually live up to the rating they say it is. There are also some of the more disreputable companies who will throw "Gold" at you in an effort to mislead you into thinking the psu is better than it actually is.

The psu is the single most important component of any in a pc. It is directly connected to everything that runs, moves or thinks, any cpu will do, any gpu or none will do, any mobo or drive will do, but a bad quality psu, with lousy voltage outputs and amperage regulation and seriously choppy ripple will guaranteed destroy any hope of happiness with multiple errors, blackouts, shutdowns, bluescreens etc, not to mention simply catching fire (literally, on fire, it was even video recorded with multiple brand new units that never got to 100% load before bursting into flames). Quality, quality, quality. Go cheap and you'll end up replacing something sooner or later, and that means anything from the mobo to cpu to gpu usually.

so as long as it reads 1 x 24 Pin ATX or 1x 20+4 Pin ATX
2 x 4 + 4 Pin EPS12v or 1x 8 pin EPS 12v will work with the motherboard ?

They will all have those. Standard issue for any ATX psu is 20+4 pin and 4 pin EPS. The better grade psus will give options such as a 4+4 or 8pin EPS, 6+2pin pcie etc. A psu size depends entirely on the size of the gpu. You will not have the correct connectors for a high end gpu on a low power psu for a reason. The only need for 8pjn eps is overclocking. It's extra power and therefore stability under high stress loads. For a locked psu, you won't need all that extra, so a 4pin EPS is enough. You can use a 4pin EPS in an 8pin slot, or if the psu has 4+4 or 8pin use them instead. Just match the psu to the gpu. You won't have the correct connectors on a 430w psu for a r9 290 for example, for just that reason. It'll require 2x 6+2 or 8pin pcie.

So yes, the ATX psu will cover your needs, just get one large enough to cover the gpu, and the rest will cover itself.

But the info for the M5A99X it says that it needs 1 x 24-pin EATX Power connector(s)
1 x 8-pin ATX 12V Power connector(s) {got to have both connected for the MOBO to boot}
So I need to get a PSU that has a 20 +4 or 24 12v pin {for the mother board} and a 4+4 or 8 12v pin EPS {for the CPU}
Just trying to pick the right PSU for this mother board all the cases I ever bought always had a PSU in it

Yes. That is correct. Size of the psu will be determined by the video card. Absolutely no point in buying a 350w if the video card needs 550w.No point in buying an 850w if all you use is on-board graphics. All of the above will have the connectors you need, all ATX power supplies do.

That would be better, if for no other reason than upgrade to something along the lines of an r9 280, which is what op would need to play any of the later games with decent framerates even at high settings. A 750ti even suffers on mediocre settings for something as simple as elder scroll online. And that gpu upgrade would be well worth the extra $40

Yup, R9 280 is a solid card for 1080P. Overclock it and you have a 280X.

Yeah, well almost a 280x anyways. I have found that the non-modular versions tend to be more reliable, have less driver issues and only rarely suffer coil whine which have a tendency to be prevalent in the X series. Dunno if anyone else sees this. Among recommended brands are Sapphire, Asus and the MSI twin frozr line.

I end up getting a EVGA SuperNOVA G2-850 watt! , Now about the R9 280 that is a bit pricey how good are the R9 270 , I don't play much games but my son does and wife likes to play those puzzle games , me I stream movies on-line.

Congratulations on an absolutely superb psu. The 850w version is more than strong enough to power all but the 2 most powerful gpus on the market. The 270 is a decent card, about in the middle as far as performance goes. Unless your son is into the most intensive graphics games at the highest settings, it'll be fine. Price is not surprising. The gpu has a tendency to be the single most expensive component of any pc where gaming is involved.

Yep, the X is the fully empowered version. If a card has 4 chips on it, the X version would have access to all 4 chips, the non-X would have access to only 3, other than that, the architecture of the 2 versions is identical, the guts, with cosmetics being sometimes different, 1 has 3 fans, the other 2, 1 has a graphic decal, the other is plain etc. Some cards are so well built that the non-X version can almost equal the stock X version with some overclocking, and many do that just to save some $, but even maxed out OC on a non-X will be anything relatively close in performance to a X with OC, so you'd need to move up in architecture. To beat the performance of a 270X Superclocked, you'd need a 280 etc.

Honestly, for plain-Jane 1080p standard 60Hz monitor, the r9 280 is as good as it gets. Even with its moderate price tag, value wise it has no equal. It'll handle anything you can throw at it and still get playable speed at least on high detail settings if not very high or ultimate. Every gpu made has its downers about it, for some it's the price/performance ratio, for some it's the need for uber power, for some it's excessive heat and the 280 suffers from none of those. As far as complaints go, the r9 280 in general, is on the short list.

Came across a XFX Doouble D R9 280A-TDFD {827MHz} with a Lifetime warranty upon registration ? I've never had a video card go wrong as long as I can remember since I had a 486 computer. I've been looking at a MSI R9 280 with a Core Clock 933 MHz {$199. with a $20. Rebate} any good?
I also notice that the higher the core clock speed the more it coast , like if it's over a 1000MHz it will coast over $200. The 280x would be more.
