Hey guys, i've been slowly building my first gaming PC and I needed just a bit of help on the PSU. I have bought everything but the PSU and the Case, so I am not really looking for feedback on the other parts.

This is the PSU I am considering as it is currently on sale for a pretty good price near me, but is 650w too low? Is it a good brand? Answers today would be great so I can go after work before the sale ends (if it's a good PSU) https://ca.pcpartpicker.com/part/fractal-design-power-supply-fdpsuin2b650w

This is my build so far:
CPU: AMD FX-6300 3.5GHz 6-Core
Motherboard: Asus M5A78L-M/USB3 Micro ATX AM3+
Memory: RipjawsX Series 8GB PC3-12800 Dual Channel DDR3 Kit (2 x 4GB)
Storage: Seagate Barracuda 1TB 3.5" 7200RPM
VideoCard: Gigabyte Radeon R9 270X 4GB WINDFORCE
Keyboard: Logitech K400 w/Touchpad

I don't really want to spend more than $100 on the PSU (but I will if it's going to be dangerous to my parts to go lower than that.)

Thanks guys! Good brands and a good watt recommendation are also welcome, as well as an opinion of that above PSU.

We're still talking about 2 amps or so.

At the bottom of that MSI article it links the source used for their 24 amps calculation:

R9-270X: System in IDLE = 116W * System Wattage with GPU in FULL Stress = 283W * Difference (GPU load) = 167W * Add average IDLE wattage ~10W * Subjective obtained GPU power consumption = ~ 177 Watt

- From 283w max results the recommendation: 24A and a 500W psu minimum (283w / 12v) Source: http://www.guru3d.com/articles_pages/radeon_r7_260x_r9_270x_280x_review_benchmarks,10.html

And if you follow the link you'll see that the 283w was the system idle consumption + GPU load, NOT total system load. As stated in the article "We'll be calculating the GPU power consumption here, not the total PC power consumption."

The test system used a 130w tdp CPU and they calculated the GPU at 177w under stress, that should be 307w right there (25.6 amps). Right?

To be clear guys, I'm willing to go beyond "bare minimum" if it pays off down the road :). I don't want her to just barely scrape along, I want her to work like i've just asked Da Vinci to paint a stick man lol.

I'll be playing games on the highest settings it can manage, as well as watching videos on it. I want the best bang for my buck and am totally happy to spend the money to provide this pc with as much energy as it needs. So if 550, 600 or even 700 watts is better that's good with me, I just need to know watts and prime A/V as well as good brands.

It seems I want to aim for B versions. As for brands, I see above XFX, Seasonic and EVGA as listed brands that you guys are recommending. Are there any brands that I should absolutely avoid?

This is my very first time venturing into PC's so i'm new to all the terms and parts. So any tips on what to look for and what to avoid helps!

I had two EVGA PSUs die on me. So I cant personally recommend them. Most people say Seasonic is the way to go and I agree. Also, XFX brand generally has there PSUs made by Seasonic. the XFX ones that aren't made by Seasonic are junk. You pay a premium for Seasonic but I havent ever had an issue with them and the warranty I hear is reliable.

Yeah EVGA is generally good but can be hit and miss, as are coolermaster and corsair. Antec's budget models are average but their more expensive ones are top notch.

For the most part you can follow this list:

The EVGA 750W 80+ Gold Certified Fully-Modular ATX Power Supply runs $119 here, is it still a good bang for it's buck? I see its under the tier 1 on that list, so i'm assuming it's a pretty good machine, but since it's $60 more than what I had originally budgeted I want to make sure it's going to be worth it 😉

Will that PSU allow for upgradability with other parts down the road (aka is it going to last me a long time)? How is the warranty on EVGA? The re-occurring problem that the 1 star reviews keep mentioning is that the PSU was dead on arrival, so I want to make sure it's got a good warranty and customer service on it.

Thanks guys! I appreciate that you guys are answering all my silly questions.

I can get this eVGA SuperNOVA NEX750B 750W Bronze ( http://ca.pcpartpicker.com/part/evga-power-supply-120pb0750kr ) for around 80$ refurbished at my local store, would that be any good?

But because it's a refurbished item it only has a 60 day warranty with the store, as opposed to a 1 year that new items come with.

Sorry to keep asking questions, just want to make sure i get something good. I just saw this guy also available near me, it's on sale for $100, thoughts?

You know what guys, I got my hands on a bit of extra money and I think i'm going to splurge on the EVGA 750W 80+ Gold Certified Fully-Modular ATX Power Supply. That way I have some upgradablilty, a good guaranteed output and a beautiful 10 year warranty. Plus the reviews seem very good.

I want a power supply that's going to last and I think this is a good choice, even if it is more expensive than I was anticipating.
