Hello,

Given that every system is so item specific, especially when selecting a PSU, I've decided to create my own thread. Current rig: http://powerspec.com/systems/system_specs.phtml?selection=G188

CPU: i5-3570k (planning to OC)
CPU Cooling: stock (upgrading to CRYORIG H7)
OS: Windows 8
MOBO: ASRock Z77 Extreme4
RAM: 8 GB (2x 4GB DDR3/1333 - may also OC?)
HD: WD 2TB 7200 RPM
SSD: 120 GB (upgrading to 500GB SSD)
GPU: Zotac GeForce GTX 660ti (upgrading to GTX 1070-haven't settled on brand/model yet)
PSU: 500W Allied SL-8500BTX (need to pick upgrade)
Case: Powerspec Midsize Tower w/ top-mounted PSU config (see link above)
Budget: Within reason - hoping < $100? I believe you get what you pay for, and I don't mind paying extra for quality.

I bought this Powerspec rig a few years back, primarily for education purposes, but now I'm upgrading a few components to give it some gaming punch and hopefully a few more years of reliability. This will be my first OC, and I realize that with my case & aftermarket H7 cooler, I still won't have an icebox, so I don't plan on using too much more power. I pretty much plan on stepping up voltage until my temps take their first big jump, then backing off.

I could potentially SLI the 1070 in the future, so I would like to have that capability at least. From my limited understanding, it's simply more efficient to have extra wattage in a PSU, and NOT to use it, so I've been advised to look for 600-650W range. I would also like something that provides it's own cables (probably standard?), as I definitely need to rework my case's cable management --- so new longer cables = better; non-rainbow would be aesthetically nice, but not necessary. From reviews and other forum threads I've read, the EVGA SuperNOVA's and Corsair's are excellent brands to look at, but there is simply so much that I don't know/understand about the different models, their specs, and which will suit my needs better; which is hopefully where you can help provide some insight? Thank you in advance for your time & consideration.

...which is good to know, but I'm curious what the specific differences are between the P2, G2, etc. Otherwise I guess I'd simply just find the cheapest one? Thanks for your reply snurp, I was just looking for a bit more specificity/clarity, which I could then learn from in the future.

GQ is not good , GS and PS are good made by SEASONIC , B2 , G2 , P2 are good made by Super Flower.

Seasonic and Super Flower are some of the best in the market.

Another good one is the RMx series from Corsair made by CWT.

Best on the market in my opinion is the RMx and RMi Corsair lineups.

"EVGA has an extensive PSU portfolio that consists of 11 distinct families including T2, P2, G2, B2, PS, GS, G1, GQ, B1, N1 and W1. The T2, P2, G2 and B2 lines are manufactured by Super Flower; the PS and GS by Seasonic; the G1, GQ by FSP; and the lower-end B1, W1 and N1 by HEC.

As you can see, EVGA works with multiple OEMs, which allows the company to remain flexible and effectively address market demands. For example, Super Flower and Seasonic are pretty expensive manufacturers, so they aren't great choices when it comes to mainstream products. On the other hand, HEC's mainstream platforms offer decent performance for their cost. And for its mid-range PSUs, EVGA chose to go with FSP."


So basically Superflower and Seasonic are the best and most reliable OEMs, hence the product lines I recommended from EVGA

Okay, so basically Seasonic/Super Flower have an OEM/vendor relationship with EVGA --- which is slightly confusing in that I can also directly buy a Seasonic brand PSU off the same website(s)? I'm guessing they're just a different product that EVGA didn't want to rep or mess with?

@ Blackbird: ...if so, your latter advice seems contrary to your former Corsair recommendation? Or are you simply saying that the Corsair is the best deal at the moment? No disrespect intended, as the specs and price (and "velvet freakin' bag") seem like a solid recommendation, in which I'll take no issue promptly pounding the "Add to Cart" button.

Now that my interest is piqued, I understand the broad group differences now in the PSU quality heirarchy. Just for my understanding though, what differentiates the different models if not quality? Is it simply 80 plus rating differences?

Edit: maybe I misread, or you edited. Got it now :)

BABABABABOOOOOSH. Bought it!

Then, if my wife asks me why I bought this, I'll gently but stearnly place my finger on her lips and confidently say, "Shhhh. SR-71 Blackbird from Tomshardware told me to." We'll speak no more of it, and my wife will quietly relish in her decision to marry such a steely-eyed, barrel-chested warrior of a man, whose capability in soliciting only the utmost sage advice in providing the very best for his family's home (and mild gaming addiction) for many years to come.

...I'm really hoping you don't work for Corsair? :na:

@snurp, you helped a lot here too, but you don't have a sig with explosions & stuff, so your advice weighed less in my opinion :p

Seriously though, thank both of you for the education. I tip my hat to you gentlemen (or ladies?), it's supremely appreciated.
