Hope everyone is having a great week so far. The prices on the rx 580 have made me consider upgrading the old gtx 760 and I wanted to get a new power supply at the same time. I've had the same power supply for 11 years and while it's served me well It's probably one of those things you don't want to try to keep using for more than a decade.
You'll laugh at my current power supply. It's a Thermaltake 850 modular that I had to get from Best Buy for north of $150 when one blew up during a build at a friend's house on Sunday so many years ago.
In hind sight it was a pretty amazing deal though at the time I was as salty as you could get.
I'm unable to estimate the size I need. My current specs(potentially new video card substituted): i7 4770k 2 SSD drives and 1 HDD Blu Ray drive XFX rx580 black edition 8gb 18gb system memory(stock stuff) I plug a lot of things in to the USB.
Also I'd like to hear you all weigh in on the power efficiency ratings. The gold power supplies seem to be pretty affordable but really jump up at the platinum+ level.
Requirements: fully modular warranty? long cables so I can do nice cable management and not have to stretch everything in straight lines.
Silverstone SFX 800w Titanium efficiency. Lambda A rating. ETA B rating.

You could get a seasonic prime 650W (gold). Not cheap but they are excellent and have a 12 year warranty.
Noah Morales
Pic related? $189? I'm not opposed to paying that much considering how long my current one lasted. Can you elaborate on what going from Gold to Platinum to Titanium is doing for me?
With my build listed there do you think 650w is sufficient?
Evan Myers
EVGA 650 BQ
Leo Green
650W is actually way overpowered for your PC, but they don't make a model with lower wattage. Unless you plan to use dual GPUs in the future, in which case you could go for the 750W or 850W.
Aiden Rogers
I just looked up that Silverstone and it only has a 1 year parts and labor warranty. Is that just a misprint on Newegg or am I out $189 if it kicks the bucket in 366 days?
Henry Ross
Be Quiet! brand anything. Solid German engineering. None of that Chinese rebrand crap.
Austin Green
Seasonic gold/platinum, XFX XTR series, EVGA G2 etc. You can't go wrong with any of them. Check JonnyGuru for reviews.
Bentley Mitchell
Ah good to know. Thanks man. Naw, I'm not a duel GPU kind of guy. I'll limp along with the small bit of gaming I have time to do until there is a bargain priced full replacement.
One thing I will say about the crazy expensive at the time Thermaltake is that years later I was able to buy different modular cables off their website for a new pin GPU plug I needed. 7 years later and they still had a new cable for their old modular model.
From what I can gather it seems like Seasonic and EVGA have the best reps right now on power supplies.
Any info on the difference in efficiency ratings? There are some info guides online about it but it's all half marketing spin on some of those sites. At some pricepoint am I paying just to have Japanese components and not Chinese?
>750-850W for dual GPUs in 2017 holy shit go and look at the fucking power draw on new cards you dumbass
William Wood
Maybe you should take your own advice.
Easton Reyes
list the actual power draw for each component you're thinking about, mr smartypants.
Jace Barnes
Didn't realize there were threads for buying guides. This is a pretty slow board though.
So an rx580 and 4770k need more than 650? Also, being polite doesn't cost anything user.
All their components are made in Germany? I went to their site and they claim they manufacture in Germany but are their PSUs components all sourced from Germany? And I see they aren't fully modular. If the quality is there i'd consider semi modular though.
Owen Carter
>idiots suggesting over 500w bronze/gold in the current year
you only embarrass yourself
Luke Ortiz
>So an rx580 and 4770k need more than 650? just throw your PC out the window and go back to school and learn some basic reading comprehension

I see someone got meme'd into buying a 1kW psu for his shitty pc. Anyway: tomshardware.com/reviews/amd-radeon-rx-580-review,5020-6.html Most modern cards are still well below 250W each at absolute maximum load (torture loop). So unless you're running a ridiculous vCore on your cpu and then decide to run a torture test that puts max load on cpu + GPUs you're not going to get above 750W load with most GPUs even in this scenario. In most realistic load scenarios you're never gonna see load even near 750W though unless you still mine bitcoins in 2017 on your mom's power bill. But OK maybe you do want to do that, in which case buy the 850w.
Joseph Garcia
Cmon son, not everything is hyper low wattage draw like 1050ti or 550. Aftermarket 1080tis have 320w power targets, sli of them conservatively would then be 640w. A highly Overclocked r7 1800x or 7700k will suck down another 160w easily at full tilt, so it's not a stretch to say 750 or 850w power supplies or even higher have a strong place in the market still. The trend towards low power doesn't mean the death of high power draw parts
Wyatt Smith
PSUs don't really matter. If you want a modular PSU then get it. Just make sure you choose the right wattage with some overhead
Aaron Carter
Just get the $20 EVGA 450w PSU. It'll be fine for a single GPU.
Jose Hernandez
are you fucking retarded? im saying you dont even need 750W for dual GPUs these days.

I have no technical basis for my opinion but my gut tells me that I should buy as high of quality as I can afford on a part that, if fails spectacularly, can take out much more expensive components in my computer. Am I on the right track with this thinking?
jeez man, just give it a rest. No one is taking your bait and all you're accomplishing is making yourself look like a social train wreck. I hope your week/life goes better man and you're not so angry and feel like lashing out at strangers on a board.
Thank you to everyone for this great feedback even with me making a dedicated thread for it. Good info all around. That Jonnyguru site is really cool when he breaks open the PSUs and critiques the construction and components. Would have never come across it on my own.
This one fits my budget and looks pretty good. Thoughts? Is it worth extra money for a Titanium rated model? >Seasonic Flagship Prime Series SSR-750PD 750W
That basically corroborates my claims, pulling about 300w on the founders edition which hits thermal limits and throttles more aggressively than the titanic aftermarket cards.
Cooper Ward
that's total system consumption
Lincoln Myers
No you didn't say that user. Maybe you're the problem if you can't even type a coherent sentence before raging.
Titanium is a waste of money currently, get gold or maybe a platinum model at most. The main difference between the models is efficiency and you'll probably never recoup the extra cost with the money you'll save on power. They're all good quality.
Christian Jenkins
>No you didn't say that user. it was obviously implied, you retarded faggot
Adam Foster

Alexander White
So, does anyone think SFX will start replacing ATX power supplies even in larger cases, allowing for more creative layouts?
Joseph Thomas
do you know how to read basic english?
Samuel Cox
>I have no technical basis for my opinion but my gut tells me that I should buy as high of quality as I can afford on a part that, if fails spectacularly, can take out much more expensive components in my computer. Am I on the right track with this thinking? Of course you are. If the processor is the brain of your computer, the power supply is the heart. Without a good one it can die and take other components with it. And unlike other parts, power supplies can come with 10+ years of warranty and will be 90-100% compatible with whatever you buy during that time.
My recommendation is to get a EVGA G2 or G3
Benjamin Williams
daily reminder anything more than 400w is a waste of money
And? Add a second card on there and it's a tad close for breathing room, without taking Overclock into account either.
Andrew Adams
buying used power supplies y/n??
people buy a lot of used power bricks for laptops that work fine, also oem psus.
Anthony Allen
I would say no, that is not a good idea. Unless you can get confirmation that the warranty can be transferred across owners (ie. Not tied to some registered account on the manufacturers website) and all the documentation required for that warranty is also provided, I would not even consider it.
That's the last part you want failing, as it could destroy your entire system.
Alexander Green
Most modern PSUs have the highest efficiency when under 50-60% load. So in order to save the most on electricity costs, calculate your system's expected power draw and multiply that by 1.8 or so.
