PSUs!

Toothless · Nov 7, 2014

So a buddy of mine and his brother are both getting upgrades. Here's the list.

FX-6300 (Both)

Gigabyte GA-990FXA-UD3 and a ASUS M5A97 R2.0 970.

MSI GTX 770 (Both)

8GB DDR3 G.Skill (Two 4GB sticks each)

He's on a budget and he needs something that'll handle SLI for the future with the 770's.

Any advice?

kronic1 · Nov 7, 2014

well you will want a 750w at a min if you plan to run 2 770s, there around 230 watts each i think, if your after good cheep power supply's iv had an awesome run with these, http://www.aywun.com/ProductDetails.asp?ID=139
850 watts 2x 30amp rails for Gpus and 2x 20 amp rails for Cpu and Drives etc, more than enough, iv even run my 290 crossfire setup on it for a while
and mined on it for ages still haven't broken it

Who makes those Aywun units?

First of all, 750+W? Really? 650W is plenty for what he needs. I know, I know... Headroom etc. A well-engineered PSU already has headroom beyond it's rated max, so that it lasts at least as long as its warranty when you run it at 100% 24/7. Not that I encourage such a usage scenario, but 770 SLI + FX6300 will hardly go over 500W under extreme loads. Regular usage (i.e. gaming) won't see much over 400W. Feel free to test it yourself.

Secondly, Aywun? Seriously? If there ever was a shady company... What's wrong with all the usually recommended stuff? Doesn't have over-the-top tacky robots on the box?

Anyway, if you're on a tight budget but want quality, currently Rosewill offers the best bang for the buck in the sub-$80 bracket, and by far.

The Capstone-750 is a great choice, and if you need/prefer modularity, the Capstone-650M is great. The price is ridiculous, even more so if you can be arsed to fill out the rebate forms and send them in.

Again, don't really need 750W but they don't offer the non-modular Capstone below that.

I'll check them out and talk to my buddy.

Tried and tested around 10 of those 850w aywuns mining mate, personaly thrashed the ass off them , they have outlasted Enermax Corsair and Sesonic power supplys theres nothing wrong with them, strong as plenty of headroom will power up 2 2x 290s Ocd at push and you can get them for cheap like $120 nzd im Currently running a Fsp 1200w witch i love but it did cost me $300nzd
you want the biggest and best Quality power supply you can afford as its the core of any good system and the least changed component if u choose the right one
i dunno about those capstones never used them personaly so cant comment ,but i still have 8 850s powering Antman s3s 1,in my server and i killed one trying to run to many knc modules on it at a time ( my bad )

A quality 750 watt PSU just make sure it has two 8 pin and two 6 pin connectors. imo it would be best to steer clear of the Aywun PSU. They're not even listed here

http://www.tomshardware.com/reviews/power-supply-oem-manufacturer,2913-4.html

and there's some pretty obscure PSUs listed in that roundup.

Why the GTX 770? There are better deals out there.

I wouldn't run that Aywun unit if you gave it to me

I was going to have him get the same Raidmax as me but it's only a 530w (Though there are higher wattage Raidmax PSUs)

I kept leaning to Corsair and Seasonic but I just wasn't completely sure on which would suit him best.

McSteel · Nov 8, 2014

Anyone buying Raidmax willingly and knowingly deserve everything they got coming to them for doing so.

I didn't have much of a choice but it runs like a champ.

I don't know about that statement. I have 2 crunching rigs on Raidmax psus and they have being doing great for over a year now.

Antec is the right psu for every build!

EpicShweetness · Nov 25, 2014

A PSU is a PSU personally as long as it runs with 80 Plus Bronze or better. Generally if you can easily find a brand (I.E Corsair) then its a sure bet, but a company that's a bit mysterious in finding steer clear.

EarthDog · Nov 25, 2014

the efficiency rating really has nothing to do with the quality of the PSU though...

One of the better bang for the buck PSU's is the EVGA Supernova G2 750W. High quality for the price of mediocrity

. That said, the Corsair HX650 will be fine as well and is a good PSU, especially for that price. Little headroom (as in I wouldn't overclock the CPU and GPUs to the moon), but plenty for stock and a bit of a bump.

It's more of an assurance that you get the rated wattage stated on the box, and that it can hold up to that wattage better. I think 80 Plus Platinum is a waste however, it's generally a large price hike over 80 Plus Gold. Unless your electricity is really expensive then the price difference is not justified.

EarthDog · Nov 25, 2014

It doesn't mean that either. Its an efficiency rating. That's it. It has nothing to do with the quality of the unit or if it can put out its rated amperage/wattage. I can point you out plenty of Bronze/Silver/gold units that are junk in ripple, transient response, and have cheap internals.

Some companies cheat the efficiency rating or are just have no quality control by running the text in a cold room and not using ambient temps or even raising the temp to stress the unit. So a PSU is not A PSU. Its about trust. There are a long list of companies that should not be selling power supplies.

This is sig rig running Furmark. A healthy chunk of that wattage is the CPU being given hella volts. Make of this what you will. I saw closer to 600 when I backed off the CPU OC. Both GPUs are running stock speeds.

I'd subtract 200-300 watts for the CPU.

Jetster · Nov 25, 2014

Yep. Its an AMD rig

And subtract efficiency numbers from there....

True..

Call it about 89% and it's about 178 to 267 watts.

I doubt Lightbulbie will be overclocking them as much as I am. I'd say 100w on CPU is a safe guess (allows for moderate OC), plus dual 770s, plus about 50-60 for the rest of the system.. I'd say a half-decent 650 watt would do the trick rather nicely.

Specs for GTX 770

TDP (yes, I know that's heat, not power usage) for the FX 6100 is about 95w.

Bonus edit: I had a dual HD 4870 setup on a 550w PSU back in the day, but it eventually killed it. It's not completely dead now, just weak. Started getting artifacts in game. Swapped PSUs with something stronger and artifacts were gone.

Nobody does anymore, their last registration for a PSU was in 2012. They haven't certified a single PSU since.

Last I checked, Huntkey made their 550W unit. I'm unsure now however, as that was an older model.

I came here to say, for the love of god, do not buy an Aywun PSU.

Not quite how it works.

Jetster said:

Some of them don't get their PSU's officially certified by the THE 80PLUS verifier (plugloadsolutions), and run their own test. They just slap the sticker on after doing their own unregistered tests, and people just assume it's fact.

Lightbulbie said:

Don't do that. They're Andyson OEM, and not registered with anyone. They don't even advertise 80PLUS rating, and it has super wonky 12v rails. (I assume you're talking about the RX530SS?)
