I think youre buying junk again.

seasonic, pc power and cooling, corsair, antec, silverstone. thats the list. any of their 650 units will beat those junk 750 units. the junk units LIE about wattage, pure and simple. they rate at lower ambient temps, thats how they get "750" watts. real world temps, its far less. the reputable units test at real conditions.

To the OP, just in case you missed it the first time, I've requoted and added emphasis.

I mostly agree with this list. I use Corsair myself, and I figure if the power supply isn't over $100, it's crap.
Where I diverge from this list, is on Antec. I have had 5 or 6 of their powersupplies go tits up for no good reason... and RMA'ing them was too much of a hassle.

I ordered the Corsair Enthusiast because i got it for $104.99 - $10 Promo ($94.99) and then i also get a $15 MIR which brings it down to around $80. Plus it has a 5 year warranty, and more than 85% of the 102 feedback are 4 star or above. I took everyones opinion into consideration and it came down to this one. I will be coming back to this thread after a few weeks with updates. Thank you everyone, and thank you vapourminer for the list of good manufacturers to choose from, that helped ALOT.

Excellent choice.  TX-series is legit.

Solid choice.  It likely will still be powering miners 10 years from now.

That power supply doesn't have a UL (Underwriters Laboratories) sticker.  UL evaluates electrical devices for insurance companies to see if they have any potential to catch fire or an electrical shock hazard. To do that, they load them up to 100% of their rated load, put them in a chamber heated to their upper temperature limit, and run them for a day or so. They also test safety issues, like shutdown or fuse blowing in the event of a short circuit.

On each UL sticker, which must have a hologram UL mark, there is a certification number. UL has an online database where those can be looked up. Phony UL stickers are common, but they rarely have a UL hologram and a number that matches the product with that number in the database.

Power supply "reviews" that don't include a bench test under load are meaningless.  The people who do serious power supply testing report that UL-rated power supplies don't fail under load.  UL doesn't test electrical noise, voltage regulation precision, or fan noise, because those won't cause a safety hazard.

Anything that can't pass a UL test is junk.

IMHO just get the Corsair AX850.  I was running a 5970 and two 5870s on it with no problem... power at the wall was 820W or so, but that's with the stupid 100% CPU usage driver bug.  It should be a few watts less whenever AMD decides to fix that bug.  But yeah the Corsair AX "Professional Series" will handle 90%+ load 24/7.

Have a look at Antec Earthwatts. No frill PSUs, they dont look shiny or have no fancy paintjobs, but they are excellent and affordable.

strange, I have bought tons of thermaltake products and never had a problem with any of them.

I was running two 5870s and a 5850 on my Thermaltake 750W for about a couple months without a problem.  But that was with an external fan blowing into the PSU.  Within an hour of turning the external fan off the PSU just died. Sad

It's all about the game, and how you play it
Why would you recommend Rosewill when the highly rated Thermaltake unit is the same price?

http://www.newegg.com/Product/Product.aspx?Item=N82E16817153136

OP this is likely the cheapest powersupply I would feel comfortable using in 24/7 mining.  Honestly I am surprised it is this cheap.  I would consider it a solid price @ $20 higher.  I would pick the Thermltake over the Antec given they are same price.  The corsair unit is solid but also $20 more.  Either one should power a miner solidly for years (both have 5 year warranties too).

Remember mining punishes computer hardware. It puts them in loads and situations that 99.999999999999999999% of computer hardware never experiences.  While the POS powersupply you bought might work fine in a "normal" computer, mining is just brutal and you need equipment that can handle that punishment.  A powersupply that is built to be "good enough" will choke and die on the load mining put on it.  Maybe not on the first day, maybe not even in the first year but eventually it will die most likely due to blown caps.


Simple, I've lost 3 thermaltake 750w units and no rosewills.

That antec is multi rail according to their specs. get the other one or consider this one http://www.Newegg.com/Product/Product.aspx?Item=17-182-133

just get this silverstone 700w. it's $10 more than the rosewill

http://www.newegg.com/Product/Product.aspx?Item=N82E16817256072

or you cant go wrong with this one but it's $130
http://www.newegg.com/Product/Product.aspx?Item=N82E16817256059

Thats actually $95 after shipping - and its open box. And i need more than 700 watts.

I think youre buying junk again.

I went through and i picked two different PSU's - the two i picked are:
http://www.newegg.com/Product/Product.aspx?Item=N82E16817371051
http://www.newegg.com/Product/Product.aspx?Item=N82E16817139021

And im leaning more on the Antec.

roswell is crap.

You want a really good PSU without breaking the bank?

Get a Thermaltake TR2 750 watt

I have two thermaltake PSU's a 750 and a 1000 and they are both amazing.


Rosewill is fine it's neweggs house brand, the only psu's I've has fall are thermaltake 750's.
But the one you showed us is multi rail, you want a single rail power supply.

And not to mention the downtime from mining and time invested in fixing stuff.

Garbage & Garbage.

You seem unwilling to learn the lesson.  My prediction is under the kinds of loads mining creates those new powersupplies go tits up within a year.

In the long run you will end up paying $200+ in cheap powersupplies instead of just buying a quality unit first.

1) Buy a real name brand.  Companies which have to protect their brand otherwise gamers won't buy their high end units.  Neither of those Chinese POS brands has anything to lose.  Nobody with any knowledge buys them anyways.  It would be stupid for them to not sell you a POS.

2) Mining uses a lot of power.  Unless your power is free you should be looking at 80 SILVER as minimum efficiency standard.  Lower efficiency is simply more wasted heat/cost and more thermal stress on the powersupply.

+1 You are making the same mistake again. Cough up a little more dough and save yourself from further headaches.
