Question about +12V rails

[TequilaChaser]

What are good PSU brands in addition to Seasonic, and what are some brands folks don't like?

Hello Brooke,
there are several different "Brands / manufacturers" out there that have some models built by Seasonic, while their other models are built by cheaper and lesser quality companies..

I am using 2 Thermaltake PSU units that are built by Seasonic currently, on my 2 main computers

On another pc of mine, I have an older "Original" PC Power & Cooling PSU.... but all of the PC Power & Cooling PSUs for/from the last 5+ years are made by OCZ, who recently filed for bankruptcy... ( due to their poor quality in products wether it is pc ram, SSDs, PSUs, etc...

Corsair is the same way as I mentioned about Thermaltake

Antec started going downhill right after their Antec - II models came out, iirc of what Skuzzy told me.... and that was like around the years of 2003-2004???

Hope this is helpful

I had a PC Power and Cooling 750W PSU that failed after two years and it was a pre-OCZ model.  I replaced it with a Corsair TX-850 that's worked flawlessly for the past few years but, unlike a lot of the Corsair PSU's, this one's not manufactured by Seasonic.

If you buy a rated supply (bronze, silver, gold) and do the math to make sure there's nothing funny going on with the numbers and plan for a little overhead you're probably going to be OK.

And, as can be seen by my PSU choices, I always look for a single rail design so I know exactly what it can deliver.

Sorry to hear about your short life of your pc p&c PSU, BE.... They carried a 5 year warranty on them, best I recall...

I too, only look for single 12v rail PSU units , preferably with a silver or gold rating these days... almost all seem to have at least a bronze 80% rating anymore....

My Antec EA-750 PSU I currently have lists its power output on the 12V rails, with 4 +12v rails each with a max load of 25A. I'm considering a new GPU, which requires a 42amp 12v rail and would like to know if my current PSU would suffice? The card I'm looking to run is a EVGA GTX 780 3GBhttp://www.newegg.com/Product/Product.aspx?Item=N82E16814130917. Would my current PSU be up to the task?

Back to the OP.    Not too hot about Antec PSU's.     I bought this one to as the backbone of my system built just over a week ago:  http://www.newegg.com/Product/Product.aspx?Item=N82E16817139010

I believe this list with the side notes is still valid information: http://www.tomshardware.com/reviews/power-supply-oem-manufacturer,2913.html

I had the HX850 version. My first one made a bad buzzing sound at start up and the 5v rail was dead. After the RMA the second one made a rattling sound and had a terrible load dependent coil whine. (When I start up a power demanding task you hear the thing go from like a *eeeeeee* sound to a *iiiiiiiiiiiiiiiiiiiiiiiiii* sound). And just a few weeks ago it died. First one was DOA and the second was dead in under a year. I refuse to buy corsair power supplies now.

According to my previous post here the HX850 is made by ChannelWell, who is known for cheap products. Both price and quality...

It's too bad -- I otherwise would like Corsair based on its name.

We just need a company called JUGS....

You still can, just choose the model right:

so the Antec 750 i bought that claims 40A on the 12V rail is a lie?

can you test how many amps are at the plug?

No, that could be right.  It's actually conservative (50 amps total at 80% (750/12*0.8) with the other 10 to the other 12V rails) so at least they don't seem to be overstating it's capacity.

Crazy handy tool for calculating this stuff

The Interwebs can be used for something other than Aces High?
