A system with on HD 7850 requires a 500W PSU with at least 28A on the 12V rails and one 75W 6-pin PCIe power connector.

The Seasonic M12II-520 is a great little PSU and sufficient for your build: http://www.newegg.com/Product/Product.aspx?Item=N82E16817151094&Tpk=s12ii%20520

is this a good PSU?

[hunter315]

No it is not. Its an old inefficient design and it is grossly overrated. You can however pick up the M12II 520 for slightly less than the S12II 520(no idea why but it is)
http://www.newegg.com/Product/Product.aspx?Item=N82E16817151093&Tpk=m12II%20520

Its the modular variant of the S12II, both are much newer, more efficient, and higher quality than that raidmax unit.

 

[demonkiller0144]

oh i see. i was trying to look for a 750w PSU or anything around it since in the future i might want to run duel video cards so i figured i would need more power. I also failed to mention since i was rushing to work this morning that i want to run blue led strips in the case so not sure how much power those take.

 

[bigcyco1]

There no need for 750Watt PSU even running two 7850 does not require a 750Watt Psu if you just want a 750Watt for whatever reason then i recommend PSU PC Power and Cooling Silencer Mk II 750W High Performance 80PLUS Silver SLI CrossFire ready Power Supply

Weird, usually the modular versions are more expensive.

@amuffin hence the do not touch status 😀

Weird, usually the modular versions are more expensive.

the seasonic m12ii series is the only odd one out i think on this rule. I wonder why they aren't reversed.

 

[hunter315]

They normally are, M12II 620 was a bit cheaper than the S12II 620 recently, the M12II sold out so now the price got adjusted but sometimes weird things happen to the prices, i think it is because newegg's pricing model is automated. One time the Hyper 212+ sold out and its price went from 30 to 45 when it came back in stock because the computer thought it was a good idea.

 

[demonkiller0144]

i thought i would have needed a bigger PSU but if not then 600w should be fine? sorry i keep jumping around with the sizes dont want to get one too small that it wont work or waste money on a big one i dont need. thanks for all the help guys

 

[dudewitbow]

the 7850 is a light card on its own, its power consumption in watts is only in the late 200's on load. that's the magic of modern gpus, lower power consumption.

 

[bigcyco1]

To set your mind at ease just get this it will run x2 crossfire 7850 you will be able to overclock them and your cpu and still leave you breathing room PSU:CORSAIR Enthusiast Series TX650 V2 650W ATX12V v2.31/ EPS12V v2.92 80 PLUS BRONZE Certified Active PFC High Performance Power Supply

o.k. let me try to briefly explain to you about how to pick PSU i apologize for being short with you but i must go to bed as i half to get up early. As much as the power (Watts) requirement matters, the current requirement, measured in Amps is as important if not even more important. This is especially true if you have a or several dedicated video card(s). As a general rule of thumb, you’re aiming for the highest number on the 12V line.

Power Supplies that are certified 80 PLUS have been independently tested for their efficiency. Now, there are 4 different 80 PLUS certifications, depending on how efficient the power supply is:

80 PLUS: The power supply is at least 80% efficient at 20%,50% and 100% load
80 PLUS Bronze: The power is at least 82% efficient at 20% and 100% and 85% efficient at 50% load.
80 PLUS Silver: The power is at least 85% efficient at 20% and 100% and 88% efficient at 50% load.
80 PLUS Gold: The power is at least 87% efficient at 20% and 100% and 90% efficient at 50% load.

The 80 PLUS and higher certifications are the way to go when you are looking for an efficient power supply.

Do not trust specifications such as “Efficiency: 80% to 85% Efficiency Typical” that are not 80PLUS certified. 80 PLUS is an independent standard test. No 80 PLUS and “Efficiency: 80% to 85% Efficiency Typical” means that it is 80% to 85% efficient, according to the manufacturer that is, using their own in-house test, which may or may not so much represent real efficiency.

Your right thanks for correcting me i am tired :lol:

 

[Rugger]

There's actually a Titanium rating, too.

 

[Rugger]

Not that you find a lot of titanium rated PSUs actually in the market...The only one that I know is a Dell: http://www.plugloadsolutions.com/psu_reports/DELL_D750E-S2_750W_SO-386_Report.pdf

 

[bigcyco1]

I did not know that.Nods Thanks for the info !

i was told by a friend that this is a good PSU, is he right?

 

[dudewitbow]

http://bigbruin.com/2007/heczephyr_1

from info on other sites, its the only HEC line psu that's actually usable. but at this price range, there are tons of good psus.(especially since this line dates back to 2007, which is like 5 years ago)

For that price you are way better off getting the M12II-520 and you'd be getting a much better psu.

id def go with a plus or higher, not only are they efficient they prob will pay for themselves on your power bill, it adds up depending on how much the pc is gonna be used non certified ones usually use more on your electricity bill and end up costin more in the long run
