Hello there fellas

You should know the shpiel by now :kaola:  limited options for me as I live outside the great US of A. Which of these power supplies do you recommend? I need 750W

- Antec High Current Gamer HCG-750 (link)
- Antec TruePower New TP-750 (link)
- Cooler Master GX Series RS750 (link)

johnnyguru wrote some pretty nasty *** on the GX but I have seen good reviews on the net all around. I am tempted to go with the TP-750

Have your say :)

Motherboard: Asus P8Z68-V PRO/GEN3 ATX LGA1155 Motherboard

Power Supply: Cooler Master 750W ATX12V Power Supply

So over at AnandTech and HardForums people have mentioned that 750W is way too much for my machine and I should look for 500W PSUs!

I have the following options:

The only 500W unit that he carries and has decent reviews is the SilverStone ST50EF-PLUS
Any thoughts?

HardwareSecrets
Newegg

He also has a cooler master eXtreme power plus 550, but I am gonna stay away from cooler masters after what I heard/read about the GX

A quality 500W PSU will be sufficient for the build you listed. There is however, a benefit to using a PSU with 2 times or more power than what the system pulls, which is that the PSU fan will not ramp up until it reaches 50-60% load.

I myself have a TP-750(Blue version). This is my configuration:

-Raidmax Smilodon case
-Antec TruePower New TP-750 Blue 750W PSU
-MSI 790FX-GD70 MB
-AMD Phenom II X4 955 BE
-4GB Mushkin DDR3 1600 RAM @ 7-7-6-18 1T
-HIS Radeon HD 4890 1GB
-Seagate Barracuda 1TB
-Creative SB X-Fi XtremeGamer
-Windows Vista Ultimate 64 bit

It's going on 3 years strong. Nothing wrong with going with the HCG-750 or TP-750. They're great PSU's. The TP-750 is semi-modular so it would be less cluttered for a mid tower case. If you don't mind the extra cables, the HCG-750 would be okay too.

Overclocked, water cooled, extra bling system
http://www.guru3d.com/article/msi-geforce-gtx-560-twin-...
289 watts AC under a game type load
~90% efficient psu
~260 watts DC
Without overclocking and/or running power viruses the OP's system will never put a 50% load on a 500 watt psu.
And if he does, stressing the psu to 60-70 even 80% load while gaming or benchmarking for a few hours won't hurt it.

Thanks for the insight guys :) 

another poster on another forum has said that i should only consider buying the TP if the price difference between it and the silverstone is less than 30-40 bucks (its a $100 diff for me!) to future proof my system

I am secretly hoping they run out of silverstone so I am 'forced' to pick up the TP :p 

But it really seems that the TP would be a complete overkill on how i would use the system (does it matter that i live in the middle east with high temperatures impacting efficiency?)

Ditch the V-Pro for the V or an asrock board, and grab yourself a gtx 560TI. As for your powersupply, the TP and HCG R@P3 the GX...

That buying guide isn't speccing a PSU for your rig and their PSU numbers are inflated. The ST-50F is sufficient for your build.

The logical pc buying guide says that for a build similar to mine, I should go for an 80+ 600W+ PSU

Getting nervous now with all my other components at stake!! I might get the TP750 just and shell out an extra $100 just to be safe :sweat: 

That's a list of builds reccomended by the author, not much logic to it
In one instance he reccomens both a 520w and a 650w for a system ( the one he calls Very Good ) similar to one of Tom's budget builds that used a 430w

There's nothing wrong with having more power than you need, other than the added expense
