Hi all,

Ok so iv finalised my build except for the psu. Need help on which one to choose.
The build:

CPU: Intel Core i7-950 - $359
HardDrive: WD SATA 1TB - $72
DVD Drive: SATA Sony - $27
Motherboard: ASUS P6X58D-E - $265
Graphics Card: 2x GTX 470 ASUS (Setup in SLI) - $399x2 = $798
RAM: 6G Kit ddr3 1600 Patriot-Signature - $169
Monitor: 23” 5ms DVI Acer G235HBMD - $185
PSU: ---------------------
Case: Thermaltake Armor A90 - $109
CPU Cooler: Thermaltake SpinQ-VT - $62
OS: Windows 7 Professional 64-bit - Already have
Wireless: PCI-E TP-Link WN781ND - $25
Headset: Plantronics 377 - $53
Build Fee: $70

TOTAL: $2194

I don't really want to overclock now. But I think in the future I will end up doing it. I will put my foot down at 3.6ghz.

So heres what I had in mind:
Thermaltake EVO Blue Gaming 750W - $165
Corshair TX 750W - $148
Corshair TX 850W - $178
Antec TruePower TP-750 - $148

Keep in mind that this is all Australian currency as I live there.

Thats the website if any of you can understand it. I don't plan on buying anywhere else so please dont suggest anywhere. The PSU's are on the 2nd page, on the right hand side.

Thanks

I would go for the TX850W =. Although the TX750W should be good enough. Just advise on the 850W for some room for OC'ing and adding other peripherals later.

"However, don't touch the TX series, they aren't modular, therefore they suck."

Quote I just found somewhere else. Do you agree with that orrr?

Whoever said that is an idiot. The tx series a great series of PSU's. I don't know if you'll need 850w though, but it can't hurt.

Who said modular is better? Costs a lot more and don't offer any other benefits other than good cable management.

Oh well... Maybe he is a neat freak. Modular PSU's are better, they are equal to non modular PSU's if you look at performance. That statement is bullshit!

_PANIC, if you are going to SLI two upper end video card with a 750TX or 850TX, you are not going to have many cables left over. And any of the current "gaming" cases have plenty of space to tie and hide unused cables.

I agree with hell_storm. His statement is bullshit.

Ok,

So the 'Corshair TX 750w' and the 'Antec TruePower TP-750w' are the same price. Which do you think?

Corsair is my personal favorite. But on this one, I would recommed the Antec one.
Antec TruePower TP-750 Blue 750W.
More Amps and 80+ Bronze Certified.

I'd say it's a tossup. The Corsair will stay within specs at 900 watts:

The Antec is a more modern design that has also done well in tests.

My opinion: The difference between 60 and 62 amps is insignificant. If you are running that close to where those 2 amps make a difference, you need a more powerful PSU.

^^Isn't the TP 750W 4 rails of 25A each? So doesn't it make it a total of 100A?

Not if the single source feeding those 4 rails can only output 62A. Wiki OCP to see how "mulit rail" PSUs really work.

The Corsair TX750 is a quality unit, but the model from Antec has better efficiency, is semi-modular, has better internal componentes, lower ripple/noise on the +12V output,...
On the other hand, the cables of the TX750 are huge.
5 years warranty both.
