Corsair TX650/HX650/TX750 vs Antec Truepower 750w

[bunit]

Hey all

Looking for a suggestion for my PSU for my future build.

i7 860
ASUS 5850 (might be replaced by ATI 6xxx SI series due in Q3/Q4 right away)
4gb DDR3
Intel G2 SSD

I don't think much else is important? Anyways

I know that all 3 of these units are considered pretty decent.
Having 750w is always nice, would I possibly need it in the future? I will be upgrading GPU for sure, possibly CPU/MOBO.
The last thing I want to buy in the future, like 2-3 years from now, is a power supply? Why? Well the old one basically goes to waste, and its a complete waste of money.

I'd like my PSU to be a one and done deal for the next 3 years at least.

Anyways.
Price comes into consideration as well:

TX650: $89.99 - $10 MIR
TX750: $109.99 - $20 MIR
HX650: $119.99 - $20 MIR
Antec Truepower 750: $119.99 - $20 MIR


I'd like this to be a sustainable PSU that could conceivably drive a single GPU + CPU + whatever else combo 3 years from now. I'd much rather spend $20 extra bucks now for some extra wattage than have to buy a whole new PSU down the road. I'm leaning towards Corsair because everybody seems to use it, but at the same time I"m not sure about their lower end TX units as opposed to their better, more pricey HX units. People seem to really like the Antec Truepower and 750w is always nice for futureproofing.

Which would you get, and why?

Thanks in advance.

Personally, I'd take the Antec TP-750 over the Corsair TX's.

Better voltage regulation, better ripple/noise control, more efficient, and is Seasonic built, based on their S12D platform.


The downside is the ridiculous 4-pin ATX and 8-pin EPS connectors being two entirely separate cables. Most power supplies have a split 4+4-pin ATX/EPS connector, but the TP-750 uses two dedicated and separate fixed cables for those.

That's the worst of the TP-750.

As for the HX650, it's basically a rehashed HX620 with its higher ripple/noise generation than the TP-750.


Would I own an Antec TP-750? Yes, as I've had one for about 8 months now, along with an older Corsair HX620 that's still percolating after almost 2 years and a newish HX850 that I got on a nice sale price (wouldn't have purchased it otherwise....)

TPN-750. Places in between TX750 and HX750 in performance, while being mostly modular (except for the extra cpu connectoe meghan mentioned, everything that's hardwired would be used anyway) and at the same price as TX750

I have a TPN-750 coming this way, which i was planning on hooking up to this computer here:

Then on another rig, I have a TX850 feeding the following:
i7 860
TP55
HD5850
1 gentletyphoon
2 tricools
1 twinturbopro
2 7200RPM HDDs
1 BDROM drive
2x2gb DDR3

Both systems will have overclocked CPU / GPU.

While I have no doubt either PSU will be more than plenty for respective systems, what do you think would be a better match for the absolute best result (if there is such thing, in terms of efficiency? noise?)?

If I were to put the TX850 on the AMD rig in the link, I would have to remove it from the i7 machine which doesn't bug me much. The only thing that sways me either way is the antec's half modular nature, that might come in handy for the more cramped 300 case the AMD rig is housed in.

Your thoughts?

No, actually it's an S12 with the VRMs of the 12D.

From the technical aspect, the Antec is the best of those, having VRM for the minor rails and being more efficient than the rather old Corsairs.
