I'm building myself a new pc and I'm wondering if the PSU I'd be getting would be the right choice.

PC Specs:

CPU: i5 2500k
Motherboard: MSI Z68MA-G45
Memory: 2x4gb 1600mhz
GPU: HD6950 (probably)
PSU: antec TruePower 650

I have been advised that the Antec TP-650 might not be the best for higher end graphix cards and that a Corsair GS600 might be better.

Any suggestions or recommendations?
 
Seems decent, depending on how much you can afford I would get a better psu

And off topic how the hell would you login with that username :O
 
That should be fine. But I would rather go for Corsair AX750 tbh. Those are some nice stuff u got there. Wouldn't wanna damage any of it by skimping on the PSU..
 
Welcome to the forum (-(-_(-_-)_-)-)... Lol

okay seriously what should we call you?

It might seem like I'm dissing that username but in actual fact I'm jealous of its awesomeness;)
 
But would you rather go for the Antec TP-650 or the Corsair GS600? :P

The corsair... (without even looking at its technical specs) because it has better resale value

Obviously you want to keep your psu for a very long time since you're getting a quality one... then I'd suggest a modular psu!

After a bit of browsing the TP-650 seems pretty good so of those two... I'd take the Antec
 
Dude that true power is amazing, i ran a 9800gx2 with a quadcore on an antec tp 500w, so that PSU will easily run your components.
 
Scrap that PSU. Uses outdated and unnecessary quad rail design.

Quality, single rail PSUs can actually be cheaper, and would be a better option for you.

Look at the Antec High Current Gamer 520w, more than enough for your rig. Next up is the HCG 620w, but you wouldn't need that.

Both are Seasonic OEMs.
 
TP-650 is fine. There is nothing wrong with current multi-rail designs, which have good cable setups. It was the old ones with poor cable setups that led to issues, and the even older ones with independent rails. Current setups just are single rail systems split into different outputs with individual current limits (following ATX safety recommendations).

For around the same price (little over a grand iirc), though, you can also look at:

Corsair TX650(V2)
Corsair TX550M (VX550 reborn, imo)
Coolermaster Silent Power Pro 500W

Truepower is the best as far as peripherals go, being both semi-modular and having 4 x PCIE connections for CF/SLI setups.

TX650V2 is always a good choice, though is the only completely non-modular PSU here, meaning more cable management, but not by all that much.

TX550M is new, but looks great, semi-modular and looks to be the replacement for the eol but very good VX550.

Silent Power Pro 500 is just a decent all-round PSU, but definitely the weakest in terms of power output, with only just over 400W on the 12v rail. With a 6950, I doubt the reduced noise is going to be a bonus at all, even if it is quieter than the other PSU's.

If you're never going to SLI, then of these I'd pick the TX550M. It's semi-modular, has more than enough power and extremely good efficiency. You are definitely paying for premium quality and modularity, though.

For less, you can pick up the Antec HCG PP suggested, losing modularity and 2 years on the warrantly (3 vs 5 for the Corsair), but keeping the same good efficiency.

Do you have a document/web page where it shows that the Antec Truepower has 4x PCI-E connectors?
From what I saw it had only 2x 6+2-pin ones.

I'm with PostmanPot on this one, that you should rather avoid quad/dual rail PSU designs, because you simply don't know how it would distribute the load of the graphics card(s).

The Antec TP-650's manual shows that the 3rd and 4th rail is used for the PCI-E cables, but you should take note that the graphics cards also get like 75/150W from the motherboard, depending on whether it is PCI-Express 1.0 or 2.0 slots.

I was the one who suggested the Corsair GS600 PSU to (-(-_(-_-)_-)-) in the first place. The Antec HCG520/620 PSU's would also be very good options if you're on a tight budget.

Lastly, the Antec TP-650 might do the job, but I really can't say if it will due to power distribution across the rails being unknown to some extent.
If you really want to go for this PSU, then I would suggest that you look for people running similar systems from the same PSU.

You can go back and forth on rails and so forth. All you want is a reliable solid unit by a trusted manufacturer. There are other PSU brands than Corsair. The Antec units I've had have all been rock solid. You aren't going to come up against major limitations of your PSU with that setup anyway.

2 x 6 pin and 2 x 8 (6+2) pin PCI-E graphics card connectors for TP-650, TP-750 and TP-750 Blue

PCIE slots only ever supply 75W max. There is more than enough current on every rail to supply the components as indicated the the cable setup. You're asking for a situation in which the motherboard and peripherals (Molex/SATA power connections) are drawing more than 260W. Sure, it is possible, but so extremely rare as to be irrelevant for the average person.

All you are really doing is spreading FUD about multi-rail systems, imo.

PCI-E 1.0 is limited to 75W, where as PCI-E 2.0 is limited to 150W.

Quite recently someone had issues with a similar setup, but with a Thermaltake LitePower 700W PSU, which had 2x +12V rails: 30A + 22A.
In his case, it was impossible to tell how the load would be distributed, since Thermaltake did not disclose that information like Antec did for the TP-650.

I think you have convinced me that the TP-650 is fine, especially since they provide you with how the rails are spread:
Rail 1 (22A): motherboard & graphics cards via motherboard slots [(20+4) main connector] + molex + SATA
Rail 2 (22A): CPU [4-pin ATX12V + 8-pin EPS12V]
Rail 3 (25A): graphics card [PCI-E w/ blue stripe]
Rail 4 (25A): graphics card [PCI-E w/ green stripe (modular)]

If you estimate that the 200-250W (HD6950 / unlocked HD6950) would split its power equally amongst the motherboard and 2x PCI-E connectors, the load might look something like the following:
Rail 1 (22A): 250/3 for GPU + 50W for motherboard + 30W for HDD = 83.3W + 50W + 30W = 160W aka 13.3A
Rail 2 (22A): 95W - 200W (when overclocked to 4.9GHz) aka 8A - 16.7A
Rail 3 (25A): 2x 250/3 for 2 GPU connectors = 166.7A aka 13.9A
 
Prophet:
Single rail PSU's just makes the estimation of whether it will be able to handle the load MUCH MUCH easier!
 
PCI-E 1.0 is limited to 75W, where as PCI-E 2.0 is limited to 150W.

Nowhere have I ever seen 150W listed for PCIE 2.0 slot power. Are you sure you are not confusing the slot with the power connectors? 6-pin (75W) is often called a PCIE 1 power connector and 8 pin (150W) is often called a PCIE 2 power connector. Afaik, what changed in PCIE 2.0 was the new 8-pin power connector and an increase in total power draw specs to 300W - 75W from slot, 150W from 1 x 8-pin, 75W from 1 x 6-pin.

Quite recently someone had issues with a similar setup, but with a Thermaltake LitePower 700W PSU, which had 2x +12V rails: 30A + 22A.

This is mostly because it is a crap PSU, made by HEC. Yes, bad multi-rail systems are going to give you issues. I only took issue with what you said because you said, rather not buy a multi-rail system at all. If you are buying on the very cheap or looking to run certain setups on certain wattage PSU's, then you don't want a multi-rail system, but a decent multi-rail system is fine for most, and this specific PSU should be fine for the op's setup.
