The corsair vx450 outputs in excess of 500w at > 80 % efficiency. Yet, it has only one 6-pin PCIE connector. The high-end graphics cards today require two 6-pin connectors or one 6-pin and one 8- pin connector. Many graphics cards come with convertor cales . Is it advisable to use these? And, if it is not bundled with card, does anyone know where to get these? Can anyone who uses this powersupply with graphics cards which require 2 power connectors give their feedback?

Yes, get a higher rated PSU like the 550W or Corsair 600W.
I have the 450W and I use a 4850 GDDR5 version which uses 2 PCI-E power slots. Its running without any issues whatsoever on my PC.
However a higher GPU like the HD4890 or GTX 280 etc may cause instability and crashes with the 450W Corsair.

There were some guys claiming that the VX450 can provide 571W and so it's safe for so much more than 450W or something like that.
Please read this thread and i hope it helps you.

Please check this reply to a similar query some days back.
It should hopefully answer your doubts.
User was facing issues as he had imho, a grossly inadequate PSU.

As some one who used the vx 450 with a HD 5850 i can say that it does work without a problem with the converter, the hd 5850 along with full system load hardly goes over 350 watts for normal gaming .... but if you are buying a new psu and you are getting a decent card then i will certainly get a a vx 550 as minimum.
Considering the warranty time frame on the corsair i would buy any of the HX series as it might easily last you 5+ years and even if not you still get 7 years warranty with the HX series.

I don't think we should suggest the HX620 anymore.
HX620 is outdated now and may be EOL.
The HX650 costs the same maybe and the new HX series with the blue-coloured labels have 7 years warranty as against the original 5 years on the red-colour labelled HX620.
In fact the HX650 also seems like a rebadged HX620 from a quick comparo of the specs/graphs.
The HX750 looks like a very strong and nice PSU for the discerning users just as the HX620 used to be at one point of time.
Looking at the new systems we buy now, the CX400 and VX450 are for the entry level gaming rigs from an enthusiast's POV.
VX550 and higher recommended for anyone buying a HD5770 or higher with a new, esp quad-core processor rig.
I already have a system with corsair vx450 purchased 3 weeks ago. I am currently using the integrated one and waiting for the Northern/Southern(?) islands, particularly the mid-range 6700 series, to come out. There are rumors that these use 256-bit memory bus and hence the power consumption might go up and hence require two pcie connectors.
VX450 can handle even HD5870 so don't worry about using a converter cable (it can supply 570W at peak)
It all depends on the budget, if you are economically well off then VX550 all the way, there is no single GPU it cant handle and wont be able to handle even in the future.

It can, but I wouldnt take a risk at sustained loads. There is a reason Corsair isn't badging it as a 550 watts. Your reply is rather short-sighted. If a person can afford a 20+ k card, it would be foolish to buy anything under a HX650. You are completely forgetting the fact that most of the people who buy high end hardware, are enthusiasts. Any sort of overclocking will require a stable power at high load levels.
Pegasus posts, makes complete sense in buying a VX550. It's good to see a new member posting logical posts, rather then the rubbish which is filling up TE's tech sub-forum.
Ok, so now I buy a VX550 for a 5770..:rofl:Aces170 said:
I was merely trying to tell the extent to which VX450 can handle things, and I did not intend to in any way whatsoever suggest anyone to run a 5870 on a VX450
If you will deliberately try to find errors in the post I made, there is nothing I can do about that. As I said it all depends on the budget, an enthusiast who will be getting himself a 5870 will probably know what PSU he will require and will have a budget for a higher end PSU
It is not very good to see Global mods like yourself support such vague views.

Please read it and please just don't read it, please try to undertstand too.
It's a sincere and humble request to all who suggest a VX450 when it's safer/smarter for the buyer to buy a VX550 instead (or something more as per budget) -
"Rest assured with VX450- it can provide 570W".
You may be rolling on the floor with laughter over what i say.
But some day you might realise the joke was always on you.
The worst part, it maybe too late as you may have suffered some loss/damage already and that too because it was no one else but you who folled you.

I, as I wrote earlier, said that the 570W is the peak value so can you please explain as to how you perceived it as me saying it can provide that power 24/7?

So how did you plan to run that 5870 on a VX450?
Just turn it on, hear the PC beep and turn it off?
How can we make general statements- what if user has OCed i7 rig?
Others will only perceive what the poster potrays.
You don't get it, do you?pegasus said:
I said it can handle, I do not recommend it. Ever heard of "Minimum requirements" and "Recommended requirements"? And anyways as Aces said that a person who will buy a 20k+ GPU will have a budget higher than 4k for the PSU.
pegasus said:As per this statement (underlined), there was no need for you to say what you said in your first post here?
Did the OP ever say that he had a 5870 and needed suggestions regarding what PSU he should buy?
His question was whether or not VX450 had enough in it to power a GPU which required two 6-pin PCI-E connector and as I myself have experience of running a 5850 on it (which required two of these) I wrote he shouldn't have any problem.

OMG!pegasus said:
My apologies sir, sorry for having argued with you. It was my arrogance that I was not able to acknowledge my very apparent mistake
Anything below a VX550 for HD5770 is serious stupidity and the one who doesn't understand this will repent later when his GPU or motherboard gets fried
At the OP
As you have already bought the VX450 just use the molex to PCI-E connector for now and if you feel the card power requirements exceeds what the VX450 can provide just sell the VX450 as it doesn't depreciate much in value and get a higher rated power supply....

All that had to be said has been said in the earlier posts, whether it was from me or you.
Read the entire thread and any links when you are calmer and thinking a bit more clearly.
You started off with confident statements and later seem to be beating a hasty retreat.
To state why one may find your defence weak, esp the 5870 part, "OP asked xyz, so i said ABC", etc- i can give a few examples.
eg. 1>
One guy asks on forums if consuming poison will kill them.
One smart guy says- NO, it won't. I know someone who tried committing suicide once and consumed poison but didn't die.
OP has poison and dies.
People accuse the smartie.
Smartie says- i said he/i consumed and didn't die. I never said OP should consume poison.
eg.2> Someone may stand in the middle of a busy street every day of their life, despite seeing the warning signs and never get run over by any vehicle.
That doesn't mean someone else will be as lucky or the knowledgeable/smart/sensible person will suggest others ignore the warning signs and do the same.
The only thing i would add here and might not have mentioned previously is-
Say one is running an E8400 rig and is buying 5770 and asks for psu.
Everyone says buy VX450 and they are not wrong (just about adequate for now imho).
But do we buy good quality PSU with "5" years warranty to have to upgrade it year or 2 down the line"
Year or 2 down the line, we mostly have some quad or X6 or x58 setup.
By that time, anyone who affords a good card now will upgrade to a good card of that time.
And then the VX450 might not enough even though there's quite some warranty left.
Would it seem feasible to sell the psu and buy something new then.
Or rather spend a bit more now and make it last longer?
These are just some thoughts i present and it's for the reader to decide.
I am not shoving them down someone's throat.
Keeping a slight headroom or thinking slightly into the future is not an unwise thing imho.
All-in-all, i had great fun in participating in this discussion.
I guess the apparently wrong or absolutely wrong claims, doubts and mostly both sides have clarified their stand.
Everyone is entitled to their opinion and the right to make a decision.
I simply prefer being safe than sorry.
We gain or lose, as per our own intellect/understanding and can't blame anyone else for our wrong decisions.
All the best to everyone.

To be honest, spend little extra and get a beefy Power supply.
This is one part of the system that does not need constant upgrade if you buy a good one to begin with. And its not like it will go to waste. The good PSU will run with better efficiency even if its nowhere near its peak local bearing capacity. I know people who are running HX620 for more than 4 years since the days of E6600.
Hell I sold my HX620 to a person who now uses it on his i7 rig. That is what you can do with good power supply. Its not a waste of money. You get peace of mind. It would have been waste of money in 2005 when all we got was VIP and uber expensive Antec PSUs. Not anymore.
SMPS is the only hardware that has not changed in 2 years in my system (other than my mx518
)
@OP
If you already have VX450, then you can try running your system on it for now and even with future cards like 6700 series as long as you are not running meaty oced i7 or Phenom II X4 setups. But dont count on anything more. It will still make sense to sell the vx450 and upgrade. You will not loose too much money on VX450. It will fetch decent money even in second hand market and you can opt for HX650.
You are putting fate of your entire system in hands of PSU, get it right from the beginning. This is one of the few items where overkill is actually better.
