560 ti with an Antec VP 450 Power Supply?

Right now I just have a barebones system with a mini-atx motherboard and Pentium g850 cpu. I have 2 Sata hard drives connected and one sata dvd burner. I could probably disconnect 1 hard drive and the burner because I don't use them. I've been reading that the 560ti apparently requires a 500-550 watt power supply, but I've also read of people using the card with lower rated supplies.

The main problem I'm seeing is that I will have to use a molex (or sata) adapter to get another 6 pin PCIe cable for the card. I read that there can be problems with split 12 volt rails and using such adapters. What do I need to look for when connecting the card, if it is possible?

I guess if this is not possible then my next best option is a GTX 460? Thanks.

No Problemo😀
 
that psu is not all that great but should have no problems powering a gtx560 ti G850 setup.

EDIT: I hope that is not the 448 model gtx560 ti though as that uses quite a bit more power than the 384 models.

it appears you have not bought the card yet since you mention maybe getting the gtx460 so why not get something alike a 7770? plus the gtx460 needs two 6 pins just like the gtx560ti.

EDIT: and running the 448 model would be too sketchy IMO. your psu is their value line made with cheaper components plus it only makes 360 watts max on the 12v line. and thats probably at an unrealistic 30 C to which means real world available power would be lower even when brand new.

Well I really don't want to get an ATI/AMD card because of poor drivers. Not only in Windows but in Linux as well.

That's fine about the 448 because I didn't really need it. I was just wanting to get a 560ti because the gtx 460 already seems to be outdated.

I have no idea about Linux but as for as Windows goes, Nvidia has been having some really crap drivers of late too.

and we could probably come up with a list of Nvidia issues too though. I normally prefer Nvidia but in your case, AMD has the better option.
 
Well just looking at some benchmarks it seems even the gtx 460 is better than the 7770 and that only requires a 450 Watt PSU.

Is using an adapter that much of a problem? I don't have any problems using one of my SATA connectors as a PCIe power cable. I just don't want to mess up the 12v rails.

Well op it seems that ur psu has dual 12v*18A rails.I wouldn't recommend running a 560ti on a 18A rated rail.
 
The 460 uses more power which is why the 7770 was recommended. I wouldn't use a 560ti with that PSU. I'm pretty conservative minded though with PSU's. The fact that the PSU doesn't have the needed connectors would be a red light for me.
 
But don't the videocards even come with the adapters themselves? I didn't realize it was a problem.

edit: It's fine I guess if the 560ti is out of the question, but if the 460 performs better, has better drivers, and only requires a 450 Watt PSU then I would prefer that.
 
Don't go for wattage,check the 12V amperage requirement for 460.And yes the videocards do come with molex connectors.
 
Well I was looking at the 7770 but it's not much better than the 550ti and has worse drivers. So I was thinking of getting the 550ti considering it only needs one PCIe connector, but then I saw the Amp requirements which were very high. Can my computer seriously not use a 120 dollar video card?
 
Wait for GTX 660, it should run off of one 6-pin like the HD7850. If not, it'll consume much less power than 560 Ti anyway
 
But what about the GTX 460 or 550 ti? The GTX 460 requires two pcie but needs 24 amps. The 550 ti only needs one pcie but also requires 24 amps. Both cards are stated to run with 450 and 400 watt PSUs respectively.

I'm assuming that the up comming 660 will also require at least 24 amps or thereabouts even though it only needs one pcie. So, according to this thread, I am not able to use any of these cards?
 
No, you should be able to run any of those cards (550 Ti sucks balls though, don't buy it). You shoud be able to run a stock GTX 560 Ti just fine as well, VP450 while a budget unit is pretty capable and your CPU is low power. But if you want the most performance per watt in your approximate price range, the GTX 660 is that.

No it doesn't.

No it doesn't.

You seem to be confusing what the cards draw, which is not listed in the specs you've looked at, with what the card makers/sellers recommend for a SYSTEM WIDE power requirement, which what those 24A requirements you list are for.

And the card manufacturers way overestimate the amperage required for the ENTIRE SYSTEM because of people trying to use Diablotek, Raidmax, Senty, et al, power supplies to power their computers....power supplies woefully inadequate and unrealistically rated (meaning, the junk power supplies claim higher output than they can deliver.)

Personally, I'd throw in a 7770 and be happy....and I still don't understand about the "bad driver" comment. Do you have specific information or are you just parroting what you've heard from Nvidia fanbois?
 
But the vp450 only deilvers 18 amps per 12 v rail which is split. 560 ti requires 30 and the other cards require 24 amps on 12volt rail.

Well the AMD proprietary driver in Linux is considered almost universally terrible compared to the Nvidia. As for Windows, not being able to run a game like RAGE puts up some red flags for me.

I also am interested in Nvidias frame limiting features they were going to implement in drivers as well as better support for legacy standards like older OpenGL stuff.

I'm surprised you (and others) recommend a 7770 though because it's not any better than a 550 ti or GTX 460 according to anandtech's benchmarks -- especially if power is not an issue.
