Hello,
I have a 480 watt PSU and I want to but a GTX 650 Ti but it recomends 400 watts. I have 3 hardrives and a amd 6000+ that pulls 80 watts. Do I have enough to run a GTX 650 Ti.

with 3 hard drives nah I think your pushing the limit. You need a new Power Supply

HDDs barely pull any power... if he's got enough amps on the 12V rail, he's fine...

I have a coolergiant
Model: EG485P-VHB {24P)
480 Watts

Also I have 2 GB of DDR2 800 Ram would that be enough. Because on newegg it says 4 GB is reccomended

I wouldn't use that power supply unit for GTX 650 Ti. It's ATX V1.3, which means it won't have enough power on the 12 V rail. I'd suggest getting a Corsair CX 430/Antec VP 450 at least.

The power supply's you gave me are less in watts then I already have
Could I go 550 watts though

So how much power do you think a HDD requires?

Sorry I guess improper judgement about this one... you guys can take it over from here.. I'm..just gonna...Lie down..now.

Any other good GPU's besides 650 ti that could work on my PSU

Not really sure. Could you read the label of your power supply unit and tell us how many amperes it has on 12V rail?
December 23, 2012 7:47:10 PM

ac input :115v/230v~, 50-60 hz, 10a/5a
DC output: +3.3v/34a , +5v/40a , +12v1/16a , +12v2/15a , -12v/0.8a , +5vsb/2.5a , +3.3 v &5v/280w , total power/480w

a 7770 would be a good card for you!

500w+ will put you in the safe zone.

I like Readon but I prefer Nvidia

I wouldn't go with HD 7770. HD 7750 would be a better match for that power supply unit.
December 23, 2012 8:46:49 PM

So will my current PSU work with a 650 Ti or I have to upgarade my PSU

I gave you my chart so that is the info you needed

No. It will not. It probably doesn't even have the connectors required for the GTX 650 Ti.
December 23, 2012 9:03:01 PM

Any reccomended 500+ watt Psu that will work with it
December 23, 2012 9:16:51 PM

It needs 20a and a six pin connector
December 23, 2012 9:22:44 PM

Thanks for your help also I have 2 GB of DDR2 800 Ram. On new egg it reccomends 4 GB. What do you think

It's better to have 4GB of course. But DDR2 is replaced by DDR3 and that makes it more expensive. If you're thinking of upgrading the rest of your system soon, you might want to save up your money instead.

What's more powerful a gtx 650 or a 7770

The 650 ti is faster then the 7770, while the non ti is slower.

I did not see a combined on the 12 volt rail. If i recall right, I saved about 5-10 watts by pulling a hard drive from my system. I have a sneaking feeling because of the power supply, it pushes more 3.3 and 5 volts then 12. This is not ideal for today's systems.

Its all about power supply quality. A quality 300 watt WILL actually run a 650ti on a non power hungry system(95 watt cpu and low powered board). are 6000+ not a 125 watt rated part?
December 23, 2012 11:10:07 PM

Sorry nuke master I did not really understand the last paragraph my 6000+ is the F3 the 85 watt version

He meant that a quality PSU with low advertised wattage is better than a mediocre one with high (overreported) advertised wattage.

I did not know they had an 80 watt version of that cpu, but If you look at the power supply, it seems to only list a combined wattage for the 5/3.3 lines. This makes the design older. It also makes it hard to know just how much 12 volt power the unit actually has.

You can NOT just add the 2 rails because in most cases they come from a single rail that is not big enough to drive BOTH at full power.

Newer power supplies push most of the power into a large 12 volt rail(leaving the rest for standby and other things). That rail powers most of the system and then DC-DC conversion uses a part of it to power the 3.3 and 5 volt rails. This means higher 5 and 3.3 voltage use will take some from the 12 volt rail, but it also means that the 12 volt rail has MUCH more power then older power supplies.

For example, and older Antec TruePower(once though of as VERY good) 380 has over 100 watts less(216 watts) then the newer Earth watts 380 watt power supply(324). By the same note, I have a 300 watt power supply(22 amps @ 12 volts or 264 watts) with more power then the old 380 watt TurePower 380.

In a nutshell newer hardware uses power differently then older hardware and as such, many times and older power supply(even a higher wattage one) may not be suitable for a newer system or hardware.

This site lists your power supply as having 20amps(MAX) on its large rail that feeds the 2 small rails. This puts your just within the general requirements.

I am not 100% sure how accurate this would be, but you see it is kind of close.

Any recommended psu then that will work and be cheap also
December 24, 2012 2:38:06 AM

So basicly my power supply will not work'right

I'd say replace the PSU if you want to be on the safe side.

How much are you willing to spend. Other users have linked some good(cheap-ish) units.

Sunius recommends

Corsair CCX430
32 amps @ 12 volts or 384 watts

Antec VP 450
30 amps @ 12 volts or 360 watts

lurrps and johnsonjohnson recommend

XFX CORE 550PRO
44 amps @ 12 volts or 528 watts

All of those will run your system with power to spare.

While I personally run a GTX 650 ti on a 300 watt(22 amp) power supply. All the parts in the system had been picked with low power in mind.
December 24, 2012 3:03:44 AM

Ahh you have a 650 ti
So I was thinking about the xfx one
December 24, 2012 3:05:11 AM

Also today I found out I'm getting a sound card as a gift from a friend so that will take more power so well I guess I have to get a new one any way

Great advice for nukemaster. I want to also congratulate you on deciding to get a new power supply unit, trust me, you don't want to risk running underpowered power supply unit in your PC. One such power supply unit caught fire in front of my eyes some time ago.
