Do I Need a New PSU?

post #1 of 30
Thread Starter 
Hey,

I'm new to these forums, posting because I want to upgrade my 9800gt. The graphics card I'm looking at is a GTX 560 ti. This is my current rig:

CPU - Intel Core 2 Duo E6850 @ 3.0ghz
Motherboard - Intel EP41T-UD3L
Graphics Card - 1GB 9800gt
RAM - 4GB DDR3
DVD Drive - HP DVD Writer 300n ATA
HD - Seagate 750GB Desktop SATA HD ST3750630AS
PSU - Besta PT-500

The only other thing I have plugged into my PSU is some 4 pin USB adapter, if that makes sense.

Here is an image of the PSU's specs:

Is my current PSU good enough for what I want? It also seems that I don't have a spare 6 pin connector (Do I need one when it says the GTX 560 ti requires 6 pin x 2?). One final question, my 9800gt is 9inches and a GTX 560 ti is 9inches, does that mean it'll fit into my rig perfectly?

Could you please recommend some good PSU's for my rig if I do in fact require an upgrade. Thank you.

That's a no go for sure. In fact, I'd stop using it with your current setup if possible.

It's an old design with most of the capacity on 5V/3.3V rather than 12V. Most power draw in modern systems (like around 90% but it depends) is from 12V. That power supply only claims to be able to output 17A on 12V, which is 204W. Also, the output power could be of low quality because (1) the unit is probably not that good to begin with and (2) it was not designed for 12V-heavy loads, so it's probably being crossloaded out of its comfort zone.

If you want to upgrade to a (single) GTX 560 Ti and have some room for maybe a better CPU down the line, a decent option would be the XFX Core 450W for $55 ($45 AR)

You only really need more if you're looking into multi-GPU setups later. If you are fine using a molex -> PCIe power adapter, a cheaper option would be the Corsair CX430 V2 for $45 ($35 AR):

Thanks for your reply!
In regards to the XFX Core 450W, nvidia recommends a minimum of 500w for the GTX 560 ti, but is that only as a precaution for people who have cheap, poor quality 500w PSU's?

450 might be cutting it real close. This is from-560ti review (3d guru).

http://www.guru3d.com/article/geforce-gtx-560-sli-review/

Measured power consumption

1.System in IDLE = 201W
2.System Wattage with GPU in FULL Stress = 449W
3.Difference (GPU load) = 248W
4.Add average IDLE wattage ~ 50W
5.Subjective obtained GPU power consumption = ~ 298 Watts

GeForce GTX 560:
On your average system the card requires you to have a 500 Watt power supply unit.

GeForce GTX 560 in 2-way SLI:
A second card requires you to add another ~175 Watts. You need a 700+ Watt power supply unit if you use it in a high-end system (800+ to a KiloWatt is recommended if you plan on any overclocking

This is correct. Also, there are many out there with CPUs that take a lot more power than yours.

Regarding actual power consumption of the GTX 560 Ti itself, it's rated for 170W TDP but actual power draw may be a little different. xbitlabs measures about 160W from the card itself, and unlike most review sites they actually are measuring 3.3V/5V/12V draw directly instead of estimating from AC wattages. You can see the card throttling itself in OCCT:
http://www.xbitlabs.com/articles/graphics/display/geforce-gtx-560-ti_4.html#sect0

A factory overclocked card or a card you overclock yourself will take a little more than that. With slightly higher stock voltage you'll get a bit higher as well.

That guru3d review is of GTX 560 (not Ti) and they're looking at SLI power consumption. They estimated about 150W per card. And somehow they get SLI GTX 560 to use more power than SLI GTX 560 Ti, when the Ti ones have more shader processors/CUDA cores/whatever you want to call them operating and are clocked higher?

The entire rest of the OP's system is probably not using much over 100W full load, so I wouldn't call 450W low.

NVIDIA's power supply recommendations (and AMD's) are concerning peak-rated units. Quality power supplies like the 450W XFX Core Edition are continuous rated units which means they have a greater capacity than many 500W peak-rated power supplies.

The 449W was pulled from the wall outlet. If I assume 85% power supply efficiency during the power draw, then that means the system pulled about 382W from the power supply.

So that's why a 450W continuous-rated power supply would be enough.

Thanks for the reply's. What about something along the lines of this: http://www.newegg.com/Product/Product.aspx?Item=N82E16817152040. It's cheaper than the 450w, is it better as well?

Thanks again.

Unfortunately, no. That unit is almost a death wish. redface.gif

Can you afford $49.99 shipped? If so, then I recommend the 530W Rosewill Green Series (it's actually a good unit):
