A reference clocked GeForce GTX 280 will draw a maximum of 19.7Amps from the +12V rail(s) under full GPU load. It also requires a6-pin & an 8-pin PCI-E Supplementary Power Connectors.

There are at least three different model numbers for the Thermaltake TR2 500W power supply unit:

Model: W0379RU
Max. Power (W): 500
OEM: HEC
+12V1: 25A
+12V2: 18A
Max. Load +12V: 420W (35A)
Warranty (years): 5
1 x 6+2pin & 1 x 6pin PCI-E connector

Model: W0093
Max. Power (W): 500
OEM: CWT
+12V1: 14A
+12V2: 15A
Max. Load +12V: ?
Warranty (years): 3
1 x 6-pin PCI-Express

Model: TP-500P
Max. Power (W): 500
OEM: FSP
+12V1: 36A
Max. Load +12V: 432W
Warranty (years): 3
1 x 6+2pin & 1 x 6pin PCI-E connector

The only two models that may be capable of running the GeForce GTX 280 are the W0379RU and TP-500P.

Since you haven't specified the model number of your power supply unit or the other components in your system it's difficult to say.

Sorry the model is the W0379RU (i know since it's the one with the 1x 6+2 pin and 1x6 pin and has 2 12 volt rails. but your saying the TR2 will work with it?

What are the rest of the components in your system?
What is the CPU?
What is the motherboard?
How many hard disk drives?
What and how many CD/DVD/BR drives, if any?
How many SSD's if any?
How many CPU & case fans?

You might get lucky and it'll run if everything is running at stock clock speeds (i.e. no overclocking of CPU and/or GPU).

If you run at maximum CPU and GPU load your +12 Volt rails will be producing very close to its maximum output. Its not recommended to stress a power supply like that for any length of time.

my CPU Fan runs at 100%/Full RPM since my motherboard does not have a 4 pin CPU connector? so yea. i have everything at stock but would you recommend me getting this ($120 comon lol) and risking my PSU or should i say forget it and just get a 5750/gts 250 for 120-130?

I don't trust Thermaltake PSUs all that much not that I am a hater of that brand even though I recently bought a cooler from them and got one of their rather pricey cases.
I wouldn't try it with a 500w unit unless that I knew that it would remain cool during use and that it is a high quality unit. Sure I am rocking a gtx 460 and a 8800gt off a 550w unit but mine is rated at 85% and remains cool during use. If you do try be sure that the psu remains cool and isn't developing hot spots. I have found some to get rather hot only to open them up to find potential shorts and points of failure.

That power supply isn't certified so it's unknown if it can even deliver the claimed 420W (35A) from the combined +12 Volt rails.

I haven't seen any test reviews of that power supply so my suggestion is to avoid the risk.

What nation's currency is the $120 - $130 budget range in?

If it's US or Canadian dollars you can look at the Radeon HD 5770 and with a rebate it can be had for less than $100.

You can also consider a GeForce GTS 450.
February 8, 2011 10:33:43 PM

yes it's Canadian but the cheapest 5770 i can find (i have to buy in store, no money on paypal) is 149.99 so yea.

I live in Canada too.

I usually buy on line from NCIX.com or Newegg.ca.

I don't have a PayPal account either. I use a credit card or direct debit from my chequing account.

You also need to factor in transportation charges.

You should try to get a price match from the brick-and-mortar store that you deal with.

Brick-and-mortar store? what do you mean and i ussally buy off of newegg.ca but im only 15 so i don't got a credit card and i don't have any money in my chequing account i use savings... lol

Brick and Mortar refers to retail shops that are located in a building as opposed to an online shopping destination, door-to-door sales, kiosk or other similar site not housed within a structure.

NCIX.com and Newegg.ca are online shopping websites for computer parts.

oh okay. well have you heard of Canadacomputers? thats the store im using there located in a bunch of areas but im going to the ottawa one. well there price for the EVGA gts250 is better than newegg.ca (newegg is about 149 i think and CC's is 109.99

Yes I have heard of Canada Computers & Electronics. That's a good price for that card and it will work with your power supply.

The EVGA GeForce GTS 250 1GB (01G-P3-1158-TR) you're looking at is a different model number than the slower 01G-P3-1145-TR version at Newegg.ca.

I don't know if your budget included HST & GST or not. The province I live in rejected the HST.
February 9, 2011 1:20:51 AM

Really They rejected HST thats good i guess? but yes im taking the taxes into consideration. but just wondering whats better the gts 250 or 5750 just wondering becuase that gts 250 is ALOT cheaper than the 5750 i want or i could get a 5670 but i don't really want that since it doesnt require a 6pin or 8pin connector.

That sapphire one does but not in stock and the one i want is still sapphire but its the vapor-x version.
