Any 500-600w PSU will do the job. My rig can get enough power from a 500w PSU, and that's with GPU and CPU heavily OC'd and both in heavy load.

Any 500-600w PSU from this list will do the job just good.

Just one little question, and tho it might sound a bit hypocite... why 2 GTS 450's? For a bit more you could get a 560 Ti which beats them and you can still add a second one down the road.

A quality 500/550w would do the job.

Antec, corsair, seasonic, XFX are all good quality PSU's.

You could use this list and find one that is in your budget: http://www.overclock.net/power-suppl...-supplies.html

Hope that helps

With around $200 he could do SLI 460 which is better than a GTX 580.

EDIT:

If you're still set with the GTS 450 SLI, then a 550w PSU is more than enough, if you were able to get yourself a couple of GTX460s then a 650w would be a better option. Anything higher would be a waste of money. Inb4the550w+ posts

95$ with rebate. Your best bet at a quality PSU that can power what you want and leaves room to upgrade

I disagree with the bolded part. For some PSU's you might even get less efficiency (higher power bill), and if you do not plan to upgrade, wasted money, both in short and long terms.

Here is a $65 CAD+$25 USD Rebate, a $63 CAD PSU, a $50 CAD, and hell, if he wants to get SLI GTX 460's he can even get away with this $60 CAD PSU or this $74 CAD PSU without skimping on quality.

If you are sure you plan to upgrade to something beastly, like SLI 570's, then yes, a 750w PSU is in order. Otherwise you do not need that much power.

Better spend those extra bucks in a better video card. SLI 450's are hella good, but if i had the chance to pick again and were not interested in BOINC/F@H, i'd pick a single 560 Ti. A bit less power consumption, a bit more performance, and you can add more performance by getting a second one when you can afford it. If you go SLI 450's you'd need to replace both cards if you need more GPU power.

I also know my PSU is overkill, but it was between buying this one for $85 or get a happy happy boom boom cheapo PSU. As i stated before, i could easily power my rig in full load with a Silverstone ST50F-ES 500w PSU but for that price there are better alternatives, to be honest. It's a hella good PSU tho.

If you looked at the product you would know that ANY psu with at least an 80 PLUS Bronze rating will significantly reduce power consumption. Those ratings are key. it means that there is 80%+ energy efficiency at 20%, 50% and 100% load condition which translates into lower heat output and lower energy bill.

by getting the psu i listed, you are buying a trusted psu that will keep cost down and also give you plenty of room to upgrade at ANY time you choose. i'm simply giving you an option. corsair is easily the most dependable PSU brand on the market

EDIT: and the reason the PSU's you listed are so cheap is because they come with a CLUSTER of cables you CANNOT detach no matter how many you actually need. Modular is the way to go for increased airflow and also less of a PAIN IN THE ASS

That's fair, but he lives in Canada.

Anyway, he said his friend is dead set on two GTS 450s, so he will never have a need for the TX750 "V2". Even so, by the time he needs that much power, there will be something significantly better out on the market in this budget and it will probably even be modular (that is, with the way things are going right now with PSUs).

Therefore, I recommend these:


Now, these shipping costs could be skewed because I am in the USA so I think it's saying that this how much it would cost me based on where I live.

Regardless, all of these are very solid units - even the Rosewill Green Series- and I guarantee that any of them are enough.


Edit: when you're on a budget, you're better off focusing your search on non-modular PSUs. However, the 550W Antec TruePower New is a high-quality semi-modular PSU!

Then why are you recommending a non-modular PSU? I mean, the Corsair TX series are all non-modular.

GTS 450's in SLI call for 35A/600W; a Corsair GS600 (48A/600W) can be had for $79:
