Hey everyone, I recently purchased this PSU and I know it isnt a reliable brand so I may even return it and purchase a better and more reliable one.(http://www.coolmaxusa.com/productDetailsPower.asp?item=VL-600B&details=spec&subcategory=140mm&category=single) and I checked the specs on their site and they thoroughly confused me. I want to know if this is compatible with a Zotac GTX 650 Ti 2gb GPU. From the site I purchased that gpu they said I would need 450 watts. On the PSU site I dont really understand what they are saying (refer to the link) they have the two wattages seperated (160W and 450W) so I assume those are the rails but will the 450 one cover the power my GPU will need and will 160 cover the rest of my pc? Please forgive my lack of knowledge, I was never that good when it comes too computers. All replies are greatly appreciated.

SYSTEM SPECS

Zotac GTX 650 Ti 2GB ddr5
AMD athlon II x4 3.00ghz 640 Processor
8GB of ddr3 RAM
If you need more which I assume you might then please just ask.

Yes! please do yourself a favour and return that pos.
What is your max budget for a power supply?
And where do you live(country)?

Hi again Sean !
I'm in Ontario, so it was getting past my bedtime last night lol!
Looks like Toy explained, quite well, how horrible Coolmax units are.
He linked the XFX 550, which I just purchased for a clients build.
And the Corsair CX500 is good too,installed that in my buddy's 7870 rig in July.

I live in Canada. If I return the PSU I will have a budget of around 60-70 dollars (Taxes EXCLUDED because Canada loves to raise those as high as they come). If I were to keep the PSU, would it work? (I dont plan to risk it if its truly the POS I have heard about).

Even on their site they say the total wattage is only 581. You also didnt really answer my question but thanks for trying I guess.

Here are some Coolmax products that were tested by trusted review sites, Hardware Secrets and jonnyguru,

Thank you very much. You are right. I really don't want to risk that. I suppose I will return the item within the 30 days from when I purchased it to "Future Shop". Can you please reccomend me a PSU that is reliable and not too pricey? I will have around 60 to 70 Canadian Dollars for the budget. I would really prefer something in that range. I also have never installed a PSU before but I have heard it is not very complicated so Ill be installing it myself I assume. I hope to get some opinions, thank you, toyftw.

Hi again - Installing is easy. Just google it(installing pc power supply, or removing and replacing PC power supply). There are several good tutorials and youtibe videos as well.

I'll look for some PSU's now & post here. That's alow power usage card, so there will be np problem finding a good
one in your budget range.

Both good solid choices - choose the least expensive. You could also try canadacomputers, but these are good deals, and are probably good for a few days.

Hi - Total watts is misleading - the +12v amps is the key spec, but all the PSU's I linked above are 450w or greater with more than enough +12v amps.

Ah, no the 450w is total sytem required wattage, not the gpu alone. Your system needs 24 - +12v amps, the VP450 has 30 - +12v amps. The CPU & GPU draw their current from the +12v rail(s), that's where the power needs to be.

Every PSU I linked will work well with your system.

Thank you, I really appreciate your help. Ill be choosing the XFX Pro and returning this garbage supply back to future shop. Unfortunately I called them while my item was being shipped because they had lowered its price on their site by over 25 dollars. I was refunded the money into my visa and now when returning it the invoice (Reciept) will show the original price so I assume they will give me the full price but I dont know if I say that I was refunded some of the money due too a price drop. Hopefully I dont have too many problems with their employees. Ill be choosing your post as the solution. Thank you.
