PSU advice needed! Any help wanted!

Postposted on Tue Jan 07, 2014 12:32 am

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/productDetail ... sp?item=...) 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.

Coolmax? Never heard of it. You should really stick with well-known brands such as Seasonic, FSP, Thermaltake, Corsair, Cooler Master, ACBel, Silverstone, Enermax, etc. Don't gamble on 'dark horse' PSU providers because your PC's operation depends on a good PSU.

Power Supply is one of the last things that you want to go skimpy on with a PC build. You are going to create headches via instability and a potential fire hazard (cheapo PSUs typically lack some safety features). You don't have to allocate a ton your budget to get a decent unit either. Any of the no-frills units from reputable ODMs and OEMs work fine without spending an arm and leg. You'll thank yourself later.

Just buy a Seasonic. A 550 or so would do.

You do not have to get a Seasonic PSU.
The Corsair PSUs are made from quality parts with many made by seasonic like my TX-850.

I always recommend a little more psu then you actually need so it is not running above 70% capacity all the time.

The Corsair CX-600 for $69 is a quality Psu with 2 6+2pin graphics card power connectors, if you want a modular PSU the Corsair CXM-600 costs $79.

I usually recommend modular PSU's if it is a small case with no room for cable management, if you have a large case save 10$ and get a non-modular PSU.

Ummmm... TR's 650 Ti review system with an i7-2600K sipped 143W under load. That's 24% of 600W (nowhere near the 50% peak efficiency) Irregardless, I'll back up the recommendation for a 500-650W PSU because it leaves the door wide open to ANY single GPU system in the future. Use a PSU calculator if you want to plan for future upgrades. (GTX 780 Ti perhaps?)

To the OP, if you're looking for something cheap, decent quality, and plenty of power for your system; Corsair's CX 430 is regularly on sale for $20 after MIR (like it is now). Impossible to beat. It's a very popular PSU as you can see by the 1,900+ reviews.

If you're looking for something nicer, check newegg.com for 80 Plus Gold PSUs in the 500-650W range. 80 Plus Gold efficiency gets you nicer internal components and helps weed out a lot of the not-so-great units. Modular is nice if you can swing it.

PSU shopping is simple. Look for a review of your card here on TR and go to the power results (here's one). See what the full load is, then double that and that's the wattage you should get for your PSU. So for your system, you could go with a 400-450w PSU no problem. However, you should me mindful of any future upgrades; if you're planning to get something more powerful you should get a PSU that can accommodate it.
