i want to buy a psu for Gigabyte gtx 970 G1 Gaming, which one will be great and what G1 G2 GS mean ?

There are two big differences between the G1 and G2: 1. the G2 is a single-rail 12 volt design (this is the most important difference), and 2. the G2 is made with better quality components, e.g. solid aluminum Japanese capacitors. The G2 is absolutely worth the extra cost.

I actually have the same GPU and this one runs it perfectly. I'm pretty sure G1 is just a series of Gigabyte products such as GPU and MOBO.

If you have a gaming rig. I would go with at least 1000watts. Video cards, fans, cpu, and even external USB devices can consume some power. I have a supernova 1300. I love it. The G2 is what series number it is. G2 is a newer version

To find what best fits your setup. Search for power supply calculator in Google or other search

not sure but this is a pretty cheap PSU...i wouldn't risk my GPU with it. Just buy a new better PSU they are not very expensive

Since you can't do any real hardcore gaming with this card, a 300-350 Watt power supply will work on a system with a single hard drive, DVD-RW and basic CPU heat sink. Anything more advanced you'd want to look at at least a 400-450 watt power supply (if you're running 3+ fans and more than one hard drive, you should already have at least a 400 watt power supply). As always, try to stay with name brands when it comes to a power supply. Antec, Corsair, EVGA and OCZ are all reliable but in a pinch Cooler Master and ThermalTake will do.

Should work with good power supply, but I newer try. Ask to Gigabyte support team.

The PSU is a Logisys brand PSU, it doesnt have a model number listed on it. As for reliability its a decent PSU it has basically what you need, if you want more cable options I would buy a different PSU then.

Not only is it a higher wattage (1000w vs 750w) which will give you more power for high-end graphics cards (like the 770gtx), but it is Bronze rated, meaning it is very efficient (http://en.wikipedia.org/wiki/80_Plus). So yes, it is a much better power supply.

According to Rosewill's site it supports Cards up to 280mm in length. I just put in a Reference GTX 770 over the weekend, which is 266.7mm in length and it was a tight fit. A Gigabyte G1 Gaming GTX 970 is about 9.3 inches (or 236.22mm) in length. So you should be just fine.

As far as the overall watts are concerned, this is enough. There's also enough plugs for all of that (with room for another graphics card or two if you wanted more later). You should be just fine! I love this PSU. Highly recommended.

EVGA SuperNOVA 1000 P2 80PLUS has a rated efficiency of 92% while G2 version is rated for 80 Plus Gold which is less efficient then Platinum P2 Version. Also G2 version does not have lot of bells and whistles as P2 version such as ECO Mode if you want your PSU to be dead silent. I hope that helps. For efficiency safe and if money is not an issue, EVGA SuperNOVA 1000 P2 Power Supply is one of the best PSU on the market for 1000watts.

Nope, the GTX 970 G1 is 12.23" and the HAF-912 only has 10.55 (ish)" available behind the PCI-E slot, sorry... :-(

No idea but everything I've ever had from them has been rock solid, and this psu is fantastic.

It's 1 6-pin and 1 8-pin. Note that it's highly advisable to use a PSU that uses a single +12v rail, and a bit above the minimum stated watt requirement of 500. The SeaSonic G Series 550-Watt is one I've heard recommended pretty heartily.

Depends on what gpu you have. But do not buy this psu. Mine broke as soon as the warrenty was over. Get a corsair trust me.

550W is not enough for this card and all the other components in your PC. Technically your PC will run, but the power supply will be maxed out quickly when playing a graphically-intensive game and you won't get full power out of your hardware and so your performance will suffer (remember, you only get 80-90 percent of the power from a high end PSU, so you are only actually getting 450 or so watts from this PSU). You should get a 700-750W minimum to ensure you are not wasting money on the graphics card. Also, don't buy the PSU used - as another person noted it won't have a warranty and you presumably won't know how many hours have been put on the PSU and so it's life could be considerably shortened. 550W is not enough for this card and all the other components in your PC.

If the Platinum (1000W) and Gold (1050W) were the same price; I'd have no problems recommending the platinum over the gold rated PSU. If you are paying a premium (regular retail prices) for the platinum, it simply isn't worth it unless you are going for the extra warranty period. The power savings between the two PSU's would not be worth the price difference in my opinion.

I have a 300w PSU as well as this card installed, 2 HDD (2TB+320GB), i7 4770 CPU.. (prebuilt Acer) For a few months everything worked fine and now I constantly get BSOD's, ticking hard drives and random restarts. Would definitely recommend at least a 450w or greater PSU. Spend $45 more and get a gtx 750 ti, its better and requires less power than the gt640.

The EVGA is definitely more reliable especially the P2 series they are based off the Leadex Platinum platform. The evga p2 1000 has one of the lowest ripple rates and best voltage regulation of any 1000 watt plus power supplies and one of the best power supplies period. Low ripple rates means your pc parts last longer and have alot less chance of dying due to power supply fluctuations combined with the voltage regulation also means this is a killer power supply for overclocking.
