Planning to upgrade - Help needed regarding PSU

[jits]

Hello,senior members.....I'm planning to upgrade my old PC, for playing the latest games. I have two graphics cards in my view - AMD R9 270x 2GB DDR 5 or Nvidia GTX 960. Both of these need at least 600wt as far as I know, so I'm going to buy Corsair 650Wt PSU for that. Presently I have APC Back-UPS 600. If I go with either of these cards and the Corsair 650Wt PSU, do I have to go for a new UPS too?? I'm worried as we have frequent voltage fluctuation in our area..... and also I don't have AC in my room, so I have to depend upon CPU coolers only. And also,how much the electricity bill will be affected with this 650Wt PSU???

I think a Corsair 500W-550W PSU is already good enough. Try using this >PSU Calculator< from Cooler Master to find out exactly but if you have spare cash then go for the 650W. Regarding the UPS, I dont have knowledge on that... Sorry. Best of luck with your upgrade, hope someone can help you about your concern on your UPS.

Follow http://www.sevenforums.com/tutorials/180324-system-info-see-your-system-specs.html to fill in your System Specs with as much info as possible. We're looking for something like the example below:

As for the PSU, follow what Ian said. Remember to always buy 80Plus certified PSUs so we can be safe.

As for that UPS, I wouldn't need to buy a new one. It is the PSU that will give juice to the components inside a system unit and not the voltage regulator.

The 650W psu doesn't actually use 650W all the time - it's the maximum it can supply (although in practice psu's are 80-90% efficient). The psu delivers however much the pc draws, up to its max rating. So swapping out a 650W psu with a 800W psu will not use any more electricity at the mains socket. The pc uses more electicity when say encoding a video (high cpu) or hard gaming (high gfx).

When calculating psu watts, it's a good idea to go for a slightly larger capacity than the bare min required, to give yourself a bit of extra headroom. However - don't go crazy and get a psu that's way larger than you need, because a (say) 1500W psu running at 30% of its rated capacity is less efficient than a 650W psu running at 75% of its max. In that scenario, on the same pc, the larger psu would use a bit more electricity.

Thank you all for your answers...
@IanDrexP - Yes I'll certainly go for a 650Wt PSU,Corsair, if the budget allows me.
@RoasterMen, I've used the utility and edited my system info...some places are blank still, I hope to get my new system in the next week,and then fill up the new specs.
@badcrc,I'm definitely not going to buy anything larger than a 650Wt PSU...I think my budget allows me to go as far as 650Wt only.
Thank you all again for these prompt replies.....

Hi,
EVGA has a nice line up of P2 models that are A lot cheaper than Corsair and just as good
EVGA - Products - Power Supplies

I also recommend EVGA, Corsair doesn`t even make their power supplies.

EVGA - Products - EVGA SuperNOVA 550 GS Power Supply - 220-GS-0550-V1

EVGA - Products - EVGA SuperNOVA 650 GS Power Supply - 220-GS-0650-V1

EVGA - Products - EVGA SuperNOVA 750 G2 Power Supply - 220-G2-0750-XR

Doesn't matter who makes them, they're top quality PSUs.

Jits:

Before you buy ANY power supply, tell us what brands and models in the 500 to 650 watt range are available to you from your suppliers.

Or better yet, post a direct link to your suppliers so we can see what they have to offer.

As far as I can remember EVGA power supplies haven't been on the market that long so I really don't know how good they are.
Corsair power supplies have been here a long time with a outstanding reputation.

Quality is good but they are well overpriced seems to me :/

 

[AddRAM]

I know they are good (anything above a 650 that is) I have an HX750 It`s just a trade name.

You guys are so easily provoked :roflmao:

I just checked the stock at Flipkart, a major PC component supplier in India.

Of the brands well known in the USA, they carry only Corsair, Coolermaster, Seasonic, and Antec.



I looked through what they had for each of those brands, 500 watts and up, and checked who actually made each of the available PSUs.

Corsair: best candidates are the RM550 and the RM650. Both made by Channel Well, fully modular, and 80 plus Gold.

Coolermaster: the V550/V550S is a good unit with all Japanese capacitors, quiet, and highly efficient at low loads. But it’s not available at Flipkart.

Antec: There are 6 available, but I’m not sure about any of them. Maybe the EA 550 Platinum?

Seasonic: S12G-550 and S12G-650; both semi-modular and 80 plus Gold.

Of those, I go with the Seasonics or maybe the Corsair RM series.
