Will my 650W PSU be enough to power my system if I purchase a Radeon HD 7870?

Question asked by Kevin from Zaire | Answered by Anthony Garreffa | Cases, Cooling & PSU Content | Posted: Oct 19, 2012 3:50 am

I want to know if my 650W power supply will hold up?

 

I've got the following:

  • Core i5 3570
  • Cougar 650W CM PSU
  • 8GB DDR2 1333
  • 3 HDD's and a CD Rom
  • A PCI Wifi card
  • Cooler Master Gemini II S524
  • GIGABYTE GA-Z77X-UD3H

 

I want to buy a GIGABYTE GV-R787OC-2GD as it is on special, but want to know if my little 650W power supply will be able to handle all of this.


Hi Kevin,

 

Will your Cougar 650W power supply hold up if you were to add a Radeon HD 7870? Yes, most definitely. Most people think that because their system has a 650W power supply, that you would use close to that with a video card installed - but in the real world, most systems don't even get close.

What that type of system, in a stressful game such as Battlefield 3, I'd be surprised to see you pushing past 200-250W of actual power consumption. You could even stretch out to the HD 7950 or 7970 and still find you'll have enough juice left to spare. The new 28nm-based GPUs are incredibly power efficient, as are the new CPUs that have arrived over the last 6-18 months.

 

Your 650W PSU will hold up, for sure - now go out and get the HD 7870!

I want to buy a new monitor for gaming and photo editing, should I get a 1920x1080 @ 120Hz screen, or 2560x1440 @ 60Hz screen

Question asked by Michael from Philippines | Answered by Anthony Garreffa | Displays & Projectors Content | Posted: Sep 19, 2012 7:25 am

I would be buying a new monitor.

Which would you recommend better?

 

An 1920x1080 120hz 2ms or 2560x1440 60hz 6ms?

 

For gaming and photo editing.


Hi Michael,

 

A 1920x1080 @ 120Hz screen is great for gaming, but they're all based on TN panels which aren't really known for their great image quality when it comes to users who want to do anything involving photo or video editing. For gaming, they're some of the best screens out there because of their doubled refresh rate, especially when you're reaching 120 frames per second in games.

I personally run 120Hz screens at home, and I would never go back to 60Hz screens for games - they're that good. But, and this is a very big but, 2560x1440 @ 60Hz screens have their place in the market, too. For image- and video-related work, they're second to none. Especially with photos, as you're working with color and want to see the color on screen, as close to the color as you took, in person, so that you're working with the best possible quality.

 

Dell's new AH-IPS panels, the Dell UltraSharp U2713HM are probably the best to go for, if you haven't checked them out I suggest you do. They're not too badly priced, either.

Should I upgrade my GeForce GTX 460 SLI setup to a single, faster GPU on my 1080p setup?

Question asked by Woody from Israel | Answered by Anthony Garreffa | Video Cards Content | Posted: Sep 18, 2012 2:18 am

Should I upgrade my GTX 460 SLI (1GB each) cards to a newer gen card?

 

I overclock both cards constantly to 100MHz higher than stock to gain a bit more performance in newer games. I'd obviously like better performance! But I haven't seen any benching of my cards versus newer ones. That's to be expected, and I can compare to 560s or something anyway. But I don't have a definite idea of what's best to choose.

 

I run a 1080p monitor, and have an i7 920 @ 2.67GHz.

 

Any help would be great!


Hi Woody,

 

The GeForce GTX 460 SLI setup that you currently run is definitely ample enough for today's games, but there are also benefits of upgrading, too. Let's say you were to grab yourself a new GEFORCE GTX 670, this would give you a reduced power consumption compared to your SLI setup.

 

TweakTown image asktheexperts/5/4/54_09_should_i_upgrade_my_geforce_gtx_460_sli_setup_to_a_single_faster_gpu_on_my_1080p_setup.jpg

 

Secondly, it would give better performance as the single GPU can go right up to 100% usage, compared to some games, where you might see maybe 75-80% usage per GPU, not maximizing your setup. Thirdly, you would drop any current issues you experience with SLI, as there are some issues, with some games with multi-GPU use.

 

For pure performance, you're looking at an improvement, that's for sure. Two GTX 460s are equal to around a single GeForce GTX 480, and a GEFORCE GTX 670 is around ~30-40% faster than the single GTX 480, all while using less power, and producing less heat and noise. I say go for it. It'll also give you the chance to upgrade to GTX 670 SLI in the near future, too.

Which RAM will give better performance with Z77 board, 2 x 8GB or 4 x 4GB?

Question asked by Carlos from Australia | Answered by Anthony Garreffa | RAM Content | Posted: Sep 11, 2012 6:49 am

Which RAM configuration will give better performance in a Intel Z77 Board. 2 x 8GB, or 4 x 4GB?


Hi Carlos,

 

Both options are fine, you'll notice no performance difference between either option. I will suggest going for 2 x 8GB sticks of RAM, which is the more expensive option. This will allow you to upgrade in the future to 32GB, if that's something you're after.

 

TweakTown image asktheexperts/5/3/53_10_which_ram_will_give_better_performance_with_z77_board_2_x_8gb_or_4_x_4gb.png

 

Performance-wise, you will not see any differences. If you were to end up moving to a quad-channel-based system in the future, all you'd need to go is get another 2 x 8GB sticks and you're ready for quad-channel.

I have an Intel Core 2 Duo e8400 CPU with Radeon HD 6770s in CrossFire, should I upgrade my CPU or GPU?

Question asked by Aaron from Australia | Answered by Anthony Garreffa | CPUs, Chipsets & SoCs Content | Posted: Sep 6, 2012 6:22 am

I currently have a core 2 e8400 and 6770's in xfire. I want to update to be able to play battlefield 3 smoothly. with limited funds to upgrade should I hold off and upgrade to ivy bridge or swap my xfire setup for a GTX 670?

 

Cheers


Hi Aaron,

 

Battlefield 3 is quite demanding, and is one of only a handful of games that truly uses your CPU and benefits from a faster CPU, or more threaded CPU. Your CPU is definitely your limitation, firstly, it's an ageing Core 2 Duo, secondly, it's only a dual-core chip.

Your GPU setup is more than good enough to run Battlefield 3 at medium-to-high settings at 1920x1080, so I would suggest waiting and upgrading to an Ivy Bridge setup. You could get a decent Core i5, 4-8GB RAM and CrossFire-capable motherboard for only a little more than what a GEFORCE GTX 670 would set you back.

Should I buy a gaming notebook, or desktop to plug up to my Full HD projector setup?

Question asked by Parichya Gautam from India | Answered by Anthony Garreffa | Video Cards Content | Posted: Sep 4, 2012 5:33 am

I just have a little query here , supposing i had the option to buy either an Alienware M17x R4 (NVIDIA GT 680), or make my own desktop with similar GPU, which option will be more beneficial ( keeping the electricity consumption in mind ) ? and, assuming that i use the Laptop as a CPU only (using external FullHD projectors, audio systems etc ) .


Hi Parichya,

 

Gaming notebooks have their place in the market, and I would recommend the Alienware option if you were a gamer who moved around. If you were going to LAN parties, or friends' houses to LAN, then the Alienware notebook would be the way to go, but for you, I would recommend the desktop.

 

TweakTown image asktheexperts/5/1/51_10_should_i_buy_a_gaming_notebook_or_desktop_to_plug_up_to_my_full_hd_projector_setup.jpg

 

Power-wise, it will use a little bit more, but if you purchased power-efficient hardware, it shouldn't be too bad. You could get yourself a great Core i7 system, with a GEFORCE GTX 680, and have a much, much faster system, all while costing less!

 

Considering the system you're using is being used as a standalone box, with projectors and audio systems plugged into it, a notebook seems really out of place. A desktop on the other hand, would feel perfect, drop it down somewhere, plug it in and go!

Should I upgrade my GeForce GTX 560 Ti SLI setup to a new GTX 670 or GTX 680?

Question asked by Duarte from Czech Republic | Answered by Anthony Garreffa | Video Cards Content | Posted: Aug 31, 2012 5:33 am

Is it worth to upgrade from a gtx msi 560ti oc SLI system to a new gtx 670/680?


Hi Duarte,

 

Good question, with a simple answer: no. Your GeForce GTX 560 Ti setup is still quite good right now, and would be close to the performance of a GEFORCE GTX 670 or 680 on their own. If you're after more grunt, I'd wait for next-gen GPUs, or look at upgrading your monitor setup.

 

TweakTown image asktheexperts/5/0/50_10_should_i_upgrade_my_geforce_gtx_560_ti_sli_setup_to_a_new_gtx_670_or_gtx_680.jpg

 

Say you're running a 1920x1080 resolution, your GTX 560 Ti SLI setup is fine for virtually all games out right now. Your SLI setup would only need to see an upgrade as your resolution goes up. Your VRAM would be used up, and then you'd have a reason to upgrade your GPUs. I would suggest investing the money from a GPU upgrade into two more screens, giving you a Surround Vision setup.

 

Your GTX 560 Ti SLI setup would still be more than powerful enough to run the three screens, and as time goes by, upgrade to a couple of 670 or 680's when they get cheaper.

My SSD is hanging on system start-up on my ASUS P8P67 motherboard, should I disable Intel Rapid Start technology?

Question asked by Rolando from Paraguay | Answered by Anthony Garreffa | Motherboards Content | Posted: Aug 31, 2012 4:52 am

Hello, I have a p67 pc, corei7 2600k, 8g of ram, asus p8p67 mb, gf 570gtx gpu, 850 psu, I just bought a Vertex 4 ssd as my windows drive, the problem that Im having is that the drive hangs when the system stars, I've read that it has do to with the Intel Rapid Storage technology that has my pc, so how do I disable this?


Hi Rolando,

 

Before you disable Intel's Rapid Storage Technology in your motherboard's BIOS options, I would suggest updating the drivers for the Intel Rapid Storage Technology from ASUS' website. This seems to fix most users' issues with the drive hangs and problems.

Would a CoolerMaster Silent Gold 800W run two GTX680's?

Question asked by Andy from Australia | Answered by Anthony Garreffa | Cases, Cooling & PSU Content | Posted: Aug 29, 2012 8:12 am

Would a CoolerMaster Silent Gold 800W run two GTX680's?


Hi Andy,

 

Yes, the CoolerMaster Silent Gold 800W is an excellent PSU, and would be most capable of driving your SLI'd GEFORCE GTX 680 setup.

 

TweakTown image asktheexperts/4/8/48_04_would_a_coolermaster_silent_gold_800w_run_two_gtx680_s.jpg

 

NVIDIA have also done quite well on power consumption levels on the Kepler-based GTX 680 GPUs, meaning they use less power than the older generations of GPUs at the high end, and under stress. If you already have the GPUs, the CoolerMaster Silent Gold 800W is a fine PSU to acquire.

Would an i5 3570K bottle-neck a 2-way SLI GTX 680 and a 2-way SLI GTX 670?

Question asked by Megs from Philippines | Answered by Anthony Garreffa | Posted: Aug 27, 2012 8:19 am

Would an i5 3570K bottle-neck a 2-way SLI GTX 680 and a 2-way SLI GTX 670?


Hi Megs,

 

Double-edged answer, so yes and no. For a single-screen gamer, no it wouldn't. If you were to be on a triple-screen, 120Hz setup, then depending on the game yes.

 

TweakTown image asktheexperts/4/7/47_01_would_an_i5_3570k_bottle_neck_a_2_way_sli_gtx_680_and_a_2_way_sli_gtx_670.jpg

 

For the most part, the Core i5 3570K is absolutely more than enough. If it's not enough, then a bit of overclocking would definitely push you over the edge and give you that bit extra grunt that the SLI setup would require.

 

I'm going to guess that you have a single monitor (or TV) setup at 1080p, so if you do, then the CPU is fine.
