Low power HD 7770?

MeicoPotato · Jan 4, 2013

Does anyone know a Radeon HD 7770 that uses little power? My power supply is only 250W.

andrewcarr · Jan 4, 2013

No such thing. Either you'll have to upgrade the PSU or settle for a 7750 or 6670.

andrewcarr :

Do you think the ASUS 7750 one will be good?

andrewcarr · Jan 4, 2013

ASUS cards are good just make sure if you get a 7750 it's the GDDR5 memory version not the DDR3.

What brand of power supply? what is the make and model?

These are my specs: http://h10025.www1.hp.com/ewfrf/wc/document?docname=c02628226&cc=us&dlc=en&lc=en&product=5049513#N65

Well if you live in the US a cheap and good model is a Corsair CX 430.

I have that same PSU running my computer at the moment and haven't had a problem. It can handle up to the 7850. The rebate does work but it takes about 4-6 weeks.

I'm upgrading my graphics card for gaming.

Is there a lot of difference between 7750 and 7770?

andrewcarr · Jan 4, 2013

Well here's an idea of how it'll perform (these are reference cards) at stock clocks.

Is 10 FPS a big difference?

...sorry, lol. I'm a newbie

jnkweaver · Jan 4, 2013

about 2-10 fps depending on what resolution and what game. The 7750 is a good card.

MeicoPotato :

About 20% difference.

Get the Antec VP450.
http://www.newegg.com/Product/Product.aspx?Item=N82E16817371045&Tpk=vp450

It is actually easily able to provide up to 530w of power. The CX430 is just low quality.

andrewcarr · Jan 4, 2013

It all depends on how you look at it. Normally for selling for only a bit more than a 7750 the upgrade to a 7770 is a good deal but if you factor in the PSU that it'll require the value goes down.

I would be looking at the Performance preset which is 1920 x 1080. Then also consider if you'll be overclocking the card or not. If you want that bit extra then the 7770 is better but it's $30 more after rebate and $50 more before.

10 FPS can be a bit difference but it depends on where the 10 is. For example if a card runs a game at 80 FPS and another at 70FPS, both are overkill and there would be no difference. But if a card runs a game at 20FPS and another 30FPS there is a significant difference. The 20FPS most would consider unplayable but the 30FPS would be. The normal benchmark for play ability is 30 FPS while most enthusiasts will aim for 60FPS and people that are completely anal will go for the 120FPS (which requires a better screen). 60 FPS is normally the refresh rate of most monitors.

My resolution max is only 1680 x 1050.

If I run...for example...Crysis 2, will I get good framerate on the 7750?

samuelspark · Jan 4, 2013

MeicoPotato :

If you run on low/medium settings. Sure.

MeicoPotato · Jan 4, 2013

Okay, I think I might just stick with the 7750.

andrewcarr · Jan 4, 2013

As for the CX 430 being a low quality unit I beg to differ.

http://www.techpowerup.com/reviews/Corsair/CX430_V2/8.html
It also can hold 515W of power.

The other PSU is by no means bad but in the long run it costs more.

Dijas · Jan 4, 2013

MeicoPotato :

Well I can't say for sure, but I have the 7770 and at a slightly lower res I get 50-60+ fps on max possible settings.

It should run reasonably well, but you may have to lower it a bit.

samuelspark · Jan 4, 2013

andrewcarr :

It's pretty mediocre. It's a SuperFlower OEM I think.

andrewcarr · Jan 4, 2013

I'd say medium settings if you don't touch the AA. Where the 7770 would be high without touching AA.

As for the comment above, install the high resolution pack which enables DX11 and you won't touch max settings (even stock I doubt you are at true max).

MeicoPotato · Jan 4, 2013

Maybe I should get a new PSU anyways.

I'm on a very tight budget though, so is there a PSU that's about 450W that is dirt cheap? (20-25 bucks)

andrewcarr · Jan 5, 2013

Not that'll actually supply 450W. I listed the CX430 because it's the cheapest PSU I can recommend. You want to stay away from off brands for PSU's.
http://www.newegg.com/Product/Product.aspx?Item=N82E16817139026&Tpk=CX430
It's $20 after rebate at least.

jnkweaver · Jan 5, 2013

Dirt cheap power supplies are not worth the money. They die quickly and take other components with them ie. cpu, motherboard, and graphics card. Wait until you have the money to buy a decent one ($40-60).

shadow_city · Jan 5, 2013

Just letting you know, I have tried to play Crysis 2 on a 1680 x 1050 monitor with an E8300 at "Very high" settings at 40 fps. So no problems. It does ultra at 20 fps

Note: Lowest is high then very high, extreme, ultra

MeicoPotato · Jan 5, 2013

My very last question is very important.

Will this graphics card: http://us.ncix.com/products/?sku=74741&vpn=HD7750-1GD5-V2&manufacture=ASUS&promoid=1033

...work with my motherboard? Here is my motherboard specs: http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c02560084&printver=true
