That PSU should be enough, but it may be pushing it a little. It's not a bad PSU, but it can't deliver nearly its rated power delivery. It can only go up to about 25% lower than what it is rated for according to professional reviews of it, although besides this deficiency, it's a decent PSU in terms of quality.

The graphics card should run any game in your given resolutions at maxed out texture settings, maybe with some MSAA and such too. Those aren't demanding resolutions.

Also, nitpicking a little, but it's a Radeon 7750 GDDR5, not DDR5 (I don't care what the web site says, the site is mistaken because there is not yet any such thing as DDR5, just GDDR5 and its a common mistake) and it is a video card, not a GPU. The GPU is a component on the video card. Sorry, I can be annoyingly OCD about such things.

Well that is a crappy PSU. Would be great to change it to Antec Vp 450 / Corsair Cx 430 V2

And about your system :

65W Psu
50W Gpu
Idk how many ram stick you have but i assume 2 ? 16W ddr3 4W DDr2
15W Hdd
25W Dvd

=171W

It will be good but i still recommend to change that PSU.

Now Antec and Corsair are at 30-35$ both. If you can change it if not plan it !

Your link says that it is a good PSU. I agree that the CX-430 V2 and especially the VP-450 are better, but I probably wouldn't replace it with them. Also, you're way oversimplifying your power requirement math and no offense, but I find some of the numbers to be questionable. Would you mind giving me a source for them? I know from experience that hard drive, optical disk drive, RAM, and motherboard power consumption can all vary significantly even among seemingly similar models and DDR2 modules usually consume more power than DDR3 with the same number of chips.

OMFG again you. GTFO stop quoting me.

Read better last tests 4 and 5 failed. Where doyou see GOOD psu there ?

Ddr3 ram is normally 8W per stick

Ddr2 1.9 W per stick (DDR2 800) http://www.valueram.com/datasheets/KVR800D2N5_2G.pdf

Normal HDD Sata need 15W

Dvd goes from 15-30W

The CPU is at intel WEBSITE

GPU at AMD website

Edit : I just checked that board and it is a DDR2 so 4W .That bring the limit to 160 W cuz i calc with 16 W.

Get 650 W PSU.

Corsair is on sale http://www.newegg.com/Product/Product.aspx?Item=N82E168...

My new gig has a 7970 and 650 is more than enough to power it.

I think a 650W PSU will last you for several years down the road should you decide to build a new machine.

Also, newegg had the GTX 280 for $89 yesterday and it's 2x faster than that 7770. You missed out dude.

Quoted from your link's conclusion:

Quote:
Even though this power supply can't deliver its labeled power, it isn't a bad product for its price tag and targeted audience. It's real power is close to its labeled power (430W) and it's efficiency isn't bad for a low-end product. Plus it has all its protections up and running, a thing sometimes hard to find on cheap power supplies.

If you are building an entry-level PC with just one or two hard disk drives andjust one video card - or even maybe with an on-board solution - this power supply is a good option.

It is better than other low-end products that we've reviewed.

In sumary, the only real flaw from this product considering its price range is its wrong label; this power supply should be sold as a 430W unit. Nonetheless we think this can be an option for the average user that doesn't need a lot of power and doesn't have the money to buy a better product.


Sure, it's not being praises as a savior, but it is specifically said to not be a bad PSU.

Your link states the voltage, not wattage, of that DDR2 stick. Saying 1.9W isn't even backed up in any way that I saw.

HDDs vary significantly in power consumption. Common variance is currently from about 5W to over 20W, but some models are a little above or below that range. Saying just 15W is misleading.

Similar can be said for an optical disk drive, although the range is generally higher than hard drives. I'd say that your number is for a DVD drive, although more accurate than your nubmer for hard drives, is still not quite adequate.

Intel's site doesn't specify power consumption for any of their CPUs. You can read TDP there, but TDP and power consumption are not the same.

The above is true also for video cards.

The GTX 280 is not anywhere near as twice as fast as the 7770. In fact, it is slower than the 7770 overall.

OP most of here isn't really answering ur answer...

anyway, if u can afford 7770, it is a very solid low-mid end card, u should can run most game in low/med settings in 1080p, and higher quality if ur monitor resolution is lower than 1080p, and the PSU u having now should have no problem running 7770 as it is a very efficient card

Power 1.975W (operating)

Now srsly GTFO . U keep irritating me with ur stupid answers that EVERYONE know they are true except you .

You are wrong really wrong about that.

I wont respond anymore to your quotes so i wish you a BAD luck.

I missed one thing and that was because it didn't render properly in my web browser. Oh boohoo. Since you say that you won't respond back, the answer is obvious, but how could you ignore everything else that I said? Even better, your English fail states that everyone knows that my stupid answers are true except for me. Real nice there.

If you're going to be immature about being wrong on most accounts, then by all means act how you want, but don't expect me to act any better towards tyou when I have to correct what you say due to inaccuracy in your claims.

Regardless, OP's current PSU, although pushing it, should be fine and the 7770 should be an adequate upgrade for OP.
